Hot-rolled thick-walled steel pipe is a thick-walled steel pipe rolled by heating a steel plate.

The word "hot coil" alone is a noun, the abbreviation of hot-rolled coil, and the hot coil used here in conjunction with thick-walled steel pipes is a verb, indicating an action.

To put it simply, "hot-rolled thick-walled steel pipe" is a special thick-walled steel pipe made by rolling steel plates under heating. The hot-rolled steel pipe here means heating and rolling the steel plate. . Its meaning should be determined by cold rolled steel pipe.

Hot-rolled thick-walled steel pipes have the characteristics of not harming the raw materials during the production process, that is, the mechanical properties of thick-walled steel plates. In this way, the steel plates are heated and then rolled, and the steel plates are rolled under great conditions. The steel plate is softened, which neither affects its material nor damages its strength, elasticity, tensile and other properties. More thick-walled steel pipe specifications have been added to meet the wall thickness that cannot be achieved by cold-rolled steel pipes.

Application of hot-rolled thick-walled steel pipes: Hot-rolled thick-walled steel pipes change the shortcomings of fixed specifications and models of seamless steel pipes. Enriching specifications and models is another major feature of hot-rolled thick-walled steel pipes. In production During the process, hot-rolled thick-walled steel pipes are widely used, especially in large equipment such as oil cylinder production, bridge construction, engineering columns, and large rollers. It saves materials, labor, etc. for the above-mentioned enterprises and units, reduces production costs, and improves the market competitiveness of finished products, which plays a certain role in effectively promoting the development of enterprises.
