Ubuchwepheshe bokuhlanza isihlabathi izindonga zangaphakathi zamapayipi basebenzisa umoya ocindezelwe noma imoto enamandla amakhulu ukushayela ama-blafu ama-bray ngejubane eliphakeme lokujikeleza. Lo mshini ubeka izinto ezihlukumezanayo ezifana ne-grit yensimbi, ukudubula insimbi, nesihlabathi se-garnet ngokumelene nepayipi lensimbi elingaphansi kwe-centrifugal Force. Le nqubo isusa ngempumelelo ukugqwala, oxides, kanye nokungcola ngenkathi kufeza ubulukhuni bomfaniswano ofunwayo endaweni yepayipi ngenxa yomthelela omkhulu kanye nokuphambana okulungiswe yi-abrasives. Ngemuva kokukhishwa kokugqwala kwe-sandblasting, akukho ukuthuthukiswa komthamo wepayipi wepayipi kodwa futhi kuthuthukiswa ekunamathisweni kwemishini phakathi kokulwa nokulwa nokuwohloka kwepayipi. Ngenxa yalokho, iSandblasting ibhekwa njengendlela efanelekile yokususwa kokugqwala ezinhlelweni zokulwa ne-corrosion.
UBlastany unikeza amamodeli amabili wesibhamu sangemuva sakwa-sandblasting yangaphakathi: JD SG4-1 ne-JD SG4-4, yakhelwe amapayipi okuhlanza ngama-dipeter ahlukahlukene. Imodeli ye-JD SG4-1 ithola ama-Pipe Diameters asukela kuma-300 kuye kwangama-900 mm futhi afaka ama-nozzle abunjiwe axhunyiwe ethangini le-sandblasting noma i-compressor yomoya yokuhlanza okusebenzayo kwangaphakathi. Ngaphansi kwengcindezi ephezulu, ukumangalela kukhishwe ngephethini fan, kusiza ukugqwala okusebenzayo nokususwa kokupenda. Ngakolunye uhlangothi, iJD SG4-4 ilungele amapayipi amancane anamawazi asuka ku-60 kuye kwangama-250 mm (anwetshwe afinyelela ku-300 mm lapho exhunywe ethangini lakwaSandBlasting noma i-air comprescessor, ngaleyo ndlela athuthukise ukusebenza kwawo kokuhlanza.
