Type: Seamless steel pipe
Material: Carbon Steel
Processing type: Forging
Use: Well Drilling
Seamless steel pipe is a steel pipe made by piercing a whole round steel without any weld on the surface, which is called a seamless steel pipe. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, coldrolled seamless steel pipes, cold drawn seamless steel pipes, extruded seamless steel pipes, top pipes, etc. According to the cross-sectional shape, seamless steel pipes are divided into two types: circular and irregular. Irregular pipes include square, elliptical, triangular, hexagonal, melon seed shaped, star shaped, and winged pipes with various complex shapes. The maximum diameter is 900mm and the minimum diameter is 4mm. According to different purposes, there are thick walled seamless steel pipes and thin-walled seamless steel pipes. Seamless steel pipes are mainly used as drilling pipes for petroleum geology, cracking pipes for petrochemicals, boiler pipes, bearing pipes, as well as high-precision structural steel pipes for automobiles, tractors, and aviation..
• Machinery manufacturing: seamless steel pipes are used to manufacture mechanical structures and hydraulic equipment, which can save machining man-hours, improve material utilization and product quality.
• Geological drilling: seamless steel pipes for geological drilling are important tools for core drilling, including drill pipes, drill collars, core pipes, etc
• Fluid transportation: Seamless steel pipes are widely used to transport water, oil, gas and other fluids to ensure the safe transportation of fluids
• Petrochemical and energy industry: Seamless steel pipes are used for the transportation of highly corrosive oil and gas media, and they are also used in chemical equipment such as large reactors, high-pressure heat exchangers, and supporting pipelines for distillation towers
• Other fields: Seamless steel pipes are also used in fertilizer equipment, hydraulic and pneumatic cylinders, diamond core drilling and other fields to meet the special needs of different industries
