Product Description

Flexible rubber expansion joint can also be called: flexible rubber joint, rubber soft joint, soft joint, flexible rubber joint, etc. it is a pipe connector with high elasticity, high air tightness, medium resistance and weather resistance. Rubber flex joint is a kind of composite rubber pipe which is composed of inner rubber layer, fabric reinforcement layer (the reinforcement layer has multi-layer scraped nylon cord), middle rubber layer, outer rubber layer, end reinforced metal ring or steel ring, and loose combination with metal flange or parallel joint after high temperature and high pressure vulcanization. The rubber expansion of joints makes use of the advantages of rubber, such as high elasticity, high gas resistance, medium resistance, weather resistance and radiation resistance. Rubber expansion of joints can reduce the vibration and noise of the pipeline, and compensate the thermal expansion and cold contraction caused by temperature change.

NO	Name	Material
1	Reinforcing ring	Hard Steel Wire
2	Flange	Q235,SS304,SS316,PVC
3	Reinforcing cord	Nylon Tire Cord
4	Inner/outer rubber	NR,NBR,EPDM,FKM,PTEF,IIR,CR

 Performance characteristics of rubber joints:

1.Small size, light weight, good elasticity, and easy installation and maintenance.
2.During installation, lateral, axial, and angular displacement can be generated, without being limited by pipeline misalignment or flange non parallelism.
3.It can reduce structural transmission noise and has strong vibration absorption ability during work.
