    Amandla angenakuthelekiswa nawo kunye nokuqina:

    I-ASTM A252I-Spil Deeld Pipe Pipeyenziwa ngentsimbi ephakathi ehlanganisiweyo edibana ne-A252 imigangatho. Umgangatho oqinisekileyo woqhankqalaza kunye nokuqina kwemibhobho, ibenza bafaneleke izicelo ezahlukeneyo kubandakanya ukuhanjiswa kweoyile kunye negesi kunye neziseko zamanzi. I-Willing Wiels yonyusa amandla kunye nokuxhathisa kwemibhobho kumakhosi angaphandle, ukuqinisekisa ukuba banokumelana neemeko zoxinzelelo oluphezulu kunye neemeko zemozulu ezinzima.

    Ukusebenza kakuhle kunye nokusebenza ngempumelelo:

    Enye yezona zibonelelo ziphambili ze-ASTM A252 i-spils yentsimbi ye-Welfmed ye-Wiel ye-Weel yeSpleed ngumbhobho ongaphezulu wokufaka kunye nokusetyenziswa. Uyilo lwayo lweSpiral kulula ukuthutha kwaye lubaphathe ngenxa yobunzima bayo obulula xa kuthelekiswa neminye imizobo. Ukongeza, ukuguquguquka kwale mibhobho baququzelela ukugoba, ukunciphisa iimfuno zezinto ezifanelekileyo kunye namalungu. Ayisiyo kuphela le xesha, ikwanciphisa kakhulu iindleko zokufakelwa, ukwenza olu hlobo lwe-succtopy isisombululo esinexabiso leeprojekthi ezahlukeneyo.

    I-Piperal Pipe Deling Count

    Ukunganyangeki kwe-corosion ephuculweyo:

    I-South yeyona ngxaki iphambili kwiinkqubo zokwenza imibhobho, ngakumbi kumashishini athwalisa iikhemikhali kunye nezinto ezibonisa ukuba zikhohlakele. I-ASTM A252 iqinisekisa ukuba imibhobho yentsimbi ye-Welfd ye-Welfd ibonakalisa ukumelana nokunganyangeki. Le mibhobho ineengubo ezikhuselayo ezinje nge-Epoxy okanye i-zinc enjengomqobo kwiarhente zoncedo, yandisa ubomi babo ngenkonzo kunye nokunciphisa iindleko zokugcina. Eli nqaku liyingenelo ikakhulu kwizicelo eziphantsi komhlaba okanye elunxwemeni apho imibhobho ityhilwe kwiimeko ezikhoyo zokusingqongileyo.

    Umthamo omkhulu wokuthwala:

    Olunye uphawu olubalulekileyo lwe-ASTM A252 I-Pipel Pipe yeSpleed Weld ingumbhobho omkhulu ungumthamo wayo oboleka umthwalo. Itekhnoloji ye-Willing ye-Pililing esetyenziswa kwinkqubo yokuphucula iphucula amandla ombhobho kunye nokukwazi ukumelana nemithwalo enzima. Nokuba isetyenziswa kulwakhiwo lwebhulorho, iziseko zesakhiwo okanye imibhobho engaphantsi komhlaba, le mibhobho ibonelela ngengqibelelo ebalaseleyo, ukunciphisa umngcipheko wokungaphumeleli kunye nokuqinisekisa ukhuseleko lwexesha elide lweeprojekthi ezahlukeneyo.

    Ukuzinza kwendalo:

    Kwixesha apho ukukhuselwa kokusingqongileyo kuyinkxalabo yehlabathi, ukukhetha izixhobo zokwakha ezifanelekileyo kubalulekile. I-Spilly ye-Welfmed Pipe i-A252 ihambelana neendlela zokwakha ezizinzileyo ngenxa yokuqina kunye nokuphinda zisebenzise kwakhona. Imibhobho yobomi benkonzo ende kwaye inokuphinda iphinde isebenze ngokulula ekupheleni kobomi babo, ukunciphisa isidingo sento entsha yokukhupha ngelixa kuncitshiswa inkunkuma kunye nokukhutshwa kwekhabhoni.

    Ukuququmbela:

    I-SPIRAL ye-WelDed Pipe Esstm A252 ihambe ishishini lomhlaba kunye namandla aphezulu, ukuqina kunye nokusebenza ngempumelelo. Le mibhobho idibana okanye idlula kwimigangatho yemveliso, ibenza ukuba ukhetho lokuqala kumashishini amaninzi. Ukuxhaphaza kwakhe umthwalo kunye nokuxhathisa ngokunyanzelwa komthwalo kunye nokuxhaphaza i-Porrosion Qinisekisa ukukhula okuzinzileyo kweeprojekthi zeziseko zophuhliso kunye negalelo kukuqhubela phambili kweshishini lehlabathi. Ngokusebenzisa le mibhobho, iiprojekthi zokwakha zinokuphucula ukusebenza kokufaneleka, ukunciphisa iindleko kunye nokuqinisekisa ukuthembeka kwexesha elide ngelixa unamathela kwiimeko zokusingqongileyo.
