    I-Spiral Welded Pipes For Natural Gas Pipelines

    Amapayipi Ashiselwe Okuvunguza Ngamapayipi Egesi Yemvelo Isithombe Esifakiwe
    • I-Spiral Welded Pipes For Natural Gas Pipelines

    Incazelo emfushane:

    I-spiral welded pipe ingumkhiqizo oguquguqukayo ongasetshenziswa ezimbonini nasezinkundleni ezihlukahlukene.Ngobuqotho bayo obuhle kakhulu besakhiwo kanye nokuqina, isibe yingxenye ebalulekile ezinhlelweni zokuhlinzekwa kwamanzi, imboni ye-petrochemical, imboni yamakhemikhali, imboni yamandla kagesi, ukuchelela ngenkasa kwezolimo, kanye nokwakhiwa kwamadolobha.Kungakhathaliseki ukuthi ukudluliswa kwe-liquid, ukudluliswa kwegesi noma izinhloso zesakhiwo, ipayipi elishiselwe elivunguzayo liyisinqumo esithembekile nesisebenzayo.


    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Ipayipi elihlanganisiwe elivunguzayo, elaziwa nangokuthiithubhuweld, ikhiqizwa kusetshenziswa ubuchwepheshe obuphambili bokushisela ukuze kwakhiwe umkhiqizo oqinile.Iqukethe inhlanganisela ezungezayo eqhubekayo eyakhiwe ngamapheshana ensimbi ashisela ndawonye.Lesi sakhiwo esiyingqayizivele sinikeza amandla angenakuqhathaniswa, okwenza kube kuhle ekufuneni izicelo ezifanaimigqa yegesi yemvelo.

    Esinye sezicelo eziyinhloko zamapayipi ashiselwe okuvunguza ukuthuthwa kwegesi yemvelo.Iklanywe ngokukhethekile futhi yakhiwe ukuze imelane nezindawo ezinengcindezi ephezulu ehambisana nokudluliswa kwegesi yemvelo.Amapayipi ashiselwe nge-Spiral aqinisekisa ukulethwa okuphephile nokusebenza kahle kwegesi yemvelo ezimbonini nakubathengi, kuqinisekisa ukuhlinzekwa okuthembekile futhi kuncishiswe noma yikuphi ukuvuza okungaba khona noma izingozi.

    Ngaphezu kwalokho,amapayipi ashiselwe asontekilezibuye zisetshenziswe kabanzi ezinhlelweni zokuhlinzeka ngamanzi kanye ne-drainage.Ukwakhiwa kwayo okungavuzi kanye nokumelana nokugqwala kuyenza ibe inketho efanelekile yokuthutha amanzi esuka emthonjeni ukuya endaweni eya kuyo.Ngenxa yokuqina kwayo, ingakwazi ukumelana nezimo ezinzima ezivamise ukuhlangana nazo ezinhlelweni zokuhlinzekwa kwamanzi, ihlinzeka imiphakathi nezimboni ngezixazululo ezihlala isikhathi eside nezithembekile.

    Amapayipi Okwakheka Kwesigaba Esingenalutho

    Embonini ye-petrochemical, amapayipi ashiselwe ku-spiral adlala indima ebalulekile ekuthuthweni kwegesi, umusi, igesi ye-petroleum ewuketshezi nezinye izinto.Amandla ayo aphezulu kanye nokumelana nokugqwala kuyenza ibe yisinqumo esihle kakhulu sokudlulisa lezi zinto eziguquguqukayo.Kungakhathaliseki ukuthi isitshalo esikhulu se-petrochemical noma ukufakwa okuncane, amapayipi ashiselwe e-spiral aqinisekisa ukuthuthwa okuphephile nokuphumelelayo kwalezi zinsiza ezibalulekile.

    Ngaphezu kwalokho, ukwakheka kwepayipi elishiselwe okuvunguza lisetshenziswa kabanzi.Ivamise ukusetshenziswa njengamashubhu okunqwabelanisa izisekelo kumaphrojekthi wokwakha, ihlinzeka ngokusekelwa okudingekayo nokuzinza.Ukuqina kwepayipi kukwenza kube ukukhetha kokuqala kwamabhuloho, amadokhu, imigwaqo kanye nezakhiwo zokwakha.Amandla abo okumelana nemithwalo esindayo kanye namandla angaphandle aqinisekisa ukuphepha nobuqotho balezi zakhiwo, okwenza kube yingxenye ebalulekile emkhakheni wokwakhiwa kwamadolobha.

    Sengiphetha, i-spiral welded pipe (eyaziwa nangokuthi i-pipe weld) inikeza isisombululo esiguquguqukayo nesihlala isikhathi eside ezimbonini nasezimbonini ezihlukahlukene.Izinhlobonhlobo zezicelo zayo zihlanganisa ubunjiniyela bokuhlinzekwa kwamanzi, imboni ye-petrochemical, imboni yamakhemikhali, imboni yamandla kagesi, ukuchelela ngenkasa kwezolimo, ukwakhiwa kwamadolobha, njll. Kungakhathaliseki ukuthi isetshenziselwa ukuthuthwa koketshezi noma amagesi, noma ngezinhloso zesakhiwo, ipayipi elishiselwe elivunguzayo lithembekile futhi ukukhetha okusebenzayo.Ngamandla ayo angavamile, ukunwebeka nokumelana nokugqwala, isalokhu iyisici esibalulekile embonini yesimanje.
