Butt welding large carbon steel elbow

Butt welding elbow

Welded elbow is a kind of using steel hot pressing molding, or through the bend forging forming, the connection method is through the elbow with the steel pipe butt welding, using resistance heat two artifacts along the entire face welded together at the same time, usually in the production of butt welding elbow butt welding and flash butt welding machine has two methods, the production efficiency is high, it is easy to realize automation, so has gained wide application, divided into carbon steel butt welding elbow according to the production of materials, alloy steel, stainless steel butt welding elbow, according to different generally divided into 45 degree Angle on the morning of butt welding elbow, butt welding elbow, 90 degrees 180 degrees doohan elbow, etc.

After the completion of welding operation, the elbow should be treated with anti-rust or anti-corrosion according to the actual situation or the pipeline external environment, so as to avoid the elbow being corroded or corroded at the welding place, which will lead to the service life of the elbow.More will improve the performance of butt welding elbow.

Large elbows are mainly used to connect the pipe when it turns, that is, to change the direction of the pipe when it turns outside.

The Angle of the big elbow is generally: 45 degrees, 90 degrees, 180 degrees and other individual angles.

The connection mode of big elbow in the process is: direct welding, flange connection, hot melt connection, electric melt connection, thread connection and socket connection, etc.One of them is the direct welding and flange connection.

Large elbows are divided into long radius elbows and short radius elbows.

The production technology scope of large elbow: push elbow, welding elbow, stamping elbow, casting elbow, butt welding elbow, etc.

The material of big elbow is: carbon steel, alloy steel, stainless steel and so on.

Large elbow is widely used in chemical industry, construction, water supply, drainage, petroleum, heavy industry, refrigeration, sanitation, plumbing, fire protection, electric power, aerospace, shipbuilding and other projects.

Large elbow is a joint pipe fitting commonly used in plumbing installations. It is used for connecting pipe bends and changing the direction of the pipe.Purpose of carbon steel elbow: to connect two pipes with the same or different nominal diameters for turning at 90 degrees, 45 degrees, 180 degrees and various angles.A large bend is defined as one and a half times the diameter of the bend and one and a half times the diameter of the bend.
