Hebei metal Ltd. is a construction materials company, which includes new product development, manufacture, sale and engineering service.Our core product are seamless steel pipes, welded steel pipes,buttweld pipe fitting and steel pipe flanges.

In the industrial sector, welded pipes are widely used due to their high production efficiency, wide range of specifications, and significant cost advantages. Different welding processes result in significant differences in pipe performance, applicable scenarios, and inspection requirements.As energy efficiency and life cost become increasingly important in engineering projects, composite materials, internal and external corrosion protection layers, and more stringent quality traceability systems will become key to competitive procurement. Metal has extensive project experience and can provide professional pipe selection advice and inspection support based on your project conditions. Contact us for customized solutions.

The industrial production of seamless steel pipes mainly follows two routes: one is the piercing-rolling method(Bias rolling / Mannesmann type), and the other is the extrusion method (hot/cold extrusion). Each has its own process flow, advantages, and applicable scenarios. Understanding the differences helps in selecting the appropriate pipe material for different applications.Metal has built a closed-loop quality system from factory to site by integrating raw material inspection, production process control, non-destructive testing, disinfectant and preservative treatment, and on-site processing. For samples of seamless steel pipe or technical support for inspection items, please contact us for customized solutions and quotations.

Welded steel pipes are widely used in structural components, pipelines, scaffolding, curtain walls, and machinery manufacturing due to their high production efficiency and complete range of specifications. However, during procurement and on-site construction, customers often encounter pain points such as dimensional deviations, weld defects and surface corrosion, requiring strict control over material selection, inspection, and after-sales technical support.For sample inspection or project technical support, please contact us for customized solutions and quotations.
