curved pipe pressure balance type Bellows Expansion Joint nice design CCC certification

Product introduction

The curved pipe pressure balance type corrugated expansion joint is composed of two working bellows connected by a working bellows or intermediate pipe and a balance bellows and elbow or tee, head tie rod, end plate and spherical and conical washer.It is mainly used to absorb the combined axial and transverse displacement and balance the bellows pressure thrust expansion joint.The straight pipe pressure balance type corrugated expansion joint produced by our company is optimized by American EJMA standard.While satisfying the domestic market demand, the products are exported to 22 foreign countries.It is widely used in the connection of aerospace, navigation, petrochemical, smelting, power plant, information industry, industrial equipment manufacturing and engineering pipelines, effectively ensuring the high safety performance of pressure pipelines when transporting various harmful, toxic, inflammable and explosive media, and avoiding Marine, air and factory environmental pollution caused by leakage pollution.Its products are characterized by high temperature resistance, high pressure resistance, corrosion resistance, fatigue resistance, wear resistance.
