Prestressed metal bellows used in the construction of prestressed metal bellows only large companies can produce high-quality products produced. Prestressed corrugated metal pipe production scale big reason for that is because there must be prestressed corrugated metal pipe research and development of professional and technical personnel design, production of qualified products for comprehensive sales, will qualify prestressed corrugated metal pipe go to the construction. Prestressed corrugated metal pipe used in municipal roads and more high-rise buildings, electricity business buildings. It has different models have different specifications, installation time is very convenient. Prestressed metal bellows stable quality, resulting in the advantages of safe and reliable. Prestressed metal bellows shape structure is very beautiful, light weight car bellows, easy to use. The majority of the advantages of auto bellows installed, get people's praise. Stainless steel corrugated metal hose manufacturer in order to clarify the role of this type of weld metal bellows manufacture, we need to look at the entire manufacturing process, some of the steps. Welded metal bellows from one of the most common is for the washer-shaped metal foil begin processing. These sheets are made of a metal stamping blank strip, typically having a thickness between 0.025 a 0.254mm. Round washer-shaped sheets to the processing 周向波 pattern with matching relations, and is squeezed into a slightly tapered shape of the car bellows, each pair of corrugated sheets to the opposite cone. When a pair of sheets are placed together, let contact the inner surface, they seem to taper towards each other away from the outer surface thereof. If more when the same is placed on one end of the sheet with a pair of thin, we can see a metal bellows shape. For the manufacture of such welded metal bellows, requires two welding operations: the inner edge of welding, sheet connected to a pair of pleated bellows offer cars circle the outer edge welded to each connected to a metal ring pleated bellows. Two kinds are used GTAW welding or PAW (micro-plasma) welding the edges. In addition, because the terminal device without welding metal bellows in any occasions are easily damaged, so, you also need to add a third weld welding terminal.
