石油套管螺紋量規(guī)是檢驗(yàn)石油套管和接箍等連接螺紋的檢驗(yàn)量具。根據(jù)石油套管的形式，量規(guī)分為套管園螺紋(CSG,LCSG)和套管偏梯型螺紋(BCSG)。 石油套管螺紋量規(guī)規(guī)格套管圓螺紋量規(guī)套管偏梯形螺紋量規(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）41/2(114.3)8(3.175)1:16(3/4)41/2(114.7)5(5.08)1:16(3/4)5(127.0)8(3.175)1:16(3/4)5(127.4)5(5.08)1:16(3/4)51/2139.7)8(3.175)1:16(3/4)51/2(140.1)5(5.08)1:16(3/4)65/8(168.3)8(3.175)1:16(3/4)65/8(168.7)5(5.08)1:16(3/4)7(177.8)8(3.175)1:16(3/4)7(178.2)5(5.08)1:16(3/4)75/8(193.7)8(3.175)1:16(3/4)75/8(194.1)5(5.08)1:16(3/4)85/8(219.1)8(3.175)1:16(3/4)85/8(219.5)5(5.08)1:16(3/4)95/8(244.5)8(3.175)1:16(3/4)95/8(244.9)5(5.08)1:16(3/4)103/4(237.1)8(3.175)1:16(3/4)103/4(273.5)5(5.08)1:16(3/4)113/4(298.5)8(3.175)1:16(3/4)113/4(298.9)5(5.08)1:16(3/4)133/8(339.7)8(3.175)1:16(3/4)133/8(340.1)5(5.08)1:16(3/4)16(406.4)8(3.175)1:16(3/4)16(406.4)5(5.08)1:12(1)185/8(473.1)8(3.175)1:16(3/4)185/8(473.1)5(5.08)1:12(1)20(508.0)8(3.175)1:16(3/4)20(508.0)5(5.08)1:12(1)
