Standard Specification for Welded Large Diameter Austenitic Steel Pipe for Corrosive or High-Temperature Service
STANDARD published on 1.3.2024
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This guide covers standard specification for straight seam or spinal seam electric-fusion-welded, light-wall, austenitic chromium-nickel alloy steel pipe for corrosive or high-temperature service. The sizes covered shall include NPS 14 to 30 with extra light (Schedule 5S) and light (Schedule 10S) wall thickness. Several grades of alloy steel shall be covered and shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, titanium, columbium, cerium, and other elements. The chemical composition of the welding filler metal shall also conform to the requirements of the applicable AWS specification for the corresponding grade. Tensile properties of the plate or sheet used in making the pipe shall conform to the prescribed values of tensile strength and yield strength. Mechanical tests such as tension test and transverse guided-bend weld test shall be conducted. Pressure or nondestructive electric test shall also be performed.
