Product Description

The spool type rubber expansion joint is mainly composed of three parts: rubber joint, flange, and metal rod. Its structural design is reasonable, simple, and easy to install, making it a new type of pipeline connector. Compared with ordinary rubber joints, spool type rubber joints can better adapt to the axial and radial displacement changes of pipelines, and have certain angular displacement and deflection angles. In addition, spool type rubber joints rubber joints can also improve the load-bearing capacity of pipelines by increasing the thickness of the connecting flange.

NO	Name	Material
1	Flange	Q235,SS304,SS316,PVC
2	Inner/outer rubber	NR,NBR,EPDM,FKM,PTEF,IIR,CR
3	Reinforcing cord	Nylon Tire Cord
4	The rod	Carbon steel,Ductile iron,Stainless steel

The spool type rubber expansion joint has excellent physical properties:
1.Pressure resistance, corrosion resistance, high temperature resistance, oil resistance, able to adapt to various complex working environments.
2.Shock absorption and noise reduction effectively block the propagation of sound, reducing vibration and noise in pipeline systems.
3.Good sealing performance, using high-quality rubber materials and high-strength metal structures to ensure tight connections and prevent medium leakage.

Application

Spool type rubber expansion joints can be widely used in water supply and drainage, circulating water, HVAC, fire protection, paper making, pharmaceutical, petrochemical, ship, pump, compressor, fan and other pipeline systems. The ordinary type is used to transport air, compressed air, water, seawater, oil, acid, alkali, etc. ranging from -15 to 115. Special rubber flexible joints are used for conveying media or oils, concentrated acids and alkalis, and solid materials above -30 to 250.
