Piga Kola
Chimba kola kama sehemu moja ya uzi wa kuchimba visima ni tubulari za viwandani zinazotumiwa kuchimba ardhini ili kutoa uzito kwa biti kwa kuchimba visima.Inatumika kwa kuunganishwa na bomba la kuchimba visima.Kuna aina mjanja na ond grooved hasa.Mchakato wetu wa utengenezaji umeidhinishwa kwa API maalum 7-1.Kola ya kuchimba visima imeundwa na AISI 4145 H au 4145 H Iliyorekebishwa alloy chuma.Bores ni trepanned kutoka upande mmoja na hakuna kutolingana.Kola zote za kuchimba visima hutibiwa kwa joto na ugumu ndani ya 285 hadi 341 BHN, ambazo zimehakikishiwa inchi moja chini ya uso wa bomba.
Kola zisizo za sumaku za kuchimba visima hutoa nguvu na ugumu huku zikizuia mwingiliano wa sumaku unaoweza kuharibu usahihi wa uchunguzi wa sumaku.Imetengenezwa kutoka kwa nyenzo maalum za chuma na upenyezaji mdogo, mali ya juu ya mitambo na upinzani wa juu kwa kupasuka kwa kutu.
Tunasambaza kola laini za kuchimba visima, kola za kuchimba visima ond na kola zisizo za sumaku za kuchimba visima;saizi zao ni kutoka inchi 3-1/8 hadi 11.Kando na kola za kuchimba visima katika jedwali lililo hapa chini, tunaweza kutoa kola nyingine za kuchimba visima kwa ombi la wateja.
