Petol U8184 Hydra-Tork Description

The U8184 Petol Hydra-Tork unit was designed for making up and breaking out downhole
tools. It is rated for operation on 4” to 14” diameters with a maximum working load of up to
95,000 ft-lbs depending upon diameter. See the table on the following page for specific
torque ratings. The unit may be operated in any position (horizontal or inclined) and is
totally portable.

The Petol Drill Pipe Tongs are adjusted to the different diameters within their range by
adjusting the chain screw nut for fine adjustment and by adding or removing sections of
chain for the coarse adjustment.

The U8184 also offers the following features:

The tong cylinder and backup tong are mounted on separate tracks for switching from
make up to break out. The tong slides utilize lead screws for adjusting the position of the
tongs. The lead screws are powered by a hydraulic motor. The tongs are raised and
lowered by an auxiliary lift handle (included).

Two adjustable vee-saddles mounted on the hydra-tork base for support. The vee-saddles
are also mounted on a track for easy adjustment.

The unit can be operated with any commercially available hydraulic power unit capable
of delivering 5000 psi pressure.

Safe Practices and Procedures

Responsibility

“It is the responsibility of the employer to train the employee in the proper selection and
usage of tools, chains, etc., and to ensure that they are selected and used in that manner. In
many instances, injury results because it is assumed that anybody knows how to use common
hand tools. Observations and the record show that this is not the case. A part of every job
instruction program should therefore be detailed training in the proper use of hand tools (and
of all other special tools and equipment needed to accomplish the job).” - (Source: National
Safety Council)

“Employers are responsible for the safe condition of tools and equipment used by employees,
including tools and equipment which may be furnished by employees.” - (Source: OSHA

1910.242A)

Replacement Parts

Use only PETOL & TITAN replacement parts - no other parts are of comparable strength,
quality and interchangeability.

Safety

While we pride ourselves on the quality and dependability we build into GEARENCH tools
and products, we caution users that it is only prudent to know and follow the simple rules of
safety when using our products, or anyone else’s.

Always follow safe practices and procedures in accordance with the recommendations of
OSHA, The National Safety Council (NSC), The Hand Tools Institute (HTI), The National
Association of Chain Manufacturers (NACM), The International Association of Drilling
Contractors (IADC), Etc. All applicable Governmental rules, regulations or restrictions, now
in effect or which may be promulgated, take precedence over the suggestions in this
publication. The information in this publication is designed to supplement standard safe
practices and procedures, not in lieu of, or replacement thereof.

7

Safe Practices

Failure to observe one or more of the following five safe practices accounts for most hand
and powered tool accidents:

1. ALWAYS WEAR SAFETY GOGGLES TO PROTECT EYES

2. SELECT THE RIGHT TOOL FOR THE JOB

3. KEEP TOOLS IN GOOD CONDITION

4. USE TOOLS CORRECTLY

5. KEEP TOOLS IN A SAFE PLACE

Persons in any area where hand or powered tools are being used must always wear safety
goggles.

Never strike wrenches and tools with hammers or other objects.

All tools should be kept clean, inspected on a regular basis, and replaced when they show
signs of wear.

Be especially careful not to place yourself in a position that could result in bodily injury in
the event of a failure. See diagram on page 20.

READ SAFE PRACTICES AND PROCEDURES MANUAL, CATALOG
INFORMATION, AND PRODUCT LABELING PRIOR TO OPERATION.

IT IS THE RESPONSIBILITY OF THE PURCHASERS OF GEARENCH PRODUCTS TO
CONVEY THE INFORMATION IN THIS PUBLICATION AND ANY OTHER
INFORMATION RELATING TO THE INDIVIDUAL PRODUCT, THROUGH THE
CHANNELS OF DISTRIBUTION, DOWN TO AND INCLUDING THE INDIVIDUAL
USING THE PRODUCT

NOTE

:

In view of the fact that the actual use determines whether safety requirements have
been met, the ultimate responsibility to comply rests with the end user.

Tong and Vise Chain Inspection

The service life of leaf chains can be altered by a variety of adverse operating conditions.
The following information discusses the most important of these conditions for consideration
when operating or scheduling replacement of leaf chain systems.

Overloading / Shock Loads / Side Loading

Attempting to “inch loads which are beyond the rated capacity of the tool.

Striking the tool with a hammer or other object while force is being exerted in an attempt to
loosen a “frozen” joint.

Side pull can be caused by pulling or pushing on the tong in a direction that is not along a
perpendicular plane, unleveled mounting of the tong or vise, inadequate support of the part
being broken out, and improper seating of the part being broken out in the tong or vise.
Improper seating will occur when the diameter of the part is not consistent within the width
of the tong or vise jaw.

Environmental Conditions

Wrench chains operate in widely varying environments, from wet outdoor conditions to
mildly or highly corrosive industrial atmospheres. They can also be exposed to abrasives
such as sand or grit.

The possible effects include:

Moisture - Corrosion and rust reduce chain strength by causing pitting and cracking.

Temperature - Very cold temperatures reduce chain strength by embrittlement.

Chemical Solutions or Vapors - Corrosive attack of the chain components’ grain structure
and/or the mechanical connections between the chain components (crevice corrosion)
may occur. Cracking often is microscopic. Propagation to complete failure can be
eventual or sudden.

Abrasives - Accelerated wearing and scoring of the articulating chain members (pins and
plates) may occur, with a corresponding reduction in chain strength. Due to
inaccessibility of the bearing surfaces (pin surfaces and plate apertures), wear and scoring
are not readily noticeable.

9

These conditions, when coupled with normal chain wear and inherent residual stress
(normally in the chain as constructed); can result in environmentally assisted failure. It is
impossible to predict chain life under complex conditions, as the degree of hostility and its
effects are dependent on many variables such as temperature, time of exposure, concentration
of corrosive atmosphere or medium, degree of abrasive wear, etc. Establishing the degree
and frequency of unpredictable dynamic loading is also difficult.

