Thick-walled steel pipes are mainly used in pipeline transportation and can be used to transport some liquids, for example, some electric energy, crude oil, and some surface water transportation, which can all be completed with the help of thick-walled steel pipes. In modern society, thick-walled steel pipes The application industry and scope of the 16Mn thick-walled steel pipe is once again the main use is very common. Thick-walled steel pipes for general main purposes are cold-rolled from ordinary carbon steel, low-alloy tool steel or alloy tool steel, and have a large amount of processing. They are mainly used as pipelines or structural parts for transporting liquids. Thick-walled steel pipes made of this type of steel are widely used. It is used in every field such as metal briquetting machine, high pressure gas cylinder, boiler, organic fertilizer machinery and equipment, petroleum cracking, automobile half-shaft sleeve, diesel engine and so on.
The raw material for rolling seamless tubes is a round tube blank, which is cut by a cutting machine into a billet with a length of about 1 meter, and sent to a furnace for heating through a conveyor belt. The billets are fed into the furnace and heated at about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Furnace temperature control is a critical issue. After the round tube blank is released, it will be perforated by a pressure perforator. Generally, the more common punching machine is the conical roller punching machine. This kind of punching machine has high production efficiency, good product quality, large amount of perforation and expansion, and can wear a variety of steel grades.
After perforation, the round tube blank is successively cross-rolled, continuously rolled or extruded by three rolls. After extrusion, the tube should be removed and sizing. The sizing machine rotates into the steel billet at high speed through the conical drill bit to punch holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter of the drill bit of the sizing machine. After the steel pipe is sizing, it enters the cooling tower and is cooled by water spray. After the steel pipe is cooled, it will be straightened.
