Double Acting 1500 Bar Hydraulic Stud Tensioners St Series Subsea Bolt Tensioner

ApplicationWhy You Need Hydraulic Tensioner?The bolt tensioner uses pure tension to directly elongate the bolt, without torsion shear and lateral force, and no frictional damage to the contact surface. It is the best method to accurately control the bolt pre-tightening force. Compared with hydraulic torque wrenches, bolt tensioners have the advantages of rapid response and accuracy, no torsional stress, no frictional damage, and simultaneous pre-tightening of multiple bolts. The bolt tensioner can be used singly, or multiple tensioners can be used in parallel, which can not only improve efficiency, but also ensure the uniformity of the force of multiple bolts. When the bolt center distance is small and the radial size is restricted, a two-stage structure can also be adopted, and the axial size is sacrificed to ensure the radial size. In the case of the same outer diameter, the effective area of the piston is doubled, and the force generated is doubled.The disadvantage is that it needs enough screw elongation, which will be very limited in the case of narrow axial space.  Product Description1. ST Series Bolt Tensioners are designed for critical fastening applications in wind, steam and gas turbines.2. Max tool pressure - 21,750 psi (1,500 bar working pressure).3. Covers bolt ranges from 3/4" - 4" & M24 - M100.4. Automatic spring return piston retraction.5. Dual Ports for Multi-tool use.6. Our spring return feature provides automatic piston retraction when pressure is released. This saves the time and effort required to reseat the piston after every stroke, giving you more energy to finish the job.Product ParametersRelated ProductsPackaging & ShippingPacking: 1pc/wooden case, the air source is packed separately in paper carton with foam.Shipping: according to order quantity, it's shipped by express, by sea, by land transportant, by air, or by train.CertificationsCompany ProfileBaier Hydraulic Power (Wuhan) Co.
