1. Due to the fact that most metal bent pipe fittings are used for welding, in order to improve welding quality, the ends are turned into grooves with a certain angle and edges. This requirement is also quite strict, and there are regulations on the thickness of the edges, the angle, and the deviation range. The surface quality and mechanical properties are basically the same as those of pipes. For the convenience of welding, the steel grade of the pipe fittings and the connected pipes is the same.

2. All pipe fittings must undergo surface treatment, where the oxide scale on the inner and outer surfaces is shot blasted off and then coated with anti-corrosion paint. This is for export needs, and also for the convenience of transportation in China to prevent corrosion and oxidation, all work in this area needs to be done.

3. The requirement for packaging is that for small pipe fittings, such as exports, a wooden box needs to be made, approximately 1 cubic meter. It is stipulated that the number of elbows in this box cannot exceed one ton. This standard allows for a set, which is a large set with a small set, but the total weight generally cannot exceed 1 ton. For large items y, individual packaging is required, and for items like 24 inches, individual packaging is required. In addition, there is packaging marking, which should indicate size, steel grade, batch number, manufacturer's trademark, etc.
