Butt welding elbow is one of the many kinds of elbow, it has the nature of general elbow, and also has its own unique nature. Here I will briefly introduce the butt welding elbow.
Elbow is a steel molding or by forging molding elbow, elbow and the connection method is through the use of heat resistance steel pipe butt welding, the two workpiece along the entire face and welding, butt welding elbow production methods usually have butt welding and flash butt welding of 2 kinds of methods, high productivity, easy to to achieve automation, so has been widely used. Butt welding elbow according to the production of different materials are divided into carbon steel, alloy steel and stainless steel butt welding elbow; according to the angle of difference, generally divided into 45 degrees butt welding elbow, 90 degree butt welding elbow, 180 degree butt welding elbow, etc..
Pipeline elbow elbow is installed in a commonly used connection pipe for the pipe bend connection. Production methods can be divided into push bend, bend, bend, stamping forging casting elbow. Makes the standard can be divided into water, electricity standard, GB, DIN, and American Standard Japan, Russia standard etc.. Other name: 90 degree elbow, right angle bend, love bend and so on. Use: connect two nominal diameter same pipe, make pipeline make angle turn. Carbon steel elbow, cast steel bend, butt welding steel elbow, stainless steel elbow, copper elbow and aluminium alloy elbow are classified by material. Elbow can be said to cover the use of all walks of life in the country, small to the family, large enterprises.
The butt welding elbow is a kind of resistance welding method which uses the resistance heat to weld the two workpieces along the whole end surface simultaneously. Butt welding is widely used because of its high productivity and easy automation. Its scope of application can be summarized as follows:
(1) the length of the workpiece.
(2) butt welding of annular workpiece.
(3) assembly welding of components, to weld the simple rolling, forging, stamping or machining parts into complex parts to reduce the cost.
(4) the butt welding of dissimilar metals can save precious metals and improve the performance of products.
