In the pipeline system, the elbow is a pipe fitting that changes the direction of the pipeline. According to the angle, there are three commonly used elbows of 45° and 90°180°, and other abnormal angle elbows such as 60° are also included according to engineering needs. The elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. The ways to connect with the pipe are: direct welding (the most common way) flange connection, hot melt connection, electrofusion connection, threaded connection and socket connection, etc. According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow, etc. Other names: 90 degree elbow, right angle bend, love and bend, etc.

Seamless elbow is a kind of pipe fittings used for pipe turning. Among all the pipe fittings used in the piping system, the proportion is about 80%. Generally, different forming processes are selected for elbows with different materials and wall thicknesses. Currently. Commonly used seamless elbow forming processes in manufacturing plants include hot pushing, stamping, extrusion, etc.

Seamless elbows are also called seamless steel pipe elbows. Because of their different manufacturing processes, seamless elbow fittings are divided into hot-rolled (extruded) seamless elbow fittings and cold drawn (rolled) seamless elbow fittings. . Cold drawn (rolled) tubes are divided into two types: round tubes and special-shaped tubes.

The raw material for rolling seamless elbow fittings is round tube blanks. The round tube blanks are cut by a cutting machine into a billet with a length of about one meter and sent to the furnace for heating via a conveyor belt. The billet is fed into the furnace and heated at a temperature of approximately 1200 degrees Celsius. The fuel is hydrogen qi or acetylene. The temperature control in the furnace is a key issue. After the round billet is out of the furnace, it must be pierced through a pressure punching machine. Generally, the more common piercing machine is a tapered roller piercing machine. This type of piercing machine has high production efficiency, good product quality, large perforation diameter expansion, and can wear a variety of pipe fittings. After piercing, the round tube billet is cross-rolled, continuous-rolled or squeezed by three rolls one after another. After squeezing, take off the tube and calibrate. The sizing machine uses a conical drill bit to rotate at a high speed into the steel blank to punch holes to form pipe fittings.
