​​ UNS S31603 / EN 1.4404 / ASTM A269 TP316L Seamless Coiled Tubing​

​​Shanghai Toko Tech Co., Ltd.​ is a professional supplier of high-performance special alloy pipes and components. Among its core products, ​316L seamless coiled tubing​ stands out for its exceptional corrosion resistance and reliable performance in demanding applications.​​

​​Typical Specifications (Customizable):​​

· ​​Material Grade:​​ UNS S31603 / EN 1.4404 / ASTM A269 TP316L

· ​​Outer Diameter (O.D.):​​ φ3.18 mm ~ φ25.4 mm(1/8 inch ~ 1 inch) 

· ​​Wall Thickness (W.T.):​​ 0.5 mm ~ 2.0 mm (0.02inch~0.083inch)

· ​​Coil Length:​​ 90-1000 meters per continuous coil (exact length depends on O.D. and W.T.)

· ​​Standard:​​ ASTM A213, A269, A312. ASME SA213, SA269, SA312. AMS 5507,5647. MIL-T 6736. BS 970 Pt. 4, BS EN 10216-5. DIN 17458

Key Features & Advantages:​​

· ​​Superior Corrosion Resistance:​​ The high ​​Molybdenum​​ (Mo) content (typically 2-3%) significantly enhances resistance to pitting and crevice corrosion in chloride-ion environments, outperforming standard 304/316 grades.

· ​​Excellent Manufacturing Properties:​​ Exhibits good formability and weldability, facilitating easy installation and fabrication into complex systems.

· ​​Low Carbon Content (L-Grade):​​ The carbon content is controlled to a maximum of 0.03%, minimizing the risk of ​​sensitization​​ (chromium carbide precipitation) during welding, thereby maintaining its corrosion resistance in welded structures.

· ​​Seamless & Continuous Length:​​ The seamless structure ensures uniformity and higher pressure integrity, while the long coiled length eliminates potential leak points at welds and simplifies routing around obstacles.

· ​​High-Quality Surface Finish:​​ Produced through advanced cold drawing and bright annealing processes, resulting in a smooth surface that minimizes friction resistance and reduces the potential for fouling or contamination.

Primary Applications:​​

This tubing is ideal for critical services across various industries, including:

· ​​Chemical & Petrochemical Processing:​​ Transfer lines for corrosive media, instrument lines, sample lines.

· ​​Oil & Gas:​​ Chemical injection lines (e.g., methanol, inhibitors), hydraulic control lines, instrument tubing on offshore platforms.

· ​​Pharmaceutical & Food Processing:​​ High-purity fluid transfer lines where cleanliness and corrosion resistance are paramount.

· ​​Marine & Shipbuilding:​​ Systems exposed to saltwater environments.

· ​​General Industrial:​​ Heat exchangers, pressure gauges, and other equipment requiring reliable corrosion-resistant tubing.

​​Why Choose TOKO TECH's 316L Coiled Tubing?​​

TOKO TECH ensures product quality through strict control from material selection to final packaging, often including ​​100% eddy current testing (ET)​​ and ​​hydrostatic/pneumatic testing​​. The coils are typically protected by ​​VCI (Vapor Corrosion Inhibitor) packaging​​ or ​​vacuum sealing​​ to prevent corrosion during transit and storage.

In summary, TOKO TECH's 316L seamless coiled tubing offers a robust combination of ​​excellent corrosion resistance, design flexibility from coiled form, and reliable performance​​, making it a trusted choice for engineers designing systems for harsh operating conditions.
