Overview

ASTM A587-22 is the standard specification developed by ASTM International for electric-resistance-welded (ERW) low-carbon steel pipe specifically designed for process lines in the chemical industry. This specification ensures that pipes are manufactured using high-quality aluminum-killed steel, providing reliable performance under the demanding conditions commonly found in chemical processing applications. The scope includes pipes produced via open-hearth, basic-oxygen, or electric-furnace processes, available in both inch-pound and metric units, and covers a wide size range from NPS 1/2 [DN 15] to NPS 10 [DN 250], including additional sizes.

Key Topics

• Material and Manufacturing Process:

  • Pipes are made from aluminum-killed low-carbon steel.
  • Production methods include open-hearth, basic-oxygen, or electric-furnace steelmaking.
  • Pipe is manufactured by electric resistance welding (ERW).

• Heat Treatment and Finishing:

  • Pipes delivered as-welded are normalized above the upper critical temperature.
  • Cold-drawn pipes are normalized after the final draw.
  • Strict requirements for finish, straightness, and marking.

• Dimensional Range:

  • Sizes range from NPS 1/2 [DN 15] up to NPS 10 [DN 250], plus additional sizes.
  • Wall thickness and permissible dimensional variations are clearly specified.

• Testing Requirements:

  • Products must pass several mechanical tests: tensile, flattening, reverse flattening, and flange tests.
  • Pipes are subject to nondestructive testing (NDT), which may include eddy current, ultrasonic, or flux leakage examinations.

• Compliance and Safety:

  • The standard addresses both inch-pound and SI units; each must be used independently.
  • Emphasizes the user’s responsibility for aligning with relevant safety, health, and environmental standards.

Applications

ASTM A587-22 is widely used in the chemical process industry where reliable, corrosion-resistant, and formable pipe is required for transporting process fluids. Key applications include:

• Process Piping: Used for transporting chemicals in plants where durability and reformability (flanging, close-radius bending) are necessary.
• Plant Upgrades and Maintenance: A common choice for repairs and upgrades due to its broad dimensional availability and strict quality assurance.
• Custom Fabrications: Suitable for applications requiring severe forming operations, as the pipe can be subjected to flanging and close-radius bending, especially for sizes up to NPS 4 [DN 100].
• Corrosive Environments: The specification allows for supplementary coatings and galvanizing for enhanced protection, supporting use in challenging environments.

Related Standards

ASTM A587-22 references several supporting and related standards crucial for selection, manufacture, and testing of ERW steel pipe, including:

5.2 Steel may be cast in ingots or may be strand cast. When steels of different grades are sequentially strand cast, identification
of the resultant transition material is required. The producer shall remove the transition material by any established procedure that
positively separates the grades.
5.3 Manufacture—The pipe shall be made by electric resistance welding.
5.4 Heat Treatment—Pipe furnished in the as-welded condition shall be normalized at a temperature above the upper critical
temperature. Cold-drawn pipe shall be normalized after the final cold-draw pass.
6. Chemical Composition
6.1 Heat Analysis—An analysis of each heat of steel shall be made to determine the percentages of the elements specified. The
chemical composition thus determined shall conform to the requirements specified in Table 2 and the chemical analysis shall be
in accordance with Test Methods, Practices, and Terminology A751.
6.2 Product Analysis—When requested on the purchase order, a product analysis shall be made by the supplier from one pipe or
coil of steel per heat. The chemical composition thus determined shall be reported to the purchaser or the purchaser’s representative
and shall conform to the requirements specified in Table 2.
6.3 Retests—If the original test for product analysis fails, retests of two additional lengths of flat-rolled stock or pipe shall be made.
Both retests for the elements in question shall meet the requirements of the specification; otherwise, all remaining material in the
heat shall be rejected or, at the option of the producer, each length of flat-rolled stock or pipe may be individually tested for
acceptance. Lengths of flat-rolled stock or pipe which do not meet the requirements of the specification shall be rejected.
6.4 Supplying an alloy grade of steel that specifically requires the addition of any element other than those listed in Table 2 is not
permitted.
7. Mechanical Requirements
7.1 Tensile Properties:
7.1.1 The material shall conform to the requirements as to tensile properties prescribed in Table 3.
7.1.2 The yield strength shall be determined by the drop of the beam, by the halt in the gauge of the testing machine, by the use
of dividers, or by other approved methods. When a definite yield point is not exhibited, the yield strength corresponding to a
permanent offset of 0.2 % of the gauge length of the specimen, or to a total extension of 0.5 % of the gauge length under load,
shall be determined.
7.1.3 If the percentage of elongation of any test specimen is less than that specified and any part of the fracture is more than ⁄4
in. (19 mm)[19 mm] from the center of the gauge length, as indicated by scribe marks on the specimen before testing, a retest shall
be allowed.
7.2 Flattening Test:
7.2.1 A section of pipe not less than 4 in. (102 mm)[100 mm] in length shall be flattened cold between parallel plates in two steps.
The weld shall be placed 90° from the direction of the applied force. During the first step, which is a test for ductility, no cracks

or breaks, except as provided for in 6.2.57.2.5, shall occur on the inside or outside surfaces until the distance between the plates
is less than the value of H, calculated by the following equation:
H 5 11e t / e1t/D (1)
@~ ! # @ #
where:
H = distance between flattening plates, in.,
H = distance between flattening plates, in. [mm],
t = specified wall thickness of the pipe, in.,
t = specified wall thickness of the pipe, in. [mm],
D = specified outside diameter of the pipe, in., and
D = specified outside diameter of the pipe, in. [mm], and
e = deformation per unit length (0.09 for low-carbon steel).
7.2.2 During the second step, which is a test for soundness, the flattening shall be continued until the specimen breaks or the
opposite walls of the pipe meet. Evidence of laminated or unsound material, or of incomplete weld that is revealed during the entire
flattening test shall be cause for rejection.
7.2.3 Surface imperfections in the test specimens before flattening, but revealed during the first step of the flattening test, shall
be judged in accordance with the finish requirements.
7.2.4 Superficial ruptures resulting from surface imperfections shall not be cause for rejection.
7.2.5 When low D-to- t ratio tubulars are tested, because the strain imposed due to geometry is unreasonably high on the inside
surface at the 6 and 12 o’clock locations, cracks at these locations shall not be cause for rejection if the D-to-t ratio is less than
10.
7.3 Reverse Flattening Test—A section 4 in. (102 mm)[100 mm] in length of pipe in sizes down to and including ⁄16 in. (20.6
mm)[20.6 mm] in outside diameter shall be split longitudinally 90° on each side of the weld and the sample opened and flattened
with the weld at the point of maximum bend. There shall be no evidence of cracks or lack of penetration or overlaps resulting from
flash removal in the weld.
7.4 Flange Test—A section of pipe not less than 4 in. (102 mm)[100 mm] in length shall be capable of having a flange turned over
at a right angle to the body of the pipe without cracking or showing flaws. This flange, as measured from the outside of the pipe,
