Unconstrained corrugated compensator Features: JWY type unconstrained corrugated compensator, also known as unconstrained bellows, unconstrained expansion joints, Buried compensator, bellows inside the compensator using single, double or multi- U-shaped wave, bellows and diversion units 1Cr18Ni9Ti materials such as stainless steel, other materials for low-carbon steel or low alloy steel. Unconstrained bellows bracket spacing is identical to the fixed and fixed to determine the thrust bearing and general computing axial compensator. Unconstrained corrugated compensator canceled except I stretched the work, but also greatly easing the installation requirements. Unconstrained bellows can be the same as a short pipe installed in the pipe, line pipe does not have to press any other method of axial expansion joints usually require a cut and then take a good long pipeline expansion joints and other. Also due to the unconstrained corrugated compensator robust housing, but also to facilitate the transportation, installation and insulation. Unconstrained bellows Uses: unconstrained corrugated compensator to compensate for axial pipe, large amount of compensation, with a strong self-steering and superior bending capability, which can simplify the design of the pipe guide bracket, the guide bracket spacing installation can be adjusted.
