Material and Manufacturing StandardsThe manufacture of welding fittings is governed by industry standards established by such associations as 1) the American Societyfor Testing and Materials (ASTM): 2) the American National Standards Institute (ANSI): 3) the Manufacturer’s StandardizationSociety of the Valve and Fittings Industry (MSS): 4) the Pipe Fabrication Institute (PFI): and 5) the Canadian Standards Association(CSA). They cover specifications for materials, methods of manufacture, dimensions and quality control procedures. All CCTFwelding fittings conform to one or more of these standards.ASTM STANDARDSCCTF carbon steel welding fittings are manufactured from seamless steel tubing and furnished in accordance with ASTM Standard A-234,with material specifications in accordance with ASTM A-106, Grade B, for fittings made from pipe; ASTM A-515, Grade 65 or 70, for fittingsmade from plate.CCTF alloy steel welding fittings are furnished in accordance with ASTM standard A-234, with materials specification including A-335, GradeP1, carbon-molybdenum, and Grade P12, P11, P22, P5, P7; P9 chrome molybdenum, for fittings made from pipe.ASTM A-204 Grade B, carbon molybdenum, and ASTM A-387 Grades 12, 11, 22, 5, 7, 9 chrome molybdenum for fittings made from plate.CCTF welding fittings are also available in accordance with ASTM specification A-420 covering low-temperature service, down to -150 F(-101 C).CCTF stainless steel welding fittings are manufactured and available in the following types: 304, 304L, 316, 316L and 347. They arefurnished in accordance with ASTM Standard A-403, with material specifications to ASTM A-312 covering fittings made from pipe, and A-240for fittings made from plate. Refer to CCTF catalogue “Stainless Steel Welding Fittings.ANSI, MSS, ASME and CSA StandardsASME/ANSI and MSS standards govern fitting dimensions and tolerances, ASME/ANSI B16.9 “Wrought Steel Buttwelding Fittings”, si thebasic standard. It covers steel butt-welding fittings sizes NPS 1/2 through NPS 48 (DN 15 through DN 1200).Other ASME/ANSI and MSS standards, written to supplement B16.9, are as follows:ASME/ANSI B16.25:Butt-welding EndsASME/ANSI B16.28:Butt-welding short radius elbows and returnsMSS SP-43:Light-wall stainless steel fittings, NPS 3/4 through NPS 24 (DN 20 through DN 600)MSS SP-75:High Test Wrought Welding FittingsThe following codes andASME/ANSI B31.1:ASME/ANSI B31.3:ASME/ANSI B31.4:ASME/ANSI B31.5:ASME/ANSI B31.8:ANSI/ASME B36.10M:ANSI/ASME B36.19M:CSA Z183:CSA Z184:CAN3-Z245.11-M91:ASME:standards influence the manufacture of welding fittings, where applicable.Power pipingPetroleum refinery pipingLiquid petroleum transportation piping systemRefrigeration pipingGas transmission and distribution piping systemsWelded and seamless wrought steel pipeStainless steel pipeOil pipe line transportation systemsGas pipe line systemsRequirements for wrought steel butt welding fittingsBoiler and pressure vessel codeSPECIAL METALSHigh Test Steel. High test pipe line welding fittings, conforming to CSA Standard CAN3-Z245.11 or MSS SP-75, are available with physicalproperties to match pipe with *42,000, 46,000, 52,000, 60,000, 65,000, and over p.s.i. minimum yield strengths.Other Ferrous Alloys. Fittings are available manufactured from ASTM alloy specifications other than those listed in the “ASTM Standards”above.Non-Ferrous Metals. Fittings of relatively common metals, such as aluminum, nickel, copper, etc., can be readily furnished; production islimited only be availability of raw materials. The same is true of less common metals, such as the various grades of Hastelloy, Inconel,Incoloy, Monel, Alloy-20, rare types of stainless steel and other unusual analyses.*Equals 290, 317, 359, 414, 448 Mpa, respectively.METRIC EQUIVALENTSThe 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 millimetres1 pound, weight 0.4536 kilograms1 psi 0.06895 bars1 psi, stress 0.006895 megapascals (MPa) From the SI designations, Diamètre Nominal and Pression Nominale. 4
