ASTM A213 316/316L Polished Seamless Tube 1/4"-2" OD 6m Length for Heat Exchanger Applications

SMLSCO seamless tubes undergo precision multi-pass inner and outer wall polishing to ensure high surface smoothness without scratches, effectively reducing fluid resistance and preventing scaling for optimal heat exchange efficiency. The bright annealing process performs heat treatment under controlled atmosphere, eliminating cold working stress and restoring material mechanical properties while forming a bright oxide-free surface for maximum cleanliness and corrosion resistance.

316/316L stainless steel offers excellent corrosion resistance due to molybdenum content, particularly in chloride environments, effectively resisting pitting and crevice corrosion. With superior high-temperature strength and creep resistance, it's ideal for high-temperature, high-pressure conditions. The low-carbon 316L version maintains excellent intergranular corrosion resistance without post-weld annealing, ensuring long-term stability in harsh industrial environments.

SMLSCO precision seamless tubes are core components designed specifically for various heat exchanger and condenser systems including shell and tube, coil configurations. Widely used in petrochemicals, energy and power, food processing, and HVAC industries, providing stable heat exchange performance, excellent high-pressure resistance, and reliability under thermal cycling conditions.

SMLSCO implements a rigorous three-level quality inspection system with 100% comprehensive testing of finished products. All testing data and product photos are archived for complete traceability. We support third-party inspections by organizations such as SGS and TÜV, providing transparent and reliable quality assurance.
