Classification and process of seamless elbow fittings  

Seamless elbow, also known as Seamless Elbow or Seamless pipe Elbow, is divided into hot rolled (extruded) seamless elbow and cold drawn (rolled) seamless elbow, depending on the manufacturing process.  Cold-drawn (rolled) pipe is divided into circular pipe and special-shaped pipe two kinds.  

The raw material for rolling seamless elbow pipe fittings is round tube blank. The round tube embryo is cut and processed by the cutting machine with a length of about one meter, and sent to the furnace for heating by conveyor belt.  The billet is fed into a furnace to be heated at about 1200 degrees Celsius.  The fuel is hydrogen or acetylene.  The temperature control in furnace is the key problem.  After the round tube billet comes out of the oven, it must go through the pressure punch.  The most common puncher is the cone roll puncher, which has high production efficiency, good product quality, large perforation and diameter expansion, and can wear a variety of pipe fittings.  After perforation, the round tube is successively rolled by three rolls, cross - rolled, or extruded.  After extrusion, take off the pipe and size.  The sizing machine spins into the steel embryo through the conical drill bit at high speed to drill holes and form pipe fittings.  

Seamless elbows do not cause corrosion, pitting, rust or wear.  Stainless steel is one of the materials with high strength in building metal materials.  Due to its excellent corrosion resistance, stainless steel enables structural components to maintain the integrity of their engineering design.  The raw material for rolling seamless elbow pipe fittings is round tube blank.
