Ubude:
Ubude obuqhelekileyo beepayipi zentsimbi yi-4 000 mm ~ 12 000 mm. Emva kokubonisana phakathi komthengisi kunye nomthengi, kunye nokugcwalisa isivumelwano, ingaziswa iipayipi zentsimbi ezinobude obungaphezulu kwe-12 000 mm okanye ezimfutshane kune-1 000 mm kodwa ezingaphantsi kwe-3 000 mm; ubude obufutshane Inani leepayipi zentsimbi ezingaphantsi kwe-4,000 mm kodwa ezingaphantsi kwe-3,000 mm aziyi kudlula i-5% yenani lilonke leepayipi zentsimbi ezihanjiswayo.
Ubunzima bokuhanjiswa:
Xa umbhobho wentsimbi uthunyelwa ngokwesixa-mali sangaphandle esiqhelekileyo kunye nobukhulu bodonga oluqhelekileyo okanye ububanzi bangaphakathi kunye nobukhulu bodonga oluqhelekileyo, umbhobho wentsimbi uthunyelwa ngokwesixa-mali sokwenyani. Ungathunyelwa ngokwesixa-mali sethiyori.
Xa umbhobho wentsimbi uthunyelwa ngokwesixa-mali sangaphandle esiqhelekileyo kunye nobukhulu bodonga obuncinci, umbhobho wentsimbi uthunyelwa ngokwesixa-mali sokwenyani; amaqela okubonelela kunye neemfuno ayaxoxisana. Kwaye kubonisiwe kwisivumelwano. Umbhobho wentsimbi ungathunyelwa ngokwesixa-mali sokwenyani.
Ukunyamezelana kobunzima:
Ngokweemfuno zomthengi, emva kokubonisana phakathi komthengisi nomthengi, nakwisivumelwano, ukuphambuka phakathi kobunzima bokwenyani kunye nobunzima bethiyori yombhobho wentsimbi yokuhambisa kuya kuhlangabezana neemfuno ezilandelayo:
a) Umbhobho wentsimbi enye: ± 10%;
b) Ibhetshi nganye yemibhobho yentsimbi enobukhulu obuncinci be-10 t: ± 7.5%.
Uvavanyo lwe-Hydraustatic:
Umbhobho wentsimbi kufuneka uvavanywe ngamanzi nganye nganye. Uxinzelelo oluphezulu lovavanyo yi-20 MPa. Phantsi koxinzelelo lovavanyo, ixesha lokuzinzisa kufuneka lingabi ngaphantsi kwe-10 s, kwaye umbhobho wentsimbi akufuneki uvuze.
Emva kokuba umsebenzisi evumile, uvavanyo lwe-hydraulic lunokutshintshwa luvavanyo lwe-eddy current okanye uvavanyo lokuvuza kwe-magnetic flux.
Uvavanyo olungonakalisiyo:
Imibhobho efuna uhlolo olongezelelekileyo kufuneka ihlolwe nge-ultrasound nganye nganye. Emva kokuba ingxoxo ifuna imvume yeqela kwaye ichazwe kwisivumelwano, olunye uvavanyo olungonakalisiyo lunokongezwa.
Uvavanyo lokuTyatya:
Iityhubhu ezinobubanzi obungaphandle obungaphezulu kwama-22 mm ziya kuvavanywa ngokuthamba. Akukho kususwa okubonakalayo, amabala amhlophe, okanye ukungcola okufuneka kwenzeke ngexesha lonke lovavanyo.
Uvavanyo lokuvutha:
Ngokweemfuno zomthengi kwaye zichazwe kwisivumelwano, umbhobho wentsimbi onobubanzi obungaphandle obuyi-≤76mm kunye nobukhulu bodonga obuyi-≤8mm ungenziwa uvavanyo lokutshaya. Olu vavanyo lwenziwe kubushushu begumbi nge-taper engama-60 °. Emva kokutshaya, izinga lokutshaya kobubanzi obungaphandle kufuneka lihlangabezane neemfuno zetafile elandelayo, kwaye izixhobo zovavanyo akufuneki zibonise imifantu okanye ukukrazuka.
