Xa kufikwa kuukwakha imibhobho, ukuqinisekisa ukuqina kwazo kunye nokuxhathisa ngokuchasene nomhlwa kubaluleke kakhulu.Imibhobho yentsimbi ye-LSAW yekhabhoni, ekwaziwa njengeLongitudinal Submerged ArcImibhobho yokuwelda, lukhetho oludumileyo ngenxa yamandla abo aphezulu kunye nokuthembeka. Ukomeleza ngakumbi ukuxhathisa umhlwa, le mibhobho ingagqunywa ngolwaleko oluthathu lwe-polyethylene anti-corrosion eyaziwa ngokuba yi-3PE. Kule bhlog, siza kuphonononga izibonelelo zokusebenzisaImibhobho yentsimbi yekhabhoni ye-LSAW 3PEkwaye kutheni belukhetho olubalaseleyo kumashishini ahlukeneyo.
I-3PE i-anti-corrosion coating iyisisombululo esithembekileyo esikhusela iipayipi zensimbi ze-LSAW zekhabhoni kwi-corrosion kunye nokwandisa ubomi babo. Ulwakhiwo lwe-3PE lunemigangatho emithathu, eqala nge-epoxy powder layer ebonelela ngokugqwesa ukunamathela kunye nokudibanisa kumphezulu wombhobho. Oku kulandelwa nguluhlu olunamathele, oluqinisa ngakumbi ukudibanisa phakathi kwe-epoxy kunye nenqanaba lokugqibela - i-polyethylene anti-corrosion. Uluhlu lwe-polyethylene lusebenza njengesithintelo, ukukhusela amanzi, iikhemikhali, kunye nezinye izinto ezitshabalalisayo ukuba zifike kwindawo yangaphakathi yombhobho. Ngaphezu koko, iyakwazi ukumelana namaqondo obushushu ukuya kuthi ga kwi-80°C, iyenze ifaneleke kuluhlu olubanzi lwezicelo.
Xa kuthelekiswa nengubo ye-2PE, ukongezwa kwe-epoxy powder layer kwi-3PE efakwe kwi-LSAW iipayipi zensimbi ze-carbon kwandisa ukusebenza kakuhle kwezinto ezichasene ne-corrosion. Olu luhlu olongezelelweyo luphakamisa ukuqina kunye nokuchasana nokugqoka kunye nokukrazula, ukuqinisekisa ukuba imibhobho inokumelana neemeko ezinzima zokusingqongileyo. Umbala oqhelekileyo weImibhobho egqunywe yi-3PEimnyama, kwaye ihambelana nemigangatho yamazwe ngamazwe efana ne-DIN30670, CAN/CSA Z245.21, kunye ne-ISO21809. Le migangatho engqongqo iqinisekisa ukuba imibhobho ihlangabezana nomgangatho ofunekayo kunye neendlela zokusebenza, okwenza kube ukhetho oluthembekileyo kumashishini ahlukeneyo.
Kwi-Botop Steel, sisebenza ngokukhethekileyo ekuboneleleni umgangatho ophezulu we-LSAW imibhobho yentsimbi ye-carbon kunye ne-3PE yokugquma i-anti-corrosion. Imibhobho yethu ifumaneka ngobukhulu ezahlukeneyo, amabakala, kunye neenkcukacha ukulungiselela iimfuno ezithile zabathengi bethu. Ngokuzibophelela kwethu ekugqweseni nasekuqwalaseleni iinkcukacha, siqinisekisa ukuba imibhobho yethu ihlangabezana neyona migangatho iphezulu yoshishino. Ukongeza, imibhobho yethu igqunywe nge-FBE anti-corrosion ukusuka ngaphakathi, iphucula ngakumbi ukuxhathisa ukubola. I-FBE yangaphakathi yokugquma ayinayo ityhefu kwaye inceda ukuthintela ukubola ngelixa iphucula izinga lokuhamba kwegesi kunye nolwelo ngaphakathi.umbhobho. Oku kwenza i-3PE yethu egqutywe i-LSAW ye-carbon steel pipes ibe yinto ethembekileyo kumashishini afana ne-oyile negesi, unikezelo lwamanzi kunye nokwakhiwa.
Ukuququmbela,Imibhobho yentsimbi yekhabhoni ye-LSAW 3PEzibonelela ngeenzuzo ezininzi, kubandakanya iipropathi eziphezulu zokuchasana nomhlwa, ukuqina okuphezulu, kunye nokumelana nokuguga nokukrazuka. Ukudityaniswa kwe-epoxy powder layer, i-adhesive layer, kunye ne-polyethylene anti-corrosion layer iqinisekisa ukuba imibhobho inokumelana neemeko ezinzima, ibenze ifaneleke kwizicelo ezahlukeneyo. Kwi-Botop Steel, siyazingca ngokunikelaimibhobho ekumgangatho ophezuluezihlangabezana nemigangatho yamazwe ngamazwe kwaye zigqithise oko kulindelwe ngabathengi. Tyala imali kwi-3PE egqunywe iipayipi ze-LSAW ze-carbon steel zesisombululo esithembekileyo nesihlala ixesha elide.
