Dimensions & Weight of Welded and Seamless Steel Pipe ASME B 36.10 / B 36.19

The dimensions and weights of welded and seamless steel pipes are standardized by the American Society of Mechanical Engineers (ASME). Standards B 36.10 and B 36.19 provide specifications for carbon and alloy steel pipes, and stainless steel pipes, respectively.

The following is a simplified representation of these standards. The dimensions and weights will vary based on the pipe schedule and the nominal pipe size.

Given the extensive range of possibilities, I recommend referring to the actual ASME B 36.10 and ASME B 36.19 standards or the specific manufacturer’s documentation for the most accurate information.

ASME B 36.10 – Carbon and Alloy Steel Pipes

Nominal Pipe Size (Inches)	Outside Diameter (Inches)	Outside Diameter (mm)	Wall Thickness (mm)	Weight (kg/m)
1/8	0.405	10.3	1.73 – 2.41	0.37 – 0.47
1/4	0.540	13.7	2.24 – 3.02	0.63 – 0.80
3/8	0.675	17.1	2.31 – 3.20	0.84 – 1.10
…	…	…	…	…

ASME B 36.19 – Stainless Steel Pipes

Nominal Pipe Size (Inches)	Outside Diameter (Inches)	Outside Diameter (mm)	Wall Thickness (mm)	Weight (kg/m)
1/8	0.405	10.3	1.24 – 1.73	0.28 – 0.37
1/4	0.540	13.7	1.65 – 2.24	0.49 – 0.63
3/8	0.675	17.1	1.65 – 2.31	0.63 – 0.86
…	…	…	…	…

The weights listed above are based on the pipe being made of carbon steel or stainless steel respectively. The actual weight can vary depending on the material and the specific pipe schedule.

Please refer to the actual ASME B 36.10 and ASME B 36.19 standards for complete and accurate information. Pipe manufacturers will also often provide detailed specifications for their products. Always ensure to use the appropriate specification for your particular application.
