Product Description

Non-Welded metal expansion joint is a type of compensator, which is made of austenitic stainless steel material or materials according to user requirements. It has excellent flexibility, corrosion resistance, high temperature resistance, and high pressure resistance. It can be connected in any direction in pipelines to compensate for temperature and absorb vibration, reduce noise, change the direction of medium transportation, eliminate mechanical displacement between pipelines or pipelines and equipment, etc. Double flange metal bellows hoses are particularly suitable for flexible joints of various pumps, valves, etc. with displacement and vibration.

NO	Name	Material
1	Flange	SS304,ss316,carbon steel,etc
2	Shipping Rod	SS304,ss316,carbon steel,etc
3	Bellow	Stainless steel
4	Welded pipe	SS304,ss306,carbon steel,etc

 

The main characteristics of non welded metal expansion joints are as follows:
 

1.High temperature resistance

2.High pressure resistance

3.Corrosion resistance

4.Long lifespan

5.The compensation amount is large

6.Good sealing performance

7.Vibration and noise reduction

8.Effectively protect pipeline systems, improve system safety and reliability

Note: 1. Special requirements can be customized according to user drawings. The flange standard is GB/T9115.1-2000. Multiple flange standards (GB, JB, Hg, CB, ANSI, DIN, BSEN, NF, EN, JIS, ISO, etc.) can be selected for production. Rubber balls can be used as natural rubber, EPDM rubber, chloroprene rubber, butyl rubber, butadiene rubber, fluororubber, etc. When using products with a diameter of DN200 or above for suspended water supply, the pipeline must have fixed brackets or brackets, otherwise the product should be equipped with anti pull devices.
