China Supplier SS304 SS316 Seamless Stainless Steel Coiled Tube 1/4 1/8 1/16 Bright Anneal Coil Tubing for Heat Exchanger and U Chanel
NAI LOK CO., Ltd established in 2000. has made a name of itself in the list of top suppliers of in China. We focus on the production, research and development, sales of high quality nickel alloy tube and high purity seamless tube. We have more than 20 years of precision tube manufacturing and 10 years of export experience.
Our annual design capacity is 1, 500 tons of seamless steel tubes, utilizing a cold rolling-based process that leads domestically, combined with rolling and drawing processes. We can also provide ODM, OEM and agency services for global customers.
Nickel Alloy Seamless Tube are widely used in petrochemicals, semiconductor manufacturing, instrumentation, military, nuclear power, and other industries, as well as in cutting-edge scientific fields such as national defense and aerospace.
This PVC Coated Stainless Steel Tubing Coil is manufactured from high-quality ASTM A269-compliant TP304 or 316L stainless steel, available in both seamless and welded options. The tubing features an outer PVC protective jacket (PVC Coated), enhancing corrosion resistance, electrical insulation, and mechanical durability while retaining the strength and hygiene of stainless steel. The inner tube surface is bright annealed (BA), ensuring a smooth, clean finish ideal for high-purity applications.
Premium Material
Base Tube Material: TP304 (general-purpose austenitic stainless steel) or 316L (low-carbon with molybdenum for superior corrosion resistance).
Compliance: ASTM A269 standard (for seamless and welded austenitic stainless steel tubing), guaranteeing mechanical and chemical properties.
Dual Protection
PVC Coating: Waterproof, chemical-resistant, and UV-stable outer layer for extended service life in harsh environments.
BA Surface: Oxidation-free, low-roughness interior, suitable for sanitary industries like food and pharmaceuticals.
Flexible Manufacturing
Seamless Tubing: High-pressure resistance for critical applications.
Welded Tubing: Cost-effective solution for standard pressure needs.
Coil Form: Compact for easy transport and installation, minimizing joints and leakage risks.
Wide Applications
Chemical/Pharmaceutical: Resists acids/alkalis; PVC insulates against static.
Food & Beverage: BA surface meets hygiene standards (FDA/GB compliant).
Water Treatment/HVAC: Anti-scaling; PVC protects against outdoor weathering.
