Organization: ASTM International
Publication Date: 10 September 1995
Status: inactive
Page Count: 5
ICS Code (Iron and steel pipes): 23.040.10
ICS Code (Metal fittings): 23.040.40
scope:

1.1 This specification covers factory-made polytetrafluoroethylene (PTFE) plastic-lined ferrous metal pipe, fittings, and flanges primarily intended for conveying corrosive fluids. Included are requirements for material, workmanship, dimensions, working pressure and temperature, design, fabrication, test methods, marking, as well as qualification requirements.

Note 1-This specification does not include products coated with PTFE.

1.2 This specification covers ANSI Class 150 and 300 PTFE-lined pipe, flanges, and fittings in nominal diameters of 1/2 to 24 in. Pressure limitations shall be those established by the manufacturer considering both pressure and temperature limitations of the ferrous metal housings and sealing ability of the linear at flanged joints.

1.3 The PTFE-lined flanged pipe and fitting assemblies are limited for use from -20 to 500°F (-29 to 260°C). For use below -20°F (-29°C) consult the manufacturer.

Note 2-The temperature limitations are based on noncorrosive test conditions. Use in specific aggressive environments may alter temperature limitations. In such instances, specific temperature limits shall be established by mutual agreement between the purchaser and manufacturer.

1.4 The values given in parentheses are provided for information purposes only.
