One-Minute Overview

Steel pipe dimensioned to the ASME B36.10M standard for welded and seamless sizes.
1/2 to 48 inch with schedules from SCH10 to SCH160 on the standard table.
Wall thickness and outside diameter follow the standard, not a shop guess.
Used across utility, process and power piping where dimensions must be interchangeable.

ASME B36.10 is the dimension standard for welded and seamless carbon and alloy steel pipe, and ordering to it means outside diameter, wall thickness and schedule names all come from the same table. This page covers pipe within that standard, 1/2 to 48 inch, with walls from SCH10 to SCH160. Because the dimensions are fixed by the standard, a length replaced years later still matches the line, and fittings, flanges and valves ordered to their own standards line up without field machining.

Name: ASME B36.10 Pipe
Type: Seamless or Welded
Size: 1/2 to 48 Inch
Schedule: SCH10 to SCH160
Material: Carbon Steel, Alloy Steel
Standard: ASME B36.10M
Feature: Wall Thickness and Outside Diameter per Standard Table
Size, schedule and material are confirmed per inquiry, and a detailed specification sheet is available on request.

The value of buying to ASME B36.10M shows up at the joint. A schedule sets the wall for a given outside diameter, so a spool designed on one continent fits a valve built on another, and the hydraulic calculations survive contact with the real pipe. Check the schedule against the design pressure and temperature, remember that the same schedule number means different walls at different diameters, and order the length and end preparation the fabrication drawing calls for.

Dimensional control continues with the tolerances the standard places on wall, diameter and length, and with marking that identifies material, size and heat. On receipt, verify the marking, spot-check wall and outside diameter, and keep the certification with the material. Seamless and welded versions share the dimension table, so the choice between them turns on pressure, fatigue and the service fluid rather than on fit. End preparation and length are ordered to the fabrication drawing, so the spool closes without rework.

FAQ

Q1. What does a schedule number actually control on this pipe?

It controls the wall thickness for a given outside diameter. SCH40 at 2 inch is not the same wall as SCH40 at 24 inch, which surprises people who treat the number as a wall. Read the wall from the ASME B36.10M table for the actual diameter you are buying.

Q2. If the dimensions match, does it matter whether the pipe is seamless or welded?

Dimensions are only half the story. Seamless has no weld seam, which helps under pressure cycling and fatigue. Welded pipe is cheaper and perfectly fine for steady utility duty. Match the construction to the service, not just to the size chart on the wall.

Q3. Why do engineers get so excited about a table of pipe sizes?

Because that table is the reason a valve from one supplier meets a pipe from another at the joint. Interchangeability is unglamorous and completely essential. Celebrate it quietly with a well-ordered pipe rack and zero field machining on site; that quiet success is what the table buys you.

Q4. What's the minimum I can order for ASME B36.10 pipe?

Standard flange insulation gasket kits start at one set, and standard gaskets, studs, washers and sleeves start at one piece. Kits made to your drawing or for a non-standard bolt pattern are quoted individually, because the minimum really depends on the material and the tooling involved.
