Pipe expansion joint is manufacture through welding or metal casting ,and the loosing part is sealed by echelon ring rubber .operated by gland and bolt and based on the principle of rubber’s elastic deformation under pressure ,the seal ring will be deformed and static seal will be done between joint body and expansion pipe wall .according to clients demand and product performance ,metal and seal ring materials will be selected strictly .high strength antifouling paint is painted outside and the joint bolt is made of high strength carbon steel or stainless ,since there is some space between body and expansion ,so axes and radial displacement will appear .inside pipe ,it become available to compensate and release pipe blind plate propulsion and make it easy to maintain and change pump and valve .therefore ,it is an ideal matching product for pipes’ installation and operation.
Steel flange joints expansion joints is a new product pumps, valves, piping and other equipment and pipe connections, through its wholly-bolts to connect them to become whole, and there is a certain amount of displacement, easy installation. Can withstand axial pressure pipeline. This can be in the installation and maintenance, according to the site installation size adjustment, at work, not only improve efficiency, but also for pumps, valves, piping and other equipment they play a protective role.
Method of application:
Pipe expansion joint is on the basis of the original pipe set of expansion joint performance ,add spacing device ,the gland loose tube type expansion joint scale biggest place with nut locking ,such pipes in allowing scale expansion freely within the maximum rang of color ,once more than gland loose tube type expansion joint of the largest scale .limit effect ,thus ensuring a gland type loose tube expansion joint of the pipe run normally ,especially suitable for the vibration or have a certain slope at the corner or the pipe.
