Frequently Asked Questions
Seamless tubes are made by piercing a solid billet, offering superior pressure resistance for critical apps. Welded tubes are formed from rolled sheets and joined by welding, providing a more cost-effective and flexible solution for structural and moderate-pressure uses.
We utilize industry-standard Electric Resistance Welding (ERW) and Submerged Arc Welding (SAW) to ensure strong, reliable joints that maintain structural integrity.
Yes, when properly alloyed or treated with protective coatings such as galvanization or specialized painting, welded tubes exhibit excellent corrosion resistance suitable for marine and chemical industries.
JCOE is a specialized forming process that rolls plates into a pipe shape with a single longitudinal weld, allowing for the production of large-diameter pipes (up to 2500mm) with high precision.
We provide a wide range of dimensions for structural profiles, typically ranging from 20 x 20 mm to 400 x 200 mm, depending on the specific load requirements of the project.
They are widely used in petroleum and natural gas pipelines, shipbuilding, structural engineering, power generation, automotive chassis, and agricultural irrigation systems.
