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 D883. Both materials are identified as "PP" on the product. Note that this is at variance with Abbreviations D1600, 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:

  • ASTM Designation: Title of Specification
  • A 53: Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless (Types E and S)
  • A 106: Seamless Carbon Steel Pipe for High-Temperature Service
  • A 135: Electric-Resistance Welded Steel Pipe
  • A 587: Electric-Welded Low-Carbon Steel Pipe for the Chemical Industry
  • A 312: Seamless and Welded Austenitic Stainless Steel Pipe
  • A 513: Electric-Resistance Welded Carbon and Alloy Steel Mechanical Tubing

1.2.2 For Ferrous Flanges:

  • ASTM Designation: Title of Specification
  • A 48: Gray Iron Castings
  • A 105: Forgings, Carbon Steel, for Piping Components
  • A 126: Gray Iron Castings for Valves, Flanges, and Pipe Fittings
  • A 181: Forgings, Carbon Steel, for General-Purpose Piping
  • A 182: Forged or Rolled Alloy-Steel Pipe Flanges, Forged Fittings, and Valves and Parts for High-Temperature Service
  • A 216: Carbon-Steel Castings Suitable for Fusion Welding for High-Temperature Service (Grade WCB)
  • A 278: Gray Iron Castings for Pressure-Containing Parts for Temperatures Up to 650
