Ipayipi elihlanganisiwe elihlanganisiweiyisici esibalulekile ezimbonini ezahlukahlukene okuhlanganisa uwoyela negesi, ukwakhiwa kanye nengqalasizinda yamanzi. Amapayipi akhiqizwa kusetshenziswa inqubo ekhethekile ebizwa ngokuthi i-spiral welding, ehilela ukuhlanganisa imichilo yensimbi ukudala isimo esiqhubekayo se-spiral. Le ndlela yokukhiqiza inikeza izinzuzo eziningi, okuhlanganisa amandla aphezulu, ukuqina kanye nokusebenza kahle kwezindleko. Ngaphezu kwalokho, amapayipi e-spiral weld ahambisana nezindinganiso zomhlaba wonke ezifana ne-EN10219 ukuqinisekisa ikhwalithi nokusebenza kwawo.
EN10219iyindinganiso yaseYurophu echaza izimo zokulethwa kobuchwepheshe zezingxenye ezingenalutho ezakhiwe ngokushelelayo zensimbi engeyona i-alloy kanye nensimbi ecolekile. Le ndinganiso ichaza izidingo zenqubo yokukhiqiza, izakhiwo zezinto kanye nokubekezelelana kobukhulu bamapayipi ensimbi ashelelayo ajikelezayo ukuqinisekisa ukuthi afanelekile ukusetshenziswa kwesakhiwo.
Ukukhiqizwa kwamapayipi ensimbi ahlanganisiwe nge-spiral kuqala kukhetha ama-coil ensimbi asezingeni eliphezulu, bese evula ama-coil bese ewafaka emshinini wokushisela nge-spiral. Umshini usebenzisa inqubo yokushisela eqhubekayo ukuhlanganisa imiphetho yomcu wensimbi, okudala umthungo ojikelezayo ubude bepayipi. Ama-weld abe esehlolwa ngendlela engonakalisi ukuqinisekisa ubuqotho bawo namandla awo. Ngemva kokushisela, amapayipi adlula ezinqubweni ezahlukene zokuqeda, okuhlanganisa usayizi, ukuqondisa kanye nokuhlolwa, ukuze kuhlangatshezwane nezidingo ze-EN10219.
Enye yezinzuzo eziyinhloko zepayipi lensimbi elihlanganisiwe elijikelezayo yikhono lalo lokubekezelela ukucindezeleka okuphezulu kwangaphakathi nangaphandle, okwenza lifanelekele ukuthutha uketshezi namagesi ezimbonini ezahlukahlukene. Ngaphezu kwalokho, inqubo yokushisela ejikelezayo ingakhiqiza amapayipi anobubanzi nobukhulu obuhlukahlukene, okuhlinzeka ngokuguquguquka komklamo nokwakhiwa. Lawa mapayipi nawo amelana nokugqwala, okuthuthukisa kakhulu isikhathi sawo sokusebenza kahle ezindaweni ezidinga amandla amaningi.
Ukuhambisana ne-EN10219 kubalulekile ukuqinisekisa ikhwalithi nokuthembeka kwamapayipi ensimbi ahlanganisiwe ajikelezayo. Indinganiso ibeka izidingo eziqinile ekwakhiweni kwezinto, izakhiwo zemishini kanye nokubekezelelana kobukhulu ukuqinisekisa ukuthi amapayipi ahlangabezana nezindinganiso zokusebenza ezidingekayo ekusetshenzisweni kwesakhiwo.
Ngaphezu kwalokho, i-EN10219 iphinda ichaze izinqubo zokuhlola nokuqinisekisa okumele abakhiqizi bazilandele, okuhlanganisa ukuhlolwa kokushisela okungabhubhisi, ukuhlolwa kokusebenza kwemishini kanye nokuhlolwa okubonakalayo. Ngokunamathela kulezi zindinganiso eziqinile, abakhiqizi banganikeza amakhasimende isiqinisekiso sekhwalithi kanye nokusebenza kwepayipi lensimbi elishisiwe elijikelezayo.
Ngamafuphi, ukukhiqizwa kanye nezindinganiso zamapayipi ensimbi ahlanganisiwe ahlelwe ku-EN10219 kudlala indima ebalulekile ekuqinisekiseni ukuthembeka nokusebenza kwalezi zingxenye ezibalulekile. Ngokusebenzisa inqubo yokushisela okujikelezayo kanye nokunamathela ezindinganisweni zokukhiqiza eziqinile, abakhiqizi bangakhiqiza amapayipi asezingeni eliphezulu ahlangabezana nezidingo zezimboni ezahlukene. Ngenxa yalokho, i-EN10219 iba uhlaka oluwusizo lokukhiqizwa, ukuhlolwa kanye nokuqinisekiswa kwamapayipi ensimbi ahlanganisiwe ahlanganisiwe, okufaka isandla ekusetshenzisweni kwawo kabanzi kwingqalasizinda ebalulekile kanye namaphrojekthi okwakha emhlabeni jikelele.
