FAQ
Dab tsi yog qhov txawv ntawmAPI 5 CTthiab API 5L
Qhov sib txawv tseem ceeb ntawm API 5CT thiab API 5L yog nyob rau hauv lawv qhov chaw thov thiab cov yeeb nkab hom: API 5CT yog siv rau hauv cov kav dej thiab cov kav dej hauv cov roj av thiab yog nyob rau hauv cov kav dej downhole; thaum API 5L yog siv rau cov kav dej rau cov roj av thiab roj tsheb thauj mus los thiab yog nyob hauv cov kav dej ntev -.
Dab tsi yog hom xov sib txawv hauv API 5CT?
API 5CT tus qauv feem ntau suav nrog peb hom xov: luv round thread (STC), ntev round thread (LTC), thiab truncate thread (BTC), tag nrho cov uas yuav tsum tau ua raws li qhov yuav tsum tau ua thiab soj ntsuam ntawm API SPEC 5B.
