Specifications

Product Description
The most reliable manufacturer of steel bellows
1 More than 24 years experience of manufacture of expansion joint.
2 The Main Drafter of Chinese Standard GB/T 26121-2010.
3 Approved supplier for nuclear power industry.
4 The top 3 expansion joint manufacturer in China;

stainless steel bellow
1 Stainless steel bellows expansion joint is also known as expansion joint or expansions bend.
2 The main body is the bellows (a flexible element), and it is also composed with some accessories like side tubes, brackets, flanges and conduit tube etc.
3 It is a kind of compensation components. By using the bellows affect extensional deformation, to absorb pipe, ducts and containers axial, lateral and angular displacement.
4 It is also widely used for industry noise reducing and shock absorption.

Feature

1. Shock absorption
2. Easy installment and keep up
3. Resistant to medium and temperature, pressure
4. Greatly reducing vibration and noise, pipeline system but can not solve all kinds of pipe interface displacement, degree of axial stretching problems.
5. Adapt to various of media and the environment like acid, alkali, corrosion, oil heat and other kinds of circumstances
6. Its material is a polar rubber, sealing,
7. Light weight, small size and softness, durable use.
8. Widely used in aviation, aerospace, petroleum, chemical industry, metallurgy, electricity, paper, wood, textile, construction, pharmaceutical, food, tobacco, transportation and other industries.
