machine Do bolts stretch when torqued? As you tighten a bolt, it will stretch and generate a clamp load.
The key to proper tightening of a fastener is to torque it until
just slightly less than the bolt's elastic limit. A bolt will
stretch slightly as it is tightened. If you tighten the bolt too
much, it will stretch beyond its elastic limit.
Features a. Black-oxide outside b. Special finish for service up to 240℃ working condition c. Optional materials, like stainless steel,nickel plated,chrome plated for corrosion resistance. d. High pressure unidirectional or bidirectional joint e. Max. pressure: 800 bar f. Easy operation and disassembly What happens if you reuse a torque to yield bolt? These bolts cannot and should not be reused due to the stress
caused to the bolt during its first installation. It is important
to be aware that these bolts will not have the same clamping
strength if attempted to be used a second time. Torque-to-yield
bolts may break if reused or become loose over time. A hydraulic bolt tensioning tool provides a quick and easy method
for tightening large diameter bolts to high and accurate pre-loads.
Unlike conventional methods it does not use torque and does not
require any forceful turning of the nut or bolt, like impact
wrenches, flogging spanners or hydraulic torque wrenches. Senda can provide full sets of slitter line tools,such as slitter
knife, rubber bonded rings, spacers, separator discs, hydraulic
nuts and etc. Our Services & Strength 1, We made steel material on our own 2, We provide the custom material for customers 3, We have our own patent material 4, We have professional team to provide on-site training 5, Cooperation with many famous sea, air, courier forwarders 6.
