Can a forging that has been machined and bored be certified as meeting the requirements of ASTM A333?

RE: ASTM A333
ASTM A333 is a certification specifying that appropriate steel and alloys were formed into seamless pipe and it is suitable for cold temperatures, so machine boring the pipe does not modify the ASTM A333 specification under which it was originally produced, therefore the machined pipe would still comply with ASTM A333.

Yes, ASME SA 333 does not prohibit it. Also, you can review ASME SA 999 which describes general requirements for Alloy and Stainless Steel pipe. Forged and bored, cast, seamless and welded are all identified.

ASTM A53,
Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless
ASTM A105
Standard Specification for Carbon Steel Forgings for Piping Applications
ASTM A106.
Standard Specification for Seamless Carbon Steel Pipe for High-Temperature Service
For ASTM A333, I see this at www.TechStreet.com

ASTM International 01-Mar-2005 7 pages
----------------------------------------
1.1 This specification covers nominal (average) wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures . Several grades of ferritic steel are included as listed in Table 1. Some product sizes may not be available under this specification because heavier wall thicknesses have an adverse affect on low-temperature impact properties.[/quote]
I don't have a copy of A333, so I can't say how specifically it addresses seamless pipe fabrication process.

RE: ASTM A333
"The pipe shall be made by the seamless or welded process". I'm not sure whether the "seamless process" was meant to include forging and boring even though it is alluded to by association with A999

A-999, 10.2 specifically includes forged and bored pipe as a method of manufacture.

RE: ASTM A333
Agreed. I can only recall a couple of instances when we purchased such pipe. Needed small quantity ASAP; only way to get the material in time to complete the work on schedule. Quite expensive as I recall.

I am in total agreement with the statement above by stanweld. We have purchased pipe that was indeed dual certified to ASME SA 333 and SA 369.

Pilger process, not Pilcher, and SA 335 not SA 333.
