MAJOR ADVANTAGES OF

CAST IRON SOIL PIPE

SOUNDPROOFING QUALITIES OF CAST IRON WITH RUBBER GASKET JOINTS

One of the most signiﬁcant features of the combination of cast iron pipe and compression gasket and the hubless coupling joint is their sound-deadening qualities. The problem of noise is particularly acute in multi-family housing. Although soundprooﬁng has become a major concern in construction design, certain plumbing products have been introduced which not only transmit noise, but may actually amplify it. The use of neoprene gaskets and hubless couplings with cast iron pipe and ﬁttings signiﬁcantly reduces noise and vibration. As a result of the composition and structure of the cast iron, sound is mufﬂed rather than transmitted or ampliﬁed, and the neoprene separates the length of pipe and the unit of ﬁttings so that they suppress any contact-related sound. The result is that objectionable plumbing noises are minimized.

ECONOMIC ADVANTAGES OF CAST IRON PIPE AND FITTINGS

The properties of cast iron soil pipe and ﬁttings and the various joining methods demonstrate that cast iron affords a number of economic advantages. These advantages include performance, versatility, low cost installation, and product availability.

Cast Iron Installation

of building construction, including one and two story family homes, multiple units or apartment building, highrise structures such as hotels and ofﬁce buildings, and many commercial and industrial applications. The lead and oakum, neoprene compression gasket and hubless coupling can be used either individually or in combination in a given plumbing system in order to meet the needs of any speciﬁc condition. All three joining methods are available with a variety of pipe lengths and with a complete line of cast iron ﬁttings.

Low Cost Installation

Cast iron pipe and ﬁttings offer the advantages of

low-cost installation.

• The speed and efﬁciency with which the compression gasket joint and hubless coupling joint can be made.

• 10 foot pipe reduce the number of joints in a plumbing system.

• Reduced waste as compared to hub and spigot pipe.

• Smaller outside diameter ﬁts well within conventional 2x4 stud walls as compared to plastic pipe.

• Ease of fabricating in your shop.

Product Availability

Cast iron foundries are located in various sections

of the country so that orders can be ﬁlled on short notice. Contractors need not be concerned about supply or shortages since the manufacturing capacity is very adequate and readily obtainable from Charlotte Pipe.

Performance

The performance and durability of cast iron pipe and ﬁttings are superior to any other product used for sanitary and storm drain, waste, and vent piping. The choice is clear because service to the customer requires that performance constitutes the main reason for material selection, and in the matter of performance cast iron has no equal.

Versatility

Cast iron pipe and ﬁttings are the most versatile sanitary and storm drain, waste, and vent piping material on the market. It is available with a variety of joining methods so that it can be installed efﬁciently throughout the plumbing drainage system, both above and below the ﬂoor and underground. It is adaptable for use in all types

TYPES OF CAST IRON SOIL PIPE AND FITTINGS

Cast Iron Soil Pipe used in the United States is

classiﬁed into two major types – Hub and Spigot and

No Hub (Hubless).

Hub and Spigot pipe and ﬁttings have hubs into

which the spigot (plain end) of the pipe or ﬁtting is inserted. The joint is sealed with a rubber compression gasket or molten lead and oakum. Hub and Spigot pipe and ﬁttings are available in two classes of thickness. These are classiﬁed as Service (SV) and Extra Heavy (XH). Because the additional wall thickness is added to the outside diameter, Service (SV) and Extra Heavy

TYPES OF CAST IRON

SOIL PIPE

(XH) have different outside diameters and are not readily interchangeable. These two different types of pipe and ﬁttings can be connected using molten lead and oakum. Hub and Spigot pipe and ﬁttings are made in accordance with ASTM A 74 and are available in 2" through 15" sizes. Compression gaskets, lubricant, and assembly tools are readily available for ease of installation.

Hubless cast iron pipe and ﬁttings are simply pipe and ﬁttings manufactured without a hub, in accordance with CISPI 301, and are available in 11/2"

through 15" sizes. The method of joining hubless pipe and ﬁttings utilizes a shielded hubless coupling which consist of a neoprene rubber sleeve and a stainless steel shield that slips over the end of the pipe and ﬁttings and is tightened with a torque wrench.

