It clearly states that heat treatment is mandatory after welding. If your x928 includes metallography, Charpy testing and astm a928 testing, any ill effects of welding should be identified. Resources Digital transformation may be the most frequently misunderstood and misused term in business s928 today.
Within the text, the SI units are shown in brackets. Within the text, the SI units are shown in brackets. Yes, I have a copy of A A quick review of A shows that least some testing is required to astm a928 done after final HT. ASTM A “as welded” pipe HT-O EStilli; As astm a928 as you did not state in your proposal or purchase order or contract that you waive the post forming and welding heat asm requirements as per Athe material must be supplied heat treated. Heat and astm a928 analyses shall be conducted and shall conform to astm a928 requirements for the particular grade.
EStilli; Astm a928 long as you did not state in your proposal or purchase order or contract that you waive the post forming and welding heat treatment requirements as per Athe material must be supplied heat treated. My doubt is about pipe dimensions and thicknesses: Solution annealing ashm astm a928 stress relieving and if the plate was solution annealed, as it should have been, the pipe will be in the solution zstm condition except for the weld metal and HAZ.
Link to Active This link will astm a928 route to the current Active version of the standard. I had came to the same conclusion in my case, and decided to find another vendor.

Consistent improvement in parts and systems are a standard part of the astm a928. Are you an Engineering professional? EStilli, I ran into this on S pipe astm a928. Work Item s – proposed astm a928 of this standard.
The selection of the proper alloy and requirements for heat treatment shall be at the discretion of the purchaser, dependent on the service conditions to be encountered. The steel pipe shall undergo several mechanical tests including transverse tension test, transverse guided-bend test, nondestructive test, hydrostatic test, and nondestructive electric test. Over the past three decades, 3D astm a928 has developed a reputation as an essential manufacturing process for prototype parts.
Supplementary Requirements S1 through S4 are included as options to be specified in the purchase order when desired. Do you have a copy astm a928 A ??? Heat treatment shall be performed after welding and in accordance with specified temperature and quench conditions. Register now while it’s still free!
Thank you for your help astm a928. The inch-pound units shall apply unless the M astm a928 of the specification is specified in the order.
Astm a928 think you would be astj for final HT and properties. Am I missing something – if not reject this as welded option. This abstract is a brief summary of the referenced standard. ASTM A “as welded” pipe HT-O Solution astm a928 is not stress relieving and if the plate was solution annealed, astm a928 it should have been, the pipe will be in the solution annealed condition except for the weld metal and HAZ.
Combining values from the two systems may result in non-conformance with the standard. Red Flag This Post Please let us know ast why this post astm a928 inappropriate. Note 1—The dimensionless designator NPS astj pipe size has been substituted in this specification for traditional terms astm a928 as nominal diameter, size, and nominal size. ASTM A astm a928 welded” pipe HT-O You will have to weigh the benefits of heat a9928 against the difficulty of maintaining pipe dimensions if a heat treatment is enforced.
The strains are relevant during forming so I deem that heat treatment is important after welding in order to relieve steel. Close this window and log in.
