The Seamless Tube 316 Grade is a premium stainless steel tubing solution engineered for applications demanding the highest levels of corrosion resistance, dimensional accuracy, and structural integrity. Unlike welded alternatives, seamless tubes are manufactured without a longitudinal weld seam, resulting in a uniform grain structure throughout the tube wall. This makes them the preferred choice for high-pressure systems, fluid and gas conveyance, instrumentation, hydraulic lines, and critical industrial applications where weld-free construction is essential.
Available exclusively in 316 stainless steel and supplied in 6-metre lengths sold in full lengths only, this product range is offered in two surface finish options: Mill Finish and Bright Finish. The mill finish provides a clean, consistent industrial surface suitable for functional applications, while the bright finish delivers an enhanced aesthetic ideal for visible or semi-decorative installations requiring a smoother appearance.
The dimensional range is extensive, beginning at 4.76 × 0.71mm and extending through to 50.8 × 3.2mm, with a comprehensive selection of outer diameters and wall thicknesses in between. Mill Finish options span the full range, including sizes such as 6.35 × 0.9mm, 7.95 × 1.2mm, 9.53 × 1.65mm, 12.7 × 0.9mm, 12.7 × 2.1mm, 15.88 × 1.6mm, 19.05 × 1.6mm, 25.4 × 1.6mm, and 31.75 × 1.6mm. The Bright Finish selection focuses on key sizes including 6.35 × 1.2mm, 9.53 × 0.9mm, 12.7 × 0.9mm, and 12.7 × 1.2mm.
The use of 316 stainless steel with its molybdenum addition ensures superior resistance to chloride attack, pitting, and crevice corrosion compared to standard 304 grade. This makes the seamless tube especially well-suited for marine environments, chemical processing, food and pharmaceutical manufacturing, and offshore applications where long-term performance under demanding conditions is non-negotiable. With its seamless construction and versatile size range, this product delivers reliability and precision across a broad spectrum of engineering applications.
