Butt welding elbow manufacturer

Butt welding elbow manufacturer

Butt welding elbow is one of many kinds of elbow, which has the property of general elbow as well as its own characteristic.

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, the usually production methods of butt welding elbow butt welding and flash butt welding method, the productivity is high, it is easy to realize automation, so has won a wide range of applications. Divided into carbon steel butt welding elbow according to the production of materials, alloy steel and stainless steel butt welding elbow;According to the Angle of the different generally divided into 45 degree butt welding elbow,90 degree butt welding elbow,180 degree butt welding elbow.

90-degree butt welding elbow is a resistance welding method that USES resistance heat to weld two workpieces together along the whole end face at the same time. Butt welding is widely used because of its high productivity and easy automation. Its application range can be summarized as follows:

(1) Connection length of workpiece.

(2) Butt welding of ring workpiece.

(3) Assembly welding of components, simple rolling, forging, stamping or machining parts into complex parts, to reduce the cost.

(4) Butt welding of different metals can save precious metals and improve product performance.

In piping systems, elbows are pipe fittings that change the direction of the piping.According to the Angle points, there are 45° and 90°180° three commonly used, in addition, according to the needs of the project also includes 60° and other abnormal Angle elbow.

Elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metal and plastic, etc.
