Groove elbow

The groove elbow is a kind of pipe fittings commonly used in water heating installation. It is used to connect the bend of the pipe and change the direction of the pipe.

Other names: 90 degree groove elbow, right angle elbow, love elbow, punch groove elbow, pressing groove elbow, mechanism groove elbow, welding groove elbow, etc.

Usage: Connecting two pipes of the same nominal diameter or different, making the pipes turn at 90, 45, 180 and various degrees.

The bending radius is less than or equal to 1.5 times the diameter of the pipe, which belongs to the groove elbow, which is 1.5 times larger than the pipe diameter and belongs to the elbow.

A kind of pipe fittings commonly used in pipeline installation, connecting two pipes of the same nominal diameter or different, so that the pipe bends at a certain angle, nominal pressure is 1-1.6 Mpa.

1. Because most of the pipe fittings are used for welding, in order to improve the welding quality, the end of the car groove, leaving a certain angle, with a certain edge, this requirement is also more stringent, the edge is thicker, the angle is how many and the deviation range are stipulated. The surface quality and mechanical properties are basically the same as those of pipes. For the convenience of welding, the fittings of the pipe and the connected pipe are the same.

2. All the pipe fittings should be treated by surface treatment. The oxide scale on the inner and outer surfaces should be sprayed off by shot peening and then coated with anticorrosive paint. This is for the export needs, and also for the convenience of transportation in China to prevent corrosion and oxidation, we must do this work.

3. The requirement for packing is that small pipes, such as export, need to be made into wooden boxes, about 1 cubic metre, stipulating that the number of groove elbows in such boxes can not exceed about one ton, the standard allows the package, that is, large and small, but the total weight can not exceed 1 ton. For large y, a single package is required, like 24 "for a single package. Another is the packaging mark, marking is the size, the steel number, the batch number, the manufacturer trademark and so on.
