Scope

1.1 This specification covers factory-made propylene and polypropylene (PP) 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—In this specification, propylene plastics cover those materials defined as both polypropylene plastics and propylene plastics in Definitions D 883. Both materials are identified as “PP” on the product. Note that this is at variance with Abbreviations D 1600, where PP is the abbreviation for polypropylene. NOTE 2—This specification does not include products coated with PP nor does it define the suitability of PP-lined components in chemical environments. 1.2 The ferrous piping products shall meet the requirements of the relevant specifications listed in 1.2.1. Nominal sizes from 1⁄2 through 12 in. in Class 125, 150, and 300-psi are covered. NOTE 3—The PP sealing faces may prevent achievement of the full pressure rating of the ferrous housings. For pressure limitations, the manufacturer should be consulted. NOTE 4—Flanged fittings are not available in sizes 1⁄2 and 3⁄4. 1.2.1 For Ferrous Pipe: Title of Specification ASTM 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 513 1.2.2 For Ferrous Flanges: Title of Specification ASTM 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 Title of Specification ASTM Designation 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 HighTemperature Service (Grade WCB). A 216 Gray Iron Castings for Pressure-Containing Parts for Temperatures Up to 650°F (345°C) A 278 Ferritic Ductile Iron Pressure-Retaining Castings for Use at Elevated Temperatures (60-40-18) A 395 Ductile Iron Castings (60-40-18, 65-45-12, 80-55-06) A 536 1.2.3 For Ferrous Fittings: Title of Specification ASTM 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 Carbon Steel Castings Suitable for Fusion Welding for HighTemperature Service (Grade WCB) A 216 Piping Fittings of Wrought Carbon Steel and Alloy for Moderate and Elevated Temperatures Steel Welding Fittings A 234 Gray Iron Castings for Pressure-Containing Parts for Temperatures up to 650°F (345°C) A 278 Austenitic Steel Castings for High-Temperature Service A 351 Alloy Steel Castings Specially Heat-Treated for PressureContaining 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 403 1.3 The PP-lined flanged pipe and fitting assemblies are limited to use from −18 to 107°C (0 to 225°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. 1.4 The values stated in inch-pound units are to be regarded as the standard.
