Seamless Steel Pipeline (Seamless pie).

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.

    I am involved in a work of laying of pipe line, and the specialist proposes to use ERW pipeline instead of the seamless pipe established by the initial engineering. I have actually been consulting the normative recommendations and do not get the constraint to making use of ERW pipeline in services such as fuel oil (120PSI) in a submarine lying.
    Can anyone advise me something about it or inform me that I find reference document?.
    Thanks ahead of time for your help …

      ERW pipe surface quality is much better than the seamless steel pipeline.

      In terms of corrosion ERW can last longer than seamless pipe approximately 3-4 years longer. The cost is expensive for ERW. It really depends upon the maker if they offer it for long pipeline distance.

      Usually Seamless pipe is more suggested.

      Hopefully it helps.

  2. Distinction betweem astm a53 steel and also astm a106 steel

    • As an example when we contrast between A106-B as well as A53-B smooth from chemical composition viewpoint, we find that: 1. A106-B includes silicon, minutes. 0.10% where A53-B has no%, and also silicon is the vital aspect for improving
      the warmth resistance requirements. 2. A106-B includes manganese 0.29-1.06%, where A53-B 1.2%. 3. A106-B has reduced sulfur and also phosphorus, max. 0.035% where A53-B has 0.05 and also 0.045% specifically.

      Seamed pipe would be, towel with a filler such as string, planted right into a coat to reveal cuffs or a side! Smooth pipe exists such a thing, could be unseen mending or comparable fine technique.