Resistance to Abrasion

Cast iron pipe and ﬁttings are highly resistant to abrasion from sand, gravel, garbage disposal residue, dishwasher discharge, and debris being carried in suspension along the lower portion of the sewer or drain.

Uses

Cast iron soil pipe and ﬁttings are used primarily in building construction for sanitary and storm drain, waste and vent piping applications. The product is installed in residential construction, hospitals, schools, and commercial and industrial structures. For this reason, the pattern of cast iron soil pipe shipments and sales is directly related to the pattern of building activity.

In buildings, the principal assembly of this piping is installed within the partitions and serves the tub, lavatory, and water closet ﬁxtures. The main line in this assembly is the cast iron soil stack, which runs vertically from the building drain up through the structure and through the roof. Waste lines are connected to this main soil stack, and vent lines may also be tied in at a point above the highest ﬁxture. In some installations vent lines are connected to a separate vent stack, which acts as the main source of air to and from the roof.

The building or house drain, the lowest horizontal piping in the drainage system, receives the discharge from the soil, waste, and drainage pipes from within the building and conveys the discharge to the building sewer. The building or house sewer, in turn, conveys the discharge outside of the structure to the point prescribed

by the local plumbing code for joining of the city sewer, septic tank or other means of disposal.

Another use for cast iron soil pipe and ﬁttings in building construction is for storm drainage from roofs, yards, areaways and courtyards. It is used for collecting subsoil drains, which are placed around the foundation for connection into the storm drainage system, or into a sump. It is also used for roof leaders, particularly when the roof leaders are placed within the building, pipe space, or other areas. Extensive use is made of cast iron soil pipe for storm drainage on high-rise buildings where large setbacks accumulate substantial amounts of rainwater and snow. At present, cast iron soil pipe is used in high rise building structures for drain, waste, and vent and sewer purposes without concern for building height and is, in fact, the preferred material. There are large numbers of uses for cast iron soil pipe other than in building construction.

Requirements For A Safe and Durable Drain, Waste and Vent System

The satisfactory performance of a piping system used for drain, waste, vent and sewer plumbing requires that the material possess the following important characteristics:

• Strength and rigidity

• Durability exceeding expected life of building

• Quiet operation, resistant to noise transmission

• Noncombustible and does not contribute to the

spreading of ﬂames

• High crush strength and ability to withstand trafﬁc

and trench loads

• Ability to withstand temperature extremes

• High corrosion resistance

• Low coefﬁcient of expansion and contraction

• High abrasion resistance

• Leak-free joints that resist infiltration and ex-

ﬁltration

Cast Iron Soil Pipe and Fittings Meet or Exceed All These Requirements

Tests of cast iron soil pipe and ﬁttings for these properties reveal its superior characteristics as a material for drain, waste, vent, and sewer piping systems.

CORROSION RESISTANCE

Cast Iron Installation

Performance

Cast iron has, for hundreds of years, been the premier piping material throughout the world for drain, waste, and vent plumbing applications. Cast iron can be cast in the form of pipe or ﬁttings at low cost and has excellent strength properties. Unique corrosion resistance characteristics make it ideally suited for plumbing applications. Cast iron, because of the presence of free graphite, when exposed to corrosive conditions, leaves behind an insoluble layer of corrosion products that provide a barrier against additional corrosion.

Cast Iron is a generic term that identiﬁes a large family of ferrous alloys. Cast irons are primarily alloys of iron that contain more than 2% carbon and 1% or more of silicon. Cast irons can be cast into intricate shapes because of their excellent ﬂuidity. Because of the excellent properties obtainable with these low-cost engineering materials, cast irons ﬁnd wide application in environments that demand good corrosion resistance. Services in which cast irons are used for their excellent corrosion resistance include water, storm, and sanitary drain, waste, and vent applications.

The majority of soils throughout the United States are non-corrosive to cast iron. Water and gas utilities in the United States have cast iron distribution mains with continuous service records of more than 100 years.

Quality gray iron castings like the ones produced by Charlotte Pipe and Foundry have an abundance of free graphite present in their microstructure. When Charlotte products are exposed to corrosive agents, an insoluble layer of corrosion products is left behind, which provides a durable barrier against additional corrosion. This enhanced corrosion resistance is not provided by lower quality gray iron castings, because they have an insufﬁcient free graphite content, making them more prone to corrosion problems.

