Description

ASTM A53(also referred to as ASME SA53 pipe) is a carbon steel alloy, which can be used as structural steel or for low-pressure pipelines and is also acceptable for ordinary uses in steam, water, gas and air lines.The alloy specifications are set by ASTM International in the specifications ASTM A53 / A53M.

ASTM A53 Steel Pipe Specifications
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 pipe is our most polar product under this specification and A53 pipe is commonly dual certified to A106 B Seamless pipe.

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.Type F is not intended for flanging.
2.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.
3.Type E is furnished either nonexpanded or cold expanded at the option of the manufacturer.

Scope
ASTM A53 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.

Shengtian Group has a full range of stock in ASTM A53 steel pipe (ASME SA53 steel pipe).
Grade B
NPS ¼” to NPS 26” O.D.
Wall thickness: Schedules 10 through 160, STD, XH and XXH
Commonly requested unscheduled walls up to 4” and certified minimum wall items.

Production process of ASTM A53
Seamless steel pipe manufacturing process
1.Production process of hot-rolled seamless steel pipe: tube billet → heating → perforation → three-roller/cross-rolling & continuous rolling → de-pipe → sizing → cooling → straightening → hydraulic test → marking → seamless steel pipe with leverage effect Detected.
2. Production process of cold drawn seamless steel tubes: tube blank → heating → perforation → heading → annealing → pickling → oiling → multiple cold drawing → blank tube → heat treatment → straightening → hydraulic test → marking → storage.
Tips:Seamless pipe is often made by drawing a solid shape over a mandrel to form the configuration of a tube. Welded pipe is more commonly made by rolling a flat strip of material into a tube and joining the edges together with a longitudinal weld. The weld can be made by either Electric Resistance Welding (Type E) or by Furnace Butt Welded/Continuous Welding (Type F).

Applications of ASTM A53
1.Construction: the pipeline underneath, the groundwater, and the hot water transportation.
2.Mechanical processing, bearing sleeves, processing machinery parts, etc.
3. Electrical: Gas delivery, Hydroelectric power fluid pipeline

4.Anti-static tubes for wind power plants, etc.
