Because most pipe fittings are used for welding, in order to improve welding quality, the end of the car groove, leave a certain Angle, with a certain edge, this requirement is also more strict, the thickness of the side, the Angle is much and the deviation range are specified. The surface quality and mechanical properties are basically the same as the pipe. For easy welding, the steel of the fittings is the same as that of the pipes to be connected.

That is, all pipe fittings should go through surface treatment, the inner and outer surface of the oxide sheet is sprayed off by shot peening, and then coated with anticorrosive paint. This is for export needs, in addition, in order to facilitate transportation to prevent corrosion and oxidation, we should do this work.
