ASTM A333 SEAMLESS LOW TEMPERATURE CARBON STEEL PIPE (LTCS PIPE)

The ASTM A333 Arade 6 specification covers seamless and welded carbon steel pipes for low-temperature service (down to -150 degrees F°).  A333 pipe vs A106 shall be used in environments with extremely low temperatures, or for compressed gas applications. Specific nominal pipe size/schedule foreseen by the ASME B36.10 specification are not manufactured in A333 materials as higher wall thicknesses have a negative effect on the impact properties of the pipe at very low temperatures.

1/8″NB TO 30″NB IN

Wall Thickness : 2.0mm-60mm

Grade: ASTM A333 Gr. 1,Gr. 3,Gr. 6...

Single Random: 17′ ~ 24′ lengths

Double Random: 36′ ~ 44′ lengths

TESTING REQUIREMENTS

IMPACT TEST

Low-temperature carbon steel pipes are supplied in normalized conditions and the Charpy impact test is always executed at specific temperatures to ensure the compliance of the products to the temperature range set by the standard (carbon steel temperature limit for A333 pipes).

MECHANICAL TESTS

The mechanical testing on low-temperature carbon steel pipes shall be executed as follows:

transverse/longitudinal tension/flattening/hardness/bend: tests to be made on 5% of the pipe from each treated lot. For smaller lots, at least one pipe has to be tested. For material heat treated by the continuous process, tests shall be made on a sufficient number of pipe to constitute 5% of the lot, but in no case less than 2 pipes.

Hydrostatic/ impact/one notched bar impact: shall be made from each heat represented in a heat-treatment load on specimens taken from the finished pipe.

We recommend purchasing the ASTM A333 specification from the ASTM website or the IHS store to get a complete understanding of this topic.
