Totten Tubes Inc

Black or Hot-Dip Galvanized, Welded & Seamless Steel Pipe

Totten Tubes supplies ASTM A53 seamless steel pipe in a broad range of sizes to fit any project requirements. A53 steel pipe is intended mechanical and pressure applications, but is also acceptable for and widely used in air, water, steam, and gas lines. A53 pipe is suitable for welding.
 
ASTM A53 is suitable for a variety of forming processes, including coiling, bending, and flanging; continuous weld pipe (Type F) is not suitable for flanging. Please note the use/application of the pipe you require on your RFQ and/or when ordering.

The aspects of the ASTM A53 specification most relevant to our purposes is as follows:

A53 Pipe Materials & Manufacture

Steel materials used to create seamless pipe and welded pipe must be produced via open hearth, electric furnace, basic oxygen, or any combination of these processes. All weld seams in electric-resistance welded A53 Grade B pipe must be heat treated after welding to a minimum of 1,000°F (540°C) to eliminate untempered martensite.

Galvanized A53 Pipe

If ordered galvanized, A53 seamless pipe must be coated inside and out via the hot-dip process. Zinc used for galvanized coatings must conform to Specification B6. The weight of this coating must not be less than 1.8 oz./ft2 (0.55 kg/m2). Test specimens for coating weight testing will be cut in approximately 4” lengths.
  • Permissible Variation in Wall Thickness: The minimum wall thickness at any point in a length of A53 steel pipe must not be more than 12.5% less than the specified wall thickness.
  • Permissible Variations in Outside Diameter: For ASTM A53 steel pipe NPS 1-1/2 and smaller, outside diameter must not exceed 1/64” over and 1/32” under specified diameter. For A53 pipe NPS2 and larger, outside diameter must not exceed 1% over and 1% under specified diameter.

Tensile Requirements of ASTM A53

  Type F Types E and S
Open-Hearth, Basic Oxygen, or Electric Furnace, Grade A Grade A Grade B
Tensile strength, min, psi (MPa) 48 000 (330) 48 000 (330) 60 000 (415)
Yield strength, min, psi, (MPa) 30 000 (205) 30 000 (205) 35 000 (240)
Elongation in 2 in. A,B A,B A,B
  AThe minimum elongation in 2 in. (50.8 mm) shall be that determined by the following equation: 
e = 625 000 A0.2 / U0.9 
 Where: 
e = minimum elongation in 2 in. (50.8 mm) in percent rounded to the nearest 0.5%
A = cross-sectional area of the tension test specimen in square inches, based on specified outside diameter or nominal specimen width and specified wall thickness rounded to the nearest 0.01 in.2 If the area thus calculated is greater than 0.75 in2, then the value 0.75 shall be used, and 
U = specified tesile strength, psi
BSee Table X4.1 for minimus elongation values for various size tension specimens and grades
 
Hydrostatic Testing of ASTM A53 Pipe 
Separate hydrostatic inspection test pressures are specified for plain end, threaded, and coupled A53 steel pipe. Minimum hydrostatic test pressure for NPS 3 and under is 2,500 psi; minimum test pressure for sizes over NPS  3 is 2,800 psi. Pressure must be maintained for a minimum of 5 seconds, for all sizes.
Mechanical Testing of ASTM A53 Pipe
Electric-resistance welded ASTM A53 steel pipe of NPS 8 and larger must be transverse tested. Sending test (cold) is required for STD and XS-NPS 2 and under, and for XXS-NPS 1-1/4 and under. Flatten testing is required for NPS 2 and larger STD and XS A 53 pipe; flatten testing is not required for XXS pipe.