A small percentage of very special wastes may not be suitable for cast iron plumbing systems. Such waste streams can emanate from laboratories, some concentrated or undiluted carbonated soft drink sources, and sites where speciﬁc types of cleaning chemicals are discharged, particularly when the efﬂuent is undiluted. The very low pH wastes from such sources can corrode exposed cast iron. Charlotte Pipe and Foundry has developed a new “Hot Dip” coating process for cast iron pipe that offers signiﬁcant advantages over traditional bituminous coatings, including superior corrosion protection. Whether our coating or other coatings are

used, we have found that plumbers do not always apply protective coatings to the end of cut pipe and ﬁttings, thus leaving the system exposed to possibly corrosive elements.

The pH range for typical DWV systems is between 4.5 and 7. We suggest that the installer establish a uniform slope for horizontal drainage piping, but not less than permitted by local plumbing code and in compliance with good plumbing practices, to facilitate ﬂushing of the system. If operating conditions yield an acidity level of pH 4.3 or less for an extended time, we recommend dilution of the waste stream to raise the pH. If this is not possible, we suggest that the system designer’s look into a more suitable chemical waste system.

The National Bureau of Standards and the Cast Iron Pipe Research Association (now known as the Ductile Iron Pipe Research Association) have studied the underground corrosion of cast iron pipe for many years. As a result of these studies, a procedure has been developed for determining the need for any special corrosion protection. A simple and inexpensive method of providing such protection by means of polyethylene ﬁlm has been developed. The information contained in American National Standard A 21.5, American Society for Testing and Materials A 674, and American Water Works Association Speciﬁcation C 105 provides installation instructions and an appendix which details a ten point scale to determine if the soils are potentially corrosive to cast iron. Information on this standard is available from the Cast Iron Soil Pipe Institute and its member companies. It is also contained in the appendix to ASTM A 74 (Hub and Spigot Cast Iron Pipe and Fittings).

The co r r o sion o f metals u ndergrou nd is an electrochemical phenomenon of two main types: galvanic and electrolytic.

Galvanic corrosion is self-generating and occurs on the surface of a metal exposed to an electrolyte (such as moist, salt-laden soil). The action is similar to that occurring in a wet or dry cell battery. Differences in electrical potential between areas on the surface of the metal (pipe) in contact with such soil may occur, for a variety of reasons including the joining of different metals (iron and copper or brass). Potential differences may also be due to the characteristics of the soil in contact with the pipe surface: e.g. pH, soluble salt, oxygen and moisture content, temperature and the presence of certain bacteria. Any one of a combination of these

JOINING METHOD

factors may cause a small amount of electrical current to ﬂow through the soil between areas on the pipe or metal surface. Where this current discharges into the soil from such an area, metal is removed from the pipe surface and corrosion occurs.

Electrolytic corrosion occurs when direct current from outside sources enters and the leaves an underground metal structure such as pipe. At that point where current leaves the metal surface to return to its source through the soil, metal is removed and corrosion occurs.

Over 95 percent of the soil in the United States are non-corrosive to cast iron. Those few soils that are somewhat corrosive to cast iron include natural soils containing high concentration of decomposing organic matter (swamps, peat bogs, etc.) alkalis or salt (tidal marshes).

JOINING METHOD FOR HUB AND SPIGOT CAST IRON PIPE AND FITTINGS

The Compression Joint

The compression joint is the result of research and development to provide an efﬁcient, low cost method for joining hub and spigot cast iron pipe and ﬁttings. The joint is not unique in application to cast iron soil pipe, since similar compression type gaskets have been used in pressure pipe joints for years. The compression joint uses hub and spigot pipe and ﬁttings as does lead and oakum. The major difference is the one-piece neoprene rubber gasket.

When the spigot end of the pipe or ﬁtting is pulled or drawn into the gasketed hub, the joint is sealed by displacement and compression of the neoprene gasket. The resulting joint is leak free, and it absorbs vibration and can be deﬂected up to 5 degrees without leaking or failure.

Compression gaskets sold by Charlotte Pipe are precision molded of durable neoprene. Note that service gaskets must be used with service weight pipe and ﬁttings. Extra Heavy gaskets must be used with Extra Heavy pipe and ﬁttings.

