Iyintoni indlela yokususa i-rust ye-welded steel pipe kunye nokubaluleka kwayo

I-anti-corrosion yemibhobho yensimbi engcwatywe yinkqubo ephambili yokuqinisekisa nokwandisa ubomi bayo benkonzo. Ukuqinisekisa ukuba i-anti-corrosion layer insulation idityaniswe ngokuqinileyo kunye nodonga lombhobho, ukukhutshwa kombhobho kumbhobho kubaluleke kakhulu. Ngokuqhelekileyo, umhlwa phezu kombhobho wentsimbi unokwahlulwa ube ngumhlwa odadayo, umhlwa ophakathi, kunye nomhlwa onzima ngokwexesha lomzi-mveliso, ukugcinwa kunye neemeko zokuthutha, kunye neqondo lokufuma.

Umhlwa odadayo: Ngokuqhelekileyo, xa isango lomzi-mveliso lifutshane kwaye ligcinwe ngaphandle kwendawo evulekileyo, kukho umlinganiselo omncinci we-crust obhityileyo kumphezulu wombhobho. Ukukhanya kwesinyithi kunokuvezwa ngemisebenzi yezandla efana nebrashi yocingo, i-sandpaper, kunye nomsonto womqhaphu.

I-rust ephakathi kunye ne-rust enzima: Xa umhla wokuhambisa ude kwaye ugcinwe emoyeni ovulekileyo okanye uthuthwa ngokuphindaphindiweyo kwaye ukuthutha ixesha elide, umphezulu wombhobho uya kubonakala u-oxidized kunye ne-rust, kwaye i-rust spots iya kuba nzima, kwaye Isikali se-oxide siya kuwa kwiimeko ezinzima.

Imibhobho edleke kakhulu ayifanelekanga kwiinkqubo zokuhanjiswa kwamanzi angaphantsi kwamanzi. Kwimibhobho ye-rust ephakathi kunye neebhetshi ezinkulu, ukuchithwa komatshini kunokwenziwa kusetyenziswa ukususwa kwe-rust okanye iindlela ze-sandblasting zomatshini, ezinokuphucula ukusebenza kakuhle kunye nokunciphisa ukungcoliseka kwabantu kunye nomoya.

Umgangatho ophezulu wokuchasana nokubola uyafuneka okanye iindonga zangaphakathi nangaphandle zombhobho ziye zahlwa, iindlela zokususa i-chemical rust zingasetyenziselwa ukususa ngokufanelekileyo i-oxides kwindawo yangaphakathi nangaphandle yombhobho. Kungakhathaliseki ukuba yeyiphi indlela esetyenziselwa ukususa i-rust, i-anti-corrosion layer kufuneka iphathwe ngokukhawuleza emva kokususwa kwe-rust ukuphepha i-oxidation kunye ne-corrosion emoyeni kwakhona.
