Umzi-mveliso wombhobho we-Spiral kufuneka wenziwe phambi kovavanyo lokusebenza koomatshini kunye novavanyo lokucaba, kunye novavanyo lokuvutha, kunye nokuphumeza iimfuno ezisemgangathweni. Indlela yokuhlola umgangatho wombhobho wentsimbi ye-Spiral imi ngolu hlobo lulandelayo:
I-1, ukusuka ebusweni bayo, oko kukuhlola okubonakalayo. Ukuhlolwa okubonakalayo kwamalungu adityanisiweyo yinkqubo elula kodwa indlela yokuvavanya esetyenziswa ngokubanzi yinxalenye ebalulekileyo yovavanyo lwemveliso, iziphene eziphambili kunye nokuphambuka kufumaneka kumphezulu wesayizi weld. Ngokuqhelekileyo ngeso lenyama, kunye nemodeli eqhelekileyo, i-gauge kunye nezixhobo zokuvavanya ezifana neglasi yokukhulisa. Ukuba i-weld surface ineziphene, iziphene ze-weld zinokubakho ngaphakathi.

2, Iindlela zovavanyo lomzimba: indlela yovavanyo lomzimba kukusebenzisa uvavanyo oluthile lomzimba okanye indlela yovavanyo. Okanye ngaphakathi kwesixhobo sokuhlola isiphene, kwaye zisetyenziswa ngokubanzi iindlela ze-NDT. Ukufunyanwa kwempazamo ye-NDT ye-ultrasonic, ukubonwa kwemitha, uvavanyo lokungena, uvavanyo lwemagnethi njalo njalo.

3, Uvavanyo lwamandla eenqanawa zoxinzelelo: iinqanawa zoxinzelelo, ukongeza kuvavanyo lokuqina, kodwa kunye novavanyo lwamandla. Kukho uvavanyo oluqhelekileyo lweemvavanyo ezimbini zehydraulic kunye noxinzelelo lomoya. Banokuvavanywa ekusebenzeni phantsi kweenqanawa zoxinzelelo kunye ne-piping welds compactness. Uvavanyo loxinzelelo lwe-Hydrostatic lunovakalelo ngakumbi kunesantya sovavanyo kwaye, kwangaxeshanye emva kokuba iimveliso zovavanyo zingamoshi unyango lwamanzi, iingxaki zokuhambisa amanzi kwimveliso zisebenza ngokukodwa. Kodwa umngcipheko mkhulu kunovavanyo loxinzelelo lovavanyo. Xa ivavanywa, kufuneka ihambelane namanyathelo okhuseleko afanelekileyo okuthintela iingozi ngexesha lovavanyo.

I-4, Uvavanyo lwe-Compact: i-liquid okanye i-gas storage isitya i-welding, engeyiyo i-weld dense defects, njenge-crack yokungena, ii-pores, i-slag, ukungena okungaphelelanga kwezicubu ezikhululekile kunye nokunye okunjalo, kunokusetyenziswa ukufumana uvavanyo lobuninzi. Iindlela zovavanyo lokuqina zezi: uvavanyo lweparafini, ukuthwala uvavanyo lwamanzi, amanzi aya kuvavanya.

5, Uvavanyo lwe-hydrostatic kufuneka lwenziwe uvavanyo ngalunye lombhobho we-hydrostatic ngaphandle kokuvuza, uvavanyo loxinzelelo loxinzelelo Bala P = 2ST / D apho i-S- hydrostatic test stress test Mpa, uvavanyo loxinzelelo lwe-hydrostatic ngokwemigangatho yentsimbi ehambelanayo ichaza ubuncinci beqondo lesivuno ( I-Q235 yi-235Mpa) i-60% yokhetho. Ixesha labalawuli: D <508 uxinzelelo lovavanyo lokubamba ixesha elingaphantsi kwemizuzwana ye-5; Uxinzelelo lwe-D≥508 lovavanyo olubambe ixesha elingaphantsi kwe-10 imizuzwana ye-4, uvavanyo olungonakaliyo lwentsimbi ye-welding seam, i-strip end weld kunye ne-circumferential joints kufuneka i-X-ray okanye i-ultrasonic inspection. Kuthutho oluqhelekileyo lolwelo oluvuthayo olujikelezayo lwentsimbi ukuya kwi-weld kufuneka lube yi-100% ye-SX-ray okanye uvavanyo lwe-ultrasound, olusetyenziselwa amanzi, ugutyulo, umoya, ukufudumeza umphunga kunye nolunye ulwelo olusasaza ngokubanzi olunombhobho wentsimbi we-spiral kufuneka lube yi-X-reyi okanye iitshekhi zokuhlolwa kwe-ultrasonic ( 20%).

Iziphumo zovavanyo lomgangatho wentsimbi yombhobho ovunguzayo, umbhobho ojikelezayo udla ngokwahlulwa ngokweendidi ezintathu: Ufanelekile, usebenza ngokutsha kunye nelahlwa. Ukufaneleka kuthetha umgangatho kunye nenkangeleko yomgangatho wangaphakathi ukuhlangabezana nemigangatho okanye unikezelo lobugcisa kunye neemeko zokwamkelwa kombhobho wentsimbi ejikelezayo; rework libhekisela umgangatho kunye nenkangeleko umgangatho engaphakathi ayihambelani ngokupheleleyo nemigaqo ukwamkelwa kunye strip umzimba, kodwa ukuvumela ukulungiswa emva kokulungiswa unako ukuhlangabezana nemigangatho kunye neemeko ukwamkelwa spiral umbhobho; inkunkuma ibhekiselele kumgangatho ophantsi kunye nenkangeleko yomgangatho wangaphakathi wentsimbi ejikelezayo ayikafiki kumgangatho kunye neemeko zokwamkelwa azivumeli ukulungiswa okanye ukuphinda kusetyenzwe kamva.
