2、last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers factory-made plastic-lined ferrous metal pipe, fittings, and flanges intended primarily for
3、conveying corrosive fluids. Requirements for materials, workmanship, dimensions, design, fabrication, working pressure andtemperatures, test methods, qualification requirements, and markings are included.1.1.1 This specification does not define the suitability of different liner materials to various
4、 chemical and operatingenvironments. Refer to the manufacturers 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 limi
5、tations shall be inaccordance withANSI/ASMEASME 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 1In this specification, propylene pla
6、stics cover those materials defined as both polypropylene plastics and propylene plastics in TerminologyF412. Both materials are identified as “PP” on the product. Note that this is at variance with Terminology D1600, where “PP” is the abbreviation forpolypropylene.1.3 The plastic-lined flanged pipe
7、 and fitting assemblies are limited to temperatures shown in Table 2. End users should consultwith manufacturers as to the likely result of using a particular lined piping component at temperatures below the rated minimum.NOTE 2The temperature limitations are based on noncorrosive test conditions. U
8、se in specific aggressive environments may alter temperaturelimitations. 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 pa
9、rentheses are mathematicalconversions 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 responsibilityof the user of this standard to establish approp
