1.1 This specification covers factory-made poly(vinylidene fluoride) (PVDF) plastic-lined ferrous metal pipe and fittings, primarily intended for conveying corrosive liquids and gases. Requirements for materials, workmanship, dimensions, design, construction, working pressures and temperatures, test methods, and markings are included. Note 1-This specification does not include products coated with PVDF nor does it define the suitability of PVDF-lined components in chemical environments.1.2 The ferrous piping products shall meet the requirements of the relevant specification listed in 1.2.1. Nominal sizes from 1 through 10 in. in 150 and 300-psi ratings are covered. 1.2.1 For Ferrous Pipe: ASTM Title of Specification Designation Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless (Types E and S) A 53 Seamless Carbon Steel Pipe for High-Temperature Service A 106 Electric-Resistance Welded Steel Pipe A 135 Electric-Welded Low-Carbon Steel Pipe for the Chemical Industry A 587 Seamless and Welded Austenitic Stainless Steel Pipe A 312 Electric-Resistance Welded Carbon and Alloy Steel Mechanical Tubing A 5131.2.2 For Ferrous Flanges: ASTM Title of Specification Designation Forgings, Carbon Steel, for Piping Components A 105 Forged or Rolled Steel Pipe Flanges, Forged Fittings and Valves and Parts for General Service A 181 Forged or Rolled Alloy-Steel Pipe Flanges, Forged Fittings, and Valves and Parts for High-Temperature Service A 182 Carbon-Steel Castings Suitable for Fusion Welding for High-Temperature Service (Grade WCB) A 216 Ferritic Ductile Iron Pressure Retaining Castings for Use at Elevated Temperatures (60-40-18) A 395 Ductile Iron Castings (60-40-18, 64-45-12, 80-55-06) A 5361.2.3 For Ferrous Fittings: ASTM Title of Specification Designation Forgings, Carbon Steel, for Piping Components A 105 Forged or Rolled Steel Pipe Flanges, Forged Fittings, and Valves and Parts for General Service A 181 Carbon Steel Castings Suitable for Fusion Welding for High-Temperature Service (Grade WCB) A 216 Piping Fittings of Wrought Carbon Steel and Alloy Steel for Moderate and Elevated Temperatures A 234 Austenitic Steel Castings for High-Temperature Service A 351 Alloy Steel Castings Specially Heat-Treated for Pressure-Containing Parts Suitable for High-Temperature Service A 389 Ductile Iron Castings (60-40-18, 64-45-12, 80-55-06) A 536 Ferritic Ductile Iron Pressure Retaining Castings for Use at Elevated Temperatures (60-40-18) A 395 Wrought Austenitic Stainless Steel Piping Fittings A 4031.3 The PVDF-lined flanged pipe and fitting assemblies are limited to use from -18 to 135°C (0 to 275°F). For use below -18°C (0°F) consult the manufacturer. Use in specific aggressive environments may alter the above temperature range. The operating temperature limits shall be established by mutual agreement between the purchaser and the seller. |
