ASTM A312 TP321 Seamless Pipe Testing and Quality Assurance

TP321 pipes undergo rigorous testing to ensure compliance with ASTM A312 standards:

Non-Destructive Testing (NDT): Includes hydraulic testing, ultrasonic testing, or eddy current testing to detect internal and surface defects.
Mechanical Tests: Tensile, hardness, and flattening tests to verify mechanical properties.
Chemical Analysis: PMI (Positive Material Identification) and spectrometry to confirm composition.
Corrosion Tests: Intergranular corrosion tests (e.g., ASTM A262) to ensure resistance to sensitization.

ASTM A312 TP321 Pipe Comparison with Other Grades

Grade	Key Differences from TP321	Typical Use Cases
TP304	Lower cost, no titanium stabilization; prone to sensitization	Low-temperature corrosive environments
TP316	Molybdenum addition for better pitting resistance	Marine and chloride-rich environments
TP321H	Higher carbon content (0.04–0.10%) for improved high-temperature strength	High-temperature pressure vessels and boilers
