Hydraulic bolt tensioner SBT series

The SBT imperial range of hydraulic bolt tensioners, offers all of the features and benefits of our standard STS range, but with the added feature of spring assisted return hydraulic pistons. Designed primarily for topside operation, this additional spring return piston feature will reduce bolt tensioning cycle times considerably, as the tensioner pistons will automatically start to retract, after the hydraulic pressure is released. The range currently comprises of 22 models, suitable for standard size bolts from 1 ¼” to 4” diameter. The versatility of the SBT bolt tensioner range, is identical to our standard STS range, with a variety of interchangeable threaded pullers and nut rotating sockets available, either as bolt size conversion kits or individual parts. All SBT bolt tensioners are designed and manufactured with a wear coated piston, maximum stroke indicator, self energising high pressure seals, dual quick connect couplers, for easy multiple tensioner hook up and operate at pressures up to 1500 Bar maximum. Capacities from 457 to 2649 kN Bolt sizes from 1¼" to 4" diameter Maximum working pressure 1500 bar Single acting design with spring assisted return High grade alloy steel construction Nitrocarburised piston Maximum piston stroke indicator Dual quick connect couplings for easy connection Designed to fit most sizes of ANSI and API flanges and some Compact flanges Interchangeable accessories to cover multiple stud bolt sizes using same tensioner Customised and special design tensioners are available on request
