Low Temperature Pipe

ASTM A333 (ASME S/A-333) Pipe grades permit low temperature service. This specification covers nominal (average) walled pipe almost exclusively in seamless.

Pipes are used in low temperature service

Steel pipes are produced accord to ASTM A333 standard

Several grades of ferritic steel are included. Some product sizes may not be available under this specification because heavier wall thicknesses have an adverse effect on low-temperature impact properties.

ASTM A333 Grade 6 and ASME SA 333 Grade 6 are heat treated to achieve normalized condition @ 920 degrees Celsius with controlled microstructure.

Specific Impact requirements

The raw material used for low temperature service pipe is ALUMINIUM killed with high proportion of manganese (more than 1%) combined with low proportions of carbon (less than 0.23%).For low temperature pipe to be certified as LTCS additional impact test should be conducted at low temperatures, as per mandatory requirements in section 8 of ASTM A 333.
