ASTM A53 Seamless Steel Pipes
ASTM A53 seamless steel pipe is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas and air lines. For Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless.
GR A, GR.B
Outer Dimensions: 21.3mm – 609.6mm
Wall Thickness: 2.0mm – 59.54 mm
Length: max 16000mm
The products are supplied with 3.1 specific test certificates, according to EN 10204. Certification according to 3.2 can be agreed at the time of ordering.
Oil-dip, Varnish, Passivation, Phosphating, Shot Blasting.
Both ends of each crate will indicate the order no., heat no., dimensions, weight and bundles or as requested.
Bare packing/bundle packing/crate packing/wooden protection at the both sides of tubes and suitably protected for sea-worthly delivery or as requested.
A53 pipe comes in three types and two grades,
A53 Type F, which is longitudinally furnace butt welded or continuous welded (Grade A only)
A53 Type E, which is longitudinally electric resistance welded (Grades A and B)
A53 Type S, which is seamless pipe, produced by hot working, and possibly cold finishing, the steel (Grades A and B). ASTM A53, Type S is now currently an outdated specification and has been replaced by ASTM A106 specification for seamless carbon steel pipe.
This is a standard set by the standards organization ASTM International, a voluntary standards development organizations that sets technical standards for materials, products, systems, and services.
This specification covers Seamless and Welded, Black and Hot-Dipped Galvanized nominal (average) wall pipe for coiling, bending, flange and other special purposes and is suitable for welding. Continuous-Welded pipe is not intended for flange. Purpose for which pipe is intended should be stated on order. 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 designator 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.
Permissible Variations in Wall Thickness
The minimum wall thickness at any point shall not be more than 12.5% under the nominal wall thickness specified.
Permissible Variations in Weights per Foot
Weight of any length shall not vary more than 10% over and 3.5% under that specified.
