The elbow is a pipe that changes the direction of the pipe. It is very diverse and has a variety of materials.
This elbow is a connecting pipe commonly used in pipeline installation, connecting two pipes with the same or different nominal diameters to make the pipe turn at a certain angle, and the nominal pressure is 1-1.6Mpa.
1. Because 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 is more stricter, the thickness of the edge, the angle and the range of deviation all have requirements. 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. All the surface of the pipe fittings must be treated, and the iron oxide skin on the inner and outer surfaces is sprayed by shot peening, and then coated with anti-corrosive paint. This is for export needs, and in addition, in order to facilitate transportation and prevent corrosion and oxidation in the country, we must do this work.
3. The requirements of packaging for small pipe fittings, such as exports, wooden boxes are needed, about 1 cubic meter; the number of elbows in this box is not more than one ton, the standard allows the suit, that is, the small ones are put in the large ones. However, the total weight cannot generally exceed 1 ton. For large pieces, a single package is required, such as 24", it must be a single package. The other is the package mark which is to indicate the size, steel number, batch number, manufacturer's trademark and so on.
