axial pipe expansion joint / stainless steel / carbon steel / for water

Before assembling the joint at the pipeline one must check to ensure that the inside of the body is clean. If compressed air is available use it for greater cleaning. The counter flanges should be parallel and the holes should be aligned. Check the spacing between them which should not be too large or small. Also consider the gaskets along with their flattering according to EN-558-1. The joint should be placed in the correct position the gaskets inserted between the flanges providing as much centering as is available. The bolts should fit into the flange's holes and tightened.
