The way the seamless elbow is constructed

There are multiple manufacturing processes for seamless elbow forming, seamless elbow, butt welding elbow, carbon steel elbow, alloy elbow, stainless steel elbow and so on. The company has many years of manufacturing experience and export, our company simply help you introduce the seamless elbow manufacturing technology and process forming,

Seamless elbow is one of the pipe fittings using the production technology is not the same, and it is divided into hot rolled (kneading) seamless elbow fittings and cold drawn (rolling) seamless elbow fittings. Cold drawn (rolled) pipe is divided into round pipe and irregular pipe two kinds.

The material of rolled seamless elbow pipe fittings is round pipe blank, round pipe embryo should be cut and processed into blank with a growth degree of about one meter, and sent to the furnace by conveyor belt for heating. The billet is fed into a furnace and heated to about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Temperature control in the furnace is the key question. After the round tube billet comes out, it must pass through the pressure punch. Usually the most common perforator is the conical roll perforator. This perforator has high production efficiency, good quality of seamless elbow products, large perforation size, and can wear a variety of pipe fittings. After perforation, the round tube blank is successively rolled by three rollers, continuous rolling or kneading. After kneading, remove the tube and determine the diameter. The sizing machine rotates the steel embryo through the conical drill at high speed to punch holes to form pipe fittings.

Seamless elbow pipe fittings manufacturers mainly produce a variety of different models and materials of pipe fittings products, welcome the need of users to consult and order!
