- Izimo namalungiselelo okucindezela kokuhlolwa kwepayipi lezandla
I.1.Uhlelo lwamapayipi luqediwe futhi luhambisana nezidingo nemithethonqubo yokuklama.
I.2.Igatsha, isiphanyeko kanye nendawo yokubeka ipayipi sekuqediwe, futhi ukutholwa kwe-ray flaw sekufinyelele ngokuphelele ekucacisweni komklamo, futhi ingxenye yokuhlola, i-weld nokunye kufanele kuhlolwe akupendiwe futhi kufakwe incubated.
I.3.I-gauge yokucindezela kokuhlola iqinisekisiwe, ukunemba kusethelwe ku-1.5, futhi inani eliphelele lesilinganiso sethebula kufanele libe izikhathi ezingu-1.5 kuya kwezingu-2 ukucindezela okukhulu kukalwa.
I.4.Ngaphambi kokuhlolwa, uhlelo lokuhlola, imishini kanye nezinamathiselo ngeke kuhileleke ohlelweni lokuhlola, futhi isikhundla sebhodi eliyimpumputhe sisetshenziselwa ukusebenzisa uphawu olumhlophe lwe-lacquer lacquered kanye nerekhodi.
I.5.Amanzi okuhlola kufanele asetshenziswe ngamanzi ahlanzekile, futhi okuqukethwe kwe-chloride ion emanzini akumele kudlule u-25 × 10-6 (25 ppm).
I.6.Ipayipi lesikhashana lokuhlolwa liyaqiniswa, futhi ukuphepha nokwethembeka kufanele kuhlolwe.
I.7.Hlola ukuthi wonke ama-valve epayipi asesimweni esivulekile yini, ukuthi ama-spacers ayengeziwe, futhi umnyombo we-valve ohlehlisayo uzokhishwa, futhi ngemva kokuhlanzwa kungasethwa kabusha.
2. Ukuhlolwa kwepayipi lokucubungula
2.1.Ingcindezi yokuhlolwa kwamapayipi izikhathi ezingu-1.5 kunengcindezi yokuklama.
2.2. Lapho ipayipi nemishini kuhlolwa njengesistimu, ingcindezi yokuhlola yepayipi ilingana noma ingaphansi kokucindezela kokuhlolwa kwedivayisi, futhi ingcindezi yokuhlola yedivayisi ayikho ngaphansi kwezikhathi eziyi-1.15 kunengcindezi yokuklama ipayipi, futhi ingahlolwa ngokuvumelana nokucindezela kokuhlolwa kwemishini.
2.3.Wisikhukhukazi siyajovwa, umoya kufanele uphele, indawo yokukhipha umoya kufanele ibe yindawo ephakeme kakhulu yepayipi, bese wengeza i-valve yokukhipha umoya.
2.4. Ngamapayipi anomehluko omkhulu, ingcindezi emile yendawo yokuhlola kufanele ikalwe ekucindezelweni kokuhlola.Ukucindezela kokuhlolwa kwepayipi eliwuketshezi kufanele kube ngaphansi kwengcindezi endaweni ephakeme kakhulu, kodwa ukucindezela kwephuzu eliphansi kakhulu akufanele kudlule izingxenye zeshubhu.
2.5. Lapho ukucindezela kucindezelwa, i-boost kufanele ihambe kancane, futhi ngemva kokuba ingcindezi yokuhlola ifinyelelwe, ilawulwa ngamaminithi angu-10, futhi akukho deformation ngaphandle kokuvuza.Ukucindezela kokuhlola kwehla ekucindezelweni kokuklama, kumisa imizuzu engu-30, futhi ingcindezi ayiwi, akukho ukuvuza okufanelekile.
2.6. Ngemuva kokuhlolwa, ipuleti eyimpumputhe kufanele isuswe ngesikhathi, futhi amanzi abekwe, futhi ukucindezela okungalungile kufanele kuvinjwe uma kukhishwe, futhi akufanele kukhishwe amanzi.Lapho ukuvuza kutholakala ngesikhathi sokuhlolwa, akufanele kusetshenzwe, ngemva kokuqeda isici, kufanele kuhlolwe kabusha.
2.7.Ukuhlolwa kokuvuza kwenziwa ngemva kokuhlolwa kwengcindezi, futhi indawo yokuhlola yasebenzisa umoya ocindezelweyo.
2.8. Ukucindezela kokuhlolwa kokuvuza kuklanyelwe ukuklama ingcindezi, ukuhlolwa kokuvuza kufanele kugxile ekuhloleni isigcwalisi, i-flange noma amalunga anentambo, khipha i-valve, i-valve yokukhipha amanzi, i-valve yokukhipha amanzi, njll., ngokuhlola i-ejenti egwebuzelayo ngaphandle kokuvuza.
