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, inokumelana 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 kwerhasi 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.
