TensionPro has developed a range of highly versatile and reliable hydraulic tensioners optimised for subsea applications in the offshore oil and gas industry. The new SUB series is ideal for tightening Norsok/SPO compact flanges, as well as all common sized ANSI, ASME and API flanges.
An ergonomic design features a one-piece body, anti-slip tool surface, contoured 'grip' reaction nuts and a high-vis finish. This makes it easy for divers to use the tools subsea. A 30mm piston stroke ensures each bolt tightening operation can be completed in one hit, without having to return the tool to the surface to reset the piston.
Customers can choose between solid or split reaction nut options to suit their application and budget. Both are interchangeable on the SUB series, providing complete flexibility. Split reaction nuts offer speed of use for some applications, while solid reaction nuts provide a fail-safe operation for applications with large or unknown bolt misalignment.
SUB's all stainless steel construction ensures long life performance and guarantees simple and efficient maintenance. Pressure tested and CE marked, the SUB series is supplied with detailed operating and safety manuals. Special one-off designs are available for any thread size, load and diameter requirements. Ancillary subsea equipment, including pumps, hose reels and downline can be supplied from stock.
Said Richard Outram, TensionPro Sales Director: "Our new range of SUB subsea tools offers the end user a quick, precise and reliable means of bolt tensioning in challenging conditions. The combination of features and reduced number of tools covering the maximum number of flange types makes it easy for divers to work quickly and achieve even flange and gasket compression, whilst saving time and ensuring accurate tightening of each bolted joint."
