Fastening process characteristics of stainless steel elbow

- Nov 09, 2018 -

The fastening process of stainless steel elbows is the second type of dry warfare practice. The characteristic of the process is that the continuous casting fertilizer slab has central segregation, which eliminates the technical problem of the quality of the stainless steel stamping and bending pipe fittings.

The quickening effect of the stainless steel stamping elbow is not only determined by the passivation process, but also by the stainless steel tube stamping and bending data itself. The detailed influencing factors are not the stainless steel metallographic structure exposed by the stainless steel stamping elbow. The state of reduction of stainless steel, etc.

Any stainless steel stamping elbow machine, if there is plating or the rest of the coating to be supplied, it is common to pre-dispose (including pickling, rubbing, throwing light, etc.) through passivation, the ability to apply or disassemble the defective parts. Passivation can improve the stability of the stainless steel stamping elbow in the external environment to prevent the partial corrosion of the stainless steel stamping elbow, so that there is enough cleanliness in the stainless steel stamping tail and can eliminate the stainless steel stamping elbow Appearance warming reduction of agricultural oxides.

The plate used for stainless steel stamping elbows is 60~70. In the end of the old age, A3 and 16Mn, which are produced in Anchang Steel and other fields, are used. The pipe diameter is reduced and the pressure is lowered. The strength of the pipe plate cannot be satisfied. At the end of the 80s, the petroleum welded pipe fittings factory initially applied pipeline seamless pipes that were born in accordance with the API scale of the good state. Because the international stainless steel stamping elbow division factory technology is not naive, it is important to adopt the export plate.
