What should be checked before the rubber expansion joint comes out of HuanZhong factory?

The application area of rubber expansion joint is wide, and it is used in chemical, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire fighting, electric power and other basic projects.
Rubber soft joints can be made into various varieties of acid-resistant, alkali-resistant, corrosion-resistant, oil-resistant, heat-resistant, etc. according to different materials, and adapt to a variety of media and environments. Pressure test: HuanZhong needs to determine the product type specification before the test starts, because we need to prepare a sample of this type of pipe in the pressure test.
Quality inspection test: carry out water pressure test, and carry out water pressure test on rubber soft joints produced every day. To avoid its leakage and keep its good performance.
The surface cracks of rubber expansion joints in the pipeline, corrosion conditions, deformation fatigue, heavy skin, thermal reaction and some other basic conditions joints, such as cracks, deformation, misalignment and other conditions, thickness detection, mainly to prevent media corrosion, leakage caused by impact and full hidden danger. Test method, each section of the pipeline test points shall not be less than three points. If the problem is found to focus on testing to find out the weak areas. Pipeline cracks, rubber joint seam inspection, should be rubber joint seam, the surface of the joint and flange connection bolts to do inspection general pressure-resistant rubber expansion joint inspection cycle, at most once every two years.
