Product Description

 

Externally Pressurized Expansion Joint

 

Feature:

1. To Absorb large axial displacement between straight tube and support frame , and small horizontal displacement;

2. To resolve minor deviation because of piping connection and eliminate the pipeline residual stress;

3. Easy cleaning and maintenance.

Applications: For the chemical industry, metallurgy, electricity, shipbuilding, construction and other industries.

Application temperature:-50 ºC~300ºC.
