Yethula:
Ipayipi elishiselwe i-Spiral liyingxenye ebalulekile kumaphrojekthi wengqalasizinda ehlukene, okuhlanganisa amapayipi kawoyela negesi, amasistimu okulethwa kwamanzi, kanye nokusetshenziswa kwesakhiwo.Njenganoma yimuphi umkhiqizo owenziwe ngobunjiniyela, imininingwane ethile kufanele ilandelwe ukuze kuqinisekiswe ukusebenza kahle nokuthembeka kwala mapayipi.Kule bhulogi, sizohlola ubunkimbinkimbi bespiral ashiselwe ipayipi imininingwaneukuhlinzeka ngomhlahlandlela ophelele wokuqonda kangcono lo mkhiqizo obalulekile wezimboni.
1. Incazelo kanye nezinzuzo:
Indlela yokukhiqiza yeipayipi elishiselwe okuvunguzaukushisela umugqa wensimbi ogoqiwe oshisayo ube wumumo oyisipesheli ngokwenza ukuzungeza okuqhubekayo.Imiphetho yestrip ihlanganiswe ndawonye kusetshenziswa i-arc welding engaphansi kwezinhlangothi ezimbili (i-DSAW) ukuze yakhe ipayipi lamandla aphezulu elinokuqina okuthuthukisiwe kanye nokumelana nokuguga.Izinzuzo eziyinhloko zamapayipi ashiselwe okuvunguza zihlanganisa ubuqotho besakhiwo esihle kakhulu, amandla afanayo phakathi nobude bepayipi, nekhono lokumelana nezingcindezi eziphezulu zangaphakathi.
2. Ububanzi nokuqina kodonga:
Ukucaciswa kwamapayipi ashiselwe okuvunguza kufaka phakathi imingcele ehlukahlukene, okubaluleke kakhulu okuyi-diameter nokuqina kodonga lwepayipi.Lezi zilinganiso zincike ohlelweni oluhlosiwe nezimo zokusebenza.Ngokuvamile, ipayipi elishiselwe elisontekile liyatholakala kububanzi obukhulu bepayipi kunepayipi elishiselwe ngomthungo noma eliqondile, elisukela kumayintshi angu-8 ukuya kwangu-126 amayintshi (203.2 kuya ku-3200 mm) noma ngaphezulu.Ugqinsi lwezindonga lusuka ku-6 mm luye ku-25.4 mm noma ngaphezulu.
3. Ibanga lensimbi nokwakheka kwamakhemikhali:
Ukukhethwa kwebanga lensimbi kanye nokwakheka kwamakhemikhali kudlala indima ebalulekile ekunqumeni izakhiwo zemishini kanye nokumelana nokugqwala kwamapayipi ashiselwe.Amamaki ensimbi asetshenziswa kakhulu amapayipi okuvunguza ahlanganisa uchungechunge lwe-API 5L X, i-ASTM A252 amabanga 2 no-3, kanye ne-ASTM A139 amabanga B no-C. Lawa mabanga ensimbi anqunywa ngokusekelwe kumandla esivuno kanye nokulingana kwekhabhoni ukuze kuqinisekiswe ukusebenza kahle ezinhlelweni ezithile.
4. Ukuhlola nokuhlola:
Ukuze kuqinisekiswe ikhwalithi nokuthembeka kwamapayipi ashiselwe okuvunguza, abakhiqizi bahambisana nezinqubo eziqinile zokuhlola nokuhlola.Ukuhlola okubalulekile okwenziwayo kufaka phakathi ukuhlolwa kwe-hydrostatic, ukuhlola okungabhubhisi (njengokuhlolwa kwe-ultrasonic noma nge-radiographic) nokuhlolwa kwemishini (ukushuba, ukuvunwa kanye nokuhlolwa komthelela).Lezi zivivinyo ziqinisekisa ukuthi amapayipi ahlangabezana namandla adingekayo, ubukhulu kanye namazinga okuvuza.
5. Ukunameka okungaphezulu nokuvikela:
Ukuze uvikele amapayipi ashiselwe okuvunguza ekugqwaleni nezinye izici zangaphandle, kunezindlela ezihlukahlukene zokumboza indawo engaphezulu.Lezi zembatho zingabandakanya i-epoxy, i-coal tar koqweqwe lwawo noma i-polyethylene, phakathi kokunye.Ukwengeza, izindlela zokuvikela i-cathodic ezifana nama-anode omhlatshelo noma amasistimu amanje ahlaba umxhwele angasetshenziswa ukuvikela amapayipi.
Ekuphetheni:
Ukuqonda ukucaciswa kwamapayipi ashiselwe kubalulekile konjiniyela, abaphathi bephrojekthi kanye nababambiqhaza ababambe iqhaza kumaphrojekthi wengqalasizinda.Ngokucabangela ububanzi, ubukhulu bodonga, izinga lensimbi, ukuhlolwa nokuvikelwa kwendawo, ungaqinisekisa ukuthi ipayipi ihlangabezana nezindinganiso zokusebenza ezidingekayo.Ukuhambisana kahle namakhodi akuqinisekisi nje kuphela isikhathi eside nokuphepha kwesistimu yakho yamapayipi, kodwa futhi kuqinisekisa ukuthuthwa okuthembekile koketshezi, amagesi nezinye izinto.Ngokunaka imininingwane, onjiniyela nababambiqhaza bangafinyelela imiphumela eyimpumelelo yephrojekthi ngenkathi behlangabezana namazinga nemithethonqubo edingekayo.
