Imfuneko yoVavanyo

Uvavanyo lwe-hydraulic
Uvavanyo lwe-hydraulic luya kwenziwa kwimibhobho yentsimbi nganye nganye. Uxinzelelo oluphezulu lovavanyo luyi-20 MPa. Ngaphantsi koxinzelelo lovavanyo, ixesha lokuzinza aliyi kuba ngaphantsi kwe-10 s, kwaye ukuvuza kombhobho wensimbi akuvumelekanga.
Uvavanyo lokucaba
Uvavanyo lwe-flattening luya kuqhutywa kumbhobho wentsimbi kunye nobubanzi obungaphandle ngaphezu kwe-22 mm
Uvavanyo lomlilo
Umgangatho ophezulu we-carbon structural steel kunye nemibhobho yentsimbi (ekwazi ukumelana nobushushu) kunye nobubanzi obungaphandle obungekho ngaphezu kwe-76 mm kunye nobukhulu bodonga obungekho ngaphezu kwe-8 mm buya kuxhomekeka kuvavanyo olwandisiweyo. Uvavanyo lokuvutha luya kwenziwa kwiqondo lokushisa. Umyinge wangaphandle wokugqabhuka kwesampulu emva kokuba i-taper ye-core core i-60% ye-flaring iya kuhlangabezana neemfuno zetheyibhile 7. Akukho kuphazamiseka okanye ukuqhekeka kuvunyelwe kwisampuli emva kokuvutha. Ngokweemfuno zomfaki-sicelo kwaye kuphawulwe kwikhontrakthi, i-alloy structural steel ingasetyenziselwa ukwandisa uvavanyo.
Itesta engonakalisiyo
Imibhobho yensimbi iya kuba phantsi kokufumanisa impazamo ye-ultrasonic nganye ngokuhambelana namalungiselelo e-GB / T 5777-2008. Ngokweemfuno zomfaki-sicelo, ezinye iimvavanyo ezingonakalisi zingongezwa emva kokuxoxisana phakathi komthengisi kunye nomceli kwaye ziboniswe kwisivumelwano.
Uvavanyo lwe-Intergranular Corrosion
Uvavanyo lwe-Intergranular corrosion luya kuqhutywa kumbhobho wentsimbi ongenasici (ukumelana nobushushu). Indlela yokuvavanya iya kuhambelana namalungiselelo endlela yaseTshayina E kwi-GB / T 4334-2008, kwaye ukuthambekela kwe-intergranular corrosion akuvumelekanga emva kovavanyo.
Emva kothethathethwano phakathi komthengisi kunye nomenzi, kwaye kuphawulwe kwikhontrakthi, umfaki-sicelo unokubeka ezinye iindlela zovavanyo lomhlwa.
