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;

TNY, BPDZ flange axial internal pressure type expansion bellows consist of a corrugated pipe and two side flanges (also can be made into over type).The deformation of bellows realized pipe axial displacement (also have a small amount of transverse and angular displacement). The small pull rod function is mainly the rigid support in the process of transportation or as a product predeformation adjustment; it is not load bearing parts.

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. Reasonable structure, good elasticity, large range of compensation pipeline and little counterforce to the brackets of pipeline.

2. Shock absorption and noise decrease, heat and dust insulation, environmental protection and simple structure bracket.

3. The displacement can be deflected to prevent damagment caused by subsidence of connected brackets and equipment base. It can adapt itself to the centrifugal difference of pipeline installation to provide convenience to installation and maintenance.

4. Good resistance to milling, heat, aging and corrosiveness and long service life.

5. Little resistance and little weight. Each performance is better than the compensation device of other materials.

6. The temperature range of media is wide:-40--300

Applicable

1. Heating and air conditioning installation

2. Hot water and fire protection system

3. Compressors inlet and outlet

4. Pipes with axial displacement by temperature or pressure changes

5. Thermal motors refrigeration circuit
