Heavy Weight Drill Pipe
Ib qho hnyav hnyav laum yeeb nkab yog qhov chaw hloov pauv ntawm lub dab tshos laum thiab laum yeeb nkab.Nws tuaj yeem tsis tsuas yog txo cov kev ntxhov siab-tsim nyob rau hauv kev sib txuas ntawm laum dab tshos thiab laum yeeb nkab, tab sis kuj txo qhov hnav ntawm OD.
Ib qho hnyav hnyav laum yeeb nkab yog tsim los ntawm ib qho ntawm AISI 4145H khoom bar, siab kho cua sov, tag nrho cov khoom siv lub cev ua raws li API spec7 tsab ntawv kawg.
HWDP's hnav tsis kam hard banding yog tus qauv ntawm cov cuab yeej sib txuas thiab kev ntxhov siab hauv nruab nrab.Cov hom nyuaj banding muaj xws li Arnco 100XT thiab 100XT.Tag nrho cov xov yog phosphated, copperized los yog txias ua haujlwm.Tag nrho cov kev sib txuas yog nruab nrog nias steel xov protectors.Tag nrho cov theads yog machined nrog CNC lathes - Ob chav-shuddered thiab tshwj xeeb threads.
