Product Description

Henan Liwei Industry Co.,Ltd.

Features:
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 to your requirement.
5. Anti-corrosion: EPDM and NBR rubber can bear high temperature and can anti-corrosion.
6. Four sphere flange end rubber joint: The rubber body has four bridges. It can bear more pressure and the length is long than single sphere rubber joint.
7. They are cost effective, the total cost is low because of rubber is cheap and it have long use life.

Our products have the following character:
Good select materials, advanced equipment, skillful workmanship, rigorous quality control standards, attractive design and durability. They are well-known for excellent quality, most competitive price, and lower cost and prompt delivery.
The product is made up of the composite rubber ball, including internal rubber layer, nylon fabric, and external rubber layer and the loose metal flange. With the merits of high pressure, stable elasticity, big displacement, good damping capacity and noise reduction, it is widely used in the systems of water supply, drainage, water circulation, heating and ventilating, and air conditioning, and the piping systems of the paper-making, the petrochemical industry, marine, compressors pumps, fans, etc

Production progress

1. Raw material: we never use reclaimed raw rubber, rubber is imported from USA. Before used, raw material should be tested, including physical test and some chemical experiment to test the hardness and so on;

 

2. Rubber pretreating and ingredients;

 

3. Milling: first, rubber plastication, second, rubber mixing, we will add rubber compounds, like sulfurzing reagent, surfactant, softener, stabilizer, foaming agent and some special compounds, at the same time, rubber will be extruded into plates, cut, produce 45 degree angle. The plates cannot directly be used, they should be cooled about 24 hours;

 

4. Molding: it will cost much time;

 

5. Vulcanizing: the largest vulcanizing tank in Asia ΓΈ5000*15000, right time, temperature, pressure is very important;

 

6.Test and experiment: these tests should be done, hydraulic test, resistance to vacuum, displacement of the performance, rubber physical properties, thickness and the strength and other quality test;

 

7. Package: out package the free of fumigation wooden case; inside package: plastic film and textile membrane.

 
Delivery time:
Within 30 days after receipt of the deposit, or as your request

Packaging details:
Unfumigation wooden case (out package) and plastic film and textile membrane(inside package). We can make change as your request.
