FMC Technologies Chiksan® TripleStep Swivel Joint
The TripleStep Swivel Joint designed to overcome the limitations of conventional swivel joints, the TripleStep swivel joint easily handles today’s severe fracturing fluids, radical temperature extremes, and high flow rates
Features and Benefits
- Flexibility in line layout similar to original Chiksan® swivel joints
- Patented TripleStep race design
- Thicker wall section under the male ball race minimizes erosion in this area
- “Stepped” ball race design lowers the stress in the ball race and creates stronger bearing race both in tensile and bending load applications
- Use of more balls to carry the load. More uniform ball load eliminates brinneling of ball race under hydrostatic test pressure.
- Less torque under pressure than competitive brands.
- Stronger & tougher material improves erosion resistant by 50%-200% due to the thicker wall section under the ball race of TripleStep design.
- Superior grease and environmental seals virtually eliminate swivel joint component scrapping due to ball race corrosion.
- Erosion is limited to elbow area not bearing race.
Chiksan® Swivel Joints are metal are metal pipe fittings with integral ball-bearing swivels. These rugged fittings come in 3/8- to 12-inch sizes and can handle cold working pressures up to 20,000 psi. Chiksan swivel joints are available for sour gas services at cold working pressures up to 15,000 psi. End connections are threaded, integral Weco® wing union, beveled for welding or flanged. Sour gas swivel joints have Weco wing union end connections.
Features and Benefits
- Pressure-tight seals protect bearings from line fluidChiksan swivel joints come standard equipped with nitrile packing and bonded, brass anti-extrusion ring.
- Bearings key to rotation, strengthTo assure long, dependable operation, Chiksan ball bearings are matched to loading and service conditions with two rows of bearings in each swivel and flame-hardened ball races.
- Smooth, round bore minimizes flow restrictionsChiksan swivel joints have smooth, round bores to minimize turbulence and keep pressure drop low.
- Simple maintenanceOnly occasional light greasing with a small, hand-held grease gun is required to keep Chiksan swivel joints on the job.

MC Technologies Weco® Integral Fittings and Pup Joints
Now there’s a new Lightweight Fittings family that is ideal for handling a complete range of well servicing fluids at cold working pressures to 20,000 psi. Available in 1- to 4-inch sizes, FMC fittings feature high-quality forged construction with integral Weco wing union end connections for a high-strength, high-integrity connection every time. Tees, elbows, crosses, wyes, and laterals can be combined to suit virtually any installation. Like other FMC flowline products, FMC’s Integral Fittings come with full material traceability and can be supplied with Charpy impact values.
Plug Valve Manifolds
FMC Integral Fittings can be used in combination with FMC Plug Valves to create manifolds for choke-and-kill, well testing, squeeze, flow back, and cementing applications. Unlimited manifold designs using FMC’s advanced ULT and world proven DR Plug Valves can be easily constructed. Because FMC’s new line of integral fittings are lighter and smaller, you save valuable weight and space regardless of manifold design.
Weco ULT and DR plug valves are premium, quarter-turn valves designed for a wide range of standard and sour gas drilling, production, and well-servicing applications. These rugged valves are offered in single and dual-body designs in pressures to 20,000 psi. They range in size from 1 to 4-inches and come with threaded, Weco wing union, flanged, and clamp hub ends. Consult factory for configurations. Like all pressure containing products, Weco plug valves require special handling.
ULT Plug Valves-Benefits:
- Ultimate Seal-ability
The key to the ULT plug valve’s unprecedented seal integrity is its proprietary floating plug and dual-seal design. When the valve is closed, the dual segment seal provides a redundant seal on the downstream side of the valve.
- Ultimate Valve Body Life
When a ULT plug valve is closed, the only available flow path is between the seal segment and plug interface. This flow path eliminates body erosion and limits any potential wear to replaceable components.
- Ultimate Seal Life
The dual-seal design of the ULT plug valve, by forcing flow between the plug and segment interface, eliminates problem which is extrusion damage to the upstream and downstream segment seals.
- Ultimate Life Cycle Cost Savings
Superior sealability, increased life of valve body, and elimination of premature seal damage result in significant savings in life cycle costs of the ULT plug valve over traditional plug valves.
