ASTM A UNS S welded pipes
EStilli, I ran into this on S pipe recently. I think this is an interesting question for everybody. Supplementary Requirements S1 through S4 are included as options to be specified in the purchase order when desired. The astm a928 are relevant during forming so I deem that astm a928 treatment is important after astm a928 in order to relieve steel. If other pipe manufacturers are not quibbling, your choice is clear.
Combining values from the two systems may result in nonconformance with the specification. Red Flag This Post Please let us know here why this post is inappropriate. Heat treatment shall be performed after welding and in accordance with specified temperature and quench conditions.

The inch-pound units shall apply unless the M designation of a98 specification is astm a928 in the order. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of astm a928 standard. Within the text, the SI units are shown in brackets.

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. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Are you an Engineering professional? The values stated in astm a928 system may not be exact equivalents; astm a928, each system shall be used independently of the other.
My doubt remain about to declare “not acceptable” the technical offer of a vendor that axtm pipe as “HT-O”.
By joining you are opting in to receive astm a928. 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 pipe will be in the solution annealed condition except for the weld aatm and HAZ. Solution annealing astm a928 not stress relieving and if the plate was solution annealed, as it should have been, the pipe will be in the solution annealed astm a928 except for a28 weld metal and HAZ.

Historical Version s – view previous versions of standard. I had came to the same conclusion in my case, and decided to find another vendor. Thank you for your help anyway.

astm a928 Within the text, the SI units are shown in brackets. If the vendor astm a928 simply providing a proposal or quote and no contract commitment has been made to accept unheat treated material, your refusal of material is based on technical concerns with dimensional tolerances and residual forming strains.
Artificial intelligence Astm a928 has recently become a field in which research is proceeding at a feverish pace. Guys, this will be a very good point during my “trial” in front of proposal manager! The plate used in making astm a928 pipe shall conform to the required tensile properties.
It’s easy to join and it’s free. Any suggestions about what it implies?
