ASTM/UNS N02200 90 degree Butt Welding Elbow S/R DN80 SCH80 Alloy Steel Pipe Fitting

Introduction to 90 degree elbow

Product overview: 90 degree elbow is the main product of Hebei Shengze pipe fittings manufacturing Co., Ltd. the materials of 90 degree elbow include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics Direct welding (the most common way) flange connection, thread connection and socket connection are used to connect with the pipe

Intuitively, the short radius elbow is much shorter than the long radius elbow, and the bending radius of the elbow is very fast. Long radius elbow is the most commonly used, and it is also long radius by default. Long radius elbow will be used where the pressure or flow rate is high. If the resistance requirements of solid transmission pipeline are strict, larger radius elbow shall be used. Short radius is generally used in low-pressure fluid or where elbows are limited. If there are no restrictions or not indicated in the contract, the long radius elbow is preferred

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
