Is numerical control api 5l pipe dimensions cutting good

Standard:API 5L PSL1|PSL2.
Scope:API 5L is generally refers to the standards of pipeline steel, include pipeline pipe and pipeline steel plate.
API 5L line pipe steel grade levels:GR. B, X42, X46 and X52, X56, X60, X70 and X80.
Details

Oxygen (O) is a harmful element in steel such as api 5l pipe dimensions. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.

The high strength of api 5l pipe dimensions pipeline steel requires high yield strength of pipeline steel, so that better economic benefits can be obtained. For pipeline steels with bainite type above grade X65, the Bauschinger effect due to the pipe making process will be weakened.

Adhere to the spirit of quality first and user foremost, carry out maintenance and other work according to the requirements of the buyer's contract, and ensure that the engineering project and product after-sales play their application effectiveness. Our company guarantees to carry out self inspection and self supervision according to the quality management policy proposed by our company, and deliver a high-grade, perfect and excellent system engineering to users.

Expression method of pressure coefficient of seamless steel pipe: pressure P 17.5, coefficient S-4 seamless pipe production and manufacturing: tube blank -- Inspection -- peeling -- Inspection -- Heating -- perforation -- pickling -- grinding -- lubrication and air drying -- welding head -- cold drawing -- solution treatment -- pickling -- pickling and passivation -- Inspection -- cold rolling -- degreasing -- air drying -- internal polishing -- one external polishing -- Inspection -- identification of finished api 5l pipe dimensions product packaging.
