Petol SCT3672 Surgrip Casing Tong Description
The SCT3672 Petol Surgrip Casing Tong was designed for making up and breaking out large
diameter casing. It is rated for operation on 18" to 38" diameters.
The tong is adjusted by exchanging belts to work different nominal sizes of casing.
The SCT3672 offers the following features:
A high strength aramid fiber belt with polyurethane covering to grip the pipe and
reduce the weight dramatically as compared to chain or lug jaws.
The tong is designed such that in case of an overload, the belt would fracture and
extend. The tong will stay connected to the casing and no fragments would be
expelled from the tong.
A hanger attached to the tong handle to suspend the tong during operation with
multiple mounting holes to achieve a proper balance point.

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 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.
Safe Practices
(Source: The National Safety Council)
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
4
Page 7
Safety Goggles must always be worn by persons in any area where hand and powered tools
are being used.
Never apply excess leverage to a wrench or tool by means of a "Cheater Bar". 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. Brace yourself firmly and pull rather than push when wrenching. (If
necessary to push, do so with the flat of the hand rather than gripping around the wrench.)
Never stand under or near loads being hoisted off the ground.
READ SAFE PRACTICES AND PROCEDURES MANUAL, CATALOG INFORMATION
AND PRODUCT LABELING PRIOR TO OPERATION.
Spinning and drill pipe chain, cathead chain, and the PETOL Connecting Link attachment
are designed for the specific purpose for which the name indicates. Chains and attachments
that are to be used for any other purpose should be selected in accordance with the
recommendations of ASTM, NACM, Rigger's Handbook, and the commercial chain
manufacturer's technical manuals.

Responsibility of Distributors
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 Inspection
It is recommended that the tong be visually inspected on a daily basis for signs of damaged
components. The belt should be visually inspected on a daily basis for indications of
exposed cords or fractured cords. Belts with more than 6 exposed cords should be
immediately removed from service. Belts with any single exposed cord reduced to 2/3 (67%)
or less of the initial fiber cross-sectional area should be immediately removed from service.
A belt with any cord which protrudes through the polyurethane covering, which indicates a
fractured cord, should be removed from service immediately. Cord separation is allowable
provided the fibers are not exposed beyond the limits stated above. The hanger bolts should
be inspected on a daily basis.
It is recommended that the tong handle and jaw be removed and magnetic particle inspected,
at a minimum, on an annual basis for indications of cracking. Local operational procedures
may require more frequent inspection. Please refer to the appropriate section for inspection
criteria and allowable repair procedures.
Overloading / Shock Loads / Side Loading
Damage to the tong is possible if the following conditions are present. Users are cautioned
to be aware that these practices could result in premature breaking of the tong.
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 on the belt. 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 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 OD of the part is not consistent within the width
of the tong or vise jaw.

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 only PETOL & TITAN replacement parts to ensure proper strength.

Operation
The typical application of one Surgrip Casing Tong is shown in the figure below. Normally
an additional tong is used as a backup. The backup tong is not shown for clarity. The tong
will exert torque in the direction shown. The tong will ratchet when moved in a direction
opposite to the line pull. Ratcheting is used when the tong must be pulled more than once to
completely makeup or breakout the connection.
Suspension
The tong should be suspended by the attached hanger. Use the appropriate hole in the hanger
to obtain the best possible balance of the tong. Always use a suspension line of adequate
capacity to safely hold up the tong during operation.

Non-Destructive Evaluation
The figure below indicates the critical areas of the tong handle. A critical area is defined as
an area in which no unrepaired crack indications are permitted and in which no major weld
repairs are permitted. A weld repair shall be considered minor when the depth of the cavity
does not exceed 30% of the actual wall thickness or 1 inch, whichever is smaller, or when the
extent of the cavity does not exceed approximately 10 square inches. Major weld repairs
must be performed by Gearench or an approved repair center using appropriate procedures
followed by full heat treatment and load testing
meet these criteria.

Weld Repairs
Scope:
This procedure is to be followed for minor repairs of crack indications in heat treated alloy
steels. A weld repair shall be considered minor when the depth of the cavity does not exceed
30% of the actual wall thickness or 1 inch, whichever is smaller, or when the extent of the
cavity does not exceed approximately 10 square inches. Major weld repairs must be
performed by Gearench or an approved repair center using appropriate procedures followed
by full heat treatment and load testing
Application:
This procedure applies to steel castings, forgings and, wrought with carbon content between
0.25% and 0.31%.
Weld preparation:
The crack indication is to be removed by carbon arc gouging, grinding, or machining until all
indication is removed. Magnetic particle inspection shall be used to verify that the crack
indication has been removed.
Filler material and process:
Repairs shall be made with the FCAW process with a filler material of class E71T-1 or
equivalent with CO2 shielding gas by a qualified welder.
Preheat:
Preheat the weld area to 400°F minimum.
Interpass temperature:
The interpass temperature to be 850°F maximum. All weld slag to be removed prior to
application of additional layers.
Post weld heat treatment:
