Ipayipi lokubhoboza i-HDD likhethwa yi-drill pipe material, umumo we-cross-section, usayizi wejometri, nobude bokucaciswa.Ikhethwa ngokuhambisana nobukhulu bomsebenzi womthelela we-rock drill, izinga lokuthamba nobulukhuni bedwala, ububanzi bekhanda lokubhoboza, ukujula kwembobo yedwala, izidingo zokuxhunywa kwe-rock drill esetshenziswa i-drill tail shank, kanye nendlela yokudla ye-rock drill.
Ngokujwayelekile ngaphansi kwesisekelo sokuhlangabezana nezidingo zokumba, amapayipi okubhoboza anesiphambano esimaphakathi, isisindo esilula, ubude obufushane, ukuqina okuhle nokuphila isikhathi eside kufanele kukhethwe ngangokunokwenzeka.Ngokwemba amatshe okubanjwa ngesandla, izinduku zokubhola i-H22 kanye ne-H25 uxhumo lwe-taper kanye ne-cross-sections ene-hexagonal ngokuvamile kukhethwa.Usayizi womsila wokubhoboza ngu-108mm x H22 futhi impahla ingu-55SiMnMo, 95CrMo, njll. Ukuze kumbiwe umzila oyisicaba kanye nokubhola amatshe, i-H25, H28, H32, ne-H35 exhunywe ingxenye eyi-hexagonal enemicu ye-cross-section enobubanzi obufanayo, ukunciphisa ububanzi. kanye nezinduku zokubhola ezishintsha ngokushesha zivame ukukhethwa. Ukuze kukhiqizwe ukumba amatshe (izimayini ezingaphansi komhlaba nezivulekile), i-D35, D38, D45, D51, D60, D65, D76, kanye ne-D87 eyindilinga eyindilinga, ukuxhumana okunentambo ububanzi obufanayo, ububanzi obuncishisiwe, nezinduku zokubhola ezishintsha ngokushesha namapayipi okubhoboza ngokuvamile akhethwa.
Umgomo wokukhetha wobude bokucaciswa uthi: kunqunywa ngokwezidingo zokujula kokumba, ngokuvamile ku-0.3—7.3 ngaphakathi kobubanzi be-mm.
