The temperature conditions of the two experiments are basically the same, but the length and force of the weld are different. In the bending test, the weld is located on the side of the main surface of the bend, while in the flattening test, the weld is perpendicular to the direction of load application.

The steel sleeve direct-buried thermal insulation pipe is suitable for high-temperature steam pipelines for central heating in cities and towns, as well as high-temperature thermal pipelines for petroleum, chemical, electric power and other industrial sectors.

The quality of the seamless steel pipe is directly affected by the quality of the tube blank. In order to ensure the quality of the seamless steel tube, the quality of the tube blank must be guaranteed first.

As far as the dredging industry is concerned, with the development of dredging projects to further and deeper waters, the length of steel pipes filled by dredgers in the land area continues to increase, and the impact of transportation links on production is further increased.

With the continuous improvement of people's health, stainless steel products are becoming more and more popular, so how can stainless steel seamless pipe be stainless steel and corrosion resistant?

Ultra-high molecular weight polyethylene wear-resistant pipe is a new type of engineering pipe fittings with excellent comprehensive performance. It can be widely used in conveying various powders, slurries, fluids and gases, and has a broad market potential.