Standard specification for rubber gaskets for joining cast iron soil pipe and ﬁttings is ASTM C 564. The properties of neoprene make it suitable for modern chemicals and acids, oil fats, greases. Additionally neoprene will not support combustion. ASTM C 564

gasket materials can be safely used up to 212° F. Joint deﬂection using a compression gasket has a maximum limit of up to 5 degrees. Maximum deﬂection should not exceed 1⁄2 inch per foot of pipe. This would allow 5 inches of deﬂection for a 10 foot piece of pipe and 21⁄2 inches for 5 foot pipe. Installation should initially be completed in a straight line and then deﬂected to the appropriate amount. This helps assure a good tight joint. For more than 5 degrees of deﬂection, ﬁttings should be used.

JOINING METHOD FOR HUB AND SPIGOT CAST IRON PIPE AND FITTINGS

The Lead and Oakum Joint (Caulked Joint)

Hub and spigot cast iron soil pipe and ﬁttings joints can be made with oakum ﬁber and molten lead, which are leak-free, strong, and root-proof. The water prooﬁng characteristics of oakum ﬁber have long been recognized by the plumbing trades, and when molten lead is poured over the oakum in cast iron soil pipe joint, it completely seals and locks the joint. This is due to the fact that the hot lead ﬁlls a groove in the bell end of the pipe or ﬁtting, ﬁrmly anchoring the lead in place after cooling. To make a caulked joint, the spigot end of a pipe or ﬁtting is placed inside the hub of another pipe or ﬁtting. Oakum is placed around the spigot in the hub using a yarning tool and then the oakum is packed to the proper depth using a packing tool. Molten lead is then poured into the joint making sure the lead is brought up near the top of the hub. After the lead has cooled sufﬁciently, it should be caulked with a caulking tool to form a solid lead insert. If horizontal joints are to be made, a joint runner must be used to retain the molten lead. Use customary safety precautions when handling molten lead.

neoprene gasket and a shield of stainless steel retaining clamps. Charlotte® hubless couplings are manufactured in accordance with CISPI 310, ASTM C 1277, and ASTM C 1540. Charlotte Super Duty couplings conform to ASTM C 1540. The great advantage of the system is that it permits joints to be made in limited access areas. The 300 series stainless steel, which is always used with hubless couplings, was selected because of its superior corrosion resistance. It is resistant to oxidation, warping and deformation, offers rigidity under tension with substantial tension strength, and yet provides sufﬁcient ﬂexibility. The shield is corrugated in order to grip the gasket sleeve and give maximum compression distribution to the joint. The stainless steel

Neoprene will not support combustion and can be safely used up 212° F. The neoprene sleeve is completely protected by a nonﬂammable stainless steel shield, and as a result a ﬁre rating is not required. Joint deﬂection using a shielded hubless coupling has a maximum limit of up to 5 degrees. Maximum deﬂection should not exceed 1⁄2 inch per foot of pipe. This would allow 5 inches of deﬂection for a 10 foot piece of pipe. Installation should initially be completed in a straight line and then deﬂect to appropriate amount.

HANDLING AND STORAGE OF

CAST IRON PIPE AND FITTINGS

HANDLING

Cast iron pipe and ﬁttings are customarily shipped by ﬂatbed truckloads. Cast iron will withstand the shock and stresses normally encountered in transit. The ﬁrst step upon arrival of the material at the destination should be a thorough inspection for damage that may have occurred in transit. The shipment will usually be accompanied with a Bill of Lading and a packing slip. The purpose of the Bill of Lading is the legal transfer of title for the material from the manufacturer to the carrier and from the carrier to the installer or wholesaler receiving the shipment. It is very important that any damage or shortage of products should be noted on the Bill of Lading to ensure that any claim for damage will be honored. The Bill of Lading

will reﬂect total pieces, bundles, or crates. The packing list will give speciﬁc description of each item shipped. It is necessary that the total pieces be checked and any discrepancies noted on the Bill of Lading before the carrier leaves the delivery destination. Notify Charlotte Pipe of the discrepancies as noted on the bill of lading as soon as possible. A copy of this document should be kept in a safe place if damage or shortages were noted. Charlotte Pipe ships its pipe pre-packaged in bundles and ﬁttings in boxes for easy unloading. Care should be taken when unloading the unit. Shipping tags are attached to each bundle and box identifying the contents of each unit. These tags should not be removed as they will be useful later in locating items as they are needed.
