Stainless steel corrugated metal hose manufacturer in order to clarify the role of welding in the manufacture of this type of metal bellows, we need to look at the entire manufacturing process, certain steps. Welded metal bellows from one of the most common is a washer-shaped metal foil begin processing. The sheets are made of a metal strip blank stamping, its thickness is generally between 0.025 a 0.254mm. Circular washer-shaped sheet to the pattern matching process with 周向波 relations, and is extruded into the shape of a slightly curved taper resistant bellows lowest price, each pair of corrugated sheets to the opposite cone. When a pair of sheets are placed together, let the inner surface of the contact, they look toward the outer surface of the cone to deviate from each other. If more at this end of the sheet is placed on the same sheet of a pair of mating, we can see a metal bellows shape. For the manufacture of such welded metal bellows, requires two welding operations: inner edge welded connection to a pair of pleated sheet ring, the outer edge of the welding, the individual pleats ring connected to the metal bellows. Two kinds of welding are using GTAW or PAW (micro plasma) welding the edges. In addition, since the terminal device without welding metal bellows in any occasions are easily damaged, so, you also need to add a third welding welding terminal. Stainless steel metal bellows leak testing is a necessary step stainless steel metal bellows advantage I think we all know it, but parents who know that stainless steel bellows as a conduit advantage of it, it has a light weight, corrosion resistance, high temperature, shock absorption, and many of the advantages of retail bending resistance corrugated tube, I think these advantages are majority of my friends 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 bending resistance corrugated tube, experiment with the medium can be water, or air, if the water in which the chloride ion content is lower than 25, For each of the 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?
