Imibhobho edityanisiweyo yeSpiral (SSAW) yeeprojekthi zogcino lwamanzi idla ngokuba yimibhobho yentsimbi ejijekileyo enedayamitha enkulu ngokwentelekiso, kuba amanzi adlulayo ngexesha leyunithi nganye makhulu, nto leyo enokuphucula kakhulu ukusebenza kakuhle. Ekubeni udonga lwangaphakathi lombhobho wensimbi ejikelezayo luhlala luhlanjwa ngamanzi, udonga lwangaphakathi aluphathwanga ngonyango lokulwa nokubola, kodwa ingaphandle ngokubanzi ikwimo ephezulu, ngoko ke i-anti-corrosion kufuneka yenziwe ukujongana nayo. ukhukuliseko lwemvula kunye nokuba sesichengeni selanga, ngoko ke iimfuno zokwaleka okuchasene nokuhlwa ziphezulu.

Ngaphambi kwe-anticorrosion ye-spiral steel pipes kwiiprojekthi zokugcinwa kwamanzi, umphezulu wemibhobho yentsimbi kufuneka uqhutyelwe isanti, kwaye ibakala kufuneka lifikelele kwi-st2.5. Emva kokuqhuma kwesanti, sebenzisa i-anti-corrosion primer ngokukhawuleza. I-anti-corrosion primer ngokuqhelekileyo yipeyinti ye-epoxy zinc ecebileyo kunye nomxholo we-zinc we-70% okanye ngaphezulu, umbindi yipeyinti ye-epoxy mica, kwaye i-outmost layer i-anti-oxidation kunye ne-corrosion. Ipeyinti yePolyurethane.

Ngaphambi kokushiya i-factory, umbhobho wensimbi ojikelezayo kufuneka uvavanywe kwiipropati ze-mechanical, flattening kunye ne-flaring, kwaye kufuneka ihlangabezane neemfuno zomgangatho. Imibhobho yentsimbi edityanisiweyo ene-Spiral inokuguquguquka okukhulu kuluhlu lwedayamitha kunye nobungqingqwa bodonga, ngakumbi kwimveliso yemibhobho enodonga olungqingqwa yodidi oluphezulu, ingakumbi imibhobho etyebileyo enodonga oluphakathi. Kukho iimfuno ezingaphezulu ngokubhekiselele kwiinkcukacha zemibhobho yentsimbi ye-spiral. Idayamitha kunye nobukhulu boluhlu lwenkcazo yombhobho wentsimbi ejikelezayo kufuneka ilawulwe ngokuguquguqukayo.

Ukuphunyezwa kwe-anti-corrosion engineering kufuneka ihlangabezane nezi meko zilandelayo ngaphambi kokuba iphunyezwe:

Okokuqala, isicwangciso kunye namanye amaxwebhu obugcisa agqityiweyo, kwaye imidwebo yokwakha kufuneka ihlaziywe ngokubambisana. Okwesibini, ukubhengezwa kobugcisa besicwangciso sokwakha kugqityiwe, kwaye ukufundiswa kweteknoloji yokhuseleko kunye noqeqesho lobugcisa oluyimfuneko luyaphunyezwa. Okwesithathu, zonke izixhobo, izixhobo zombhobho kunye nezixhobo kufuneka zibe nesatifikethi sefektri, okanye isatifikethi se-akhawunti esihambelanayo. Okwesine, izixhobo, oomatshini, izixhobo zokwakha kunye nesiza zicokisekile. Okwesihlanu, kufuneka kubekho izixhobo ezithembekileyo zokukhusela ezikhuselekileyo nezithembekileyo, kwaye amanzi okwakha, umbane negesi kufuneka zikwazi ukuhlangabezana neemfuno eziqhubekayo zokwakha.
