Elbow in the pipeline system, elbow is a pipe fitting to change the direction of the pipeline. According to the Angle, there are 45° and 90°180° three common, 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 iron, carbon steel, non-ferrous metal and plastic. Connection with the pipe: direct welding (common way) flange connection, hot melt connection, electric welding connection, screw connection and socket connection. According to the production process can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow. Other names: 90 degree bend, right Angle bend, love bend, etc.

Technical requirements for 180 - degree elbows

1. Since most pipe fittings are used for welding, in order to improve the welding quality, the end is beveled with a certain Angle and a certain edge, which is also a strict requirement. There are provisions on how thick the edge is, how much the Angle is and the range of deviation. The surface quality and mechanical properties are basically the same as the pipe. For ease of welding, the fittings are of the same type of steel as the connected pipes.

2. All pipe fittings shall be treated with surface treatment. The iron oxide on the inner and outer surface shall be sprayed with shot peening and then coated with anti-corrosion paint. This is for export needs, in addition, in order to facilitate transportation and prevent corrosion and oxidation at home, we should do this work.

3, it is to the requirement of packaging to small pipe fitting, such as export, need to do wooden cases, about 1 cubic meter, the number of elbow in this kind of box about cannot exceed a ton, the standard allows suit, namely big set small, but total weight cannot exceed 1 ton commonly. Single packing is required for large pieces like 24 ". The other is the packaging mark, mark is to indicate the size, steel number, batch number, manufacturer's trademark and so on.
