A234 WPB Straight seam 90Deg Elbow

In piping systems, a 90 degree Bend is a 90 degree bend that changes the direction of the pipe. According to the Angle, there are 45° and 90°180° three most commonly used, in addition, according to the engineering needs also include 60° and other abnormal Angle elbow. Elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics.

The 90 degree elbow is connected to the pipe in the following ways: direct welding (the most common way) flange connection, hot melt connection, electric melt connection, threaded connection and socket connection. According to the production process can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow and so on. Other names: 90 degree bend, right Angle bend, etc.

Bending radius less than or equal to 1.5 times of pipe diameter belongs to the elbow, greater than 1.5 times of pipe diameter belongs to the bend.

Technical requirement

1. Because most 90-degree elbows are used for welding, in order to improve the quality of welding, the end is bevelled, leaving a certain Angle and a certain edge. This requirement is also strict, and the thickness of the edge, the Angle and the deviation range are specified. The surface quality and mechanical properties are basically the same as the pipe. For easy welding, 90 degree elbows are made of the same steel as the pipe to which they are connected.

2. That is, all 90-degree elbows should be treated by surface treatment. The oxide sheet on the inside and outside surfaces should be sprayed off by shot peening and then coated with anti-corrosion paint. This is for export needs, in addition, in order to facilitate transportation to prevent corrosion and oxidation, we should do this work.

3, is the requirements for packaging for small elbow, such as export, you need to do wooden box, about 1 cubic meter, the provision of this box elbow number about not more than one ton, the standard allows the set, that is, a large set of small, but the total weight can not exceed 1 ton. For large pieces y need to be individually packed, like 24 "must be individually packed. The other is the packaging mark, mark is to indicate the size, steel number, lot number, manufacturer's trademark.
