seamless steel pipe

Production process of the seamless steel pipeline.

We produce innovation advanced hot rolled smooth steel tubes utilizing continuous tube rolling mills. The hot rolling process includes steel billet → heating → punching → three-roller alter rolling → tube knockout → tube size decreasing → cooling → semi-finished pipe → straitening → water pressure test → labeling → warehouse entry.

rolling procedure, the density of continuous casting slab is around 230mm, while after rough rolling and surface rolling, the thickness is 1 ~ 20mm. Due to little flakiness ratio, the steel plate has a low requirement on its dimensional precision. However, crown control is still important.
Hot Rolled Steel Pipe (Smooth Tube).

Bottom.
If there is any requirement on the microstructure and mechanical structure of steel plates, we can achieve this through specifically controlling the temperature level during various rolling processes, like the temperature level throughout preliminary rolling stage, surface rolling phase and curling phase.
Classification.
The hot rolled steel pipeline is categorized into typical steel pipeline, medium and low pressure boiler pipe, high pressure boiler steel tube, alloy tube, stainless steel pipeline, oil splitting pipeline and geology steel tube.
Features.

Our hot rolled steel pipelines provide various comparative advantages and impressive features, as is manifested by the following. In our way of making the hot rolled steel pipe, the cast structure of steel ingot can be broken, the grains of steel are refined, and the problems of the microstructure of steel are removed, resulting in enhanced mechanical buildings and denser microstructures of the steel product. For specifications of our hot rolled steel pipelines, please see the type attached.
We are a leading hot rolled steel pipe manufacturer and provider based in China. In addition to hot rolled steel tubes, we can likewise produce a variety of other pipelines, consisting of anticorrosion pipes, spiral tubes, ERW bonded steel tubes and LSAW tubes.
