What is the elbow?

Jun 27, 2019

In a piping system, an elbow is a pipe that changes the direction of the pipe. According to the angle, there are three most commonly used 45° and 90°180°, and other abnormal angle elbows such as 60° are also included according to engineering needs.

Elbow China are made of cast iron, stainless steel, alloy steel, malleable iron, carbon steel, non-ferrous metals and plastics. The way to connect with the pipe is: direct welding, flange connection, hot melt connection, electrofusion connection, screw connection and socket connection. According to the production process, it can be divided into: welding elbow, punching elbow, push elbow, casting elbow, butt weld elbow.

Other names: 90° elbow, right angle bend, love and bend.

Uses: Connect two pipes with the same or different nominal diameters to make the pipeline turn 90°, 45°, 180° and various degrees.

Technical requirements: 1. Since most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are all turned into bevels, leaving a certain angle with a certain edge. This requirement is also stricter, the thickness is thicker, the angle is how much and the range of deviations are specified. The surface quality and mechanical properties are basically the same as the tube. For the convenience of welding, the pipe is the same as the steel of the pipe to be connected.

2. All the pipe fittings must be surface treated, and the iron oxide skin on the inner and outer surfaces is sprayed off by shot peening, and then coated with anticorrosive paint. This is for export needs, and in addition, in order to facilitate transportation and prevent corrosion and oxidation in the country, we must do this work.

3, The requirements for packaging for small pipe fittings, such as exports, you need to do a wooden box, about 1 cubic meter, the number of elbows in this box is not more than one ton, the standard allows the suit, that is, a large set. However, the total weight can not exceed 1 ton. For large pieces, a single package is required, such as 24", it must be a single package. The other is the package mark, the mark is to indicate the size, steel number, batch number, manufacturer's trademark and so on.
