The introduction of elbow

In piping systems, an elbow is a pipe fitting that changes the direction of the pipe.According to the Angle, there are 45° and 90°180° three commonly used, and according to the engineering needs, there are also 60° and other abnormal Angle elbows.Elbow materials include cast iron, stainless steel, alloy steel, malleable iron, carbon steel, nonferrous metal and plastic, etc.

There are direct welding (commonly used) flange connection, hot melt connection, electric fusion connection, threaded connection and socket connection, etc.According to the production process can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, welding carbon steel elbow how to make the comparison standard

Carbon steel elbow manufacturing standards: national standard, American standard, Japanese standard, German standard, Russian standard.The wear of GB elbow has always been a factor affecting the production of civilization, with the continuous development of science and technology, and continuous innovation.Cast stone, cast steel, welding and other materials have appeared.

Hot push bend deformation characteristics is depending on the rules of the metal material volume before and after plastic shaped pipe diameter, concluded that chooses the pipe diameter less than bend diameter, through core clubs of billet deformation process, the arc was tight spot metal activity, counter to other parts of the thinned by expanding, then get the wall thickness of the elbow.The forging press should have good rigidity, and the movable beam and piston should have good guiding accuracy to ensure the precision of the forging.

The application range of butt welding, butt welding is widely used because of its high production efficiency and easy automation.Manufacturer commonly used seamless elbow forming process are hot push, stamping, extrusion and so on.Seamless elbow has long service life.Elbow, etc.Other names: 90 degree bend, right Angle bend, etc.
