Introduction
ASTM A213 TP316H Seamless Tube is specifically designed for high-temperature heat exchanger and boiler applications. DLSS supplies tubes in the size 19.05 mm outer diameter × 2.0 mm wall thickness × 6000 mm length, fully manufactured according to ASTM A213 / ASME SA213 standards.
Each tube undergoes a strict testing regime, including 100% Hydrostatic Testing (HT), 100% Eddy Current Testing (ET), and 100% Ultrasonic Testing (UT), ensuring reliable performance in critical applications. With its excellent corrosion resistance and high-temperature strength, TP316H stainless steel is a trusted solution for power plants, petrochemical facilities, and industrial heat recovery systems.
What is ASTM A213 TP316H?
TP316H is a high-carbon modification of the standard 316 stainless steel. The increased carbon content improves its creep resistance and high-temperature strength, making it suitable for continuous operation at elevated temperatures.
Key properties of ASTM A213 TP316H Seamless Tube include:
-
Enhanced mechanical strength at high temperatures
-
Excellent oxidation and corrosion resistance in aggressive environments
-
Long service life in heat exchangers, superheaters, and boilers
-
Seamless construction for superior pressure containment
