The elbow in the pipe system is a pipe fitting that changes the direction of the pipe.According to the Angle points, there are 45° and 90° 180° three commonly used, in addition, according to the needs of the project also includes 60° and other abnormal Angle elbow.Elbow material is stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metal and plastic, etc.The ways of connecting with pipe are: direct welding (common way) flange connection, hot melt connection, electric melt connection, thread connection and socket connection, etc.According to the production process can be divided into: welding elbow, push elbow, stamping elbow, casting elbow, butt welding elbow, etc.

The elbow saves space and, more importantly, ensures that the joint does not leak and has a good sealing performance.The reduction in the size of the compact flange is due to the reduction in the diameter of the sealing element, which will reduce the cross section of the sealing surface.Secondly, the flange gasket has been replaced by a sealing ring to ensure that the sealing face matches the sealing surface.The B value of the 45 degree elbow is the structural size, which is mainly for the convenience of pipe designers.

Stamping elbow is the earliest application in the mass production of seamless elbow forming technology, in the common specifications of elbow production has been heat push method or other forming technology to replace, but in some specifications of elbow due to the production of less, too thick or too thin wall.

Products are still in use when there are special requirements.The elbow is formed by the tube blank with the same outer diameter as the elbow, which is directly pressed in the die by the press.Before stamping, the tube blank is placed on the lower die, the inner core and end die are loaded into the tube blank, the upper die moves downward and begins to be pressed, and the elbow is formed by the constraint of the outer die and the support of the inner die.Compared with thermal pushing process, the appearance quality of stamping forming is not as good as the former.The outer arc of the stamping elbow is in the state of stretching when forming, and there is no excess metal in other parts to compensate, so the wall thickness at the outer arc is reduced by about 10%.However, because it is suitable for single piece production and low cost, the stamping elbow process is mostly used in the manufacturing of small batch and thick wall elbow.

Stamping elbow is divided into cold stamping and hot stamping, usually according to the nature of the material and equipment capacity to choose cold stamping or hot stamping.
