ASTM/UNS N02200 60 degree Butt Welding Elbow S/R DN40 SCH80 Alloy Steel Pipe Fitting

Introduction elbow

In the pipeline system, elbow is a pipe fitting that changes the direction of the pipeline. According to the angle, there are three most commonly used elbows: 45 ° and 90 ° 180 °, and other abnormal angle elbows such as 60 ° are also included according to the needs of the project. Elbow materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics.

The connection methods with pipes include: direct welding (the most commonly used method) flange connection, hot-melt connection, electric fusion connection, threaded connection and socket connection. According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow, etc. Other names: 90 degree elbow, right angle bend, etc.

Purpose 

German standard elbow

German standard elbow

A connecting pipe fitting commonly used in pipeline installation, which connects two pipes with the same or different nominal diameter to make the pipeline turn at a certain angle, and the nominal pressure is 1-1.6mpa

Technical Requirement

1. Since most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are turned into grooves, with a certain angle and a certain edge. This requirement is also strict. There are regulations on the thickness of the edge, 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 pipe fittings and connected pipes is the same.

2. That is, all pipe fittings shall be subject to surface treatment, and the iron oxide scale on the internal and external surfaces shall be sprayed off by shot peening, and then coated with anti-corrosion paint. This is for export needs. Moreover, in China, it is also to facilitate transportation and prevent corrosion and oxidation.

3. That is, the requirements for packaging. For small pipe fittings, such as export, wooden boxes need to be made, about 1 cubic meter. It is stipulated that the number of elbows in such boxes can not exceed 1 ton. The standard allows suits, that is, large sets and small sets, but the total weight can not exceed 1 ton. For large pieces y, a single package is required. For 24 ", a single package is required. Another is the packaging mark, which should indicate the size, steel number, batch number, manufacturer's trademark, etc
