Function or use: A kind of connecting pipe fitting commonly used in pipeline installation. It connects two pipes with the same nominal diameter or different diameters to turn the pipeline at a certain angle. The nominal pressure is 1-1.6Mpa.

product description:

1. Since most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are turned into grooves, leaving a certain angle, with a certain side, this requirement is also strict, how thick the side, the angle and the deviation The scope is specified. The surface quality and mechanical properties are basically the same as the pipes. For the convenience of welding, the steel grades of the pipe fittings and the connected pipes are the same.

2. All the pipe fittings have to undergo surface treatment, the iron oxide on the inner and outer surfaces are sprayed off by shot blasting, and then coated with anticorrosive paint. This is for export needs. Furthermore, in China, it is also for the convenience of transportation to prevent corrosion and oxidation.

3. It is the packaging requirements. For small pipe fittings, such as exports, it is necessary to make a wooden box, about 1 cubic meter, which stipulates that the number of elbows in this box cannot exceed one ton. But the total weight should generally not exceed 1 ton. For large items y, it must be packaged individually, like 24 ″, it must be packaged individually. The other is the packaging mark. The mark is to indicate the size, steel number, batch number, manufacturer's trademark, etc.

The elbow is a kind of pipe fitting used at the turning point of the pipeline. Of all the pipe fittings used in the piping system, the largest proportion is about 80%. Generally, different forming processes are selected for elbows with different materials or wall thicknesses.
