In the piping system, elbows are pipe fittings used to change the direction of the pipe. According to the angle, there are three commonly used types: 45°, 90° and 180°. In addition, according to the needs of the project, there are other non-normal angle elbows such as 60°. The materials of the titanium elbows include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals, and plastics.
1. Since most pipe fittings are used for welding, to improve the quality of welding, the ends are processed into grooves with certain angles and edges. This requirement is also quite strict, and the thickness, angle, and deviation range of the edges are specified. The surface quality and mechanical properties are the same as those of the titanium elbow. To facilitate welding, the pipe fittings are of the same steel grade as the connecting pipes.
2. All pipe fittings must be surface treated, the oxide scale on the inner and outer surfaces must be shot peened, and then anti-corrosion paint must be applied. This is for export needs and to facilitate transportation in China to prevent corrosion and oxidation, and all work in this regard needs to be done.
3. The packaging requirement is that for small pipe fittings such as exports, a wooden box of about 1 cubic meter needs to be made. According to regulations, the number of elbows in this box cannot exceed one ton. This standard allows one set, that is, a large set and a small set, but the total weight usually cannot exceed 1 ton. For large items, they need to be packed separately. In addition, there are packaging marks, which should indicate the size, steel grade, batch number, manufacturer's trademark, etc.
The above is all about the application of titanium pipe fittings elbows. If you have any related questions, please feel free to consult us.
