STANDARDS CCTF CAST IRON FITTINGS are designed to conform with the following industry standards: MATERIAL: ASTM A 126 Gray Iron Castings ASTM A 153 Zinc Coatings DIMENSIONS: ANSI/ASME B 16.4 Cast Iron Threaded Fittings ASME B 16.14 Ferrous Pipe Plugs, Bushings, etc. THREADS: ANSI/ASME B1.20.1 Pipe Threads IDENTIFICATION, MARKING Each fitting shall be marked with manufacturer’s name or trademark. Class 125 Cast Iron threaded fittings have no pressure class markings. THREADING All fittings shall be threaded with American National Standard Pipe Threads (ANSI/ASME B1.20.1) and shall have taper threads, except wrought couplings and wrought caps in sizes 1/8, 1/4, 3/8 and 1/2, which may have straight threads. CONVERSION FACTORS The International System (SI) metric equivalent of British units are shown throughout this catalogue. NPS (Nominal Pipe Size) = DN* (Nominal Diameter) Operating Pressure Class = PN* (Pressure Number) 1 inch = 25.4 millimetres 1 pound, weight = 0.4536 kilograms 1 pound, pressure = 0.06895 bars *From the SI designations, Diamètre Nominal and Pression Nominale. 1 14.5 psi = 1 bar = 100 kPa. 2 Permissible for service temperature up to 353?F, reflecting the temperature of saturated steam at 125 psig. *All CCTF iron fittings are air pressure tested under water. *PRESSURE-TEMPERATURE RATINGS CAST IRON - ANSI/ASME B 16.4 Temperature Class 1251 psi Degrees C Degrees F -29 to 66 -200 to 150 175 93 200 165 121 250 150 149 300 140 177 350 1252 ? 4 ?
