Apho iiellipses (...) zivela kule theyibhile, akukho mfuneko, kwaye uhlalutyo lwento akufuneki lumiselwe okanye luxelwe. B Kuvumelekile uku-odola i-T2 kunye ne-T12 kunye nomxholo wesulfure we-0.045 max. C Kungenjalo, endaweni yalomlinganiselo ubuncinane, imathiriyeli iya kuba nobulukhuni obuncinci be-275 HV kwimeko yokuqina, echazwe njenge-austenitizing kunye nokupholisa kwiqondo lobushushu begumbi kodwa ngaphambi kokushushu. Uvavanyo lokuqina luya kwenziwa phakathi kobungqingqwa bemveliso. Uvavanyo lokuqina rhoqo luya kuba ziisampuli ezimbini zemveliso nganye kwindawo yonyango lobushushu kwaye iziphumo zovavanyo lokuqina ziya kuxelwa kwingxelo yovavanyo lwemathiriyeli.

Imfuneko yoVavanyo
Uvavanyo lweHydraustatic:
Umbhobho weNtsimbi kufuneka uVavanywe ngokweHydraulically enye nenye. Uxinzelelo oluphezulu lovavanyo luyi-20 MPa. Ngaphantsi koxinzelelo lovavanyo, ixesha lokuzinzisa kufuneka lingabi ngaphantsi kwe-10 S, kwaye iPipe yensimbi akufanele ivuze. Okanye uVavanyo lweHydraulic lunokuthi lutshintshwe ngoVavanyo lwangoku lwe-Eddy okanye uvavanyo lokuvuza kweMagnetic Flux.
Uvavanyo olungonakaliyo:
Imibhobho efuna uHlolo oluthe kratya kufuneka ihlolwe ngokwe-Ultrasonically nganye nganye. Emva kokuba uThetha-thethwano lufuna imvume yeQela kwaye luchazwe kwiKhontrakthi, olunye uvavanyo olungabhubhisi lunokongezwa.
Uvavanyo lokucaba:
Iityhubhu ezinoMda waNgaphandle oMkhulu kune-22 mm ziyakuBekelwa kuVavanyo lokuNcandwa. Akukho Kulahlwa okubonakalayo, amabala amhlophe, okanye ubumdaka obunokuthi kwenzeke ngexesha lovavanyo lulonke.
Uvavanyo lokuqina:
Ngombhobho wamaBanga P91, P92, P122, kunye neP911, Brinell, Vickers, okanye Rockwell Ukuqina kovavanyo kuya kwenziwa kwiSampulu kwiLoti nganye.
