Rubber Expansion Joint

Rubber expansion joint is widely used in the field of chemical industry, construction, supply water, sewage drainage, petroleum, light and heavy industry, sanitation, plumbing, electricity and other fundamental engineering.

Dismantling Joint

Dismantling Joints are used to connect Flange on the one side and weld pipe on the other,modulate the product's length in between

Duckbill Check Valve

Duckbill check valve is a simple, reliable, cost effective method of backflow prevention. The series flange integral duckbill check valve is designed to be installed between two mating flanges.

Expansion Bellows Compensator

Metal bellows expansion joints (also called Metal Expansion Joint) are compensating elements for thermal expansion and relative movement in pipelines, containers and machines.


Valve is not only own with the functions of opening quickly, easy to maintain, good sealing but also safety fire-safe and Antistatic designs.

Shock Absorber

Shock absorber is adopted in ductile iron, which improves the plasticity and toughness of the product, and the strength of the steel is higher than that of the carbon steel

Pipe Accessory

S312,S404 Water-Proof Sleeve is generally applied to the structure with requirement of vibration or water proof in the position.
