    Ipayipi lensimbi eluhlaza okwesibhakabhaka lamandla angenakuqhathaniswa nokusebenza kahle kwe-ASTM A252

    Kuvunguza ipayipi lensimbi eline-welded for amandla angenakuqhathaniswa kanye nokusebenza kahle kwe-ASTM A252 isithombe
    • Ipayipi lensimbi eluhlaza okwesibhakabhaka lamandla angenakuqhathaniswa nokusebenza kahle kwe-ASTM A252

    Incazelo emfushane:

    Lokhu kucaciswa ukuhlinzeka ngezinga lezokukhiqiza ngohlelo lwepayipi ukuhambisa amanzi, igesi kanye namafutha asezimbonini zegesi zemvelo.

    Kunamazinga amabili okucaciswa komkhiqizo, i-PSL 1 nePSL 2, i-PSL 2, inezidingo eziphoqelekile zekhabhoni elingana, ukuqina kwe-notch, amandla aphezulu wesivuno namandla aphezulu.

    Yethula:

    Uma kukhulunywa ngokuthuthukiswa kwengqalasizinda, amasistimu wepayipi ayingxenye ebalulekile edlala indima ebalulekile ezimbonini ezahlukahlukene. Kusetshenziswa izinto ezifanele namasu okulokwakhiwa kwamapayipi kuqinisekisa ukuqina, amandla kanye nokwethenjwa, futhiKuna selded welded steel pipe astm A252ingaphambili yalokhu kuthuthuka kwezobuchwepheshe. Kule bhulogi, sizobhekisisa izimfanelo ezinhle nezinzuzo zalezi zipay eziphawuleka eziye zaba yinto ebabazekayo emisebenzini yanamuhla yokwakha.

    Incazelo Yomkhiqizo1

    Amandla angenakuqhathaniswa nokuqina:

    I-ASTM A252Kuvunguza insimbi ye-welded yensimbiyenziwe ngensimbi esezingeni eliphakeme ehlangabezana namazinga we-ASTM A252. I-Standard iqinisekisa amandla aphezulu nokuqina kwamapayipi, okwenza balungele izinhlelo ezahlukahlukene zokusebenzisa kufaka phakathi ukuhanjiswa kwamafutha kanye negesi kanye nengqalasizinda yamanzi. I-Welds ePhilayo yandisa amandla kanye nokumelana kwamapayipi kumabutho angaphandle, ukuqinisekisa ukuthi bangamelana nezimo eziphakeme zengcindezi kanye nezimo zezulu ezinzima.

    Ukusebenza kahle okuhle nokusebenza kwezindleko:

    Enye yezinzuzo eziyinhloko ze-ASTM A252 Spiral Welded Pipe ingukusebenza kwayo okuphezulu ekufakweni nasekusetshenzisweni. Idizayini yayo eyi-Spiral kulula ukuhambisa futhi ibambe ngenxa yesisindo sayo esilula ngokuqhathaniswa nezinye izinto zepayipi. Ngokwengeziwe, ukuguquguquka kwalawa mapayipi kusiza ukugoba, ukunciphisa izidingo zokufakelwa kanye namalunga. Akugcini nje kuphela ukuthi le nto yonga isikhathi, futhi ihlisa kakhulu izindleko zokufaka, okwenza lolu hlobo lwe-ductunkwork ibe yisixazululo esisebenzayo sezindleko zamaphrojekthi ahlukahlukene.

    Ukubalwa kobude be-welding ubude

    Ukuphikiswa kokugqwala okuthuthukisiwe:

    I-Corrosion iyinkinga enkulu ezinhlelweni zamapayipi, ikakhulukazi ezimbonini eziphatha amakhemikhali nezinto ezilimazayo. I-ASTM A252 Encrandard iqinisekisa ukuthi amapayipi ensimbi anama-welded abonisa ukumelana kahle kokugqwala. Lawa mapayipi anezimbotshana ezivikelayo njenge-epoxy noma i-zinc esebenza njengesithiyo kuma-ejenti asolisayo, ukunweba impilo yabo yenkonzo kanye nokunciphisa izindleko zokulungisa. Lesi sici sizuzisa ikakhulukazi ezisetshenziselwa ezingaphansi komhlaba noma eziphuma olwandle lapho amapayipi evezwa khona izimo ezinokhahlo kwezemvelo.

    Umthamo omkhulu wokuthwala:

    Esinye isimilo esibalulekile se-ASTM A252 Spiral Welded Pipe iyikhono layo elihle kakhulu lomthwalo. Ubuchwepheshe be-Welding Burding obusetshenzisiwe kwinqubo yokukhiqiza bukhulisa amandla wepayipi namandla okumelana nemithwalo esindayo. Noma ngabe kusetshenziswe ebhuloho, izisekelo zezakhiwo noma amapayipi angaphansi komhlaba, la mapayipi ahlinzeka ngobuqotho obuphakeme kakhulu, ehlisa ubungozi bokwehluleka nokuqinisekisa ukuphepha kwesikhathi eside kwezinhlobonhlobo zamaphrojekthi wengqalasizinda.

    Ukusimama Kwezemvelo:

    Ngenkathi lapho ukuvikelwa kwemvelo kuyinto ekhathazayo emhlabeni wonke, ukukhetha izinto zokwakha ezifanele kubalulekile. Kuvunguza insimbi ye-welded Steel Pipe ASTM A252 ihambisana nemikhuba yokwakha esimeme ngenxa yokuqina kwayo nokubuyiselwa kabusha. Amapayipi anempilo yenkonzo ende futhi angavuselelwa kalula ekugcineni kwempilo yabo, anciphise isidingo sokukhishwa okusha kwezinto ezibonakalayo ngenkathi kunciphisa imfucuza kanye nokukhishwa kwekhabhoni.

    Ekuphetheni:

    Kuvunguza insimbi ye-welded Steel Pipe ASTM A252 iguqule imboni yamapayipi ngamandla ayo aphakeme, ukuqina kanye nokusebenza kwezindleko. Lawa mapayipi ahlangana noma adlule amazinga embonini, abenze bakhetho lokuqala ezimbonini eziningi. Amandla alo amahle kakhulu wokuthwala umthwalo kanye nokumelana nokugqwala kuqinisekisa ukuthuthukiswa okuzinzile kwamaphrojekthi wengqalasizinda futhi afake isandla ekuthuthukisweni komkhakha womhlaba. Ngokusebenzisa la mapayipi, amaphrojekthi wokwakha angakhulisa ukusebenza kahle, anciphise izindleko futhi aqinisekise ukuthembeka kwesikhathi eside ngenkathi enamathela ekusimuseni kwemvelo.
