Qfi Ball Carbon Steel Adjustable Pipe Joint

Product performance:
The product 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.
Method of application:
Gland loose tube 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.
QFI ball carbon steel adjustable pipe joint applies to pipeline connection which request great angular deflection. It is decomposed with body and sealing ring. The body can rotate greenly around the ball center to compensate the pipe's heat expansion, displacement and deflection after installed on the pipe. The advantage is high compensation ability. Few rooms, low hydro resistance, easy installation and low investment. It may apply to the pipe with tri-directional displacement.
