Igama eliqhelekileyo leenkqubo zokutofa ezisebenzisa izisombululo zeekhemikhali ezikhethekileyo zokuphucula ukubuyiswa kwe-oyile, ukususa umonakalo owenziweyo, ukucoceka kwe-perforations evaliweyo okanye iileya zokwakheka, ukunciphisa okanye ukuthintela ukubola, ukuphucula i-oyile ekrwada, okanye ukulungisa imiba yokuqinisekisa ukuhamba kweoli ekrwada.Isitofu sinokuqhutywa ngokuqhubekayo, kwiibhetshi, kwimingxuma yokutofa, okanye ngamanye amaxesha kwimithombo yemveliso.
Ukuqinisekisa ukuhamba kolwelo oluveliswayo kunye nokukhusela isiseko sakho semveliso kwiplagi kunye ne-corrosion, udinga imigca yesitofu ethembekileyo yonyango lwakho lwemveliso yemichiza.Imigca yokutofa ngemichiza evela kwi-Meilong Tube inceda ekuphuculeni ukusebenza kakuhle kwezixhobo zakho zemveliso kunye nemigca, zombini kumngxuma osezantsi nangaphezulu.
