ST Spring Return Hydraulic Bolt Tensioners
Made in the UK. The ST Spring Return design enables automatic piston retraction at the end of the tensioning sequence, ensuring the tools are prepared and ready for the next cycle. All models within the range have a stroke of 10mm and cover ranges from ¾” – 4 1 / 2 ” & M24 – M115 bolts, making them suitable for use on a vast range of flange sizes. They also offer both metric and imperial inserts as well as oversized versions for coated studs.
SS Subsea Tensioners
Made in the UK. The SS range of Subsea Tensioners has been designed and manufactured in the UK, to suit the demanding requirements of divers operating in harsh subsea environments. This range of tensioners bring a new generation of bolting with a quick release nut that has a unique positive locking system (patent pending). Comprising of 8 bolt tensioning tools, this series is capable of tensioning most subsea flanges. They are made from high strength stainless steel which greatly reduces maintenance work to a minimum after subsea use.
Air Tensioner Pumps
The air operated tensioner pump unit is designed and constructed to be failsafe, user friendly, lightweight and compact. The unit works on a simple but efficient principle, magnified through differential piston areas. A large piston drives a smaller hydraulic piston, which provides flow at high pressure. Although the pumps are compact, all the usable components are located within easy to reach places, with the large, simple to read gauges and equally large dial positioned clearly at the front of the pump. For durability, the frames are also made of stainless steel to protect against corrosion.
Electric Tensioner Pump
This new 1500 Bar electric pump has been specifically designed for tensioning applications with its lightweight and compact design for portability and ability to work in confined spaces. It incorporates the latest technology to offer the operator features and benefits which far surpass all other electric tensioner pumps available on the market today. The PE8 electric tensioner pump is designed to work in the harshest conditions, stay and to on the job longer, requiring less maintenance, thus reducing downtime and servicing costs. This electric tensioner pump unit is ideal for onsite construction and maintenance of wind turbines and equally ideal for all remote topside applications.
Hand Tensioner Pumps
The Hand Tensioner Pump is designed for those applications where there is no power available. These lightweight hand tensioner pumps are safe, low maintenance and durable meeting onsite bolt tensioning challenges. They are easy to operate and are supplied complete with a calibrated pressure gauge and quick release outlet coupling. The lightweight and portable design makes this the ideal pump for when you’re on the move.
Tensioner Hose Reels
We offer tensioner hoses & hose reels which are ideally suited but not limited to subsea use. Our hose reels come complete with a suitable high pressure coupler, brake mechanism and lock off facility. Typically each reel carries 210m of single line tensioner hose however custom length reels are also available contact us to discuss your specific requirement.
