Stainless steel stamping elbows are divided into hot-rolled (extruded) seamless elbow fittings and cold-drawn (rolled) seamless elbow fittings because of their different manufacturing processes. Cold drawn (rolled) pipe is divided into round pipe and shaped pipe.
What improvements do you need to make to the development of stainless steel pipe stamping elbows?
1, add Ni to improve the stress corrosion resistance;
2, reduce C or add Ti, Nb, reduce the intergranular corrosion tendency;
3, add S, Se to improve the machinability and component surface accuracy;
4, add Mo to improve pitting corrosion and crevice corrosion resistance;
5, add Ni and Cr to improve high temperature chemical reactivity and strength.
Stainless steel stamping elbow is processed with stainless steel straight pipe and deformed. Stainless steel stamping elbow in different applications, it may be based on the actual needs, the shape of the re-processing, to make it more convenient to use, in fact, the following is a specific introduction to several common deformation of stainless steel stamping elbow.
1, stainless steel stamping elbow variable wall thickness pipe fittings, refers to the direction of the length of the pipe to make the wall thickness change;
2, the straight pipe into a bend of different curvature radius, such as stainless steel stamping elbow, stainless steel elbow and so on.
3, stainless steel stamping elbow variable diameter pipe fittings, refers to the diameter of the pipe end or a part of the pipe reduced; Pipe fittings with rolling edge and sealing bottom, pipe fittings that increase the total strength of the pipe end to the outside or inside of the pipe edge or seal the end of the pipe;
4, change the section of pipe fittings, according to the requirements, the circular section into square, oval, polygon and so on;
5, stainless steel stamping elbow with a flange refers to the pipe end to the inside or outside convex, round edge: in the direction of the circumference of the pipe to form a raised or notched pipe fittings;
