Methods of preparation and classification of carbon steel pipes

Preparation of carbon steel pipe

 

The raw material for carbon steel pipe is a round pipe billet, which is cut by a cutting machine into billets of approximately 1 metre in length and heated by a conveyor belt to the furnace. The billets are heated in the furnace at a temperature of approximately 1200 degrees Celsius. The fuel is hydrogen or acetylene. Temperature control in the furnace is a key issue. After the round billets are discharged from the furnace they are hollowed out by a pressure perforating machine. The more common perforating machine is the conical roller perforating machine, which has high production efficiency, good product quality, large perforation and expansion capacity and can perforate a variety of steel grades. After perforation, the round pipe billet has been three rolls of oblique rolling, continuous rolling or extrusion. After extrusion, the tube should be sized. The sizing machine rotates the conical drill bit into the steel embryo at high speed to form the steel pipe. carbon steel pipe inner diameter is determined by the length of the outer diameter of the sizing machine drill bit. After sizing, the steel pipe enters the cooling tower and is cooled by spraying water, after which it is straightened. After straightening, the steel pipe is sent by conveyor belt to the metal flaw detector (or hydraulic test) for internal flaw detection. If there are cracks, bubbles and other problems inside the steel pipe, they will be detected. After quality inspection, the steel pipe is selected by strict hand selection. carbon steel pipe is then sprayed with paint with number, specification, production batch number, etc. and lifted by crane into the warehouse. The pipe is then lifted by crane into the warehouse.

Classification of carbon steel pipe

 

Carbon steel pipe is divided into two categories: hot-rolled and cold-rolled (drawn) steel pipe. Hot-rolled carbon steel pipe is divided into general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, geological steel pipe and other steel pipe, etc.. Cold rolled (dial) carbon steel pipe in addition to general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, other steel pipe, but also includes carbon thin-walled steel pipe, alloy thin-walled steel pipe, stainless thin-walled steel pipe, shaped steel pipe. The outer diameter of hot rolled seamless pipe is generally greater than 32mm, wall thickness 2.5-75mm, cold rolled seamless steel pipe outer diameter can be up to 6mm, wall thickness can be up to 0.25mm, thin wall pipe outer diameter can be up to 5mm, wall thickness less than 0.25mm, cold rolled than hot rolled dimensional accuracy.
