From the point of view of manufacturing technology in 2020,
China hollow section tubes have basic technological improvements in steel production, involving in high purity refining, process metallurgy through hot rolling, and welding control, as well as the progress that has been made in hollow section tube manufacturing technology in each area so far.
For a long time, China hollow section tubes play an active role in the global steel pipe market, such as ASTM A500 is the most common steel specification for hollow structural section in the steel pipe market around the world. This specification is for cold formed welded and seamless carbon steel tubing in round, square and rectangular shapes. ASTM A501 is another standard for hot formed steel tubing. In the recent years,
steel pipe manufacturers in China are committed to technological development in hollow section tube manufacturing. The outstanding feature is the fact that development has been pursued systematically in combination with experiments in response to rapid progress in computers in 2020. For example, China hollow section tubes have supported the progress of each industrial field by developing the supplying steel pipes at the highest technological level. For example,
rectangular steel pipe has been widely used in many structural applications involving in residential, commercial and industrial construction fields in the modern. Rectangular steel pipe is fire resistant and does not warp, twist, split, swell or shrink. It resists dry rot and mildew, termites and carpenter ants. For increased fire resistance, the exterior of the product may be sprayed with a fire retardant material.
Today, China hollow section tubes keep up with the times, committed to meeting the requirements for diversified steel pipe performance, including corrosion resistance treatment by galvanizing and aluminizing in the field of
structural steel pipes, as well as in civil engineering and construction. Other new aspects include optimizing the weldability according to the application, adhesion of composite steel pipes to concrete, reduction of workpiece weight and volume by high strength steel pipes, steel pipes conforming to seismic design standards, and steel pipes matching scenic conditions. However, China hollow section tube has strongly intensive labor in manufacturing, and its profits depend largely on labor saving technologies. Furthermore, production depends to a great extent on the world energy situation in addition to business fluctuations. In that regard, it is very important for China steel pipe manufacturers to optimize flexibly the operational formation in production lines. And each mill has managed to implement this in future.
