石油油管螺紋量規(guī)是檢驗石油油管和接箍等連接螺紋的檢驗量具。根據(jù)石油油管的形式，量規(guī)分為不加厚油管螺紋(TBG，NU)和外加厚螺紋(UPTBG,EU)。石油油管螺紋量規(guī)規(guī)格不加厚油管螺紋量規(guī)外加厚螺紋量規(guī)規(guī)格in(mm)扣數(shù)/in(螺距)錐度（in/ft）規(guī)格in(mm)扣數(shù)/in(螺距)錐度（in/ft）1.050(26.7)10(2.54)1:16(3/4)1.050(33.4)10(2.54)1:16(3/4)1.315(33.4)10(2.54)1:16(3/4)1.315(37.3)10(2.54)1:16(3/4)1.660(42.2)10(2.54)1:16(3/4)1.660(46.0)10(2.54)1:16(3/4)1.990(48.3)10(2.54)1:16(3/4)1.900(53.2)10(2.54)1:16(3/4)23/8(60.3)10(2.54)1:16(3/4)23/8(65.9)8(3.175)1:16(3/4)27/8(73)10(2.54)1:16(3/4)27/8(78.6)8(3.175)1:16(3/4)31/2(88.9)10(2.54)1:16(3/4)31/2(95.3)8(3.175)1:16(3/4)4(101.6)8(3.175)1:16(3/4)4(107.9)8(3.175)1:16(3/4)41/2(114.3)8(3.175)1:16(3/4)41/2(120.6)8(3.175)1:16(3/4)
