Butt-welding elbow factory

Butt-welding elbow factory

Welded Elbow is a steel elbow that has been hot pressed or forged, and its connection form is to weld the elbow directly to the steel pipe.Butt welding elbow according to its radius of curvature can be divided into long radius butt welding elbow and short radius butt welding elbow;According to the pressure grade, there are about 17 kinds of pipes, which are the same as the American pipe standard, among which STD and XS are commonly used.According to the Angle of the elbow, there are 45 degrees of butt welding elbow, 90 degrees of butt welding elbow and 180 degrees of butt welding elbow and other different angles of the elbow;By materials: carbon steel, alloy steel and stainless steel.

Welded elbow is an elbow made of steel that is hot pressed or forged. The connection form of elbow is to weld directly to steel pipe. The main manufacturing standards of butt-welded elbow are generally GB/T13401-2005, GB/T12459-2005, ASME B16.9, SH3409, HG/T21635, HG/T21631, SY/T0510, GB/T10752-1995.

The company is an experienced large diameter welding elbow manufacturers, the factory team is lean technology, good service attitude.

Carbon steel elbow technology threshold is very high, mainly rely on imports.From the technical sources of the company, the possibility of success of the elbow is higher.These technical bottlenecks will restrict the long-term profitability of the whole industry and the ability to participate in competition.In order to carbon steel elbow because of heating and eyeglass erosion, welding current should not be too large, less than about 20% carbon steel electrode, arc should not be too long, fast cooling between layers, with narrow weld bead is appropriate.

It has become one of the most widely used pipe fittings, occupying about 80% of the world market.

Butt-welding elbow is a kind of elbow that can improve the temperature of thermal insulation. It is widely used in construction, decoration and pipeline laying. It can ensure the normal and unobstructed pipeline.

The common Angle of butt welding elbow is 45°, 90° 180° three kinds of elbow.The production method of elbow is push elbow, stamping elbow, extrusion elbow, butt-welding elbow, etc.

The role of butt welding elbow is to connect the same and different pipe nominal diameter, is the pipe to do a certain turn.
