Standard Specification for Propylene and Polypropylene (PP) Plastic-Lined Ferrous Metal Pipe and Fittings (Withdrawn 2004)

ASTM F492 – Standard Specification for Propylene and Polypropylene (PP) Plastic-Lined Ferrous Metal Pipe and Fittings (Withdrawn 2004)

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 productscoatedwith 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 from1/2 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 sizes1/2 and3/4.
