Abstract

This Standard specifies steel pipe flanges (hereafter referred to as "flanges") of nominal sizes 10 A to 1 500 A for nominal pressures 5 K, 10K, 10K light type, 16K, 20K, 30K, 40K and 63K which are used to join parts for piping, such as steel pipes and valves used for ordinary piping ¹⁾, pressure piping ²⁾, high pressure piping ³⁾, high temperature piping ⁴⁾, alloy steel piping ⁵⁾ and stainless steel piping ⁶⁾ for steam, air, gas, water, oil, etc. <br>This Standard is also applicable to flanges which are integral with the piping part, and constituting a part thereof (hereafter referred to as the "integral flanges"). <br>NOTE 1: The outside diameters of <strong>JIS</strong> steel pipes are shown in Annex B. <br>NOTE 2: All the pressure values indicated in this Standard are of the gauge pressure. <br>Notes ¹⁾ Piping using carbon steel pipes for ordinary piping of <strong>JIS G 3452</strong> and arc welded carbon steel pipes of <strong>JIS G 3457</strong>. <br>²⁾ Piping using carbon steel pipes for pressure service of <strong>JIS G 3454</strong>. <br>³⁾ Piping using carbon steel pipes for high pressure service of <strong>JIS G 3455</strong>. <br>⁴⁾ Piping using carbon steel pipes for high temperature service of <strong>JIS G 3456</strong>. <br>⁵⁾ Piping using alloy steel pipes of <strong>JIS G 3458</strong>. <br>⁶⁾ Piping using stainless steel pipes of <strong>JIS G 3459</strong> and large diameter welded stainless steel pipes of <strong>JIS G 3468</strong>.
