ASTM A333 is the standard designation for seamless and welded steel pipe for application in low-temperature accommodations and other applications with the required notch toughness.
Generally, steel cannot withstand low-temperature settings, which is a primary reason for the material’s failure. At lower temperatures, the material is susceptible to losing its dimensional stability, solely because it contracts. The contraction at lower temperatures causes a reduction in the thickness of the ASTM A333 Grade 6 Pipes, while additionally minimizing its inner diameter.
Preheating of the ASTM A333 Grade 6 Pipes is not recommended and no post-weld heat treatment of the components is compulsory. If multi-pass welding is performed in ASTM A333 Grade 6 Pipes, it is consequential to sanction the weld to cool below 300 Degree F (150 Degree C) afore perpetuating.