3. ukuhlanza ipayipi nokuhlanza
3.1. Izidingo zobuchwepheshe bokucubungula
3.1.1. Ipayipi lenqubo kufanele lihlukaniswe futhi lihlanzwe (okubizwa ngokuthi ukuhlanzwa).
3.1.2. Indlela yokuphefumula inqunywa ngokuvumelana nezidingo zokusetshenziswa kwepayipi, inqubo engcolile yendawo yokusebenza kanye nepayipi yangaphakathi inqunywa, futhi ukulandelana kokumisa izinwele ngokuvamile kwenziwa ngokuhambisana nomphathi, ipayipi legatsha. , kanye ne-tube yokukhipha.
3.1.3. Ngaphambi kokuvuthela, ithuluzi elingaphakathi kwesistimu kufanele livikelwe futhi likhiphe i-orifice plate, i-valve yokulungisa isihlungi kanye nomzimba we-valve ehoxisiwe, njll., ngendlela efanele, nokunye okunjalo.
3.1.4. Lapho uhlanza, ukungcola kwepayipi akufanele kungene emishini, futhi ukungcola okukhishwe kudivayisi ngeke kungene ipayipi, i-valve flange ingeziwe.
3.1.5. Ukuhlanzwa kwamapayipi kufanele kube nokugeleza okwanele, futhi ingcindezi yokuhlanza akufanele idlule ingcindezi yokuklama, futhi izinga lokugeleza ngokuvamile alikho ngaphansi kuka-20 m / s.Lapho uhlanza, sebenzisa isando sokhuni ukuze ushaye ithubhu, futhi ugxile ekushiseleni nangaphansi kwepayipi, kodwa akumelwe ukulimaze ipayipi .
3.1.6. Igatsha lepayipi kufanele licatshangelwe ngaphambi kokushaywa, futhi ukugoqa kwe-hanger kufanele kuqiniswe uma kunesidingo.
3.2. Ukuhlanzwa kwamapayipi, indlela yokuhlanza
3.2.1. Ukugeza ngamanzi: Indawo yokusebenza ipayipi lohlelo lwamanzi.Ukugeza ngamanzi kungase kufinyelele izinga lokugeleza okuphezulu noma kungabi ngaphansi kuka-1.5 m / s ku-tube.Ifanelekele ukuthekelisa amanzi kanye nokungafihli ngokungena.Ngemuva kokuthi ipayipi ihlanjululwe, amanzi kufanele aphele ngesikhathi.
3.2.2.Ukuhlanzwa komoya: Indawo yokusebenza ihlanzwa kancane kancane ngezingxenye zomoya ezicindezelwe zamapayipi egesi.Uma uhlangana ne-valve, kufanele ususe i-flange yangaphambili ebhodini le-docking, bese usetha kabusha ngemva kokushaywa kwepayipi.Ukucindezela akumele kudlule ingcindezi yokuklama isitsha kanye nepayipi, futhi izinga lokugeleza akufanele libe ngaphansi kwama-20 m / s.Ngesikhathi sokuhlanza umoya, lapho igesi yokukhipha umoya ingabhemi, imbobo yokukhipha umoya ifakwa embotsheni yokukhipha umoya ukuze kuhlolwe ithagethi yokhuni ene-lacquered, futhi akukho ukugqwala, uthuli, umswakama, nezinye izibi epuleti eliqondiwe emizuzwini emi-5.
3.2.3.I-steam purge: Indawo yokusebenza ihlanzwa ngesitimu epayipini lesitimu.Umusi uhlanzwa ngaphambi kokuba ishubhu elifudumele lihambe kancane, bese liphola ngokwemvelo lifike ezingeni lokushisa elizungezile, bese uphakamisa ishubhu elifudumele, ukhiphe ukuhlanza kwesibili, ngakho ukuphindaphinda ngokuvamile akubi ngaphansi kwezikhathi ezintathu.I-exhaust gas ekuhlanzeni umhwamuko itshekele phezulu, futhi uphawu ludonsa amehlo.I-diameter yepayipi yokukhipha akufanele ibe ngaphansi kobubanzi be-tube yokuhlanza.Izinga elifanelekayo: Okuhloswe ukushintshwa okuphindwe kabili izikhathi ezimbili ezilandelanayo, njengamabala abonakala ngeso lenyama kusayizi wepuleti eliqondiwe ngaphansi kuka-φ 0.6mm, ukujula kungu-1 / cm2;isikhathi sokuhlanza siyimizuzu eyi-15 (okungukuthi emibili Uma kudlula, kuyadluliswa.
