       Metal SS304 expansion joint is consist of a flexible bellows element,appropriate end fittings such as butt-welded ends or flanges to allow connection to the adjacent piping or equipment,and other accessory items that may be required for a particular service application. All the materials expand and contract with thermal change.In the case of piping systems,this dimensional change can produce excessive stresses throughout the piping system and at fixed points such as vessels and rotating equipment,as well as within the piping itself.
