ASTM A53 Pipe Specifications-Type E/F/S

Contents
erw carbon steel pipe

The ASTM A53 standard have three types, ASTM A53 type F/ E/ S, it is one of the most extensively used carbon steel pipe material standards in the oil & gas, structures, constructions, low-pressure plumbing, conveyor rollers, and other process sectors. 

ASTM A53 is one of the standards of the American Society for Testing and Materials. The various types of finishes available for the ASTM A53 steel pipes are black and Hot-dipped, Zinc-coated, Welded, and Seamless.

TYPES OF ASTM A53 PIPES

ASTM A53 seamless and welded steel pipe is a general, all-purpose pipe. Designed for coiling, bending, and flanging, ASTM A53 carbon steel pipe is suitable for welding. 

- ASTM A53 Type F

Furnace-butt welded continuous Welded Pipe

The Type F Grade A pipe is produced from a continuous coil, and the longitudinal junction is welded by forge welding. Sets of rollers are employed in this procedure to apply mechanical pressure to the heated ends of the coil.

Electric Resistance Welded Pipe

Type E Garde A and Garde B pipes are composed of the continuous coil, and the longitudinal junction is welded by heat generated by electric resistance between the pipe’s opposite ends. A set of rollers is also employed in this operation to unite heated ends. After welding, the weld seam of Grade pipes is heat-treated to a minimum of 540°C.

The size range for the pipes is from NPS 1/8” to NPS 26”.Different pipe sizes, click right to find out.

- ASTM A53 Type S

Seamless Pipe

The extrusion process is used to create Type S pipes.The raw steel needed to make pipes is generated using an open-hearth furnace, an electric furnace, or a basic-oxygen process.

MARKING CONTENTS OF ASTM A53 PIPES

The following markings must be put to each length of pipe (or bundle for lesser diameters):

  • A53 type manufacturer’s name (S, E, F)
  • Diameter and timetable (from 10 to 160 and XXS)
  • “ASTM A53” designation
  • Heat number
  • Pipe length

TYPE OF A53 PIPE ENDS

  • Pipes with diameters less than 0.500 inches and STD / XS pipes with plain or beveled ends
  • Pipe schedules greater than 0.500 inches in diameter and XXS: Ends are squared cut and simple.
  • Thread protection is required for pipes larger than 4 inches if they are supplied with threaded ends.

A&Q

ASTM A53 type E/ F/ S How to Select Steel Grade

Type F-Furnace-butt welded, continuous welded Grade A,
Type E-Electric-resistance welded, Grades A and B, and
Type S-Seamless, Grades A and B.

When Types S and E are required for close coiling or cold bending, Grade A is the preferred grade.
This provision is not intended to prohibit the cold bending of Grade B pipe.
Type E is furnished either nonexpanded or cold expanded at the option of the manufacturer.

What is the difference between A53 Type E and Type F?

Type F, Furnace-Butt-Welded Pipe, Continuous-Welded-Pipe produced in continuous lengths from coiled skelp and subsequently cut into individual lengths, having its longitudinal butt joint forge welded by the mechanical pressure developed in rolling the hot-formed skelp through a set of round passwelding rolls.

Type E, Electric-Resistance-Welded Pipe pro-duced in individual lengths or in continuous lengths from coiled skelp and subsequently cut into individual lengths,having a longitudinal butt joint wherein coalescence is pro-duced by the heat obtained from resistance of the pipe to the flow of electric current in a circuit of which the pipe is a part, and by the application of pressure.

And repair welding of Type F pipe and the weld seam of Type E is prohibited.
