    Kuvunguza amapayipi we-welded amapayipi wegesi wemvelo

    Kuvunguza amapayipi we-welded amapayipi wegesi wemvelo afakiwe isithombe
    • Kuvunguza amapayipi we-welded amapayipi wegesi wemvelo

    Incazelo emfushane:

    Kuvunguza ipayipi we-welded ngumkhiqizo oguquguqukayo ongasetshenziswa ezimbonini nasezinkameni ezahlukahlukene. Ngobuqotho bayo obuhle kakhulu bokuqina nokuqina, sekuyinto ebaluleke kakhulu kumaphrojekthi wokuhlinzekwa kwamanzi, imboni ye-petrochemical, imboni yamandla amakhemikhali, imboni yamandla kagesi, ukunisela kwezolimo, kanye nokwakhiwa kwezolimo. Noma ngabe ukudluliswa koketshezi, ukudluliselwa kwegesi noma izinhloso zesakhiwo, ipayipi elivuthayo i-Spiral Welded liyindlela ethembekile futhi ephumelelayo.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Kuvunguza ipayipi le-welded, eyaziwa nangokuthiithumbubulala phambili, akhiqizwa kusetshenziswa ubuchwepheshe obuthuthukisiwe be-welding ukudala umkhiqizo oqinile. Siqukethe okuhlangene okuqhubekayo okuhlangene okwakheke ngemichilo yensimbi enomoya enomoya. Lesi sakhiwo esiyingqayizivele sinikeza amandla angenakuqhathaniswa, okwenza kube kuhle ngezicelo ezifunwayo ezifanaImigqa yegesi yemvelo.

    Enye yezinhlelo zokusebenza eziphambili zepayipi le-welded welded yinto yokuhamba yegesi yemvelo. Iklanyelwe ngokukhethekile futhi yakhiqizwa ukumelana nezimo eziphakeme kakhulu ezihambisana nokudluliselwa kwegesi yemvelo. Amapayipi we-welded we-welded aqinisekisa ukulethwa okuphephile futhi okusebenzayo kwegesi yemvelo ezimbonini nakwabathengi, eqinisekisa ukulethwa okuthembekile futhi anciphise noma yikuphi ukuvuza noma izingozi ezingaba khona.

    Ngaphezu kwalokho,Kuvunguza amapayipi we-weldedfuthi zisetshenziswa kabanzi ekuhlinzekweni kwamanzi nezinhlelo zokudonsa amanzi. Ukumelana kwalo okuvuzayo nokuphikisana nokugqwala kwenza kube yikhethelo eliphelele lokuhambisa amanzi kusuka emthonjeni kuya lapho uya khona. Ngenxa yokuqina kwayo, kungamelana nezimo ezinzima ezivame ukuhlangana namaphrojekthi wokuhlinzekwa kwamanzi, ukuhlinzeka ngemiphakathi nezimboni ezihlala isikhathi eside, ezinokwethenjelwa.

    Amapayipi angenazibalo

    Embonini ye-petrochemical, amapayipi we-welded ane-welded adlala indima ebalulekile ekuthuthweni kwegesi, umusi, ugesi we-liquefied petroleum kanye nezinye izinto. Amandla ayo aphezulu kanye nokumelana nokugqwala kwenza kube yisinqumo esihle kakhulu sokudlulisela lezi zinto eziguqukayo. Noma ngabe kuyisitshalo esikhulu se-petrochemical noma ukufakwa okuncane, amapayipi we-welded anempilo aqinisekisa ukuthutha okuphephile nangokufanele kwalezi zinsiza ezibalulekile.

    Ngaphezu kwalokho, ukwakheka kwepayipi le-welded welded kusetshenziswa kabanzi. Imvamisa isetshenziswa njengamashubhu wokuphamba izisekelo kumaphrojekthi wokwakha, ukuhlinzeka ukwesekwa okudingekayo nokuqina. Ukuqina kwepayipi nakho kwenza kube ukukhetha kokuqala kwamabhuloho, ama-dock, imigwaqo kanye nezinhlaka zokwakha. Amandla abo okubekezelela imithwalo esindayo namabutho angaphandle aqinisekisa ukuphepha nobuqotho balezi zinhlaka, abenze into ebaluleke kakhulu emkhakheni wokwakha amadolobha.

    Ekuphetheni, ipayipi elivuthayo livunguza (elaziwa nangokuthi ipayipi weWeld) linikeza isisombululo esiguquguqukayo futhi esiqinile sezimboni ezahlukahlukene kanye nemikhakha. Uhla lwayo olubanzi lwezicelo lubandakanya ukuhlinzekelwa kwamanzi, imboni ye-petrochemical, imboni yamandla amakhemikhali, ukunisela kwezolimo, njll. Noma ngabe ipayipi le-welderal, ipayipi elinokwenziwa kahle. Ngamandla ayo ahlukile, ukumelana nokugqwala nokuphikiswa, kuhlala kuyinto ebalulekile embonini yanamuhla.
