Types of Welded Stainless Steel Pipes

Select from our comprehensive range of grades, each delivering distinct performance advantages for your specific industrial application.

304/304L Stainless Steel Welded Pipe

Our 304 stainless steel pipe undergoes precision welding, which transforms flat stainless steel sheets into robust tubular structures. The advanced process ensures exceptional joint strength and structural durability. This versatile 304 ss pipe grade excels in maintaining dimensional accuracy while offering superior formability for custom configurations.

The 304L variant, with a lower carbon content than the 304 grade, provides better formability without compromising strength. Both standard 304 and 304L welded stainless steel pipe options are available in custom sizes, lengths, and wall thickness specifications to match your exact requirements.

316/316L Stainless Steel Welded Pipe

Our 316L stainless steel pipe delivers exceptional corrosion resistance and durability against chemical exposure. This grade, with its lower carbon content (if compared to the 316 option), prevents carbide precipitation — a crucial advantage for welding applications where structural integrity is paramount.

The 316 stainless steel welded pipe variant maintains superior strength in demanding environments. It offers consistent performance under continuous operation. Both grades feature impeccable welding, which transforms premium stainless steel sheets into reliable welded solutions with flawless joint integrity.

Welded vs Seamless Pipe: What's the difference?

Our welded steel pipe starts as a premium metal sheet, precision-rolled, and joined with advanced technology. The seamless option is extruded from solid metal stock and creates a continuous surface without welds. Both manufacturing methods yield high-quality solutions with distinct advantages.

We offer both welded options and seamless pipes and provide expert guidance to match your specific project requirements with the optimal pipework type. Each variety maintains strict dimensional accuracy for precision applications.
