Elbow For Fire Pipe Fittings
Elbow is a pipe fitting that changes the direction of the line.According to the Angle, there are 45° and 90°180° three most commonly used, in addition, according to the engineering needs to include 60° and other abnormal Angle bend.Elbow materials are cast iron, stainless steel, alloy steel, malleable iron, carbon steel, nonferrous metals and plastics.The method of connection with pipe is: direct welding (the most common way) flange connection, hot welding connection, electric welding connection, threaded connection and socket connection.According to the production process can be divided into: welding elbow, stamping elbow, push bending, casting elbow, butt welding elbow.Other names :90 degree bend, right Angle bend, love bend, etc.Elbow is a kind of pipe fitting commonly used in plumbing installation. It is used to connect the pipe at the bend and change the direction of the pipe.
Other names :90° bend, right Angle bend, love bend, stamping bend, pressing bend, mechanism bend, welding bend, etc.
Purpose: connect two pipes with the same or different nominal sizes to make the pipe turn at 90°, 45°, 180° and various degrees.
Bending radius less than or equal to 1.5 times of the pipe diameter belongs to the elbow, greater than 1.5 times of the pipe diameter belongs to the elbow.
A pipe fitting commonly used in pipeline installation is used to connect two pipes of the same or different nominal sizes to make the pipe turn at a certain Angle and the nominal pressure is 1-1.6mpa.
1. As most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are turned into a groove, with a certain Angle and a certain edge. This requirement is also strict.The surface quality and mechanical properties are basically the same as the pipe.For the convenience of welding, the pipe fitting is of the same type of steel as the pipe being connected.
2, is that all the pipe fittings have to go through the surface treatment, the inside and outside of the surface of the iron oxide through peening treatment spray off, and then coated with anti-corrosion paint.This is for export needs, moreover, in the domestic is also to facilitate transportation to prevent corrosion and oxidation, we should do this work.
3, it is to the requirement of packing for small pipe fitting, such as export, you need to make a wooden case, about 1 cubic meter, the number of elbow in this kind of box is about not more than a ton, the standard allows a suit, namely big set small, but the total weight is generally not more than 1 ton.For large pieces y you need a single package, like 24 "you need a single package.Additional it is packing mark, mark is to want to indicate dimension, steel number, batch number, manufacturer trademark to wait.

1. According to the production method, it can be divided into pushing, pressing, forging, casting, etc.
2. According to the manufacturing standard, it can be divided into national standard, electric standard, ship standard, chemical standard, water standard, American standard, German standard, Japanese standard and Russian standard.
3. According to its radius of curvature, it can be divided into long radius elbow and short radius elbow.Long radius elbow refers to the outer diameter of the pipe whose radius of curvature is equal to 1.5 times, that is, R=1.5D;Short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R= 1.0d.(D is the diameter of the elbow, and R is the radius of curvature).
4. According to the pressure levels, there are about 17 types, which are the same as the American pipe standards, including Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s and XS.Sch80, SCH100, Sch120, Sch140, Sch160, XXS;The two most commonly used are STD and XS.
5. According to the different shapes of the purposes can be divided into: groove bend, sleeve bend, double bearing bend, flange bend, reducing bend, stand bend, internal and external tooth bend, stamping bend, push bend, socket bend, butt welding bend, inner wire bend, etc.
