Double sphere expansion rubber  joint

Constructed of neoprene and nylon (other materials are available see charts below), the spherical shape allows pressure to exert itself uniformly in all directions, thus reducing the force exerted on pipe lines and equipment. Bias-ply tire cord provides strength, a high safety factor, and low force to move. Precision molding provides a dense, uniform carcass.

Double sphere expansion rubber  joint material:
Double sphere expansion rubber  joint ball is from the inside layer, enhanced multi-layer plastic scraper nylon cord, rubber outer layer composite tubes. Depending on the medium used rubber material is different, there are natural rubber, styrene-butadiene rubber, butyl rubber, nitrile rubber, EPDM rubber, neoprene, silicone rubber, fluorine rubber and so on. Respectively, with heat, acid, alkali, corrosion resistance, abrasion resistance, oil and other functions.

 

Connection:

 

Generally have threaded connection, flange, clamp connection and so on.

 

 

 

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 ø5000*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

 

 

 

 

 

 

 

FAQ

 

 

 

1, double sphere rubber expansion joint during installation, non-super-displacement limit installation.

 

2, mounting bolts should be symmetrical, gradually tightening pressure, prevent local leakage.
3. 1.6MPa more work pressure, pressure pad mounting bolts must be flexible to prevent loose bolts work

 

4 When mounted vertically at both ends of the pipe joints vertical force should be supported, anti-pull-off device can be taken to prevent work under pressure to pull off.
5 double sphere rubber expansion joint connector mounting area away from heat. Ozone area. Prohibited intense radiation exposure and use of this product does not meet the requirements of the media.
6 double sphere rubber expansion joint in the transport handling strictly prohibited sharp cut surface, the sealing surface.
