Stu Series Subsea Bolt Tensioner Maximum Working Pressure 1500Bar
Product Brief
The Stu series of subsea bolt tensioners are designed and manufactured to meet the increasing demands of submersible operations in harsh subsea environments. This series of bolt tensioners consists of two parts, one is a threaded tensioner for quick installation and release, and the other is an integrated hydraulic cylinder and base. The piston travel has 20-30 mm to reduce the number of re-stretching operations. The STU series subsea bolt tensioner is a reliable and effective solution for tensioning subsea bolts. One size cylinder can be used with several different sizes of thread pullers. Thread stretching heads can also be ordered separately according to demand, which is highly versatile and more cost-effective.
Features of Stu
1. Single acting design spring return
2. Simple design for easy subsea operation
3. Made of high-quality anti-corrosion materials, increased anti-corrosion performance.
4. Maximum stroke indicator line to warn operator not to overextend the piston.
5. Two quick oil inlets for easy use of tools in tandem.
6. Designed to fit most sizes of ANSI and API flanges as well as some compact flanges.
7. Replaceable quick pull heads for handling other bolt sizes
8. Subsea bolt tensioners can be customized
