API coupling yog dab tsi?
API Coupling yog hais txog qhovsteel couplings uas siv rau hauv kev sib txuas cov yeeb nkab thiab tubing. Kuj paub los ntawm OCTG coupling, feem ntau yog tsim los ntawm seamless hom, cov khoom qib tib yam nrog cov yeeb nkab lub cev (API 5CT K55 / J55, N80, L80, P110 thiab lwm yam), PSL tib yam los yog muab qib siab dua li thov.
Casing coupling yog dab tsi?
Qhov ntev ntawm cov yeeb nkab siv los txuas ob lub pob qij txha ntawm lub casing. Lub casing coupling muaj cov xov sab hauv (poj niam threadform) machined kom phim cov xov sab nraud (txiv neej threadform) ntawm cov pob qij txha ntev ntawm casing. Ob lub pob qij txha ntawm lub casing yog threaded rau hauv opposite xaus ntawm casing coupling.
API casing yog dab tsi?
Cov kav dej yog siv rau cov roj thiab roj qhov dej drilling thiab roj thiab roj tsheb thauj mus los. Nws muaj xws li ib tug roj drilling yeeb nkab, roj casing, thiab roj extraction yeeb nkab. Roj laum yeeb nkab feem ntau yog siv los txuas cov laum dab tshos thiab laum cov khoom thiab xa lub zog drilling.
API kam rau ua casing yog dab tsi?
Tolerance rau casing thiab tubing phab ntsa thickness yog-12.5%.
