(Specification)Standard Specification for Plastic-Lined Ferrous Metal Pipe, Fittings, and Flanges
Standard Specification for Plastic-Lined Ferrous Metal Pipe, Fittings, and Flanges
ABSTRACT
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.
SCOPE
1.1 This specification covers factory-made plastic-lined ferrous metal pipe, fittings, and flanges intended primarily for conveying corrosive fluids. Requirements for materials, workmanship, dimensions, design, fabrication, working pressure and temperatures, test methods, qualification requirements, and markings are included.
1.1.1 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.
1.1.2 This specification does not include products coated with plastics.
1.2 This specification covers plastic-lined pipe, flanges, and fittings as listed in Table 1. Pressure limitations shall be in accordance with ANSI/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.
Note 1—In this specification, propylene plastics cover those materials defined as both polypropylene plastics and propylene plastics in Terminology F 412. Both materials are identified as “PP” on the product. Note that this is at variance with Terminology D 1600, where “PP” is the abbreviation for polypropylene.
1.3 The plastic-lined flanged pipe and fitting assemblies are limited to temperatures shown in Table 2. End users should consult with manufacturers as to the likely result of using a particular lined piping component at temperatures below the rated minimum.
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 the manufacturer.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
