Detailed analysis of the selection, storage and life testing of rubber expansion and shock hoses

Rubber expansion and contraction shock hoses are more common in chemical pipelines. It is used in chemical machinery and equipment such as conveying pipeline, exhaust pipe, steam pipe, hydraulic oil pipe of rolling mill, aircraft hydraulic system, cold pressure system, distillation tower, heat exchanger, kettle, tower, tank lining, gate valve, etc.
In the past application of rubber soft joints, due to the entry of some corrosive substances, the performance index of rubber soft joints often reduces the performance of rubber soft joints because they can't stand corrosion. The damage caused by the natural environment that cannot meet the temperature, working pressure and organic chemical compatibility is very alarming. Because of its corrosion resistance, PTFE raw material has become a key corrosion-resistant material in petroleum, chemical plants, textile and other fields. Anti-pull device, also known as limit anti-pull device, is based on the performance of the original product to increase the limit device. Good elasticity, strong shock absorption, can effectively reduce noise vibration. General sewage and weak acid and alkali water quality can also be connected by high temperature medium fluid. If the pipeline expansion and contraction is large, you can choose to use double spheres. The disadvantage is that the pressure is not as large as the single sphere.
When selecting a rubber expansion and contraction shock absorber, the diameter and working pressure of the rubber joint need to be taken into consideration first. When it comes to the compensation amount of rubber flexible joints, in repeated working situations, the surface chain of rubber molecules breaks to produce free radicals. Therefore, in the case of large compensation amount of the pipeline offset joint, it is strictly prohibited to adjust the excessive size tolerance of the pipeline. What are the storage standards of rubber expansion shock absorbers, each package should have a certificate of conformity, and marked with the product name, commodity identification, trademark logo, manufacturing license number, production plant name, place of production, date of manufacture, product implementation standard identification code. Within 12 months from the date of manufacture, the commodity characteristics should meet the requirements.
Rubber expansion shock throat life test ignition method: take a few test products and burn in the air. Check the phenomenon. Generally speaking, fluorine rubber, CR, CSM basaltic fire since the rest, even if the ignition spark is better than usual. Naturally, if you look carefully, the ignition condition, hue, and taste will also supply a lot of information for everyone. For example, NBR/PVC and with glue, when there is an open flame, the fire will splash.
