Imboni yamapayipi okuvunguza kufanele yenziwe ngaphambi kokuhlolwa kokusebenza kwemishini kanye nokuhlolwa kokucaba, nokuhlolwa kokuvutha, kanye nokufeza izidingo ezijwayelekile. Indlela yokuhlola ikhwalithi yepayipi lensimbi ye-Spiral imi kanje:
1, Kusukela ebusweni bayo, lokho kuwukuhlola okubukwayo. Ukuhlolwa okubonwayo kwamalunga ashiselwe kuyinqubo elula kodwa indlela yokuhlola esetshenziswa kabanzi iyingxenye ebalulekile yokuhlolwa komkhiqizo, amaphutha amakhulu kanye nokuchezuka kutholakala ebusweni bosayizi wokushisela. Ngokuvamile ngeso lenyama, ngemodeli evamile, igeji kanye namathuluzi okuhlola njengengilazi yokukhulisa. Uma i-weld surface ingasebenzi kahle, kungase kube khona amaphutha angaphakathi.

2, Izindlela zokuhlola ngokomzimba: indlela yokuhlola ngokomzimba ukusebenzisa isivivinyo sezinto ezibonakalayo noma indlela yokuhlola. Noma ngaphakathi kokuhlolwa kokukhubazeka kwezinto ezibonakalayo, futhi ngokuvamile kusetshenziswa izindlela ze-NDT. Ukutholwa kwamaphutha e-NDT, ukutholwa kwemisebe, ukuhlolwa kokungena, ukuhlolwa kazibuthe nokunye.

3, Ukuhlolwa kwamandla emikhumbi yokucindezela: imikhumbi yokucindezela, ngaphezu kokuhlolwa kokuqina, kodwa nokuhlolwa kwamandla. Kukhona ukuhlolwa okuvamile kokuhlolwa kwe-hydraulic kanye nomfutho womoya. Angahlolwa ekusebenzeni ngaphansi kwemikhumbi yengcindezi kanye nokuhlangana kwamapayipi okushisela. Ukuhlolwa kwengcindezi ye-Hydrostatic kuzwela kakhulu kunejubane lokuhlola futhi, ngesikhathi esifanayo ngemva kokuba imikhiqizo yokuhlola ingamoshi ukwelashwa kwamanzi, izinkinga zokugeleza kwamanzi zomkhiqizo zisebenza ngokukhethekile. Kodwa ingozi inkulu kunokuhlolwa kwengcindezi yokuhlola. Uma ihlolwa, kufanele ihambisane nezinyathelo ezifanele zokuphepha ukuze kuvinjelwe izingozi ngesikhathi sokuhlolwa.

I-4, Ukuhlolwa okuhlangene: uketshezi noma igesi yokugcina isitsha sokushisela, okungewona amaphutha aminyene weld, njengokuqhekeka okungena ngaphakathi, ama-pores, i-slag, ukungena okungaphelele kwezicubu ezixekethile nokunye okunjalo, kungasetshenziswa ukuthola ukuhlolwa kokuminyana. Izindlela zokuhlola ukuqina yilezi: ukuhlolwa kukaphalafini, ukuthwala ukuhlolwa kwamanzi, amanzi azohlola.

I-5, Ukuhlolwa kwe-hydrostatic kufanele kwenziwe ukuhlolwa kwepayipi ngalinye le-hydrostatic ngaphandle kokuvuza, cindezela ukuhlolwa kwengcindezi Bala P = 2ST / D lapho ukuhlolwa kokucindezeleka kwe-S-hydrostatic test Mpa, ukuhlolwa kokucindezeleka kokuhlolwa kwe-hydrostatic ngokusho kwezinga lensimbi elihambisanayo licacisa izinga elincane lesivuno ( I-Q235 ingu-235Mpa) 60% wokukhethiwe. Isikhathi sokulawula: D <508 ingcindezi yokuhlola ebambe isikhathi esingaphansi kwamasekhondi angu-5; D≥508 ingcindezi yokuhlola ebambe isikhathi esingaphansi kwamasekhondi angu-10 4, ukuhlolwa okungabhubhisi kwe-steel welding seam, i-strip end weld kanye namajoyinti ajikelezayo kufanele kuhlolwe i-X-ray noma i-ultrasonic. Ukuze kuthuthelwe uketshezi oluvamile oluvuthayo, insimbi evunguzayo yokushisela kufanele ibe yi-100% yokuhlolwa kwe-SX-ray noma i-ultrasound, esetshenziselwa amanzi, indle, umoya, ukushisisa isitimu kanye nolunye uketshezi olujwayelekile lokudlulisela olunepayipi lensimbi elivunguzayo kufanele libe ngama-X-ray noma amasheke okuhlola ama-ultrasonic ( 20%).

Imiphumela yokuhlolwa kwekhwalithi yepayipi yensimbi Kuvunguza, ipayipi elivunguzayo livame ukuhlukaniswa ngezigaba ezintathu: Okufanelekile, ukusebenza kabusha nokulahlwa. Okufanelekile kusho ikhwalithi nokubukeka kwekhwalithi yangaphakathi ukuze kuhlangatshezwane namazinga noma ukulethwa kobuchwepheshe kanye nezimo zokwamukela ipayipi lensimbi elivunguzayo; rework ibhekisela ikhwalithi kanye ukubukeka engaphakathi izinga akuhambisani ngokugcwele nenqubo yokwamukela kanye strip umzimba, kodwa uvumele ukulungiswa ngemva kokulungiswa kungaba ukuhlangabezana nezindinganiso kanye nezimo ukwamukelwa Kuvunguza ipayipi; imfucuza isho ikhwalithi esezingeni eliphansi kanye nokubukeka kwekhwalithi yangaphakathi yensimbi evunguzayo namanje ayikafiki ezingeni elijwayelekile futhi izimo zokwamukelwa azikuvumeli ukukhanda noma ukusetshenzwa kabusha kamuva.
