What’s ASTM F1545?

It’s Standard Specification for Plastic-Lined Ferrous Metal Pipe, Fittings, and Flanges

This specification covers factory-made plastic-lined ferrous metal pipe, fittings, and flanges for conveying corrosive fluids. Lining material shall be made from a resin that conforms to the requirements of this specification. Other requirements include mechanical properties, specific gravity, finish, dimensions, design, working pressure, working temperature, flange construction, venting, workmanship, performance, quality, marking, and packaging. High-temperature test, low-temperature test, steam-cold water cycling test, vacuum test, hydrostatic pressure test, and electrostatic test shall be done in accordance to the procedures of this specification.

This specification does not define the suitability of different liner materials to various chemical and operating environments. Refer to the manufacturer’s chemical resistance data for suitability recommendations.

This specification does not include products coated with plastics.

This specification covers plastic-lined pipe, flanges, and fittings as listed in Table 1. Pressure limitations shall be in accordance with ASME B16 Standards, except reduced pressure limitations may be established by the manufacturer, considering both pressure and temperature limitations of the ferrous metal housing and the sealing ability of the liner.
