Quality 90D Elbow LR manufacturers tell you that a pipe fitting is commonly used in pipeline installation to connect two pipes with the same or different nominal diameters. Quality 90D Elbow LR manufacturers tell you that it makes the pipeline turn at a certain angle, and the nominal pressure is 1-1.6Mpa.

Skills requirement. 1. Quality 90D Elbow LR manufacturers tell you that since most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are beveled, with a certain angle and a certain edge. This requirement is also relatively strict. How thick, how much the angle is and the deviation range are stipulated. The surface quality and mechanical properties are basically the same as the pipe. For the convenience of welding, the steel grade of the pipe fittings and the pipes to be connected is the same.
2. Quality 90D Elbow LR manufacturers tell you that all pipe fittings must undergo surface treatment, and the iron oxide scale on the inner and outer surfaces is sprayed off by shot blasting, and then coated with anti-corrosion paint. This is for export needs, and moreover, domestically, it is also for the convenience of transportation to prevent rust and oxidation, and work in this area must be done.
3. Quality 90D Elbow LR manufacturers tell you that is the requirement for packaging. For small pipe fittings, such as export, you need to make a wooden box, of about 1 cubic meter. It is stipulated that the number of elbows in this box should not exceed one ton. These standard sets are allowed, that is, large sets are small, but the total weight generally cannot exceed 1 ton. For large pieces y, they must be packaged individually, such as 24″, they must be packaged individually. In addition, there are packaging marks, which must indicate the size, steel number, batch number, manufacturer’s trademark, etc.
