Seamless steel pipes have hollow sections and are widely used as pipes for transporting fluids. Such as pipelines transporting oil, natural gas, coal gas, water and certain solid materials, etc. Compared with solid steel materials such as round steel, steel pipes are lighter in weight when the bending and torsional strength is the same, and they are an economical cross-section steel material. 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. Steel pipes are used to make ring-shaped parts. It can improve material utilization, simplify manufacturing processes, save materials and processing hours, such as rolling bearing rings, jack sets, etc., which have been widely manufactured with steel pipes. The standing resource materials are,,,,, etc. Thermal expansion seamless pipe] [Thermal expansion seamless steel pipe] * seamless steel pipe, * thermal expansion steel pipe, * seamless steel pipe *,) can be used by the four major domestic steel plants (Tianjin seamless steel, Baotou Steel, Wuxi Zhenda, Shandong) and other seamless steel pipes produced by thermal expansion to specifications * seamless steel pipe. Thermal expansion steel pipes, as an extension of the main line of smelting and rolling pipes, adopt medium-frequency heating, hydraulic push expansion process, hydraulic pressure testing, ultrasonic online flaw detection, eddy current flaw detection, physical and chemical testing and other comprehensive testing methods to ensure perfect and seamless The reliability and stability of seamed steel pipe quality.
