Umbhobho odityanisiweyo we-Spirallicandelo elibalulekileyo kumashishini ahlukeneyo aquka i-oyile negesi, ulwakhiwo kunye neziseko zophuhliso lwamanzi.Le mibhobho yenziwa kusetyenziswa inkqubo ekhethekileyo ebizwa ngokuba yi-spiral welding, ebandakanya ukudityaniswa kwemicu yentsimbi ukwenza imilo ejikelezayo eqhubekayo.Le ndlela yokuvelisa ibonelela ngeenzuzo ezininzi, kubandakanywa amandla aphezulu, ukuqina kunye nokuphumelela kweendleko.Ukongeza, imibhobho ye-spiral welded ihambelana nemigangatho yezizwe ngezizwe efana ne-EN10219 ukuqinisekisa umgangatho kunye nokusebenza kwayo.
EN10219ngumgangatho waseYurophu ochaza iimeko zokuhanjiswa zobugcisa kumacandelo angaphakathi adityanisiweyo adityanisiweyo entsimbi engeyiyo ialloyi kunye nentsimbi ecolekileyo.Lo mgangatho uchaza iimfuno zenkqubo yokuvelisa, iipropathi zezinto eziphathekayo kunye nokunyamezelwa kwe-dimensional ye-spiral welded steel pipes ukuqinisekisa ukufaneleka kwazo kwizicelo zesakhiwo.
Ukuveliswa kwemibhobho yentsimbi edityanisiweyo yentsimbi kuqala kuqala kukhetha iikhoyili zentsimbi ezikumgangatho ophezulu, emva koko zikhulule kwaye ziwondle kumatshini wokuwelda.Umatshini usebenzisa inkqubo yokudibanisa eqhubekayo ukuze udibanise imida yentsimbi yentsimbi, wenze i-spiral seam kunye nobude bombhobho.I-welds ke iphantsi kovavanyo olungonakalisi ukuqinisekisa ukuthembeka kunye namandla abo.Emva kwe-welding, imibhobho ingena kwiinkqubo ezahlukeneyo zokugqiba, kubandakanywa ukulinganisa, ukulungiswa kunye nokuhlolwa, ukuhlangabezana neemfuno ze-EN10219.
Enye yeenzuzo eziphambili ze-spiral welded steel pipe kukukwazi ukumelana noxinzelelo oluphezulu lwangaphakathi nangaphandle, okwenza kube lula ukuthutha ulwelo kunye neegesi kumashishini ahlukeneyo.Ukongezelela, inkqubo ye-welding ye-spiral inokuvelisa imibhobho kwiintlobo ezahlukeneyo zeedamitha kunye nobukhulu, ukubonelela ngoyilo kunye nokuguquguquka kokwakhiwa.Le mibhobho nayo iyamelana nokubola, nto leyo ephucula ngakumbi ubomi obude kunye nokusebenza kwiindawo ezifuna ngamandla.
Ukuthotyelwa kwe-EN10219 kubalulekile ukuqinisekisa umgangatho kunye nokuthembeka kwe-spiral welded steel pipe.Umgangatho ubeka iimfuno ezingqongqo ekubunjweni kwezinto eziphathekayo, iimpawu zomatshini kunye nokunyamezelwa kwe-dimensional ukuqinisekisa ukuba imibhobho ihlangabezana nemigangatho yokusebenza efunekayo kwizicelo zesakhiwo.
Ukongeza, i-EN10219 ikwachaza iinkqubo zovavanyo kunye nesiqinisekiso ekufuneka abavelisi bathobele, kubandakanya novavanyo olungonakalisi lwe-welds, uvavanyo lokusebenza koomatshini kunye nokuhlolwa okubonakalayo.Ngokuthobela le migangatho engqongqo, abavelisi banokubonelela abathengi ngesiqinisekiso somgangatho kunye nokusebenza kombhobho wentsimbi ovundiweyo.
Isishwankathelo, imveliso kunye nemigangatho yemibhobho yentsimbi edityanisiweyo echazwe kwi-EN10219 idlala indima ebalulekileyo ekuqinisekiseni ukuthembeka nokusebenza kwezi zixhobo zibalulekileyo.Ngokusebenzisa inkqubo ye-spiral welding kunye nokubambelela kwimigangatho engqongqo yokuvelisa, abavelisi banokuvelisa umbhobho okumgangatho ophezulu ohlangabezana neemfuno zamashishini ahlukeneyo.Ngenxa yoko, i-EN10219 iba sisikhokelo esixabisekileyo semveliso, uvavanyo kunye nesiqinisekiso semibhobho yentsimbi edityanisiweyo, inegalelo ekusetyenzisweni kwayo ngokubanzi kwiziseko ezingundoqo kunye neeprojekthi zokwakha kwihlabathi jikelele.
