ASTM A333 Gr.6 NACE MR0175 Seamless Pipe

For critical services combining low temperature and sour corrosive environments, material integrity is non-negotiable.
The ASTM A333 Gr.6 NACE MR0175 Seamless Pipe is specifically engineered for oil & gas, petrochemical, and offshore applications where both low-temperature toughness and sulfide stress corrosion cracking (SSCC) resistance are required.

Pipe specification: ASTM A333 – Seamless carbon steel pipe for low-temperature service

Grade: Grade 6 (commonly used down to -45°C)

Excellent Low-Temperature Toughness
Stable Charpy impact energy at -45°C, significantly reducing risk of brittle fracture.

H₂S Corrosion Resistance
Fully compliant with NACE MR0175 requirements for hardness, chemistry and heat treatment – resistant to SSCC and HIC.

Clean Steel & Heat Treatment
Normalized or normalized + tempered condition ensures fine grain structure and uniform mechanical properties.

High Dimensional Accuracy
Seamless manufacturing process with strict OD, wall thickness, and concentricity tolerances – easy to weld and install.

OD: 1/2″ – 30″ (custom sizes available)

Wall thickness: 0.055'' - 2'' (1.65 - 50mm)

Length: random or fixed length

Optional services: bevel end, NDT (UT/MT), coating, etc.

Mill with NACE MR0175 certified process control

Supplied with EN 10204 Type 3.1 or 3.2 inspection certificate

Proven experience in energy projects worldwide

Optional HIC / SSCC performance verification

ASTM A333 Gr.6 + NACE MR0175 = Low-Temperature Toughness + Sour Service Compliance + Seamless Integrity
Your trusted solution for challenging low-temperature and sour service environments.
