Rubber expansion joint

Rubber Expansion Joints provide time-tested ways to accommodate pressure loads, relieve movement stresses, reduce noise, isolate vibration, compensate for misalignment after plants go on stream, and prolong the life of motive equipment. rubber expansion joints are available in single – and multi-arch designs and are custom-engineered to fit your application requirements. They are specifically designed to reduce the need for maintenance, repair and manual assistance.

HENANCHANGHONG is one of the leading suppliers of high-quality expansion joint.Designed by the industry’s top experts and available in Single Sphere,Double Sphere,PTFE-lined, Threaded union type,seccentric reducing, concentric reducing,filled arch, lightweight and off-set configurations,and many other products, our products can be used to support a wide range of applications.

1	Outer/inner rubber	EPDM,NR,NBR,PTFE,BR,	Select different materials according to the media
		CR,BR+CR,FKM,Sylopute.
2	Reinforce	Nylon cord fabric	the density and number of layers determine the pressure
3	Pressurized ring	Steel wire strand	Prevent pressure bearing deformation from being pulled off
4	Flange	stainless steel,carbon steel,ductile iron.	Choose different materials according to your requirements
