Different casing pipes and tubing pipes need different types of couplings to connect. So couplings for casing pipes have three thread types, and they are couplings for STC (short round thread casing), LTC (long round thread casing) and BTC (buttress thread casing) respectively. So are the couplings for tubing pipes, they are couplings for EUE tubing pipes and NU tubing pipes.SpecificationitemvalueSection ShapeRound 48.26mm - 406.4mmSurface TreatmentOtherOiled or Non-oiledSlightly OiledPlace of OriginChina Inner MongoliaAlloy Or NotNon-AlloyStandardAPI 5CTGradeJ55, K55, N80, L80, P110, Q125Delivery Time22-30 daysTolerance±5%, ±1%Invoicingby actual weightBrand NameBAOTOU STEELApplicationcasing and tubing couplingSpecial PipeAPI PipeThickness3.18 - 22.22 mmCertificateAPI, GS, ISO9001Processing ServiceCuttingProduct nameAPI 5CT Pipe CouplingOEMacceptVisit factotywelcomedSection shaperoundBrand NameBaotou SteelMaterialJ55 K55 N80 L80-1 C90 R95 P110 BT110T Q125Payment termsT/T,L/CTypeSeamless Steel PipeCertifications
