Elbow is to change the direction of pipe fittings. According to the angle, there are 45掳 and 90掳180掳 three kinds of most commonly used, in addition to engineering needs also include 60掳 and other non-standard angle elbow. Elbow materials are cast iron, stainless steel, alloy steel, can be calcined cast iron, carbon steel, non-ferrous metals and plastics. The way to connect with the pipe is: direct welding (the most commonly used) flange connection, Elbow Hot melt connection, electric fusion connection, Elbow thread connection and socket type connection, etc. According to the production process can be divided into: welding elbow, stamping elbow, push elbow, casting elbow and so on. Other name: 90 degrees elbow, right angle bend, love and bend, etc.

Elbow in the pipeline what role, Elbow belongs to pipe fittings, elbow used in the pipeline in order to change the pipeline, in the pipe bend is with elbow, so as to change the direction of the pipeline, according to the angle of 15 degrees elbow, 30 degrees elbow, 45 degrees elbow, 60 degrees 90 degrees elbow, 180 degree elbow, this is the most commonly used elbow angle, this need according to the construction site installation needs, Elbow to order the production of elbow, material can be divided into stainless steel elbow and carbon steel elbow and alloy steel elbow, The connection of elbows and pipes is welded by means of welding, so the general elbow in order to facilitate the welding, Elbow push into the type, and then in the plastic, elbow after the completion of the type, still need the car mouth, the mouth is to facilitate the welding, the connection of the elbow to see the needs of the project and the use of flange connection, elbow at both ends with flange, to the construction site directly installed on it, flange connection not only the sealing surface performance is good, and disassembly is very convenient, thread connection, is the silk buckle elbow, and wire pipe fittings or other equipment, To the construction site directly installed on it, but the wire buckle elbow is usually small-caliber low pressure elbow, using wire buckle connection,

Large-caliber high-pressure elbow is welded or flange connection method. The elbow is in the piping system and is used to change the pipe direction.

Elbow, pipe installation commonly used in a connection with pipe fittings, connecting two nominal diameter of the same or different pipe, so that the pipe to make a certain angle turn. The bending radius is less than 1.5 times times the diameter of the pipe is the elbow, more than 1.5 times times the pipe diameter belongs to the bend pipe. Elbow According to the angle, there are 45掳 and 90掳180掳 three kinds of most commonly used, in addition to engineering needs also include 60掳 and other non-standard angle elbow. Elbow materials are cast iron, stainless steel, alloy steel, malleable iron, carbon steel, non-ferrous metals and plastics.
