2.Company Information

Henan Liwei Industry Co., Ltd:
1)Since 1988, Top 3 manufacturer of rubber expansion joint in China;
2)The Main Drafting Committee of National Standard for Rubber Joint;
3)Qualified Supplier for CGN Nuclear Power Plant;
4) ISO9001: 2008 and ISO14001: 2004 Certified.

3.Product Performance:

A) Structure: Rubber expansion joint is the soft joint of metal pipes, and consists of inner rubber, nylon cord fabric, outer rubber and metal lap joint flanges.
B) Technology: We introduce advanced technology from abroad, and combine it with Chinese manufacture experience. In the manufacturing process, the inner side endures high pressure; Nylon cord fabrics and the inner rubber are better combined and can work under higher pressure than normal flexible rubber expansion joint.
C) Features: The inner adhesive layer united perfectly, bright, clean and seamless; The tag adopts the vulcanization process, perfectly matches the product. The products endure high pressure, maintain good elasticity, make large displacement to balance pipe deviation, absorb vibration, make less noise and have easy installation, etc.


4..Rubber expansion joint Features and Benefits
 
 
1)Versatile hand-built construction. Made in China 
2)Absorbs directional movement
3)Absorbs vibration, noise and shock 
4)Compensates for misalignment
5) Wide flowing arch design
6)Virtually eliminates sediment buildup
7)Economical fully molded construction
8)High vacuum rating (up to 30" Hg) can be supplied for certain sizes
9)Special grooved flange ring design, prevent rubber end pulling out
10) Solid galvanized steel floating flanges speed the installation time
11High tensile aircraft cable is embedded in the raised face rubber ends to prevent pull out and avoids the sharp cutting edge of solid steel rings
12No gaskets required; integrally rubber flanged design, no gaskets required, DIN PN10/16 drilling standard, other flange drilling available, including ANSI 150lb/300 lb, BS, and JIS

5.Application Range:

A) Application: Rubber expansion joint is widely used in the pipe systems for water supply, drainage, circulating water, HVAC, fire protection, paper making, pharmacy, petroleum chemical industry, ship piping system, water pump, compressor and fan etc.
B) Applicable Media: The normal type is used to transport air ranges from - 15 ° C to 115 ° C, compressed air, water, sea water, oil, acid and alkali etc. The special type is used to transport the media above ranges from - 30 ° C to 250 ° C, oil or strong alkali, strong acid and solid material.
This is the picture of Rubber Joints produced by Liwei. We can manufacture to specific customer specifications and dimensions on request.

6.Characteristic:

1)This product could primarily reduce the vibration and the noise of the piping system, completely solve the different piping problems as displace of joint, axial flex and etc.

2) According to different material requirement, product could be made as acid proof, corrosion proof to suit different medium and environments.

3) The materials are good sealing, light weighting, easy to fix and maintain, also has long-working expecting. But please keep far away from sharp metal in order to avoid breaking of the rubber body.

4) For flanges of other standards or non-standards. It is necessary to be agreed upon separately. Please specify standard of furnish diagram and relative parameter. We will manufacture accordingly. Rubber material may be selected according t your requirement.

5) Anti-corrosion: EPDM and NBR rubber can bear high temperature and can anti-corrosion.

6) Double sphere flange end rubber joint: The rubber body has two bridges. It can bear more pressure and the length is long than single sphere rubber  joint.

7) The size can made as customer's drawing, we can make mould for special type.

8) They are cost effective, the total cost is low because of rubber is cheap and it have long use life.
