1.Flexible rubber bellow introduction:

1) Flexible rubber bellowcan greatly reduce pipeline system shock and noise.

And canfundamentallyresolve pipe joints displacement, axial stretch and non-concentricity.

2)By using different materials, rubber expansion joints can be made many kinds to cater

for differentmedium andenvironment. Such asacid resistance, alkali resistance, corrosion

resistance, oil resistanceandheat resistance etc.

3)The material is pure rubber, sealing is very good. It is in light weight, very easy for installation.

Rubber expansion joint has long life performance, but must be not contact with sharp metal

instruments to avoid piercing the sphere.

4)Rubber expansion joints can be used for lift and transportation of raw water and sewage,

transportationof water supply cooling cycle water thermal power ,condensate water of metallurgy

industry and chemical industry.

4. Flexible rubber bellow production progress:

1. Raw material: we never use reclaimed raw rubber, II 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 sulfuring 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.Flexible rubber bellow 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.
