FMC Technologies' Longsweep Swivel Joints have been the industry standard since their introduction in 1954. Now there is a new standard...the Longsweep 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. The TripleStep Swivel Joint is the ideal choice for your most demanding applications. Here’s what makes this swivel joint so special.
FMC Technologies is the leading manufacturer of Chiksan® swivel joint as well as many other flowline products. The standard TripleStep swivel joint (TSi), a primary choice by major service companies, is designed to overcome the limitations of conventional swivel joint. It is intended for today’s severe fracturing fluids, radical temperature extremes, and high flow rates. Swivel joint usually wears out in the ball race so it must be disassembled and returned to service frequently. FMC TripleStep design places more material under the male ball race – a location that computational flow dynamics analysis and field testing shows to be a high erosion area.
Features & 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 resistance 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.
- Longer life vs. competitive swivels joints confirmed by actual erosion testing witnessed by third party.
- Erosion is limited to elbow area not bearing race.
