1、Designation: D2241 09An American National StandardStandard Specification forPoly(Vinyl Chloride) (PVC) Pressure-Rated Pipe (SDRSeries)1This standard is issued under the fixed designation D2241; the number immediately following the designation indicates the year oforiginal adoption or, in the case of
2、 revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specific
3、ation covers poly(vinyl chloride) (PVC)pipe made in standard thermoplastic pipe dimension ratios andpressure rated for water (see appendix). Included are criteriafor classifying PVC plastic pipe materials and PVC plasticpipe, a system of nomenclature for PVC plastic pipe, andrequirements and test me
4、thods for materials, workmanship,dimensions, sustained pressure, burst pressure, flattening, andextrusion quality. Methods of marking are also given.1.2 The products covered by this specification are intendedfor use with the distribution of pressurized liquids only, whichare chemically compatible wi
5、th the piping materials. Due toinherent hazards associated with testing components and sys-tems with compressed air or other compressed gases, somemanufacturers do not allow pneumatic testing of their products.Consult with specific product/component manufacturers fortheir specific testing procedures
6、 prior to pneumatic testing.NOTE 1Pressurized (compressed) air or other compressed gasescontain large amounts of stored energy which present serious safetyhazards should a system fail for any reason.NOTE 2This standard specifies dimensional, performance and testrequirements for plumbing and fluid ha
7、ndling applications, but does notaddress venting of combustion gases.1.3 The text of this specification references notes, footnotes,and appendixes which provide explanatory material. Thesenotes and footnotes (excluding those in tables and figures) shallnot be considered as requirements of the specif

The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.5 The following safety hazards caveat pertains only to thetest methods port
9、ion, Section 8, of this specification: Thisstandard does not purport to address all of the safety concerns,if any, associated with its use. It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-ti
10、ons prior to use. A specific precautionary statement is givenin Note 7.NOTE 3CPVC plastic pipe (SDR-PR), which was formerly includedin this specification, is now covered by Specification F442/F442M.NOTE 4The sustained and burst pressure test requirements, and thepressure ratings in the appendix, are
11、 calculated from stress values obtainedfrom tests made on pipe 4 in. (100 mm) and smaller. However, testsconducted on pipe as large as 24 in. (600 mm) in diameter have shownthese stress values to be valid for larger diameter PVC pipe.NOTE 5PVC pipe made to this specification is often belled for use

Terminology
20、3.1 DefinitionsDefinitions are in accordance with Termi-nology F412, and abbreviations are in accordance with Termi-nology D1600, unless otherwise specified.The abbreviation forpoly(vinyl chloride) plastic is PVC.3.2 Definitions of Terms Specific to This Standard:3.2.1 hydrostatic design stressthe e
21、stimated maximumtensile stress the material is capable of withstanding continu-ously with a high degree of certainty that failure of the pipewill not occur. This stress is circumferential when internalhydrostatic water pressure is applied.3.2.2 pressure rating (PR)the estimated maximum waterpressure
22、 the pipe is capable of withstanding continuously witha high degree of certainty that failure of the pipe will not occur.3.2.3 relation between standard dimension ratio, hydro-static design stress, and pressure ratingThe following ex-pression, commonly known as the ISO equation,4is used inthis speci
23、fication to relate standard dimension ratio, hydrostaticdesign stress, and pressure rating:2S/P 5 R 2 1 or 2 S/P 5 D0/t! 2 1 (1)where:S = hydrostatic design stress, psi (or MPa),P = pressure rating, psi (or MPa),D0= average outside diameter, in. (or mm),t = minimum wall thickness, in. (or mm), andR
24、= standard thermoplastic pipe dimension ratio (D0/t forPVC pipe), also known as SDR.3.2.4 standard thermoplastic pipe dimension ratio (SDR)the ratio of pipe diameter to wall thickness. For PVC pipe it iscalculated by dividing the average outside diameter of the pipein inches or millimetres by the mi
25、nimum wall thickness ininches or millimetres. If the wall thickness calculated by thisformula is less than 0.060 in. (1.52 mm), it shall be arbitrarilyincreased to 0.060in. (1.52 mm). The SDR values shall berounded to the nearest 0.5.3.2.5 standard thermoplastic pipe materials designationcodeThe pip
26、e materials designation code shall consist of theabbreviation PVC for the type of plastic, followed by theASTM type and grade inArabic numerals and the design stressin units of 100 psi (0.7 MPa) with any decimal figures dropped.When the design stress code contains less than two figures, acipher shal
27、l be used before the number, thus a completematerial code shall consist of three letters and four figures forPVC plastic pipe materials.4.
