The values stated in eachsystem are not exact equivalents; therefore, each system mustbe used independently of th
10、e other. Combining values from thetwo systems may result in nonconformance with the specifi-cation. The inch-pound units shall apply unless the “M”designation (SI) of the product specification is specified in theorder.NOTE 1The dimensionless designator NPS (nominal pipe size) hasbeen substituted in

There shall be no variation over the specified insidediameter.11. Permissible Variations in Outside Diameter11.1 Variations
37、 in outside diameter, unless otherwise speci-fied, shall not exceed the limits prescribed in Table 2. Thetolerances on outside diameter include ovality except asprovided for in 11.211.2 Thin-wall pipe usually develops significant ovality(out-of-roundness) during final annealing, straightening, orbot
38、h. The diameter tolerances of Table 2 are not sufficient toprovide for additional ovality expected in thin-wall pipe andare applicable only to the mean of the extreme (maximum andminimum) outside diameter readings in any one cross-section.However, for thin-wall pipe the difference in extreme outside
39、diameter readings (ovality) in any one cross-section shall notexceed 1.5 % of the specified outside diameter.12.

Standard Weight13.1 A system of standard pipe sizes has been approved bythe American National Standards Institute as ANSI B 36.10and B 36.19. These standard sizes do not prohibit the produc-ti
42、on and use of other sizes of pipe produced to the variousspecifications referenced to this Specification.13.2 For nonstandard sizes of pipe, the calculated weightper foot, shall be determined from the following equation:W 5 CD 2 t!t (1)where:C = 10.69 0.0246615,W = weight, lb/ft kg/m,D = specified o
43、r calculated (from specified inside diameterand wall thickness) outside diameter, in. mm, andt = specified wall thickness, in. (to 3 decimal places) mmto 2 decimal places.NOTE 2The weights given in the American National Standards andthe calculated weights given by Eq 1 are based on the weights for c

Ends14.1 Unless otherwise specified, the pipe shall be furnishedwith plain ends. All burrs at the ends of the pipe shall

Straightness15.1 The finished pipe shall be reasonably straight.15.2 For metal-arc welded pipe, the maximum deviationfrom a 10-ft 3.0-m straightedge placed so that both ends arein contact with the pipe shall be18 in. 3.2 mm. For metal-arcwelded pipe with lengths shorter than 10 ft 3.0
46、m, thismaximum deviation shall be pro-rated with respect to the ratioof the actual length to 10 ft 3.0 m.16.
