Technical requirements for carbon steel elbows

Carbon steel elbow most used for welding, in order to improve the welding quality, the end of the car into a groove, leave a certain Angle, with a fixed edge, this - requirements are more strict, how thick the edge, how much Angle and deviation range are specified. The surface quality and mechanical properties are basically the same as the pipe. For the convenience of welding, the fittings are of the same steel as the pipe to which they are connected.

That is, all carbon steel elbows should be surface treated, the inner and outer surface of the oxide sheet by shot peening treatment, then coated with anticorrosive paint. This is for export needs, moreover, in China is also to facilitate transportation to prevent corrosion and oxidation, we need to do this work.

Is the packaging requirements for small pipe fittings, such as export, it is necessary to do wooden cases, about 1 cubic meter, the provisions of this kind of box elbow number about not more than a ton, the standard allows sets, that is, a small set, but the total weight can not exceed 1 ton. For large items, you need to pack them individually, like 24 "ones.
