Import Di Dismantling Joint — Buy in Bulk from Supplier in China

Ductile iron dismantling joints from Jilin Senfeng Pipe Co., Ltd. are engineered for modular pipeline assembly in water supply and wastewater systems, allowing axial and angular movement during installation. These joints are manufactured in sizes from 3 inches to 36 inches and designed to accommodate standard ductile iron pipe with push-on or mechanical joint connections. The component includes a flexible rubber gasket and a locking collar system to maintain pressure integrity under dynamic loads.

The body is cast from EN 1563 S500-7 grade ductile iron, with a minimum tensile strength of 500 MPa and elongation of at least 7%. Internal surfaces are coated with cement mortar lining per ISO 4179, while external surfaces receive a fusion-bonded epoxy coating for corrosion resistance in buried or humid environments. The joint’s flexibility allows up to 5 degrees of angular deflection, reducing stress on connected pipes during ground movement or thermal expansion.

These dismantling joints are primarily purchased by municipal water authorities, civil engineering contractors, and infrastructure developers for rehabilitation projects and new pipeline networks. Buyers require joints compatible with ISO 2531 or AWWA C151 standards. Trade terms are typically FOB Dalian or CIF port of destination, with minimum order quantities starting at 100 units. Lead time averages 25 to 35 days after order confirmation, subject to casting and coating schedule.
