【国外标准】 Standard Specification for Poly(Vinylidene Chloride) (PVDC) Plastic-Lined Ferrous Metal Pipe and Fittings (Withdrawn 2004)

1.1 This specification covers factory-made poly(vinylidene chloride) (PVDC) plastic-lined ferrous metal pipe and fittings primarily intended for conveying corrosive liquids and gases. Requirements for materials, workmanship, dimensions, construction, working pressure and temperatures, test methods, and markings are included. Note 1-This specification does not include products coated with PVDC nor does it define the suitability of PVDC-lined components in chemical environments. 1.2 The values given in parentheses are provided for information purposes only. 1.3 The ferrous piping products shall meet the requirements of the relevant specifications listed in 1.3.1, 1.3.2, and 1.3.3. Nominal sizes from 1 through 8 in. in 125, 150, and 300 psi ratings are covered. Note 2-The PVDC sealing faces may prevent achievement of the full pressure rating of the ferrous housing. For pressure limitations, the manufacturer should be consulted. 1.3.1 For Ferrous Pipe: ASTM Title of Specification Designation Pipe, Steel, Black, and Hot-Dipped, Zinc-Coated, Welded and Seamless A 53 Seamless Carbon Steel Pipe for High-Temperature Service A 106 Electric-Resistance-Welded-Carbon and Alloy Steel Mechanical Tubing A 513 Electric-Resistance-Welded Steel Pipe A 135 Electric-Welded Low-Carbon Steel Pipe for the Chemical Industry A 587 1.3.2 For Ferrous Flanges: ASTM Title of Specification Designation Gray Iron Castings A 48 Forgings, Carbon Steel for Piping Components A 105 Gray Iron Castings for Valves, Flanges, and Pipe Fittings A 126 Forgings, Carbon Steel for General Purpose Piping 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 A 216 Gray Iron Castings for Pressure-Containing Parts for Temperatures up to 650
