The development of steel tube production technology began with the rise of the bicycle manufacturing industry, the exploitation of oil in the early 19th century, the manufacturing of ships, boilers, and aircraft during the two world wars, the manufacturing of thermal power boilers after World War II, the development of the chemical industry, as well as the drilling, extraction, and transportation of oil and natural gas. All these factors have significantly driven the growth of the steel tube industry in terms of variety, output, and quality.
Steel tubes are not only used for transporting fluids and powdered solids, exchanging thermal energy, and manufacturing mechanical parts and containers, but they are also an economical steel material. Using steel tubes to manufacture structural grids, pillars, and mechanical supports for buildings can reduce weight, save 20-40% of metal, and enable factory-based mechanized construction.
Seamless steel tubes and stainless steel tubes are two categories with broad application fields. Seamless steel tubes are one of the essential raw materials in economic construction, often referred to as the "blood vessels" of industry.
Seamless tubes are widely used as tubes for the machinery industry (primarily hydraulic and pneumatic cylinder tubes, hydraulic oil pipes, automotive transmission shaft tubes and half-shaft bushings, bearing steel tubes, belt conveyor idler tubes, printing and dyeing roller tubes, etc.), tubes for the petroleum and geological industries (oil pump tubes, drilling tubes, oil tubes, casing pipes, drill pipes, etc.), tubes for the chemical industry (petroleum cracking tubes, high-pressure tubes for fertilizers, tubes for chemical equipment and pipelines), tubes for power station boilers and heat exchangers, among others.
