Bellow Expansion Joint
Our company is one of the leading manufacturers of expansion joints , metallic bellows,flexible metal hose for 10 more years in China.
We offer all types of metal pipe expansion joints. Each type has advantages and limitations that can provide flexibility, load reduction, structural integrity and reliability required in a piping system.
Metal pipe expansion joints can withstand the design temperatures, pressures, as well as, provide the capacity necessary to absorb thermal growth of the piping system. The thermal movement required can be axial, lateral or angular. In some cases, the pressure thrust of a pipe expansion joint must be restrained by the use of tie rods, hinges or gimbal while allowing the bellows to move through its design deflections.

They’re the regular sizes based on pressure of PN16 above, we can design and produce according to users’ detail required sizes and conditions.
Features
1. To absorb effectively vibration, noise,thermal expansion from pipeline system;
2. To resolve minor deviation because of piping connecting and eliminate the pipeline residual stress,compensate axial movements;
3. The bellows can be single,two-ply and multiply in different sizes using precision forming technology.
4. Applied to repeated motion in high temperature areas,good anti-fatigue performance;
5. Good flexibility,resistant to high temperature, resistant to corrosion.
6. Applied in the fields of petroleum,chemical industry,aerospace,metallurgy,electricity, gas,building,mechanical, construction,iron and steel,paper making,fabric,medicine,food and vessels ect.
Application
Pipes with axial displacement by temperature or pressure changes
Heating and air conditioning installation
Hot water and fire protection system
Compressors inlet and outlet
