Is 1500Bar
Brief Description of Hydraulic Bolt Tensioner
Ai Le Sen hydraulic bolt tensioners are designed and manufactured
to include a wear coated piston, maximum piston stroke indicator,
self-energising high pressure seals, dual quick connect couplings
for easy multiple tensioner connection and a user friendly
operation and maintenance procedure.
For
HTT imperial bolt tensioner range is designed for topside operation
in a wide variety of applications including pipeline flanges, heat
exchangers, pressure vessels, compressor covers, boiler feed pumps,
anchor bolts and many others. The range comprises of 26 imperial
size options ranging from ¾” to 4” thread size and all models are
suitable for working pressures up to 1500 bar. Each model of
hydraulic tensioning cylinder within the tensioner range can be
operated with a variety of threaded pullers and nut rotating
sockets ensuring that the maximum possible range of bolt sizes can
be accommodated using the minimum number of hydraulic cylinders.
Threaded pullers, bridges and nut rotating sockets are available as
individual components.
