Low Temperature Carbon Pipe (ASTM A333 Gr. 1-6)

Low Temperature Carbon Pipe (ASTM A333 Gr. 1-6)

The ASTM A333 specification covers seamless and welded carbon steel pipes for low-temperature service (down to -150 degrees F). Specific nominal pipe size/schedule foreseen by the ASME B36.10 specification are not manufactured in A333 as higher wall thicknesses have a negative effect on the impact properties of the pipe at very low temperatures. 

 

CHEMICAL COMPOSITION ASTM A333 – ASME SA333 PIPE

Low-temperature carbon steel pipes ASTM A333 are available in multiple grades designated as 1, 3, 4, 6, 7, 8, 9, 10, & 11:

ASTM A333 PIPE GRADE C Si Mn P S Cr Ni Cu Mo V Al
Gr. 1 <=0.30 0.40-1.06 <=0.025 <=0.025
Gr. 3 <=0.19 0.18-0.37 0.31-0.64 <=0.025 <=0.025 3.18-3.82
Gr. 4 <=0.12 0.18-0.37 0.50-1.05 <=0.025 <=0.025 0.44-1.01 0.47-0.98 0.40-0.75 0.04-0.30
Gr. 6 <=0.30 ≥0.10 0.29-1.06 <=0.025 <=0.025
Gr. 7 <=0.19 0.13-0.32 <=0.90 <=0.025 <=0.025 2.03-2.57
Gr. 8 <=0.13 0.13-0.32 <=0.90 <=0.025 <=0.025 8.40-9.60
Gr. 9 <=0.20 0.40-1.06 <=0.025 <=0.025 1.60-2.24 0.75-1.25
Gr. 10 <=0.20 0.10-0.35 1.15-1.50 <=0.03 <=0.015 <=0.15 <=0.25 <=0.015 <=0.50 <=0.12 <=0.06
Gr. 11 <=0.10 <=0.35 <=0.6 <=0.025 <=0.025 <=0.50 35.0-37.0 <=0.50

 

MECHANICAL PROPERTIES ASTM A333 PIPE

The table shows the mechanical properties of the three most common ASTM A333 grades, i.e. ASTM A333 Gr.1, ASTM A333 Gr.3 and, ASTM A333 Grade 6:

Gr. 1 Gr. 3 Gr. 6
Tensile Strength 55,000 65,000 60,000
(min PSI)
Yield Strength 30,000 35,000 35,000
(min PSI)

 

TESTING REQUIREMENTS ASTM A333 PIPE

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. The minimum impact test temperatures by grade are shown in the table below:

A333 Material Grade F C
ASTM A333 Grade Grade 1 -50° -45°
ASTM A333 Grade Grade 3 -150° -100°
ASTM A333 Grade 6 -50° -45°

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.
