Laum dab tshos
Laum dab tshos raws li ib feem ntawm ib txoj hlua laum yog cov tubular muaj ntau heev siv los laum rau hauv av los muab qhov hnyav ntawm me ntsis rau drilling.Nws yog siv los ua ke nrog cov yeeb nkab laum.Muaj ntau hom slick thiab kauv grooved feem ntau.Peb cov txheej txheem tsim khoom tau lees paub rau API spec 7-1.Lub caj dab laum yog ua los ntawm AISI 4145 H lossis 4145 H Hloov kho alloy hlau.Bores yog trepanned los ntawm ib qho kev taw qhia uas tsis muaj mismatch.Tag nrho cov laum dab tshos yog kub-kho nrog hardness nyob rau hauv 285 mus rau 341 BHN, uas yog guaranteed ib nti hauv qab ntawm cov yeeb nkab.
Tsis yog-magnetic laum dab tshos muab lub zog thiab tawv thaum tiv thaiv kev cuam tshuam sib nqus uas tuaj yeem cuam tshuam qhov tseeb ntawm kev tshawb fawb sib nqus.Nws yog tsim los ntawm cov khoom siv steel tshwj xeeb uas tsis tshua muaj permeability, muaj zog txhua yam thiab superior tiv thaiv corrosion.
Peb muab slick laum dab tshos, kauv laum dab tshos thiab tsis yog sib nqus laum dab tshos;lawv qhov ntau thiab tsawg yog los ntawm 3-1/8 mus rau 11 ntiv tes.Dhau li ntawm cov tho dab tshos nyob rau hauv cov lus hauv qab no, peb tuaj yeem muab lwm yam tho dab tshos ntawm cov neeg siv khoom thov.
