ASTM A105/A105M-18 pdf free download.Standard Specification for Carbon Steel Forgings for Piping Applications.
1.1 This specification 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 specilications referenced in Section 2. Forgings made to this specification are limited to a maximum weight of 10 000 lb 14540 kg]. Larger forgings may be ordered to Specification A266/A266M. Tubeshects 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). ii does not cover raw material produced in these product forms.
1 .2 Supplementary requirements are provided for use when additional testing or inspection is desired. These shall apply only when specified individually by the purchaser in the order.
1 .3 Specification A266/A266M covers other steel forgings and Specifications A675/A675M and A696 cover other steel bars.
1 .4 This specification is expressed in both inch-pound units and SI units. However, unless the order specifies the applicable 6"M” specification designation (SI units), the material shall be furnished to inch-pound units. The values stated in either SI units or inch-pound units are to he regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents:
therefore, each system shall be used independently of the other.
5. General Requirements
5.1 Product furnished to this specification shall conform to the requirements of Specification A%l/A961 M, 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 specification. 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 A78/
A788M.
6. Heat Treatment
6.1 Heat treatment is not a mandatory requirement of this specification except for the following piping components:
6.1.1 Flanges above Class 3OO,
6.1.2 Flanges of special design where the design pressure at the design temperature exceeds the pressure-temperature ratings of Class 300. Group 1.1.
6.1.3 Flanges of special design where the design pressure or design temperature are not known.ASTM A105/A105M pdf download.
