Kwicandelo lokukhusela ukugqwala kwemibhobho, ugqubuthelo lwe-polyethylene olunemigangatho emithathu (Ukwaleka kwe-3LPE) iye yaba lukhetho oluqhelekileyo olwamkelweyo kwihlabathi liphela ngenxa yokusebenza kwayo okuphezulu kokukhusela. Nangona kunjalo, ipharamitha edla ngokunganakwa kodwa ebalulekileyo bubukhulu bokugquma (Ubukhulu beCoating ye-3LPEAyisiyonto nje ebonisa imveliso, kodwa yeyona nto iphambili echaza ubomi benkonzo, ukhuseleko, kunye neenzuzo zoqoqosho zemibhobho kwiindawo ezinzima. Namhlanje, iCangzhou Spiral Steel Pipe Group, umenzi ophambili wemibhobho yentsimbi edibeneyo kunye neemveliso zokugquma imibhobho eTshayina, iza kugxila kwesi sihloko siphambili.
Imigangatho yoBungqingqwa: "Indlela yokuphila" yoKhuseleko lokuGqwala
Imigangatho yamazwe ngamazwe neyesizwe (efana ne-ISO 21809-1, GB/T 23257) inemigaqo ecacileyo nengqongqo malunga nobukhulu beengubo ze-3LPE. Le migangatho ichaza iimfuno zobugcisa zeengubo ze-polyethylene ezifakwe kwifektri ezineengqimba ezintathu ezisetyenziselwa ukukhusela imibhobho yentsimbi kunye nezixhobo. Isakhiwo sengubo sihlala siquka ungqimba lwe-epoxy powder underlayer, umaleko ophakathi we-polymer adhesive, kunye ne-polyethylene yangaphandle sheath, kwaye ubukhulu bengubo nganye kufuneka bulawulwe ngokuchanekileyo.
Kutheni i-3LPE Coating Thickness ibaluleke kangaka?
Ukhuseleko Loomatshini: Ubukhulu obaneleyo benza umqobo wokuqala obonakalayo ngokuchasene nemikrwelo, iimpembelelo, kunye nokuqhekeka kwamatye ngexesha lokuthuthwa, ukufakwa, kunye nokuzaliswa. Ubukhulu obungonelanga bukhokelela kumonakalo wengubo, okuvumela ukugqwala kuqale kwindawo.
Ukumelana nokuNgena kweeKhemikhali: Umaleko wangaphandle we-polyethylene otyebileyo uthintela ukungena kwexesha elide komswakama, ityuwa, iikhemikhali kunye neentsholongwane emhlabeni, nto leyo ebambezela ukufika kwezinto ezibolayo kumphezulu wombhobho wentsimbi.
Ukusebenza kokufakwa kwe-Insulation: Kwimibhobho efuna ukhuseleko lwe-cathodic, ubukhulu be-coating buchaphazela ngokuthe ngqo ukumelana kwayo nokufakwa kwe-insulation. Ubukhulu obufanayo nobuhambelanayo bubalulekile ekuqinisekiseni ukusebenza kakuhle noqoqosho kwenkqubo yokukhusela i-cathodic.
Ukuzibophelela Kwethu: Ulawulo Oluchanekileyo, Oluqinisekisiweyo Ngayinye I-Micrometer
I-Cangzhou Spiral Steel Pipe Group Co., Ltd. iyaqonda ngokunzulu ukuba ulawulo oluchanekileyo lobukhulu be-3LPE coating yeyona nto iphambili kumgangatho wemveliso. Ukusukela oko yasekwa ngo-1993, isebenzisa isiseko sethu semveliso sanamhlanje eCangzhou, eHebei, esigubungela iimitha zesikwere ezingama-350,000, kunye nezakhono zethu ezinamandla ezinomthamo wonyaka wemveliso weetoni ezingama-400,000 zeepayipi zentsimbi ezijikelezayo, siseke inkqubo yemveliso echanekileyo edibeneyo ukusuka ekuvelisweni kwepayipi yentsimbi ukuya kwi-anti-corrosion coating ephambili.
Kumgca wethu wokugquma, asiqinisekisi nje kuphela ukuba umaleko ngamnye we-3LPE Coating uhlangabezana nemigangatho ephezulu, kodwa sikwaqhuba nokubeka esweni ngokupheleleyo ubukhulu bokugquma kwepayipi nganye yentsimbi ngokubeka esweni okuphambili kwi-intanethi kunye novavanyo oluqinileyo olungaxhunyiwe kwi-intanethi (njengee-magnetic thickness gauges). Siqinisekisa ukuba ubukhulu bokugquma abuhlangabezani nemigangatho kuphela kodwa bufikelela kufana okuphezulu, sisusa amanqaku abuthathaka, ngaloo ndlela sizalisekisa ngokwenene ukuzibophelela kwethu ekuboneleleni ngezisombululo zepayipi zokulwa nokugqwala ezihlala ixesha elide kwiiprojekthi zamandla zehlabathi kunye neziseko zophuhliso.
Isiphelo
Ukukhetha imibhobho akupheleli nje ekukhetheni amandla entsimbi, kodwa kukwakho nokuqina "kwengubo yayo yangaphandle." Ubukhulu beCoating ye-3LPE buyindlela yokulinganisa yenqanaba lokukhusela "ingubo yangaphandle". I-Cangzhou Spiral Steel Pipe Group izimisele ukufezekisa le parameter ibalulekileyo, iqinisekisa ukuba yonke imitha yombhobho esiyivelisayo isebenza ngokukhuselekileyo nangokuzinzileyo kulo lonke ixesha layo elide, ibonelela ngesiqinisekiso sexabiso esihlala ixesha elide kutyalo-mali lwabathengi bethu.
Ngathi: I-Cangzhou Spiral Steel Pipe Group Co., Ltd. ngumvelisi ophambili weepayipi zentsimbi ezijikelezayo kunye neemveliso zokugquma iipayipi eTshayina. Le nkampani ineempahla ezipheleleyo ezingama-680 ezigidi zeeyuan, ixabiso lonyaka lemveliso eliyi-1.8 yeebhiliyoni zeeyuan, kunye nabasebenzi abangama-680. Ngeenkqubo zemveliso ezisemgangathweni ophezulu kunye neenkqubo zokulawula umgangatho, ikhonza icandelo lokuhambisa amandla kwihlabathi liphela kunye nolwakhiwo lweziseko zophuhliso.
