Stainless steel metal bellows leak testing is an advantage of the necessary steps to stainless steel bellows I think we all know it, but the parents who know that stainless steel bellows as a conduit advantage of it resistance to bending corrugated pipe absolute quality, it light weight, corrosion resistance advantages, high temperature, shock absorption, and many other, I think these advantages are our friends who are all aware of it. For manufacturing enterprises are paying more attention to the structure and production costs, so as to run smoothly and reliably. Whether it has a reasonable long-term significance, then how to ensure that the stainless steel metal bellows can be normal and orderly development of our products for a reasonable degree of reliability in product design and testing to decide. Usually there are so few testing process, including: appearance, size, pressure, tightness, yielding degree. Wherein for tightness testing metal bellows steps must be done before the factory belongs to, the other based on customer needs, selectivity. Pressure testing of stainless steel metal bellows, which are of safety indicators. When the pressure test when the metal bellows raise 1.5 times the pressure at the time to experiment corrugated tube bending resistance range, experiment with the medium can be water-resistant curved bellows ease of use, or air, if water wherein the chloride ion content is lower than 25, for each stainless steel metal bellows should be carried out. It can be electric or manual pressure, usually 1.5 times the design pressure. Experiment, the metal bellows flat, one connecting pipe water into the tube, then slowly pressurized, pressure for 5 minutes to check leaks, must promise not to divulge this is essential. For leak testing of stainless steel metal bellows steps necessary majority of my friends learn it? Performance okay prestressed metal bellows? That performance is more important prestressed metal bellows material is not only one, but the plastic material is certainly one of them. This material is plastic bellows used in production is HDPE. It is in the production of plastic products when the material will be used. From a performance point of view, the main properties of plastic products is the ability to have a higher corrosion resistance and better acid resistance. This is also the chemical properties of the bellows itself can have, because the bellows does not corrode, it can make Tendons in the long run will not be etched some chemicals. You know, prestressed structures reside in the environment is not much good environment. Prestressed metal bellows used in such an environment, if there is no corrosion protection in use, the effect will be more bad. For example, the brine would be a threat to the bellows performance. Coupled with the emergence of waterproof layer if there is a crash, etc., the problem will be more serious. Experts said that indeed the case, and some micro-cracks leaking drains clogging can occur in prestressed structural use. At this time, the plastic structure prestressed metal bellows would really protect the equipment against corrosion. Because the anti-corrosion properties of metal tubes really can not be always be able to corrosion. After exposure to a variety of water as long as there will be a long time corrosion. In fact, a key factor in the use of plastic bellows indeed is its resistance to corrosion. Ocean Bridge Prestressed manufacturers expressed resistance to bending shaped bellows, it is also a barrier protection, to avoid harmful substances into the duct inside. Because these protections, the use of time throughout prestressed structures can grow a lot. Of course, pre-stressed metal bellows and many properties. Now I do not describe to people.
