ASTM A213 Pipe | American Standard Steel Products

ASTM A213 specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes. Grades containing the letter H in their designation have requirements different from those of similar grades not containing the letter H. These different requirements provide higher creep-rupture strength than normally achievable in similar grades without these different requirements. The tubes shall be made by the seamless process and shall be either hot finished or cold finished, as specified. Grade TP347HFG shall be cold finished. Heat treatment shall be done separately and in addition to heating for hot forming. The ferritic alloy and ferritic stainless steels shall be reheated. On the other hand, austenitic stainless steel tubes shall be furnished in the heat-treated condition. Alternatively, immediately after hot forming, while the temperature of the tubes is not less than the minimum solution temperature, tubes may be individually quenched in water or rapidly cooled by other means. Tension test, hardness test, flattening test, and flaring test shall be done to each tube. Also, each tube shall be subjected to the nondestructive electric test or hydrostatic test.

1. Surface state
Austenitic steel pipe should be washed to remove the scale, when the use of bright annealing, you do not need pickling.

2. Chemical analysis of finished products
It shall be analyzed from one billet or one pipe per furnace, and the chemical composition determined accordingly shall meet the specified requirements.

3. Mechanical test and grain size
(1) Tensile test:Such as each batch of steel pipe ≤ 50 root, then take a sample for tensile test; each batch of steel pipe> 50, then two steel pipes should take two samples for tensile test.
(2) Flattening test: in each batch of a finished tube at both ends of each sample to take a flattening test, but the root can not used as a flaring sample.
(3) Flaring test: in each batch of a finished tube at both ends of a sample for a flaring test, but the root canal can not be used as a flattening sample.
(4) Hardness test: from each batch of two tubes on the sample to do Brinell or Rockwell hardness test.
(5) Water pressure test: each pipe should be hydrostatic test. When the buyer is specified, a non-destructive test may be used instead.
(6) Grain size: according to ASME E112 standard test.

Size range:
NPS 1/4'' to NPS 24''
Wall Thickness - Schedules 40 through 160, STD, XS, XXS.
Unscheduled heavy wall pipe thicknesses available up to 4 inches.
