How to use bellows metal flexible connections you need to know
Foreign metal attached to the bellows metal flexible connections caused by rust conditions are generally not very serious, you can use a sponge or cloth, will be neutral detergent or soapy water, etc. will be able to simply remove the rust on the bellows metal flexible connections. Like factories or city streets with heavy traffic in the region more harmful substances in the air, so the surface of the bellows metal soft connection is simple to be contaminated, a long time in this condition of the bellows metal soft connection may present small rust spots. If the bellows metal soft connection pollution is relatively light, then you can follow a little method of rust removal, you can clean, if the pollution is more serious, then you have to change the way to clean up.
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.
The bellows metal flexible connection, at room temperature, has an austenitic arrangement of stainless steel. The bellows metal soft connection contains about 18% Cr, 8% to 10% Ni, C about 0.1%, with a stable austenite arrangement. Austenitic bellows metal soft connection contains the famous 18Cr-8Ni steel and on the basis of this add Cr, Ni content and participate in Mo, Cu, Si, Nb, Ti and other elements developed by the high Cr-Ni series of steel. The bellows metal soft connection is non-magnetic and has high toughness and plasticity, but the strength is low, and it is impossible to strengthen it by phase transformation, and it can only be strengthened by cold working. Such as participation in S, Ca, Se, Te and other elements.
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.
