通径规DriftDiameterGauge通径规是检测套管、油管及其它管子内径的工具。它分为套管通径规和油管通径规。用它可以检查各种管子的内通径是否符合标准，检查其变形后所能通过的***大几何尺寸，是修井作业检测必不可少的工具。Overview:Driftdiametergaugesaresimpleandgeneraltooldesignedtomeasureinsidedriftsizeofcasing,tubing,drillpipeandotherpipes.Inordertoliveuptothestandardrequested,itusedtoinspecttheinsidedriftsizeofavarietyoftubings.Thebiggestsizewillbeknownthroughinspectingafterdeformation.Itistheessentialtoolinthecourseofworkover.Features:DriftDiameterGaugesaresimpleinstructure,safeandreliableinuse,high-efficiencyperformance,convenienceoperation.Specificati***andparametersofDriftDiameterGauges:技术参数套管系列用通径规(in)41/2551/253/465/87外径(mm)O.D.92-95102-107114-118119-128136-148146-158长度(mm)Length500500500500500500上部接头螺纹UperjointthreadNC2623/8TBGNC2627/8TBGNC3127/8TBGNC3127/8TBGNC3127/8TBGNC3831/2TBG下部接头螺纹LowerjointthreadNC2623/8TBGNC2627/8TBGNC3127/8TBGNC3127/8TBGNC3127/8TBGNC3831/2TBG油管规格(in)tubingspecification11/2221/2331/24外径(mm)O.D.384859738495长度(mm)length500500500500600600管子种类Pipetype规格(in)specificati***通棒尺寸overallsize长度(mm)length***小直径(mm)mindiameter套管casing≤85/891/8～133/8≥16150、305、305d-3.18d-3.97d-4.76油管tubing≤27/8≥31/21067、1067d-2.38d-3.18)
