The ASTM A53 standard was developed by ASTM International and covers carbon steel pipes for a variety of purposes, including seamless and welded pipes. ASTM A53 black pipe (also known as ASME SA53 pipe) is widely used in mechanical and pressure applications, as well as general purposes for steam, water, gas and air piping. The standard applies to welding and covers forming operations such as coiling, bending and flanging, although there are limitations under certain conditions.
ASTM A53 Specifications and Types
ASTM A53 carbon steel pipes can be divided into three types and two grades:
Type F: Longitudinal furnace butt welded or with a continuous weld (Grade A only).
Type E: Longitudinal resistance welded (Grades A and B).
Type S: Seamless pipe, produced by hot working and possible cold finishing (Grades A and B).
Of the three types, A53 Grade B
seamless pipe is the most prominent product under this specification, usually dual certified to meet the standards of A106 B seamless pipe. These pipes are suitable for nominal pipe diameters (NPS) ranging from 1/8 inch to 26 inches.
What is ASTM A53 black steel pipe?
ASTM A53 black steel pipe refers to semi-smooth surface pipes treated with black coating, commonly used in mechanical and pressure applications. It is suitable for various fluid transportation, such as steam, water, air and gas. The pipes covered by this standard have nominal (average) wall thickness and are suitable for welding and various forming operations. Its size is specified by two dimensionless numbers: nominal pipe size (NPS) or inside diameter (ID) and pipe specification (SCH, indicating wall thickness).
Process and Standards of ASTM A53
The production processes of ASTM A53 black steel pipe mainly include:
HFI (high frequency induction welded pipe)
EFW (electric fusion welded pipe)
These pipes meet multiple international standards, including
API 5L, API 5CT, EN10217, DIN 2458, IS 3589, JIS G3452 and BS1387, etc.
