How to detect seamless elbow pipe fitting products

Our company mainly produces a variety of different angles and models of seamless elbow pipe fittings, seamless elbow pipe fittings are mainly used for pipe installation in the turning point of a pipe, in the pipeline system using different angles and different connection methods, generally commonly used Angle is divided into 45 degrees, 90 degrees, 180 degrees. And customers need 60 degrees and different angles of elbow products, different connection methods are commonly used: direct welding, flange connection, hot melt connection and other common connection methods.

Seamless elbow pipe is one of the pipe, and cold drawn seamless seamless elbow bend pipe two kinds, including cold drawn seamless elbow is divided into circular tube and special-shaped tube two kinds, fine forging method of forming method, used in forging forging machine to the pipe end or washed out and reduce outside light, common type rotary forging machine, connecting rod type, roller type, etc.

Rolling method: rolling, suitable for thick wall tube inner round edge. In general, a core is placed in the tube without a mandrel, and a roller is used to push and press around the tube. In the stamping method, a taper core is used to expand the tube end to the required size and shape on the punch press. Bending forming method: In the bending forming method, there are usually 3-4 rollers, two fixed rollers, one adjustment roller, and the fixed roller distance is adjusted.

Seamless elbow pipe fittings are made by the commonly used manufacturing method. The current advanced way is to push the shape directly. This forming method is now more common than the method of making technology, also using the bulging method: there are two ways of bulging method: one is placed in the tube rubber, with punch above the tightening, so that the tube protruding form; Another method is to punch the desired liquid into the tube and apply the pressure of the liquid to drum the tube into the desired shape. In the manufacture of seamless elbow pipe fittings according to customer requirements adopt different manufacturing process processing molding.
