As the bellows metal flexible connections in the cold drawing before the steel pipe to pickling, phosphating and saponification, after the cold drawing machine directly to the bellows metal flexible connections without heating the mechanical drawing length, it will change some of the mechanical properties of the original bellows metal flexible connections. After annealing treatment, the original mechanical properties and mechanical properties of the metal can be restored, so that the bellows metal flexible connections can be used normally. We all know that annealing can eliminate the residual stress of the bellows metal flexible connections, eliminate the residual stress of the cold drawn bellows metal flexible connections method is to use the annealing process. The bellows metal flexible connections are transported to the annealing furnace through a conveyor belt, and then after processing, the annealing process can be completed.
Corrugated metal flexible connections have outstanding machinability. In addition to the corrugated pipe metal flexible joints resistant to oxidizing acid medium corrosion, if it contains elements such as Mo, Cu, etc. also lead sulfuric acid, phosphoric acid and formic acid, acetic acid, urea and other corrosion. Corrugated pipe metal soft connection in the carbon content of less than 0.03% or containing Ti, Ni, it can significantly improve its resistance to intergranular corrosion function. Corrugated pipe metal flexible connection concentrated nitric acid Ken has outstanding corrosion resistance. Because the bellows metal soft connection has and outstanding inductive function, in all walks of life in a wide range of industries have been used.
