ASTM A105/A105M-18 pdf free download.Standard Specification for Carbon Steel Forgings for Piping Applications.
ASTM A105/A105M-18 covers forged carbon steel piping components for ambient- and higher-temperature service in pressure systems. Included are flanges, fittings, valves, and similar parts ordered either to dimensions specified by the purchaser or to dimensional standards such as the MSS, ASME, and API specifications referenced in Section 2. Forgings made to this specification are limited to a maximum weight of 10 000 lb [4540 kg]. Larger forgings may be ordered to Specification A266/A266M. Tubesheets and hollow cylindrical forgings for pressure vessel shells are not included within the scope of this specification. Although this specification covers some piping components machined from rolled bar and seamless tubular products (see 5.2), it does not cover raw material produced in these product forms.
5. General Requirements
5.1 Product furnished to this specification shall conform to the requirements of Specification A961/A961M, including any supplementary requirements that are indicated in the purchase order. Failure to comply with the requirements of Specification A961/A961M constitutes nonconformance with this specifica tion. In case of a conflict between the requirements of this specification and Specification A961/A961M, this specification shall prevail.
5.2 Except as permitted by Section 6 in Specification A961/A961M, the finished product shall be a forging as defined in the Terminology Section of Specification A788A788M.
9. Hydrostatic Tests
9. 1 Such tests shall be conducted by the forging manufac- turer only when Supplementary Requirement S57 in Specification A961/A961M is specified.
10. Retreatment
10.1 If the results of the mechanical tests do not conform to the requirement specified, the manufacturer may heat treat or reheat treat the forgings as applicable and repeat the test specified in Section 8.
