Description

The Expansion Bellow Calculation has good comprehensive performance, so it is widely used in basic engineering such as chemical engineering, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electricity, etc. According to different materials, it can be made into various varieties such as acid resistance, alkali resistance, corrosion resistance, oil resistance, high temperature resistance, radiation resistance, wear resistance, aging resistance, etc., suitable for various media and environments.

When installing Expansion Bellow Calculation, the screw of the bolt should extend to the outside of the joint.The bolts on the end face of each flange should be tightened evenly and repeatedly, and pressed diagonally to prevent bias.The fastener joint shall be tightened by standard wrench, and shall not be made to slide, slide and break by force of the stiffening stem, and shall be checked periodically to avoid loosening resulting in disassembly or water seepage
