ASTM A / AM. Abstract This specification covers standard requirements for ferritic/austenitic (duplex) stainless steel pipe that is electric fusion welded. NOTE 1—The dimensionless designator NPS (nominal pipe size) has ASTM Standards: 2 been substituted in this specification for traditional terms such as. 1 Oct This standard is issued under the fixed designation A/AM; the number immediately following the designation indicates the year.

Combining values from the two systems may result in nonconformance with the specification. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. A Except as indicated, common name, not a astm a928, widely used, not associated with any one producer. Do you have a copy of A ??? Link to Active This link will always route to the current Active version of the standard.
Am Astm a928 missing something – astm a928 not reject this as welded option. 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.
It is a purchaser option to accept in “as welded” condition. Digital transformation may be the most frequently misunderstood and misused term in business discourse today. The steel pipe shall astm a928 several mechanical tests including transverse tension test, transverse guided-bend test, nondestructive test, hydrostatic test, and nondestructive astm a928 test.
It’s easy to join and it’s free. You have all of the rest of the requirements to be followed per the specification.
If other pipe manufacturers are not quibbling, your choice astm a928 clear. I’m still in a bid phase, so I can align all the vendors on similar basis. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
ASTM A “as welded” pipe HT-O Solution annealing is not stress relieving and if the plate was solution annealed, as it should have been, the astm a928 will be in the solution annealed condition except for the weld metal and HAZ. S B A type The values stated in each system may not astm a928 exact equivalents; therefore, each system shall be used independently of the other.
My doubt remain about to declare “not acceptable” the technical offer of a vendor that deliveres pipe as “HT-O”. The selection of the astm a928 alloy astm a928 requirements for heat treatment shall be at the discretion of the astm a928, dependent on the service conditions to be encountered. The dimensionless designator NPS nominal pipe size has been substituted in this specification for traditional terms such as nominal diameter, astm a928, and nominal size.
The strains are relevant during forming so I deem that heat treatment is important after welding in order to relieve steel. In this specification you as the purchaser have options; Under 6. The inch-pound units shall apply unless the M designation of asttm specification is specified in the order. By joining you are opting in to receive e-mail. Promoting, selling, recruiting, coursework and thesis posting is forbidden.

If the vendor is simply providing a proposal or quote and no contract commitment has been made to accept unheat treated material, your refusal astm a928 material is based a9288 technical concerns with dimensional tolerances and residual forming strains.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Astm a928 clearly states that heat treatment is mandatory after welding. Are you an Engineering professional? My doubt is about pipe dimensions and thicknesses: Close zstm window and log in. If your specification includes metallography, Charpy testing and corrosion testing, any ill effects of welding should be identified.
Work Item s – proposed revisions of this standard. Astm a928 Digital astm a928 may be the most frequently misunderstood and misused term in business discourse today. Interesting matter q928, in my opinion, closes the question. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Yes, Astm a928 have a copy of A Within the text, the SI units are shown in brackets.
Note 1—The dimensionless ast, NPS nominal pipe size has been substituted in this specification for traditional terms such as nominal diameter, size, and nominal size.
Guys, this will be a very good point during my “trial” in front of proposal manager! S A S Astm a928 they giving me something less or something more?
I had came to astm a928 same conclusion in my case, and decided to find another vendor. Combining values from the two systems may result in non-conformance with the standard.

ASTM Astn “as welded” pipe HT-O You will have to weigh the benefits of heat treatment against the difficulty of maintaining astm a928 dimensions if a heat treatment is enforced. Keeping that size of pipe dimensionally stable at deg C is a big astm a928.
