ASTM A269 TP316L Stainless Steel Bright Annealed Coil Tube For Industrial Fluid Application

ASTM A269 TP316L Stainless Steel Bright Annealed Coil Tube For Industrial Fluid Application

ASTM A269 TP316L Bright Annealed Coiled Tube is a premium-grade, small-diameter stainless steel tube. This stainless steel tube is engineered for reliability in industrial fluid transfer applications. The 316L material grade provides superior corrosion resistance, especially to chlorides and acids, compared to 304-grade stainless steel. The Bright Annealing (BA) process not only optimizes the metallurgical structure for maximum corrosion resistance but also delivers an exceptionally smooth, passive surface that minimizes fluid adhesion, bacterial growth, and pressure drop. Supplied in coils, it drastically reduces installation time and potential leak points in systems requiring long, bending runs. YUHONG GROUP is the manufacturer and supplier of ASTM A269 TP316/316L/316Ti, 304/304L, TP317L, TP347/347H, TP321, TP310, TP310S stainless steel bright annealed tubes for more than 35 years. Our tubes can be processed into coiled tubes or straight tubes according to the client’s requests.The regular outer diameter size of coiled tubes ranges from 3.18mm to 25.4mm, while the common wall thickness ranges from 0.71mm to 3.4mm.

Mechanical Properties of ASTM A269 TP316L Stainless Steel Tube:

Key Features of Stainless Steel Coiled Tubes:

• Continuous Length: Eliminates fittings/joints over long runs, reducing installation cost and leak potential.
• Flexibility: Can be bent and routed around obstacles easily.
• Corrosion Resistance: 316L offers excellent resistance to a wide range of chemicals, process fluids, and chlorides.
• Cleanability & Hygiene: BA surface is non-porous, easy to clean/sterilize, and ideal for sanitary processes.
• Pressure & Vacuum Tightness: Seamless-like integrity from precision welding and annealing.
• Durability & Strength: High mechanical strength and good toughness across a wide temperature range.

Different Applications of ASTM A269 TP316L Bright Annealed Coiled Tubes:

These tubes are used across industries where reliability, corrosion resistance, and efficient installation are critical:
