The Study Of Invalidation For Bellows Heat Exchangers In Heat Net

In the chemical industry production process ,since day-to-day contact acid , alkali, salt and organic dissolves to cross a river etc the strong corrosiveness medium , the corruption harm of equipment is a great and real problem .The especially development along with modernize industry is asked at high temperature and the high pressure and the harsh production operating mode condition of continuous operation , and in a single day having appeared equipment to corrode destroying , the whole device will be compelled to stop work , causes easily the dashing forward nature sending out accident such as the explosion of chemical industry equipment and fire etc , even creates great production and living body of a human being injuries and deaths accidents , the economic loss can not estimated . Developing the equipment protects corrosion to study , and retards and controls the corruption of metal , and reduces the loss of metal material , and avoids the corruption to create bigger harm to mankind society and matter resources , and possesses the history meaning of important technology , economic meaning and profound and lastingUsed a large number of heat exchangers in the production and construction courses of oil field , and use the application of the rippled-duct heat exchanger of !Crl8Ni9Ti's steel process sending up the trend risen at present .But making to mangage the list of son remnant to pull existing some problems on stress as well as the material composition , the synthetical effect of various factors such as the corrosiveness medium of existence in the heat exchange system etc causes the heat exchanger emergence stress etching leakage accident to because the unsuitable handle process in the manufacturing course of heat exchanger pistil , influences normal produces , creates very greatly economy losesResearch and inquirement have been carried on to stainless steel etching machine reason and the occur basic condition of stress etching and the corrodes cause is analysed and control way etc the aspects to the corruption problem be dead against the large-scale bellows heat exchanger of petroleum chemical industry of this subject , and have put forward the corresponding anticorrosion measure.
