Imibhobhokwimveliso yemizi-mveliso kunye namacandelo asekuhlaleni anoluhlu olubanzi lwezicelo, zamanzi, i-oyile, igesi kunye nolunye ulwelo oluthuthwayo kusetyenziswa umbhobho unexabiso elifanelekileyo, elikhawulezayo neliphantsi leenzuzo ezininzi, ngakumbi kwinkqubo yothutho lomgama omde, onokubonisa iinzuzo kulo. kwixesha elide lodonga lwangaphakathi lombhobho lwenziwa kwi-deposition okanye ukungcola.Ukuba umbhobho uya kwenza isikali okanye ubumdaka babucala, uya kwenza udonga lwangaphakathi lwegrisi yombhobho okanye iwax eqokelelwe kumbhobho werhasi yoshishino iya kwenza icoke coke kunye nobunye ubumdaka.Ukungcola okufakwe kulwelo lwemibhobho kwandisa kakhulu ukuxhathisa ngexesha lothutho kungekuphela nje ukusebenza kakuhle kokuhanjiswa kunye nokusetyenziswa kwamandla afunekayo ekuthutheni ulwelo nako kunyuke kakhulu.Ukungcola kuya kubangela ukonakala kwimathiriyeli yombhobho kwaye kubangele umonakalo omkhulu ekugqabhukeni kombhobho, ilahleko yokuvuza kolwelo olusasaza, kwaye lubangele nokuvalwa.Ukonakala kwemibhobho kaninzi kubangelwa kuthutho lwemibhobho engcolisekileyo Ngokoqoqosho, owona mngcipheko mkhulu wokhuseleko.Ngokunyuka kombhobho kunye noxinzelelo lwemibhobho eyandisiweyo yobudala inyukile, ukubaleka, ukuthontsiza, ukukalwa, umhlwa, ukuplaga kunye nogqabhuko lombhobho ophumayo, oku kusilela kuya kubonakala nje imveliso eqhelekileyo kwaye ubomi buya kuchaphazeleka kakubi kubomi babantu kunye nepropathi ebangele umonakalo ongalungisekiyo, ke ngoko. isidingo sokucocwa rhoqo kombhobho.Imibhobho ecocekileyo ngokweemeko ezithile zokulinganisa ezahlukeneyo usebenzisa iindlela ezahlukeneyo, njengokusebenzisa iasidi, ialkali okanye isisombululo samanzi samanzi samachiza avaliweyo okucoca umbhobho weloop, ungasebenzisa i-ultrasound, ijethi yamanzi, okanye ezinye iindlela zomzimba zokungcolisa kwaye isusiwe eludongeni kodwa ikhaphukhaphu kumanqanaba okuqala ombhobho wokwamkelwa kokwamkelwa kweehagu inokuba yindlela elula, enexabiso eliphantsi kodwa enesiphumo esihle.Ukucoca iihagu kushishino, okwakwaziwa njengokucoca iihagu.

I-pigging yinto ekhethekileyo ye-polyurethane emise okwembumbulu yezixhobo, ukuxhathisa ukucutheka, amandla aphezulu.Iteknoloji yokucoca i-pigging ukususa isikali sombhobho, intlenga okanye umzimba wangaphandle ngenjongo yeteknoloji.Umgaqo wayo wokusebenza ufakwa kwiziqhubi zeHagu emva kokuqalisa indlela eya phambili yezosasazo kumohluko woxinzelelo lweHagu, ukwakheka kokutyhalela phambili, iHagu iqhubela phambili ecaleni kombhobho, ngexesha lokusebenza, iHagu ikhubazeke kancinane.Ihagu ngokwayo okanye iziqhotyoshelo zayo kwizithethe ezingcolileyo zisoloko zinxibelelana nodonga, zikhama ngokuchasene nokungcolisa, i-scrapers, ukhukuliseko, ukungcangcazela okwaphukileyo, ukususa ubume bombhobho, intlenga kunye nezinto zangaphandle.Kwangaxeshanye, eliphakathi eludongeni ityhubhu ngokusebenzisa wathi ukupheka Ihagu gap wakha annulus yenziwa xa isantya esiphezulu jet, indima yayo kummandla wangaphambili kwakhiwa njenge vacuum, ilungele ukusebenza Ihagu, kunye ukukhuhla The Impembelelo ye-slag engcolileyo, i-tube yokukhupha kunye nexesha elifanelekileyo, ikhusela ngokufanelekileyo ukuqokelelwa kokungcola kwe-residu kwi-tube ukuphepha i-clogging phenomenon.

I-Pigging ibonakaliswe ngenxa yokuba yenziwe nge-polyurethane foam kunye nokuguquguquka okulungileyo, ukwenzela ukuba, kumgca we-conduit we-elbow, izixhobo ze-tee kunye necandelo lombhobho omncinci unokugoba ngokulula kwaye unokumelana nokunxiba kakuhle, kunokwenzeka ukuhamba imigama emide umbhobho.Ekucoceni ukuya kwiikhilomitha eziliqela kunye nokumila kwemibhobho yokucoca ngoomatshini okanye ukucoca ijethi kunobunzima bokusebenzisa ukucoca iihagu kunokuba bhetele ukugqiba imisebenzi yokucoca.
