Ipayipi Lepulasitiki Elihlanganiswe Ngaphakathi Nangaphandle Elihlanganisiwe, Izinzuzo Zomkhiqizo
Ngamandla aphezulu emishini, efanelekayo endaweni enokhahlo;
I-coating yangaphakathi nengaphandle ingavimbela i-oxidation yensimbi futhi inokumelana nokugqwala kwamakhemikhali okuhle.
I-coating inokunamathela okuqinile, amandla aphezulu okubopha kanye nokumelana nomthelela omuhle.
I-coefficient ye-roughness ephansi kanye ne-friction coefficient, ukumelana okuhle kakhulu nokunamathela komzimba wangaphandle;
Ukungagugi, impilo ende yesevisi, elungele ukulethwa kwamanzi angcwatshwe.
I-Plastic Coated Ngaphakathi Nangaphandle Ipayipi Elihlanganisiwe, Izindlela Zokuhlola
Ukuhlola okubonakalayo
Hlola ngokubukeka ikhwalithi yokubukeka kwepayipi lensimbi eboshwe, futhi imiphumela yokuhlolwa izohambisana nezinhlinzeko ze-5.1.
Isilinganiso sobukhulu
Izingxenye ezimbili eziphambanayo zobude obuhlukene zithathwa emikhawulweni yomibili yepayipi yensimbi eboshwe.Esigabeni ngasinye esiphambanayo, ukujiya kokumboza kunoma yimaphi amaphuzu amane aphambana ngokuqondile nesiyingi kukalwa ngegeji yokuqina kazibuthe.Imiphumela yokuhlolwa izohambisana nezinhlinzeko zika-5.4.
Ukuhlolwa kwe-Pinhole
Ubude besampula yesigaba samapayipi bungaba ngu-1000 mm.Ukumbozwa kweshubhu lensimbi kuhlolwa umtshina wokuvuza kwenhlansi ngaphansi kwe-voltage yokuhlola eshiwo.Ugqinsi lwe-coating lungaphansi kuka-0.4mm, i-voltage yokuhlola ingu-1500 V, ukushuba kokumboza kungaphezu kuka-0.4mm, futhi i-voltage yokuhlola ingu-2000 V. Hlola ukuthi i-spark kagesi iyakhiqizwa futhi umphumela wokuhlola kufanele uhambisane no-5.5.
Ukuhlolwa kokunamathela
Ukuhlolwa kokunamathela kuzokwenziwa ngokuya nge-7.4.2 ye-CJ/T 120-2008, futhi imiphumela yokuhlolwa izohambisana no-5.6.
Ukuhlolwa kokugoba
Goba ukuhlolwa for camera steel pipe DN≤50mm.Ubude besampula yesigaba samapayipi (1200±100) mm.
Ezingeni lokushisa elingu-(20±5) ℃, izikhathi ezingu-8 zobubanzi obujwayelekile bepayipi lensimbi njenge-radius yokugoba, i-engeli egobayo engu-30O, ukugoba i-bender yepayipi noma iyafa.Lapho ukuhlolwa kokugoba, akukho ukugcwalisa ku-tube, futhi i-weld itholakala ohlangothini lwendawo egobayo eyinhloko.
Ngemva kokuhlolwa, sika isifanekiso phakathi kwe-arc egobile ukuze uhlole ukunamathela kwangaphakathi, futhi imiphumela yokuhlolwa kufanele ihambisane nezinhlinzeko ze-5.7.
Ukuhlolwa kokucaba
DN> Ishubhu yensimbi enamamilimitha angu-50 izocindezelwa.Ubude besampula yesigaba samapayipi (50±10) mm.
Isifanekiso safakwa phakathi kwamapuleti amabili ezingeni lokushisa elingu-(20±5) ℃, futhi sacindezelwa kancane kancane emshinini wokuhlola ukucindezela kwaze kwaba yilapho ibanga phakathi kwamapuleti amabili libe izingxenye ezine kwezinhlanu zobubanzi obungaphandle besampula.I-seam ehlanganisiwe yepayipi yensimbi eboshwe yayincike ekuqondeni kokufakwa komthwalo.Ngemuva kokuhlolwa, ukunameka kwangaphakathi kuzobhekwa futhi imiphumela yokuhlolwa izohambisana no-5.8.
