ASTM A53 Carbon Fluid Seamless Steel Pipe

A53 Fluid Lines are hollow section steel pipes that are seamless throughout. The Steel Pipe has a hollow section and is used as a pipeline to transport a large amount of oil, natural gas, natural gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe is lighter in weight with the same bending and torsional strength. A53 is an economical section steel, which is widely used in the manufacture of structural parts and mechanical parts such as oil drill pipes, automobile transmission shafts, bicycles, etc. Scaffolding and steel scaffolding for construction. We also have other similar steel pipe, such as Structural Steel Pipe, Boiler Steel Pipe, polished steel pipe, Alloy Steel Pipe, Auto Parts Steel Pipe, etc.
Require;
When the Welded Pipe is used as a fluid conveying pipe, it has different requirements from ordinary steel pipes:
1. Welds are not allowed to leak. For the welded pipes required by API, the weld seam of each welded pipe also needs to be subjected to ultrasonic flaw detection and hydrostatic test;
2. When transporting corrosive chemical solutions, the inner walls of all steel pipes must be treated with anti-corrosion;
3. All fluid pipes require internal deburring to reduce fluid transfer resistance.
length;
1. Hot rolled (extruded, expanded) steel pipe 3-12m
2. Cold drawn (rolled) steel pipe 3-10.5m
curvature;
1. When the wall thickness is less than or equal to 15mm, it shall not be greater than 1.5mm/m
2. When the wall thickness is >15mm, it shall not be greater than 2.0mm/m
3. When the outer diameter is greater than or equal to 351mm, it shall not be greater than 3.0mm/m

Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless

ASTM A53 (ASME SA53) Carbon Steel Pipe is a specification that covers seamless and welded black and hot-dipped Galvanized Steel Pipe in NPS 1/8″ to NPS 26.  A 53 is intended for pressure and mechanical applications and is also acceptable for ordinary uses in steam, water, gas, and air lines.

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

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

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 Grade B Seamless is our most polar product under this specification and A53 pipe is commonly dual certified to A106 B Seamless pipe.

Standard

Permissible variations in outside diameter

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

Tensile requirements

Number of tests required

Seamless and Electric-Resistance-Welded — 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 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.)

Standard Weight

Single Random — 16′ – 22′. 5% may be jointers. If Plain Ends — 5% may be 12′ – 16′.

Double Random — Shortest Length 22′, minimum average for order 35′.

Extra Strong and Double Extra Strong

Single Random — 12′ -22′. 5% may be 6′ – 12′.

Double Random (XS and lighter) — Shortest Length 22′, minimum average for order 35′.

Lengths longer than single random with wall thicknesses heavier than XS subject to negotiation.

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.
