A860alloy steel elbow carbon-steel-elbow90degree
Introduction
Elbow is a kind of pipe fittings commonly used in plumbing installation, which is used to connect at the bend of pipe and to change the direction of pipe.
Other names :90 elbow, right angle bend, love bend, punching elbow, pressing elbow, mechanism elbow, welding elbow, etc.
Purpose: Connect two pipes with the same nominal diameter or different diameter so that the pipes can be turned 90,45,180 and various degrees.
The bending radius is less than 1.5 times of the diameter of the pipe, and 1.5 times of the diameter of the pipe belongs to the elbow.
Folding Purpose
A pipe fitting commonly used in pipe installation to connect two pipes with the same or different nominal diameter to make a certain angle turn, nominal pressure of 1-1.6 Mpa.
Technical requirements for folding
1. because most of the pipe fittings are used for welding, in order to improve the welding quality, the end part is groove, leaving a certain angle, with a certain edge, this requirement is also more strict, how thick the edge, how much angle and deviation range are stipulated. The surface quality and mechanical properties are basically the same as the pipe. For the convenience of welding, the pipe fittings are the same as the steel type of the connected pipe.
2., all pipe fittings must be surface treated, the internal and external surface of the oxide sheet through shot peening treatment, and then coated with anticorrosive paint. This is for export needs, moreover, in the domestic is also to facilitate transportation to prevent corrosion and oxidation, to do this work.
3. is the requirement of packing for small pipe fittings, such as export, need to make wooden cases, about 1 cubic meter, the number of bends in this box should not exceed one ton, this standard allows suits, that is, large sets and small ones. But the total weight should not exceed 1 ton. For large y, a single package, such as 24" must be a single package. Also is the packing mark, the mark is to indicate the size, the steel number, the batch number, the factory trademark and so on.
