ASTM A269 TP316L Stainless Steel Seamless Dry Coil Tube

In industries where precision, cleanliness, and reliability are paramount, ASTM A269 TP316L stainless steel seamless coiled tubing has become the material of choice. This product offers excellent corrosion resistance, a smooth internal surface, and high mechanical strength, making it widely used in heat exchangers, condensers, oil and gas, chemical processing, and instrumentation systems. GNEE provides high-quality coils that comply with global standards, ensuring customers receive durable and cost-effective solutions.

ASTM A269 TP316L stainless steel seamless coiled tubing features an outer diameter range of 6.4mm (1/4") to 114.3mm (4.5"), wall thicknesses from 0.51mm (0.020") to 6.0mm, and carbon content controlled at ≤0.03% to enhance intergranular corrosion resistance. With coil weights up to 3000kg, the tubing achieves a bright annealed surface finish quality of Ra ≤ 0.5μm, ensuring strict dimensional tolerances of ±0.05mm for outer diameter and ±5% for wall thickness. Compliant with ASTM A269/ASME SA269 standards, it delivers reliable performance in high-purity fluid transfer, heat exchange, and instrumentation applications.

Applications of 316L Seamless Dry Coil Tube

Heat Exchangers & Condensers – Efficient heat transfer in petrochemical plants.

Instrumentation & Control Lines – Precision tubes for oil & gas and offshore platforms.

Hydraulic & Pneumatic Systems – Continuous coil reduces joint failures in high-pressure lines.
