Ipayipi Lokubhoboza Kahle

Incazelo emfushane:

Ipayipi lokubhoboza, uhlobo olufushanisiwe lwepayipi lokubhoboza phansi, liwuhlobo lwenduku yokubhoboza eyisicaba yangaphandle.Isetshenziswa kakhulu ekubhobolweni kwe-rotary percussive equkethe amagesi noketshezi.Izingxenye zayo eziyinhloko zihlanganisa umzimba wepayipi (induku) kanye nelunga.

Umlayezo I-imeyili

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Amapayipi okugaya asetshenziswa kakhulu ezimayini, ukuhlola umhlaba kanye nazo zonke izinhlobo zokumba(amanzi, uwoyela, igesi, njll) amaphrojekthi.Njengomkhiqizi ohamba phambili wamapayipi okubhola, senza zonke izinhlobo zezindinganiso kanye namapayipi okubhola angajwayelekile kumakhasimende ethu.Amapayipi ethu okubhola ahlanganisa ipayipi lokubhoboza insimbi, ipayipi lokubhola lezimayini, ipayipi lokubhoboza amanzi, ipayipi lokubhoboza uwoyela, ipayipi lokubhoboza i-API, i-DTH drill rod, i-wireline drill rod, njll.

Izici ezibalulekile zeshubhu ye-DTH yekhwalithi ephezulu ukuqina, ukunemba nokuphathwa.

I-Drill Pipe :

1.Umzimba wepayipi: ipayipi elibandayo elidonsayo elingenamthungo.ngakho-ke ipayipi inosayizi onembile, i-centralizer enhle.
2.Impahla yomzimba wepayipi iyibanga elifanayo nele-Sandvik.
3.Isixhumi sochungechunge :Ukwelashwa kokushisa neNitrojeni , ngakho ipayipi lihlala isikhathi eside futhi kulula ukulilayisha nokulikhipha .
4.Friction welding.

Ipayipi lokubhoboza elijwayelekile le-DTH:

Ububanzi: 76mm, 89mm, 102mm, 114mm, 127mm, 140mm;

Ubude: 1000mm, 1500mm, 2000mm, 3000mm, 5000mm, 6000mm;

Uchungechunge: 2 3/8” API REG, 2 7/8” API REG, 3 1/2” API REG, 4 1/2” API REG,

2 3/8 API IF, 3 1/2 API IF
