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.

Stainless steel threaded pipe fittings are widely used in petrochemical, pharmaceutical, food, marine engineering, and municipal water supply and drainage industries due to their excellent corrosion resistance, processing precision, and ease of on-site installation. Threaded pipe fittings require no welding or heating, allowing for rapid assembly and disassembly, making them a commonly used and reliable mechanical connection method in small- and medium-diameter piping systems.Metal offers a one-stop service from sample testing and material certification to mass production supply, and provides technical selection advice and on-site support based on project conditions to help customers establish safe, reliable, and economical piping connection solutions.

​In building and structural engineering, I-beams steel are key components that bear bending and shear forces. While the different types appear similar, IPE and IPEAA differ slightly in cross-sectional specifications, recommended applications, and structural properties. Choosing the right type can improve project safety and optimize construction costs.IPE and IPEAA each focus on larger cross-sections and stronger load-bearing capabilities, while the other offers lighter specifications and material savings. We can provide sample materials, cross-section mechanical data, and custom cutting services. Please contact us for project-level selection support and technical consultation.

​In pipeline engineering and equipment manufacturing, the choice between welded and seamless pipes is a critical decision affecting safety, lifespan, and cost. Each type of pipe has its own advantages and disadvantages, and differences in manufacturing processes determine their varying performance in strength, pressure resistance, workability, and price.​We also offer sample testing, mechanical testing, and on-site technical support to help customers achieve the optimal balance between safety, reliability, and cost.
