Description
ASTM A213 Seamless Alloy Steel Pipes are a family of high-performance tubing solutions defined by rigorous standards, engineered to excel in high-temperature, high-pressure industrial applications. As a cornerstone of the ASTM A213 standard—dedicated to seamless alloy and stainless steel tubing for critical thermal service—these pipes encompass a range of grades, each with tailored specifications to meet the demands of boilers, superheaters, heat exchangers, and petrochemical process systems
Across all ASTM A213 grades, mechanical specifications ensure strength, ductility, and durability under extreme conditions:
Tensile Strength: Minimum 415 MPa (60,000 psi) for Cr-Mo grades; up to 515 MPa (74,700 psi) for stainless steel grades.
Yield Strength: Minimum 205 MPa (30,000 psi) for lower-alloy grades; up to 205 MPa (30,000 psi) for high-chromium alloys.
Elongation: Minimum 20-30% in 50 mm (2 inches), ensuring flexibility during installation and resistance to fracture under thermal expansion.
These properties make ASTM A213 pipes suitable for cyclic pressure and temperature fluctuations in critical systems.

ASTM A213 pipes undergo stringent processes to meet quality standards:
Production: Hot-finished (for larger sizes) or cold-drawn (for precision dimensions), with annealing to optimize grain structure and reduce residual stress.
Non-Destructive Testing: Ultrasonic testing (for internal defects), eddy current testing (for surface flaws), and visual inspection to ensure defect-free surfaces.
Hydrostatic Testing: Conducted at 3.45 MPa (500 psi) minimum (or higher per grade) to verify pressure tightness.
Chemical Analysis: Verified via spectrometric testing to confirm alloy composition compliance.
