Ipayipi elishiselwe okuvunguzaiyingxenye ebalulekile ezimbonini ezahlukene ezihlanganisa uwoyela negesi, ingqalasizinda yezokwakha kanye neyamanzi.Amapayipi akhiqizwa kusetshenziswa inqubo ekhethekile ebizwa ngokuthi i-spiral welding, ehilela ukuhlanganisa imicu yensimbi ukuze kwakheke ukuthandeka okuqhubekayo.Le ndlela yokukhiqiza inikeza izinzuzo eziningi, okuhlanganisa amandla aphezulu, ukuqina kanye nokusebenza kahle kwezindleko.Ngaphezu kwalokho, amapayipi ashiselwe asontekile athobela izindinganiso zamazwe ngamazwe njenge-EN10219 ukuze kuqinisekiswe ikhwalithi nokusebenza kwawo.
I-EN10219iyindinganiso yaseYurophu ecacisa izimo zobuchwepheshe zokulethwa kwezingxenye ezingenalutho zesakhiwo esishiselwe okubandayo zensimbi engeyona ingxubevange nensimbi ecolisekile.Leli zinga lichaza izidingo zenqubo yokukhiqiza, izakhiwo zezinto ezibonakalayo kanye nokubekezelelana kwe-dimensional kwamapayipi ensimbi ashiselwe ngokuvunguza ukuze kuqinisekiswe ukufaneleka kwawo ekusetshenzisweni kwesakhiwo.
Ukukhiqizwa kwamapayipi ensimbi ayi-spiral ashiselwe kuqala kukhethwa amakhoyili ensimbi ekhwalithi ephezulu, bese ayaqaqa futhi awafake emshinini wokushisela okuvunguzayo.Umshini usebenzisa inqubo yokushisela eqhubekayo ukuze ujoyine imiphetho yomugqa wensimbi, udale umthungo ozungezayo ngobude bepayipi.Ama-welds abe esehlolwa ngokuhlolwa okungabhubhisi ukuze kuqinisekiswe ubuqotho namandla awo.Ngemva kokushiselwa, amapayipi adlulela ezinqubweni zokuphothula ezihlukahlukene, okuhlanganisa usayizi, ukuqondisa nokuhlolwa, ukuze ahlangabezane nezidingo ze-EN10219.
Enye yezinzuzo eziyinhloko zamapayipi ensimbi ashiselwe okuvunguzayo yikhono layo lokumelana nezingcindezi eziphezulu zangaphakathi nezangaphandle, okulenza lifaneleke ukuthutha uketshezi namagesi ezimbonini ezihlukahlukene.Ukwengeza, inqubo yokushisela okuvunguzayo ingakhiqiza amapayipi ngobubanzi obuhlukahlukene nobukhulu, inikeze ukuguquguquka kokuklama nokwakhiwa.Lawa mapayipi ayakwazi ukumelana nokugqwala, okwenza ngcono ukuphila kwawo isikhathi eside nokusebenza kwawo ezindaweni ezinzima.
Ukuhambisana ne-EN10219 kubalulekile ukuze kuqinisekiswe ikhwalithi nokuthembeka kwamapayipi ensimbi ashiselwe ku-spiral.Izinga libeka izidingo eziqinile ekubunjweni kwezinto ezibonakalayo, izakhiwo zemishini kanye nokubekezelelana kobukhulu ukuze kuqinisekiswe ukuthi amapayipi ahlangabezana namazinga okusebenza adingekayo ekusetshenzisweni kwesakhiwo.
Ngaphezu kwalokho, i-EN 10219 iphinde icacise izinqubo zokuhlola nezitifiketi abakhiqizi okufanele bahambisane nazo, okuhlanganisa ukuhlolwa okungabhubhisi kwama-welds, ukuhlolwa kokusebenza kwemishini kanye nokuhlolwa okubukwayo.Ngokunamathela kulezi zindinganiso eziqinile, abakhiqizi banganikeza amakhasimende isiqinisekiso sekhwalithi nokusebenza kwepayipi elishiselwe okuvunguza.
Kafushane, ukukhiqizwa kanye namazinga amapayipi ensimbi ashiselwe okuvunguzayo achazwe ku-EN10219 adlala indima ebalulekile ekuqinisekiseni ukwethembeka nokusebenza kwalezi zingxenye ezibalulekile.Ngokusebenzisa inqubo yokushisela okuvunguzayo nokunamathela ezindinganisweni eziqinile zokukhiqiza, abakhiqizi bangakhiqiza ipayipi lezinga eliphezulu elihlangabezana nezidingo zezimboni ezihlukahlukene.Ngenxa yalokhu, i-EN10219 iba uhlaka olubalulekile lokukhiqiza, ukuhlolwa kanye nesitifiketi samapayipi ensimbi ashiselwe, okunomthelela ekusetshenzisweni kwawo okusabalele kwingqalasizinda ebalulekile namaphrojekthi wokwakha emhlabeni jikelele.