Normal Life Expectancy

A leaf chain’s normal life expectancy can be expressed as a maximum percent of elongation.
This is generally between 2% and 3% of pitch. As the chain flexes back and forth, the
bearing joints (pins and inside link plates) gradually wear from articulation. As with all steel
bearing surfaces, the precision hardened steel joints of leaf chain require a constant film of
oil between mating parts to prevent wear and to resist corrosion.

Lubrication

One of the most important but often overlooked factors is adequate lubrication. In addition
to reducing internal friction, maintaining a film of oil on all chain surfaces will inhibit rusting
and corrosion, this is important as corrosion of highly stressed, hardened steel chain
components can cause a major reduction in the load capacity of leaf chain and result in link
plate cracking.
Protection from corrosion is important in storage as well as in service. The factory lubricant
applied to PETOL CHAIN is a “Fingerprint Neutralizing Water-Displacing Corrosion
Preventative”. This is an excellent rust and corrosion inhibitor for chains in storage. When
installing these chains new, do not attempt to steam clean or degrease this lubricant. A grade
of SAE 30 or 40 weight, non-detergent motor oil should be used as supplemental lubricant
and a film of this oil should be maintained on all surfaces and internal bearing joints. Also,
do not attempt to paint new chains. Though painting may help inhibit corrosion, it will seal
off critical clearances and restricts oil from reaching the pin surfaces where it is needed for
good joint lubrication.

When operating in dusty environments, lubricated chains will accumulate a paste-like
buildup of grime. At periodic intervals, this buildup should be removed by cleaning and the
chain should be immediately re-lubricated. Do not use caustic or acid type cleaners; use a
stiff brush and a certified safe petroleum base solvent.

Periodic Inspection List for Petol Special Chain

1. PRIOR TO EACH USE, LEAF CHAIN AND TOOLS SHOULD BE
INSPECTED FOR SERVICEABILITY AND LUBRICATION.

2. USE ONLY PETOL AND TITAN REPLACEMENT PARTS - NO OTHER

PARTS ARE OF COMPARABLE STRENGTH, QUALITY, AND

INTERCHANGEABILITY.

11

12 13

Safety Precautions

1. Always wear safety goggles to protect eyes.

2. Select the right tool for the job.

3. Keep tools in good condition.

4. Use tools correctly.

5. Keep tools in a safe place.

6. Wear protective clothing, gloves and safety shoes as appropriate.

7. Use lengths of assembled chain. Do not build lengths from individual components.

8. Do not attempt to rework damaged chain by replacing only the components obviously
faulty. The entire chain may be compromised and should be discarded.

9. Never electroplate assembled leaf chains or components. Plating will result in failure
from hydrogen embrittlement.

10. Do not weld any chain or component. Welding spatter should never be allowed to
come into contact with chain or components.

11. Leaf chains are manufactured exclusively from heat-treated steels and therefore must
not be annealed. If heating a chain with a cutting torch is absolutely necessary for
removal, the chain should not be reused.

12. Inspect chains frequently and regularly for link plate cracking, pin turning, pin
protrusion and corrosion.

13. Use only PETOL & TITAN replacement parts to ensure proper strength.

Installation

Location

The Petol Hydra-Tork Unit should be located in an area with adequate room to work the
downhole tools. The unit may be located indoors or outdoors upon solid ground or a finished
shop floor. No special foundation is required.

Setup

Locate the hydraulic power unit in a convenient location and connect the hoses to the
hydraulic cylinder.

Operation

Controls

Use a hydraulic pressure gauge to indicate the current system pressure in psi. The torque
produced by the Petol Drill Pipe Tongs is dependent on the hydraulic pressure and the
diameter. A conversion chart for equating the hydraulic pressure in psi to the torque output
in ft-lbs follows:

WARNING: Never operate the tong with a pressure higher than required to

perform the make up or break out operation. Operation at excessive pressure
may damage the downhole tool and/or injure personnel.

14

Torque -Pressure Conversion Chart

To use chart:
Draw a line from the diameter of the pipe through the desired torque. Read the hydraulic pressure from the
right hand column.

Loading

To load the downhole tool in the unit, adjust the vee-saddles to support the tool. Set the tool
into the unit. Position the tongs for make up or break out as needed and set the tongs onto
the tool using the tong lift handles as shown in the diagram below. Adjust the tongs as
described and latch the tong chains.

CAUTION: The vee-saddles must be used to support the tool while torquing.

Tong Adjustment

Add or remove chain sections as needed using the splice bolts in the chains. Push on the top
of the jaw to fully compress the spring inside the jaw. Adjust the chain screw nut so that the
chain is as tight as possible and fit into the lugs in the jaw.

Breaking Out

Load the tool and adjust the tongs as described above. Fully ratchet the tong by extending
the cylinder. Set the system pressure to a minimum. Retract the cylinder. When the tong
stops, begin increasing the system pressure. Keep increasing the system pressure until the

connection is broken loose or the working load of the tong is reached. Do not exceed the

rating of the tong. Consult with GEARENCH as needed for help with the toughest
break out jobs. After the initial break out, ratchet the tong fully and then alternately extend

and retract the cylinder until the connection is fully loosened.

Making Up

Load the tool and adjust the tong and vise as described above. Make up the connection hand
tight using TITAN chain tongs. Preset the system pressure to obtain the desired torque if
possible. Retract the cylinder. If the cylinder fully retracts without stalling, cycle the tong
(extend / retract). Continue until the cylinder stalls or until the desired pressure is obtained.

19

Warning: Do not stand in line with the tongs or chains during operation.
