15X5M ASME B16.9 45 Degree Long Radius Bend Alloy Steel With Beveled Ends

An elbow is a pipe fitting that changes the direction of a pipe.

According to the angle, there are 45 ° and 90 ° 180 ° three most commonly used, in addition, according to the needs of the project, it also includes 60 ° and other abnormal angle elbows.

Elbow materials are stainless steel, alloy steel, carbon steel and so on.

Technical requirement:

1. As most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are chamfered with a certain angle and a certain edge. This requirement is also relatively strict. The thickness of the side, the angle and the deviation range are specified. The surface quality and mechanical properties are basically the same as the pipe. For the convenience of welding, the steel grade of pipe fittings and connected pipes is the same.

2. That is to say, all the pipe fittings have to undergo surface treatment. The oxide scales on the inner and outer surfaces are sprayed off by shot peening, and then coated with anti-corrosion paint. This is for export.

3. It is the requirement for packaging. For small pipe fittings, such as export, wooden cases should be made, about 1 cubic meter. It is stipulated that the number of elbows in such cases should not exceed one ton. The standard allows for suits, that is, large sets of small ones, but the total weight should not exceed 1 ton. For large pieces of Y, they need to be packed individually, while those of 24 "must be packed individually. In addition, it is the packaging mark, which should indicate the size, steel grade, batch number, manufacturer's trademark, etc.
