Flexible Rubber Expansion Joints exports to the United States


 Flexible Rubber Expansion Joints exports to the United States

 Double Sphere Flexible Rubber Expansion Joints exports to the United States a well-known construction company. The construction company is belonging to Fortune 500 companies.The company purchased a ND2000 / pn10, L420 double sphere flexible rubber expansion joints. flange material change is carbon, rubber sphere material is EPDM.Tthis products is mainly used in the tunnel drainage system. January 15 American customers after installation and commissioning of the product, said he was very satisfied. Welcome to American customers buy Zhengzhou Mason Single Sphere Flexible Rubber Expansion Joints.

The DoubleSphere is a Metrasphere with greater compression, elongation and angular movement.

The DoubleSphere is used exactly as its single sphere counterpart, the Metrasphere. Its unique shape and longer length increases acoustic resistance and dampens hydraulic surge and shock.

Constructed of neoprene* and nylon (other materials are available see charts below), the spherical shape allows pressure to exert itself uniformly in all directions, thus reducing the force exerted on pipe lines and equipment. Bias-ply tire cord provides strength, a high safety factor, and low force to move. Precision molding provides a dense, uniform carcass.

Solid plate steel flanges grip the sealing area and provide a fluid tight connection. All flanges are tapped or drilled to mate with 150# companion flanges. The tapped bolt holes and rotatable flanges make installation easy. The arch is self-cleaning, thus eliminating the need for filled arch when solids are present in the stream.




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.
