Drill Steel
Iyo pombi yekuboorera, iyo yakapfupikiswa yepasi pegomba pombi yekuboorera, imhando yekunze kwetsvimbo yekuboorera.Inonyanya kushandiswa muku rotary percussive drilling ine magasi uye zvinwiwa.Zvikamu zvaro zvikuru zvinosanganisira pombi (tsvimbo) muviri uye majoini.
Yedu pasi pegomba drill pombi inogadzirwa zvichienderana neiyo API zviyero.Uye maererano nezvinodiwa chaizvo, isu tinopawo rudzi urwu rwepombi yekuchera mune zvakasiyana Chinese neAmerica zvakatemwa.
Kana zviri zvakanakira kwayo, ine zvimiro zvekusimba kwakakura, yakanaka yekuisa chisimbiso, yakadzika yekunze chimiro, uye yakaderera torque uye kuramba kana ichitenderera.
Nezvekurongedzerwa, svinga remapombi ekuboorera richaiswa neseti imwe yefuremu yesimbi, uye sumbu rinenge riine mapaipi 9 kusvika ku40 ekuboorera.
Raw Material: Kupisa kwakatenderedzwa seamless pombi, kubva BAO STEEL / TPCO / BAO GANG uye zvichingodaro, Zvakanyanya zvinoenderana neakakodzera zviyero zvekuongorora, kuburikidza nekugadzira chirimwa, kugadzirisa chirimwa chekuongorora kaviri, kuve nechokwadi chemhando yezvigadzirwa.
