Pipa Bor Bobot abot
Pipa pengeboran bobot integral integral yaiku zona transisi antarane kerah pengeboran lan pipa pengeboran.Ora mung bisa nyuda formasi kaku ing sambungan krah pengeboran lan pipa pengeboran, nanging uga nyuda nyandhang ing OD.
Pipa pengeboran bobot integral integral digawe saka siji potongan bar padat AISI 4145H, diolah kanthi panas, kabeh sifat fisik cocog karo API spec7 edisi paling anyar.
Banding hard resistance HWDP minangka standar ing sambungan sambungan alat lan gangguan tengah.Jinis hard banding kalebu Arnco 100XT lan 100XT.Kabeh Utas wis phosphated, copperized utawa cold worked.Kabeh sambungan dilengkapi pelindung benang baja sing ditekan.Kabeh theads sing machined karo CNC lathes -Double-shoudered lan Utas khusus.
