ASTM A53

Date:2018-02-28    keywords:ASTM A53
ASTM A53 is for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless

ASTM A53 specification covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1/8 to NPS 26. The steel categorized in this standard must be open-hearth, basic-oxygen or electric-furnace processed and must have the following chemical requirements: carbon, manganese, phosphorus, sulfur, copper, nickel, chromium, molybdenum, and vanadium. The tubing shall undergo a seamless or welding process. Tension, bend, and flattening tests shall be performed to make sure that it must adhere to the mechanical properties of the standard. The hydrostatic test shall be applied, without leakage through the weld seam or the pipe body. Nondestructive electric test shall be made to make sure that the full volume of the pipe must be in accordance with the standard. The purchaser shall have the right to perform any of the inspections and tests set forth in this specification where deemed necessary to ensure that the pipe conforms to the specified requirements.

ASTM A53 Steel Pipe Specifications:
A53 pipe comes in three types (F, E, S) and two grades (A, B).

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

Type S—Seamless pipe, Grades A and B.


Permanent Steel Manufacturing Co.,Ltd has a full range of stock in ASTM A53 steel pipe (ASME SA53 steel pipe).

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

ASTM A53 Grade B is the material under the American steel pipe standard, API 5L Gr.B is also the American standard material, A53 GR.B ERW refers to the electric resistance welded steel pipe of A53 GR.B; API 5L GR.B Welded refers to the material Welded steel pipe of API 5L GR.B.

Production process 
Seamless steel pipe manufacturing process is divided into hot-rolled and cold seamless pipe.
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.

Applications
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.
