Corrugated pipe / Bellows


The stainless steel bellows :  high sensitivity, reliable performance and long life and so on.

It could be as sensitive elements in the automation instruments, as mechanical seal elements in vacuum devices,  valves,  mechanical(vacuum) pump and accessories, as transmission elements(flex ible coupling) in automat ion control system and as axial, lateral compensation function in piping systems.

Bellows products are widely used in machinery, petrochemical. electric power, textile, metallurgy,  shipbuilding, aerospace and other fields With the introduction of foreign advanced technology and the rapid development of the domestic

modernization, metal bellows has been involved in solar collector power generation and energy use, intermediate frequency furnace smelting equipment , LNG cryogenic equipment system .

Our company mainly produces products: S type bellows, u-shaped bellows, Ω type bellows, etc.
