Unyango lwangaphambili lwemibhobho yentsimbi yomthungo othe tye: uvavanyo olungenakonakala ngaphakathi kwee-welds. Ekubeni umbhobho ngumbhobho wensimbi omkhulu kakhulu kwiprojekthi yokubonelela ngamanzi, ngokukodwa umbhobho wensimbi kunye nobukhulu be-t = 30mm isetyenziswe njengebhuloho yombhobho. Kufuneka imelane noxinzelelo lwangaphakathi lwangaphakathi kunye nomzuzu wokugoba owenziwe ngumzimba ofileyo wombhobho wensimbi kunye nomzimba wamanzi, ngoko ke iimfuno ze-welding ziphezulu kakhulu. Kwimibhobho yentsimbi enobubanzi obukhulu obuyi-t = 30mm esetyenziswa kwiibhulorho zemibhobho, i-longitudinal seams kunye ne-circumferential seams zombini i-Class I welds, ifuna i-100% yokuhlolwa kwefilimu ye-X-ray kunye ne-100% yokuhlola i-wave flaw; ngelixa kwimibhobho yentsimbi engcwatywe ubukhulu be-t = 24mm, i-longitudinal seams ye-Class I welding, kunye ne-20% yokuhlolwa kwefilimu ye-X-ray kunye nokuhlolwa kwe-50% yokukhangela i-wave flaw.

Ukusetyenziswa kwemibhobho edityanisiweyo ethe tye: Zininzi iintlobo zemibhobho edityanisiweyo ethe tye, ngokokusetyenziswa: imibhobho edityanisiweyo ngokubanzi, imibhobho edityanisiweyo ngeoksijini, imibhobho edityanisiweyo, imibhobho yocingo, imibhobho eqengqelekayo, imibhobho edityanisiweyo yemetric, imibhobho yemoto, inzulu. imibhobho yokumpompa kakuhle, imibhobho yesiguquli, imibhobho edityanisiweyo yombane enemilo eyodwa, kunye nemibhobho edityanisiweyo yombane edityanisiweyo.

Imibhobho edityanisiweyo ngokubanzi: Imibhobho edityanisiweyo ngokubanzi isetyenziselwa ukuthutha ulwelo olunoxinzelelo oluphantsi. Yenziwe nge-Q235A, L245, kunye ne-Q235B yentsimbi.
Imibhobho yentsimbi: Kukugquma umphezulu wombhobho omnyama nge-zinc. Yahlulwe ibe shushu kwaye iyabanda. I-zinc layer eshushu ingqindilili, kwaye ixabiso elibandayo liphantsi.
Imibhobho edityanisiweyo evuthelwa ngeoksijini: Ngokuqhelekileyo, yimibhobho yentsimbi edityanisiweyo enobubanzi obuncinci, edla ngokusetyenziselwa ukwenza intsimbi ukuvuthela ioksijini.
Iingcingo zocingo: Ziyimibhobho yezakhiwo zokusasaza, eziyimibhobho yentsimbi yentsimbi yekhabhoni eqhelekileyo.
Imibhobho edityanisiweyo yombane ecekethekileyo: Yimibhobho enobubanzi obuncinci esetyenziselwa ifenitshala kunye nezibane.
Imibhobho eqengqelekayo: Imibhobho yentsimbi edityanisiweyo yombane kumhambisi webhanti ifuna i-ovality.
Imibhobho yokuguqula: Yimibhobho yentsimbi yekhabhoni eqhelekileyo. Isetyenziselwa ukwenza iityhubhu zokupholisa ze-transformer kunye nezinye izitshintshi zobushushu.
