Heavy Weight Drill Pipe
Integral heavy weight drill pombi inzvimbo yeshanduko pakati pekubooresa kora nepombi yekuchera.Izvo hazvigone chete kuderedza kushushikana-kuumbwa mukubatana kwechibooreso collar uye drill pombi, asiwo kuderedza kupfeka paOD.
Integral inorema huremu yekubooresa pombi inogadzirwa kubva kune imwe chidimbu cheAISI 4145H yakasimba bara, yakazara kupisa yakabatwa, zvese zvemuviri zvimiro zvinoenderana neAPI spec7 yazvino edition.
HWDP's wear resistance hard banding ndiyo yakajairwa pamaturusi majoini ekubatanidza uye pakati kugumbuka.Mhando dzemabhenji akaomarara anosanganisira Arnco 100XT uye100XT.Yese tambo ndeye phosphated, copperized kana kutonhora yakashanda.Zvese zvinongedzo zvine zvidziviriri zvesimbi zvakatsikirirwa.Yese madhidhiyo akagadzirwa neCNC lathes -Akapetwa kaviri-mapfudzi uye akakosha shinda.
