Torque Control Systems

Swivel Rental’s Torque Control Systems are used in the makeup of casing, tubing, drill pipe, downhole motors and accessories, etc. Swivel Rental’s Torque Systems can be installed and run with hydraulic, pneumatic, or manual tongs in the field, as well as, "bucking units" in plant applications.

The CT 3000LT features high resolution graphics with two 16 bit processors and a choice or four makeup programs. All PC hardware options are available in a unit that can be built to customer hardware specifications. Several "add-on" modules such as internal pressure testing, and accessories for hazardous area operations are available. Software is "User Friendly" allowing shortened training for field technician.

GRIT FACE™ Dies: For low to high torque applications on fiberglass and corrosion resistant alloy (stainless steel) tubulars where the use of steel dies is prohibited as well as on carbon steel tubulars where reduced marking is desired.

GRIT FACE™, insert system is not totally non-marking, the depth of the imprint left on the tubular after the application of very heavy loads is significantly less than the depth of slip marks left by conventional inserts.

GRIT FACE™, insert from the normal pipe mill surface imperfections. It is our belief these results are considerably better than competitive systems as they are shallower, are in a random pattern which reduces stress risers in the tubulars, and they do not contaminate the CRA tubing with steel, iron, or carbon. As an additional benefit, our large amounts of foreign materials which are often found on the exterior of tubulars when removed from wells.

GRIT FACE™ inserts do not leave aligned “slip marks” which are known to reduce mechanical strength.

GRIT FACE™, This technology, field proven in tong applications, now provides the indus-try with handling tool inserts designed to protect CRA tubing and casing strings from the hazards associated with the use of conventional steel toothed inserts. A combination of exotic materials used in these new inserts protect CRA tubulars from contamination associated with con-ventional steel inserts.


Grip Grip


Wrap Around Dies are available in three types:

Fine Toothed Steel Dies: For low to ultra high torque applications on carbon steel tubulars including tubing, casing, and drill pipe.

Smooth Faced Aluminum Dies: For low to moderate torque applications on fiberglass and corrosion resistant alloy (stainless steel) tubulars.

GRIT FACE™ Dies: For low to high torque applications on fiberglass and corrosion resistant alloy (stainless steel) tubulars where the use of steel dies is prohibited as well as on carbon steel tubulars where reduced marking is desired.

Valuable: Used to protect CRA and expandables tubulars from damage and corrosion.

Innovative: Continuous research and development keeps pace with advancing technology in the field.

Universal: The ONLY dies and inserts that are adapted to allow any handling tool to be used with expandables or CRA tubulars in compliance with API, ISO and NACE recommendations.

Field tested:
• Used on tubulars from 1.06” to 24”.
• Heaviest string run to date weighs in excess of 400 tons.
• More than a decade of proven experience.

GRIT FACE™ die and insert coating system combines the use of extremely hard granular particles, high strength corrosion resistant brazing materials and application processes which insure optimum dimensional control.

Tungsten Carbide granular particles are graded by size and shape to provide uniform granules with desired geometry. Different particle sizes are selected based upon application. Coatings on smooth surface dies use larger particles than the coatings applied to dies which have machined teeth. Coating thicknesses for small particles are approximately 0.010". Thicknesses for large particle coatings is approximately 0.025" thick.

Use of grade C-4 tungsten carbide refractory material controls the chemistry of the granular particles to prevent iron contamination. The Tungsten Carbide particles are metallurgically bonded to the die substrate using a high strength Nickel/Chrome brazing compound containing 83% nickel, 6.8% Chromium, 4.2% Silicon and 3% Boron. The remaining 3% balance of materials consists of a variety of trace elements including a small percentage of iron. It is important to note these materials are alloyed together at extremely high temperatures so there is no free iron available to contaminate CRA tubulars.

The Tungsten Carbide granular particles and brazing material are applied in controlled quantities using proprietary dispersion processes which align the particles and insure uniform distribution of materials in a single layer. The quantities of materials used insure the particles are securely fixed to the substrate but left with enough exposed surface to precisely grip oilfield tubulars.

Brazing of the components takes place at 1800 degrees Fahrenheit in a controlled atmosphere furnace where temperatures and times are precisely controlled. Mechanical properties of the die or insert substrate are controlled using a combination of pre and post-brazing heat treatment processes.
