MS Seamless Pipe, Mild Steel Seamless Pipe Manufacturer & Exporter
Mild Steel (MS) pipes are manufactured using low carbon (less than 0.25%) steel. As MS Pipes are made from mild steel they can easily be welded and formed in various shapes and sizes for pipelining and tubing purposes.
Permanent Steel Manufacturing Co., Ltd is a well-known MS Seamless Pipe Manufacturer, known for its precision engineering, light weight, corrosion resistance, reasonable structure, complex details, and economy. We have set an example in terms of quality and performance by manufacturing and supplying MS seamless pipes. MS seamless pipes are due to their high strength and pressure-bearing capacity.It is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycle frames, and steel scaffolding used in construction.
Mild steel Seamless pipe is a capillary tube made of steel ingots or solid tube billets through perforation, and then hot-rolled, cold-rolled or cold-rolled. Seamless carbon steel pipe has an important position in my country's steel pipe industry.
Manufacturing process:The raw material of the seamless mild steel pipe is a round tube blank. The round tube blank is cut by a cutting machine into a billet with a length of about 1 meter, and is sent to the furnace for heating via a conveyor belt. The billet is fed into the furnace and heated at a temperature of approximately 1200 degrees Celsius. The fuel is hydrogen or acetylene. The temperature control in the furnace is a key issue.
Low carbon steel tubing with seamless(ms seamless pipe) has a large tendency to aging, both quenching and aging tendencies, as well as deformation and aging tendencies. When the steel is cooled from high temperature, the carbon and nitrogen in the ferrite are supersaturated, and the carbon and nitrogen in the iron can be slowly formed at normal temperature, so that the strength and hardness of the steel are improved, and the ductility and toughness are lowered. This phenomenon is called quenching aging. Low carbon steel tubing with seamless will have an aging effect even if it is not quenched. The deformation of low carbon steel tubing with seamless produces a large number of dislocations. The carbon and nitrogen atoms in the ferrite interact elastically with dislocations, and carbon and nitrogen atoms gather around the dislocation lines. This combination of carbon and nitrogen atoms and dislocation lines is called the Cochrane gas mass (Kelly gas mass). It increases the strength and hardness of steel and reduces the ductility and toughness. This phenomenon is called deformation aging. Deformation aging is more harmful to the ductility and toughness of low carbon steel than quenching aging.
There are obvious upper and lower yield points on the tensile curve of low carbon steel. From the upper yield point until the end of the yield extension, a surface wrinkle band formed on the surface of the sample due to uneven deformation is called the Rydes belt. Many stamping parts are often scrapped. There are two ways to prevent it. A high pre-deformation method, the pre-deformed steel is placed for a period of time and the Rudes belt is also produced when stamping, so the pre-deformed steel should not be placed too long before stamping. The other is to add aluminum or titanium to the steel to form a stable compound with nitrogen to prevent deformation aging caused by the formation of Kodak air mass.
