Cooling water hose has a wide range of application
Rubber hose is an indispensable material in modern industry. While most of the hoses currently on the market are corrosion resistant. But it will still suffer from corrosion. Why corrosion resistant hose get corroded? Then Orientflex will introduce you.
Factors that cause corrosion to corrosion resistant rubber hose
First, the pickling process leads to corrosion leaks. Pickling is usually used to remove the thin oxide layer produced by welds and heat-affected zones. However, the time and temperature of pickling are difficult to control. At a certain temperature, if the pickling time is too long, it will cause excessive corrosion of the bellows and make the surface dark and dull. In severe cases, it will turn iron gray. The pickling temperature is too high and the surface is rough and dark gray. Corrosion zones may even appear in the heat-affected zone of the weld. All of the above factors can cause corrosion and perforation.
Second, the the quality of the rubber pipe affect the corrosion resistance. The demand to rubber pipe is larger and larger. Then there are more and more hose suppliers. However, not all of them can provide you qualified hose. In fact, many factories use recycle materials to replace the high quality raw materials. Then there may be impurities inside the hose. As a result, the corrosion resistance and other properties will be much lower.
When corrosive media and special active anions (such as chloride ions and sulfide ions) pass through the pipeline, the weak points of the passivation film will be destroyed at the edge of the weld fusion line. Corrosive penetration micropores are formed, causing pitting corrosion and leakage. Therefore, we must do a good job in preventing corrosion of rubber hoses.
