PDC HDD (Horizontal Directional Drilling) Drill Bits
Mafotokozedwe Akatundu
Ma bits osawonongeka a HDD awa ndi zoyikapo zimatha kupirira mawanga onse ovuta ndi zigamba zolimba zomwe kubowola kumatha kukuponyerani. Kaya mukubowola miyala kapena dothi, Grand Construction ili ndi njira yoyenera yobowolera kapena kuyika pulojekiti yanu.
Zobowola za PDC HDD zimatha kubowola zapakati mpaka zapakati zolimba. Ndikoyenera kubowola shale, mudstone, Cemented Sandstone ndi carbonate thanthwe ndi mphamvu yapakatikati. Tili ndi zida zambiri zobowola za HDD, monga ma milled-tooth pilot bits zofewa komanso zomasuka. Ndi chitetezo chokhazikika cha lining, chitsulo cholimba pa bevel ndi kutulutsa kwamkati kwa cone, zowongolera zimatha kupirira zovuta zoboola zomwe zimakumana ndi HDD.
Chimodzi mwazabwino zobowola HDD ndi kuthekera kwawo kowongolera, komwe kumawalola kuti azitha kuyang'ana molunjika ngakhale zovuta kwambiri pakubowola. Kaya mukubowola mumsewu wa mzinda kapena pansi pa mitsinje, mutha kudalira ma drill athu a HDD kuti azipereka ntchito zolondola komanso zodalirika nthawi iliyonse.
Kuphatikiza pa luso lawo lodula ndi chiwongolero, ma Horizontal Directional Drilling Bits adapangidwanso kuti achepetse kugwedezeka komanso kuchepetsa kung'ambika pazida zanu zobowola, zomwe zimathandizira kukulitsa moyo wa zida zanu ndikuchepetsa nthawi yochepera pamapulojekiti anu obowola.
Mosiyana ndi ma bits wamba omwe amatsogozedwa ndi PDC, ma bits athu a Grand Construction amapereka maubwino angapo, kuphatikiza:
Mapangidwe owonjezera kuti abowole mwachangu pamapangidwe amiyala.
Ma stabilizer omangidwira kuti mulingo wobowola ukhale wokhazikika.
Zida zambiri za PDC zokhala ndi moyo wautali kuposa zida zobowola za PDC.
Ma bits athu otsogola a HDD akupezeka mu makulidwe a 5-1/2" ndi 6-1/2". Chigawo chilichonse chimakhala ndi mapangidwe athu olimba komanso olemekezeka kwambiri a 5-blade, kuphatikiza chida cha 13mm PDC, chaukadaulo, cholondola komanso chaluso pantchito iliyonse yoboola miyala.
