Esimweni sezulu esishisayo nesishisayo ehlobo, kuba nemvula eningi, futhi isimo sezulu sishisa kakhulu futhi siswakeme ngemva kwemvula. Kulesi simo, ingaphezulu lemikhiqizo ethambekele ekulweni ne-alkali (evame ukubizwa ngokuthi ukugqwala okumhlophe). Uma izimpahla ezipuletiwe zingalandwa ngesikhathi, uma zingapakishwanga futhi zisetshenziswe ngesikhathi lapho zifika endaweni okuyiwa kuyo, ukwenzeka kwe-anti-alkali kuzokwenzeka kalula ukuze kuvinjelwe ukulahlekelwa okungenakuvinjelwa. Impilo yesevisi yeipayipi lensimbingokuvamile iyiminyaka eyi-8-12, nesilinganiso sempilo yesevisi yeminyaka eyi-10, futhi inganwetshwa endaweni eyomile.

Esimeni sezulu esinezimvula nesinenkungu, zama ukugcina noma ukumboza endlini ngangokunokwenzeka. Ngemva kokuma kwemvula nenkungu ihlakazekile, ishidi kufanele lisuswe ukuze lihlale lingena umoya futhi lomile; gwema ukuthintana ngqo nomhlabathi omanzi lapho unqwabelanisa.

Izindlela zokwelashwa kwemikhiqizo efakwe uthayela engena emanzini nokuswakama:

1. Uma ucezu lonke luvezwa emanzini, kufanele luhlakazwe ngokushesha futhi lubekwe endaweni engenawo umoya ukuze lome.

2. Uma kunokugqwala okumhlophe okuncane noma amachashaza ebusweni, kufanele kuhlakazwe futhi komiswe ilanga ngokushesha, futhi kusulwe ngesikhathi kuze kube yilapho ukugqwala okumhlophe kuphenduka impushana. Sebenzisa i-hot-dip galvanized self-spray paint ukuze umboze isifutho ngaphandle kokuphazamisa umphumela wokugqwala.

I-Seamless Mechanical Tubing: amashubhu asetshenziselwa izinhlelo zokusebenza zegeji yomshini nelula. I-Mechanical tube ikhiqizwa ukuze ihlangabezane nezidingo ezithile zokusetshenziswa kokuphela, imininingwane, ukubekezelela kanye namakhemikhali. Lokhu kuvumela ukufana kwempahla ethile kuyo yonke ishubhu uma kuqhathaniswa nepayipi elijwayelekile.
