Hot Rolled Carbon Steel Seamless Pipe

The most extensively employed punching machine for seamless steel pipe or seamless steel tube is cone-shaped roller puncher, featuring higher production efficiency, fantastic product good quality and massive hole enlargement. It might punch several different steels. Just after punching, round billet will undergo successively skew rolling, continuous rolling and extruding by three-roller. After extruding, it should be detached for sizing.

The material for rolled seamless steel tube is round pipe billet. This round billet is usually cut into billet material together with the length of one meter by cutting machines. Then it really is conveyed for the smelting furnace for heating remedy with all the temperature of 16
00. We use hydrogen or acetylene as fuel. It really is essential to handle the temperature inside the furnace. After heat therapy, round billets is going to be punched by pressure punching machine.
The sizing mill rotates in high speed into seamless steel pipes to punch holes by way of tapered bit. The inside diameter of seamless steel tube is determined by the length of outside diameter of drill bit of sizing mill. Just after sizing, steel tube enters the cooling tower for spray cooling. Right after cooling, pipes might be straightened.
Immediately after straightening, seamless steel pipes are sent by conveyor belt for the metal inspection machine for internal inspection. If you can find cracks and air bubbles inside the pipe, they are going to be discovered out. Right after high quality testing, steel pipes ought to undergo hand sorting. We use paint to spray quantity, specification and batch number. Then they may be sent towards the warehouse by crane.
