Why Choose US
1.All expansion joints are finshed with retaining flanges,limit rod units are available on special request.
2.Pressures shows are recommended"operating",test pressure is 1.5time"operating",burst pressure is 3 time"operating".
3.Vacuum rating is based on neutral installed length without external load.Products shall not be installed "elongated"on vacuum applications.
4.Do not weld near the expansion joints or weld the steel flanges to the piping after the expansion joints are installed .This will either burn or seriously damage the expansion joints.
Our Product Specifications in this catalogues for reference only. Our reserve the right to change design ,
construction,specification and materials without prior notice and without incuring any obligation.Any precise measurements,kindly contact with XINBO technical service directly.
