Elbow elbow is a kind of many types, the general nature of the elbow, but also has its own unique properties. Here I'll brief you on the 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. Elbow according to different production materials for carbon steel, alloy steel and stainless steel elbow; according to the different general angle is 45 degree elbow, 90 degree elbow, 180 degree elbow etc..
90 degree elbow is a kind of resistance welding method using heat resistance two workpiece along the entire face and welded together. Butt welding of high productivity, easy to realize automation, so it has been widely applied. The scope of application can be summarized as follows:
(1) the.
(2) butt welding of circular workpiece.
(3) components of the welding, simple rolling, forging, stamping and machining parts welded into complex parts, in order to reduce the cost.
(4) butt welding of dissimilar metals can save precious metals, improve product performance.
Large diameter welded elbow in the welding operation is completed according to the actual situation of the external environment or pipeline rust or corrosion treatment, in order to avoid the elbow in the weld corrosion or corrosion, caused by the short life-span of elbow.
