i.Training for Ameron Dualoy® Piping Systems
1.Installation training for Ameron Dualoy 3000/L piping systems, including secondarily contained systems and Dualoy 3000/LCX, shall be done by an Ameron employee, sales representatve or distributor.
2.Training shall, at minimum, consist of a thorough review of the installation instructions (Bulletins, 7501, 8702 and/or 9903) as applicable for the systems on which the installer is to be certified. It is recommended that an installation video, (such as “Dualoy 3000/LCX Installation”) be used during the training session. Also recommended is an examination of the installation tools, a demonstration of the joint preparation and bonding and, if possible, a “handson” execution of the installation procedures for a sample connection.
3.Upon completion of the training, each individual being trained shall complete the written examination for the systems on which they are to receive qualification.
4.The examinations will be signed by the trainee and the instructor and forwarded to Ameron for grading and registering of the individual as a “Certified Installer.”
5.Ameron will issue a training certificate with the individual identified and will include their name on a registration list. Wallet-sized certificates and hard hat stickers may also be provided. Training certificates are valid for three years.

1 Introduction
Dualoy 3000/LCX pipe and fittings are manufactured from thermosetting epoxy resins reinforced with high tensile strength fiberglass filaments. The pipe is produced by filament winding. The pipe incorporates a resin-rich inner liner that is resilient and holiday-free and a resin-rich outer coating that protects the structural wall from UV degradation during storage and installation. The structural wall strength of Dualoy 3000/LCX pipe is unsurpassed in the fiberglass pipe industry. Fittings are manufactured by filamentwinding or compression molding.
Dualoy 3000/LCX pipe and fittings are electrically nonconductive and never require cathodic protection or sacrificial anodes. Installed systems are immune to external corrosion from stray-current electrolysis and cathodic interference. They are unaffected by alkaline or acidic soil conditions.
The containment on the pipe is coaxial and an integral part of the piping. The containment over the fittings is made by applying matched clamshell fittings over the primary fitting, connecting the pipe containment jackets.
The primary piping and containment fittings are joined using the same, strong, reliable, bonded joint as in Dualoy 3000/L single wall piping.
Dualoy 3000/L single-wall piping systems
Detailed installation instructions for Dualoy 3000/L single-wall piping may be found in Ameron Bulletin 7501 (FP104) available from Ameron Fiberglass Pipe Group or your Ameron distributor.

Dualoy 3000/LCX is Listed in the United States with Underwriters Laboratories for nonmetallic underground piping for motor vehicle fuels (MV), concentrated fuels (CF), high blend fuels (HB) and aviation and marine fuels (AM). It is also Listed with Underwriters Laboratories Canada (ULC)for the same fuel categories. It can be used for integral primary/secondary (PS) services where both layers are combined into one unit under UL File No. MH 15596. The ULC File No. is CMH 715.
3 Inspection, handling and storage
Inspection
Careful inspection of the outer (secondary) layer of pipe is especially important on coaxial containment installations. Since damage to the primary is not visible once the pipe is installed, it is essential to check the outer pipe jacket for damage. Testing and experience has proven that no damage will occur to the primary pipe without an indication of damage on the outer jacket.
Upon receipt at the job site, inspect the pipe fully. Locate, cut out, repair or replace damaged pipe. Impact damage is usually recognizable as rounded pale areas just under the surface or as deep gouges, scratches or cracks. Remove end protectors to inspect tapers for damage and then replace protectors.
Handling
Dualoy 3000/LCX has higher impact resistance than single-wall pipe, however, fiberglass pipe is susceptible to damage if handled improperly. Adhere to the following recommendations when handling:
•Do not transport pipe without proper protection against impact.
•Truck pipe racks should be padded with carpeting or like material to prevent damage.
•Tie the pipe down during transport to prevent it from bouncing on the racks.
•Do not use chains to tie down the pipe on a truck: Use nylon straps or hemp rope.
•Do not drop the pipe from truck bed when stringing: Lay the pipe down by hand.
•Pipe loads that are properly separated and supported can be unloaded by padded forklifts.
Storage
Dualoy 3000/LCX pipe incorporates a resin-rich outer coating which provides outstanding UV resistance. Pipe stored out-of-doors for extended periods may assume a chalky appearance. However, this change in appearance is superficial and does not affect the pipe’s performance. Protect stored pipe from impact damage by stacking on padded racks.

4 Materials
When using pneumatic tools, the air supply must be dry and oil-free as moisture or oil on bonding surfaces will interfere with the adhesive.
Pipe
Manufacturer tallies pipe on the basis of overall length. Allow for cutting losses and wastage when ordering.
Fittings
Contained fitting assemblies are sold in the following boxed quantities.

Note: Fasteners are included with fittings..
Adhesive
Ameron supplies PSX™•20 and PSX™•34 adhesives. The PSX™•20 and PSX™•34 adhesives are polysiloxane-modified epoxy formulations. They are designed to make permanent bonds in primary or containment systems transferring MV, CF, HB or A&M fuels. They are also approved for use with MTBE fluids. Each is supplied as a two-part system consisting of a resin and a hardener.
Each adhesive kit contains:
• |
Resin |
• |
Detailed usage instructions |
• |
Hardener |
• |
Emery paper |
• |
Mixing stick |
• |
Gloves |
• |
Spatula and brush |
• |
Paper towels |
Refer to the layout drawings to estimate the number of adhesive kits required. Include bonds for all fittings, elbows, tees, reducers, adapters and couplings plus a waste factor. Short pot life at higher temperatures may not allow as many bonds to be made as indicated in the table: allow a greater waste factor at higher temperatures. For further information refer to the adhesive product data sheet.