Ukuhlolwa komthelela
Isampula elingaba ngu-100 mm ubude lasikwa kunoma iyiphi indawo yepayipi lensimbi eliboshwe, futhi ukuhlolwa komthelela kwenziwa ngokuvumelana nezinhlinzeko eziseThebulani 2 ezingeni lokushisa elingu-(20±5) ℃ ukuze kubonwe umonakalo wento engaphakathi. .Ngesikhathi sokuhlolwa, i-weld izoba ngakolunye uhlangothi lwendawo yomthelela, futhi umphumela wokuhlola uzohambisana nezinhlinzeko ze-5.9.

Izisetshenziswa zokuhlola umthelela
Vacuum test
Ubude besampula yesigaba samapayipi (500±50) mm.Sebenzisa izinyathelo ezifanele zokuvimbela ukungena nokuphuma kwepayipi, futhi kancane kancane ukwandisa ukucindezela okungalungile kusuka ku-inlet kuya ku-660 mm hg, gcina i-1 min.Ngemuva kokuhlolwa, hlola ukunamathela kwangaphakathi, futhi imiphumela yokuhlolwa kufanele ihambisane nezinhlinzeko ze-5.10.
Ukuhlolwa kwezinga lokushisa eliphezulu
Ubude besampula yesigaba samapayipi babungu-(100±10) mm.Isifanekiso safakwa ku-incubator futhi sishisiswe ku-(300±5) ℃ ihora elingu-1.Khona-ke yayikhishwa futhi ipholiswe ngokwemvelo ekushiseni okujwayelekile.Ngemuva kokuhlolwa, khipha isampula bese uhlola ukunamathela kwangaphakathi (ukubukeka okumnyama nokumnyama kuvunyelwe), futhi imiphumela yokuhlolwa kufanele ihambisane ne-5.11.
Ukuhlolwa kwezinga lokushisa eliphansi
Isifanekiso sesigaba samapayipi sasingu-(100±10) mm ngosayizi nangobude.Isifanekiso safakwa egunjini le-cryogenic, sipholile ku-(-30±2) ℃ futhi sigcinwe ezingeni lokushisa elingashintshi ihora elingu-1.Yabe isikhishwa futhi ibekwe ezingeni lokushisa (20±5) ℃ for (4-7) h.Ekupheleni kwesikhathi sokuhlolwa, isifanekiso sizokhishwa ukuze sihlole ukunamathela kwangaphakathi, futhi ukuhlolwa kokunamathela kuzokwenziwa ngokuvumelana nezinhlinzeko ze-6.4, futhi imiphumela yokuhlolwa izohambisana nezinhlinzeko ze-5.12.
Ukuhlolwa komjikelezo wengcindezi
Ubude besampula yesigaba samapayipi babungu-(500±50) mm.Kwasetshenziswa izinyathelo ezifanele ukuvimba indawo yokungena nokuphuma kwepayipi, futhi ipayipi lalixhunywe nohlelo lokuphakelwa kwamanzi.Amanzi agcwaliswa ukuze kukhishwe umoya, kwase kwenziwa ukuhlola okungu-3000 okushintshanayo kwe-hydrostatic kusuka ku-(0.4±0.1) MPa kuya ku-MPa, futhi isikhathi sokuhlolwa ngakunye sasingekho ngaphezu kwe-2 s.Ngemuva kokuhlolwa, ukunamathela kwangaphakathi kuzobhekwa futhi ukuhlolwa kokunamathela kuzokwenziwa ngokuvumelana nezinhlinzeko ze-6.4, futhi imiphumela yokuhlolwa izohambisana nezinhlinzeko ze-5.13.
Ukuhlolwa komjikelezo wezinga lokushisa
Ubude besampula yesigaba samapayipi babungu-(500±50) mm.Ama-specimens abekwe amahora angama-24 ezingeni lokushisa ngalinye ngendlela elandelayo:
(50±2) ℃;
(-10±2) ℃;
(50±2) ℃;
(-10±2) ℃;
(50±2) ℃;
(-10±2) ℃.
Ngemva kokuhlolwa, isifanekiso safakwa endaweni enezinga lokushisa elingu-(20±5) ℃ amahora angu-24.I-coating yangaphakathi ihlolwe futhi ukuhlolwa kokunamathela kwenziwa ngokuvumelana nezinhlinzeko ze-6.4.Imiphumela yokuhlolwa kufanele ihambisane nezinhlinzeko zika-5.14.
Ukuhlolwa kokuguga kwamanzi afudumele
Ubukhulu nobude besampula yesigaba samapayipi cishe ku-100 mm.Izingxenye eziveziwe kuzo zombili iziphetho zesigaba sepayipi kufanele ziphathwe nge-anticorrosion.Ingxenye yamapayipi kufanele icwiliswe emanzini acwengekile ku-(70±2) ℃ izinsuku ezingama-30.
