ASME SA53, modeled after ASTM A53, is a specification for hot-dipped, galvanized electric resistance welded, Grade B pipe, intended for use in mechanical and pressure applications. SA53 comes in three types (F,E,S) and two grades (A, B). Grade B tends to be the most popular grade for the clients because of the different applications that is convenient for. The outside diameter of grade B ranges from NPS ¼” to NPS 26”. The wall thickness of grade B schedules 10 through 160. The client requests grade B for the outside diameter and the wall thickness based on what application he or she tends to use that piping for. ASME SA53 pipe are designed for welding, grooving, threading, and bending but not for flanging. Common uses for ASME SA53 include structural applications such as piles, beams, pillars, and fencing. It is also used for low pressure uses such as piping for water, air, or steam
Size (mm):
O.D.: 6.0mm - 180 mm
W.T.:1mm - 30 mm
Length: max 11800mm
Steel grade:
ASTM A53 Grade.A
ASTM A53 Grade.B
Usage
For mechanical and pressure use, and also for transporting steam, water, gas and etc.
Mill test certificates will be issued according to EN10204/3.1B .
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 suitable for forming operations involving coiling, bending, and flanging, subject to certain qualifications.
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.
Applications: heat exchangers, condensers, heat transfer equipment and similar pipes.

A53 pipe comes in three types (F, E, S) and two grades (A, B).
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 Type F is manufactured with a furnace butt weld or may have a continuous weld (Grade A only)
