Tekinoroji yekuchenesa madziro emukati memapaipi inoshandisa mhepo yakamanikidzwa kana mota ine simba guru kufambisa maburi ekupfapfaidza nekumhanya kwakanyanya. Iyi nzira inofambisa zvinhu zvinogumbura zvakaita sesimbi, simbi, uye jecha regarnet pamusoro pepombi yesimbi pasi pesimba re centrifugal. Maitiro aya anobvisa ngura, ma oxide, uye tsvina uku achiwana roughness yakafanana pamusoro pepombi nekuda kwekukanganiswa kwakanyanya uye kukweshana kunokonzerwa ne abrasives. Mushure mekubvisa ngura kubva mu sandblasting, hapana kungowedzera kugona kwe adsorption kwepombi asiwo kuvandudzwa kwekunamatira kwe mechanical pakati pe anti-corrosion coating nepaipi. Nekuda kweizvozvo, sandblasting inoonekwa senzira yakanakisisa yekubvisa ngura mumashandisirwo e anti-corrosion paipi.
Blastany ine mhando mbiri dzepfuti dzemukati dzejecha dzinoputika: JD SG4-1 naJD SG4-4, dzakagadzirirwa kuchenesa mapaipi ane dhayamita dzakasiyana. Modhi yeJD SG4-1 inokwana dhayamita dzemapaipi dzinotangira pa300 kusvika 900 mm uye ine nozzle yakaita seY inogona kubatanidzwa netangi rekuputika jecha kana compressor yemhepo kuti ichenese mukati zvakanaka. Kana paine kumanikidzwa kwakanyanya, zvinobvisa mabrasives zvinoburitswa mufanidzo yefeni, zvichiita kuti ngura ibudirire uye pendi ibviswe zvakanaka. Kusiyana neizvi, JD SG4-4 yakakodzera mapaipi madiki ane dhayamita kubva pa60 kusvika 250 mm (inotambanudzwa kusvika pa300 mm) uye inobvumira kupfapfaidza nemadhigirii 360 kana yakabatana netangi rekuputika jecha kana compressor yemhepo, nokudaro zvichiwedzera kushanda kwayo pakuchenesa.
