2022-08-26
A seamless elbow is a pipe fitting used for pipe bending. Among all the pipe fittings used in the piping system, the proportion is larger, about 80%. Typically, 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 and extrusion.

Seamless elbows are also called seamless elbows or seamless pipe elbows in English. Seamless elbow fittings are divided into hot rolled (extrusion) seamless elbow fittings and cold drawn (rolled) fittings due to different manufacturing processes. ) two seamless elbow fittings. Cold drawn (rolled) tubes are divided into round tubes and special-shaped tubes

Seamless elbows are also known as seamless elbows or seamless pipe elbows in English. Seamless elbow fittings are divided into hot rolled (extrusion) seamless elbow fittings and cold drawn (rolled) fittings due to different manufacturing processes. ) Two kinds of seamless elbow fittings. Cold drawn (rolled) tubes are divided into round tubes and special-shaped tubes.
The raw material of rolling seamless elbow fittings is a round tube blank. The round tube billets are cut into billets about one meter long by a cutting machine and sent to a heating furnace for heating through a conveyor belt. The billet is fed into a furnace and heated at a temperature of about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Temperature control in the furnace is a key issue.
After the round tube blank comes out of the furnace, it must pass through the pressure punching machine to stop the perforation. Common and common piercers are tapered roller piercers. This kind of punching machine has high consumption efficiency, good production quality, and the diameter of the punching hole is enlarged, and it can wear various pipe fittings. After piercing, the round tube billets are sequentially cross-rolled, continuously rolled or extruded by three rolls. After squeezing, remove the tube and sizing. The sizing machine is rotated at high speed into the billet by a conical drill bit to punch holes to form the pipe.
