1. Since most pipe fittings are used for welding, in order to improve the welding quality, the end parts are beveled, with a certain Angle and a certain edge. This requirement is also strict. The surface quality and mechanical properties are basically the same as pipes. For the convenience of welding, the pipe fittings are of the same steel grade as the pipe to be connected.
2. All pipe fittings should be surface treated. The iron oxide on the inner and outer surfaces should be sprayed off by shot peening, and then coated with anticorrosive paint. This is for export needs, moreover, in order to facilitate transportation to prevent corrosion and oxidation, we must do this work.
3, is the packaging requirements for small pipe, such as export, you need to do wooden cases, about 1 cubic meter, the number of elbows in the box can not exceed about a ton, the standard allows the set, that is, a large set of small, but the total weight generally can not exceed 1 ton. For large pieces y needs to be packed individually, like 24 "must be packed individually. Another is the packaging mark, the mark is to indicate the size, steel number, batch number, manufacturer's trademark, etc.
