Product Description

ASTM A53 Steel Pipe

ASTM A53 Steel Pipe is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas, and air lines.

It is suitable for welding, and suitable for forming operations involving coiling, bending, and flanging, subject to certain qualifications.

The weld seam is heat treated after welding without untempered martensite remains. Also, the weld flash can be removed from both inner and outer surfaces.

Materials and Manufacture

The steel for both seamless and Welded Pipe shall be made by one or more of the following processes: open-hearth, electric furnace, or basic-oxygen. The weld seam of electric-resistance welded pipe in Grade B shall be heat treated after welding.

Applications: heat exchangers, condensers, heat transfer equipment and similar pipes.

Note:

DN — Nominal Diameter

NPS —Nominal Pipe Size

Scope

1.1 This specification2 covers seamless and welded black and hot-dipped Galvanized Steel Pipe in NPS 1/8 to NPS 26 [DN 6 to DN 650] (Note 1), inclusive, with nominal wall thickness (Note 2) as given in Table X2.2 and Table X2.3. It shall be permissible to furnish pipe having other dimensions provided that such pipe complies with all other requirements of this specification. Supplementary requirements of an optional nature are provided and shall apply only when specified by the purchaser.

NOTE 1: The dimensionless designators NPS (nominal pipe size) [DN (diameter nominal)] have been substituted in this specification for such traditional terms as “nominal diameter,” “size,” and “nominal size.”

NOTE 2: The term nominal wall thickness has been assigned for the purpose of convenient designation, existing in name only, and is used to distinguish it from the actual wall thickness, which may vary over or under the nominal wall thickness.

1.2 This specification covers the following types and grades:

1.2.1 Type F—Furnace-butt-welded, continuous welded Grades A and B,

1.2.2 Type E—Electric-resistance-welded, Grades A and B, and

1.2.3 Type S—Seamless, Grades A and B.

NOTE 3: See Appendix X1 for definitions of types of pipe.

1.3 Pipe ordered under this specification is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas, and air lines. It is suitable for welding, and suitable for forming operations involving coiling, bending, and flanging, subject to the following qualifications:

1.3.1 Type F is not intended for flanging.

1.3.2 When pipe is required for close coiling or cold bending, Grade A is the preferred grade; however, this is not intended to prohibit the cold bending of Grade B pipe.

1.3.3 Type E is furnished either nonexpanded or cold expanded at the option of the manufacturer.

1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.5 The following precautionary caveat pertains only to the test method portion, Sections 7, 8, 9, 13, 14, and 15 of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory requirements prior to use.

1.6 The text of this specification contains notes or footnotes, or both, that provide explanatory material. Such notes and footnotes, excluding those in tables and figures, do not contain any mandatory requirements.

1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

A53 pipe comes in three types (F, E, S) and two grades (A, B).

A53 Type E has an electric resistance weld (Grades A and B)

A53 Type S is a Seamless Pipe and found in Grades A and B)

A53 Type F is manufactured with a furnace butt weld or may have a continuous weld (Grade A only)

Mechanical properties of ASTM A53

ASTM A53 is suitable for a variety of forming processes, including coiling, bending, and flanging; continuous weld pipe (Type F) is not suitable for flanging. Please note the use/application of the pipe you require on your RFQ and/or when ordering.

Galvanized A53 Pipe

If ordered galvanized, A53 seamless pipe must be coated inside and out via the hot-dip process. Zinc used for galvanized coatings must conform to Specification B6. The weight of this coating must not be less than 1.8 oz./ft2 (0.55 kg/m2). Test specimens for coating weight testing will be cut in approximately 4” lengths.

ASTM A53 Grade B Pipe

ASTM A53 Grade B Pipe is one such Carbon Steel Pipe grade that comes under this standard. The ASTM A53 Grade B ERW Pipe size ranges between ½ inches to 36 inches and the wall thickness ranges between 3mm to 12mm. A53 Gr B material can is used to weld these pipes that are available in the plain end, beveled, and threaded end.

Seamless Steel Pipe

Packing

Bare packing/bundle packing/crate packing/wooden protection at the both sides of tubes and suitably protected for sea-worthly delivery or as requested.

There are probably hundreds of different methods for packing a pipe, and most of them have merit, but there are two principles that are vital for any method to work prevent rusting and Sea transportation security.

Plastic caps plugged at the two sides of pipe ends

Should be avoided by the steel strapping and transport damage

Bundled signs should be uniform and consistent

The same bundle(batch) of steel pipe should be came from the same furnace.

The steel pipe has the same furnace number, the same steel grade, the same specifications.

Our packing can meet any needs of the customers.
