I have years of experience dealing with many pipes to give the precise size of A53 grade B pipe. ASTM, or the American Society for Testing Material, specifies standards for A53 pipes and tubes for its many grades. You need to know the right size of ASTM A 53 grade B pipe for specific use to succeed.

ASTM specifies standards for carbon steel pipes in all forms, like welded, seamless, and zinc-coated galvanized pipes. The specifications of the A53 steel pipe define the size for OD or outer diameter to be between 10.3 mm or one-eighth of an inch to 660 m or 26 inches.

The outer diameter varies depending on the many A53 pipes for different sizes and schedules. For example, the outer diameter of ½" x SCH 40 is 21.3 for lengths 5 to 7. For ¾" x SCH 80, the outer diameter is 26.7 mm.

Choosing the right size of the ASTM A53 galvanized pipe is essential for its many applications. It includes water treatment, oil & gas pipeline systems, mineral slurry, construction & structure, etc.

To know which is better between the two ASTM A 53 pipes grades, check the following facts.

ASTM A53 carbon steel pipes grade A have a carbon content of 0.025% and 0.95% manganese, which is lesser than A53 pipe grade B has a carbon content of 0.030% and manganese of 1.2%

The remaining elements, like phosphorous, sulphur, copper and others, are of the same quantities in the two grades.

ASTM A53 GR B erw pipe and A53 galvanized steel pipe available in different wall thickness of 3mm-12mm

The SA 53 GR B seamless pipe's wall thicknesses are between 1.65mm to 20mm. Since the hot rolling process produces, these pipes are best for transporting fluids at high temperatures and pressure.

The wall thickness of A 53 welded pipes ranges between 3 mm to 12 mm. The wall thickness of A 53 seamless pipes depends on the schedule, grade and others.

ASTM A 53 Gr B ERW pipe is the most common steel pipe, making it essential to know its working pressure. Only by knowing the working pressure will it help to use if for specific applications to be successful with no damages.

For applications up to 400 F, Barlow's formula calculates the allowable or working pressure with a yield strength of 35000 psi and a design factor of 0.7. It is (35000 psi) x .07 = 24500 psi

It is essential to have a Mill test certificate to determine whether pipes have European standard 10216; hence, an A 53 schedule 40 pipe Black Mill test certificate is essential. It confirms many standards specified by the ASTM for 53-grade pipes.

It is essential to get the Mill test certificate from the manufacturers or suppliers to confirm its high standards and quality to buy pipes, especially carbon steel pipes like ASTM A 53

ASTM A53 carbon steel pipe availble in A53 GR B Type F, Type E, and Type S Grade

ASTM A53 Carbon Steel Pipe are available in three types, E, F and S, in two grades, A and B includes
