Yethula:
Emhlabeni wamapayipi ensimbi,ipayipi elishiselwe okuvunguzaidume ngamandla ayo aphakeme, ukuguquguquka kanye nokusebenza kahle kwezindleko.La mapayipi asetshenziswa kakhulu ezimbonini ezahlukene ezifana nowoyela negesi, ukuhanjiswa kwamanzi, ubunjiniyela bezakhiwo kanye nokuthuthukiswa kwengqalasizinda.Ukuqinisekisa ukuhlanganiswa okungenamthungo nokusebenza kahle, kubalulekile ukuqonda imininingwane elawula ipayipi elishiselwe elisontekile.Kule bhulogi, sizocubungula izici ezibalulekile zokucaciswa kwamapayipi ashiselwe, sicacisa ubukhulu bawo, izinto zokwakha kanye nezidingo ezithile.
1. Usayizi wepayipi:
Amapayipi ashiselwe ku-Spiral atholakala ngobukhulu obuhlukahlukene, eqinisekisa ukuhambisana namaphrojekthi ahlukene.Ubukhulu ngokuvamile buhlanganisa ububanzi bangaphandle (OD), ukujiya kodonga (WT), nobude.Ububanzi bangaphandle busuka kumasentimitha angama-20 kuye kwangama-intshi angu-120, futhi ukujiya kodonga kusuka ku-5 mm kuya ku-25 mm.Ngokuya ngobude, izingxenye ezijwayelekile ezijwayelekile zamapayipi ashiselwe ku-spiral angamamitha ayi-6, amamitha ayi-8, namamitha ayi-12 ukuze avumelane nezidingo ezahlukahlukene zobunjiniyela.
2. Izinto:
Ukukhethwa kwezinto zamapayipi e-SSAW kubalulekile futhi kuncike kakhulu ekusetshenzisweni okuhlosiwe kanye nezimo zemvelo.I-Carbon steel isetshenziswa kabanzi ngenxa yamandla ayo, ukuqina, nokumelana nokugqwala.Ngaphezu kwalokho, izinhlelo zokusebenza ezithile ezidinga ukumelana nokugqwala okuthuthukisiwe noma ukumelana nezinga lokushisa eliphezulu, amapayipi enziwe ngensimbi yengxubevange, insimbi engagqwali, noma ezinye izinto ezikhethekile zingasetshenziswa.
3. Inqubo yokukhiqiza:
Ipayipi elishiselwe ku-Spiral likhiqizwa ngenqubo eqhubekayo yokwakheka kwe-spiral kusetshenziswa amakhoyili e-steel strip.Le ndlela iqinisekisa ukufana kokuqina kodonga, ububanzi kanye nobuqotho besakhiwo jikelele.Ikhoyili ifakwa emshinini, oyilolonge ibe yisimo esithandelayo bese ihlanganisa imiphetho.Ubuchwepheshe obuphambili obuhilelekile enqubweni yokukhiqiza buvumela ukulawula okunembile phezu kobukhulu nokusebenza kwepayipi lokugcina.
4. Amazinga ekhwalithi:
Ukuze kuhlangatshezwane namazinga embonini futhi kuqinisekiswe ukwethembeka kwamapayipi ashiselwe okuvunguzayo, kuqaliswa izindlela zokuqinisekisa ikhwalithi ehlukahlukene.Lokhu kufaka phakathi ukuthobela izindinganiso eziqashelwa umhlaba wonke njenge-API 5L, ASTM A252 kanye ne-ISO 3183-3.Ukuhambisana nalokhu kucaciswa kuqinisekisa izakhiwo zemishini, ukwakheka kwamakhemikhali, nokunemba kobukhulu bepayipi.
5. Ukuhlola nokuhlola:
Ukuqinisekisa ubuqotho nokusebenza okuphephile kwepayipi elishiselwe okuvunguzayo, ukuhlolwa okuqinile kanye nezinqubo zokuhlola kuyadingeka.Sebenzisa izindlela zokuhlola ezingalimazi njengokuhlola i-ultrasonic, ukuhlolwa kwe-radiographic nokuhlola ukungena kombala.Lokhu kuhlola kuthola noma yikuphi ukushiyeka kwesakhiwo noma ukungahambisani kwezinto okungase kuthinte ukusebenza nokuqina kwepayipi.Ukwengeza, ukuhlolwa ngokomzimba okufana nokuhlolwa kwe-hydrostatic kwenziwa ukuze kuhlolwe amandla namandla okuthwala ingcindezi yamapayipi.
Ekuphetheni:
Amapayipi ashiselwe ku-Spiral anikeza izinzuzo eziningi ngaphezu kwezinye izinhlobo zamapayipi futhi ukucaciswa kwawo kudlala indima ebalulekile ekugcineni ikhwalithi yawo, ukwethembeka kanye nokuhambisana nezinhlelo zokusebenza ezahlukene.Ukuqonda ubukhulu, izinto zokwakha, izinqubo zokukhiqiza kanye nezindinganiso zekhwalithi ezihambisana nepayipi elishiselwe okuvunguzayo kubalulekile ekuqinisekiseni ukusebenza kahle kanye nesixazululo esingabizi kakhulu.Njengoba ubuchwepheshe buqhubeka nokuthuthuka, imininingwane elawula la mapayipi iyaqhubeka nokuba ngcono, ikhulisa ukusebenza kahle kwawo kanye nokuguquguquka kwezinto ezimbonini ezahlukahlukene.Ngokucubungula lezi zicaciso, onjiniyela nochwepheshe bangenza izinqumo ezinolwazi mayelana nokukhetha nokusetshenziswa kwepayipi elishiselwe elivunguzayo lamaphrojekthi abo.
