【国外标准】 Standard Specification for High-Silicon Iron Pipe and Fittings

This specification covers high-silicon iron pipe and pipe fittings intended for corrosion-resistant service for both above- and below-grade construction. The castings shall be true to pattern, reasonable smooth, and free from defects that would make the castings unfit for the use for which they are intended. The material shall conform to the chemical composition requirements specified. All centrifugally cast high-silicon iron pipe shall be supplied in the as-cast condition. All other pipe and fittings shall be supplied in the stress-relieved condition; the stress relieving procedures are presented. Acid-proof joints for hub/plain-end pipe shall require the use of an acid-proof rope packing. No-hub pipe and fittings shall require a special acid resistant mechanical joint coupling. High-silicon iron pipe can be cut with either manual or hydraulic snap cutters. Hydrostatic testing shall be conducted on all castings.1.1 This specification covers high-silicon iron pipe and pipe fittings intended for corrosion-resistant service for both above- and below-grade construction.1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.3 Pipe and pipe fittings shall be the no-hub (MJ) or the hub and plain-end design.1.4 Pipe and pipe fittings shall be of the sizes specified in Table 1 and Table 2 and Figs. 1–71 or other sizes that shall be permitted to conform to the requirements given herein.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.NOTE 1: Flange dimensions are 150 lb ANSI standard.NOTE 2: 1 in. = 25.4 mm.NOTE 1: 1 in. = 25.4 mm.Size, in. t, in.
