1. Since most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are all turned into bevels, leaving a certain angle with a certain edge. This requirement is also stricter, the thickness is too thick, the angle is how much and the deviation The range is specified, the surface quality and mechanical properties are basically the same as the pipe. For the convenience of welding, the pipe is the same as the steel of the pipe to be connected.
2, that is, all the pipe fittings must be surface treated, the iron oxide skin on the inner and outer surfaces is sprayed off by shot peening, and then coated with anti-corrosive paint, which is for export needs, and in addition, it is also convenient for transportation to prevent corrosion and oxidation in China. All have to do this work.
3, is the requirements for packaging for small pipe fittings, such as exports, you need to do wooden boxes, about 1 cubic meter, the number of elbows in this box is not more than one ton, the standard allows the suit, that is, large sets, However, the total weight can not exceed 1 ton. For large pieces, y must be individually packaged. For example, 24" must be packaged separately. The other is the package mark. The mark is to indicate the size, steel number, batch number, manufacturer's trademark, etc.
