• Brief Introduction

ASTM A53 106b ERW Steel Pipe

ASTM A53 106b ERW Steel Pipe welding round pipes also are called as Electric Resistance Welded Pipes. This type of steel pipes and tubes are widely used in various fields such as  engineering purposes, fencing, scaffolding, line pipes etc. ASTM A53 106b ERW Steel Pipe  and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes.

While manufacturing ASTM A53 106b ERW Steel Pipe, there are some strictly standard: high-quality, continuous-cast, fully killed, control-rolled, fine-grain, low-carbon steel. High performance ASTM A53 106b ERW Steel Pipe and tubing possess high strength corrosion resistance, high deformability, high strength and high toughness.

ASTM A53 106b ERW Steel Pipe is available with square ends or beveled for welding, threaded and coupled and victaulic grooved.

Surface finish are available in black or bare, or with protective coatings

A53 PIPE Specifications

A/SA53
NPS 1/4″ – 30″
Schedules 10 through 160, STD, XH and XXH
ASTM A53 pipe (also referred to as ASME SA53 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 for forming operations involving coiling, bending, and flanging, subject to certain qualifications.

American Piping Products stocks a full range of A53 pipe (SA53 Pipe) in:

*Grade  B
*NPS ¼"”" to 30” diameter
*Schedules 10 through 160, STD, XH and XXH

Scope

ASTM A53 106b ERW Steel Pipe covers Seamless and Welded, Black and Hot-Dipped Galvanized nominal (average) wall pipe for coiling, bending, flanging and other special purposes and is suitable for welding. Continuous-Welded pipe is not intended for flanging. Purpose for which pipe is intended should be stated on order.

Permissible Variations in Wall ThicknessHot-Dipped Galvanizing

Sets standards for coating of ASTM A53 106b ERW Steel Pipe with zinc inside and  outside by the hot-dipped process. Weight of coating must not average less than 1.8 oz. per square foot and not less than 1.6 oz. per square foot.
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

Plus or minus 10%

Permissible Variations in Outside Diameter

Outside Diameter at any point shall not vary from standard specified more than:

Number of Tests Required

Seamless and ASTM A53 106b ERW Steel Pipe — Bending, flattening, tensile on one length of pipe from each lot of 500 lengths or less of a size. Continuous-Weld — Bending, flattening, tensile

Hydrostatic Testing

Hydrostatic inspection test pressures for ASTM A53 106b ERW Steel Pipe plain end and threaded and coupled pipe are specified.
Hydrostatic pressure shall be maintained for not less than 5 seconds for all sizes of seamless and electric-resistance-weld pipe.

Mechanical Tests Specified

Tensile Test — Transverse required on ERW for NPS 8 and large. Sending Test (Cold) — STD and XS-NPS 2 and under XXS-NPS 1 1/4 and under.

Flattening Test — NPS 2 and larger STD and XS. (Not required for XXS pipe.)
