Umbhobho wentsimbi engenamthungo, okwaziwa ngokuba ityhubhu yentsimbi engenamthungo, ngumbhobho omde onomgongxo osetyenziselwa ukuhambisa ulwelo (ulwelo okanye iigesi).
"Ipayipi engenamthungo engenamthungo" kunye "netyhubhu yensimbi engenasici" iphantse itshintshe, nangona ulwahlulo oluncinci lukhona ngokubanzi, ityhubhu ineemfuno zobunjineli ezingqongqo kunombhobho.
UCepheus ngumvelisi ochwepheshile okhethekileyo ekwenzeni imibhobho engenamthungo kubukhulu, obuphakathi, kunye nobukhulu obuncinci.
Imibhobho eyahlukeneyo yentsimbi engenamthungo iveliswa ngeenkcukacha ezipheleleyo kunye nomgangatho ophezulu.
I-Cepheus inezixhobo ezilungileyo kunye nolawulo olupheleleyo lomgangatho, iseka inkqubo yolawulo lomgangatho wale mihla, yazisa itekhnoloji ephucukileyo kumazwe ngamazwe kwaye isebenzisa ubuchule bemveliso behlabathi.
Umbhobho wentsimbi engenamthungo isetyenziswa ngokubanzi kumashishini afana nepetroleum, ishishini lemichiza, oomatshini, amandla ombane, ifayibha yemichiza, ukwenza iphepha, ukuprinta kunye nokudaya, ukutya kunye neenxalenye zepneumatic njl.
Inkampani ibonelelwe ngezixhobo zokuhlola ezipheleleyo kwaye yamkele imigangatho yobuchwephesha yeemveliso ezinje: umbhobho ongenamthungo wokuthuthwa kwamanzi, umbhobho ongenamthungo wokwakha, ongenamthungo kwibhoyila kunye nomtshintshisi wobushushu.
Ubukhulu obungaphandle be-stainless stainless esiyivelisayo ukusuka kwi-4.0mm ukuya kwi-1219mm. Ubukhulu bodonga yi-0.5mm ukuya kwi-100mm. Kwintsimbi, sizimisele.

| Ubunzima obuthiyori(kg/m) | Ubunzima / imitha = (OD-WT) * WT * 0.02507ZombiniODkwayeWTkwi mm. |
Phawula:
I-OD yidayamitha yangaphandle echaziweyo.
I-WT bubukhulu bodonga obuxeliweyo
Imibhobho yentsimbi engatyiwayo iya kucholwa simahla. Xa i-annealing eqaqambileyo isetyenzisiweyo, i-pickling ayiyimfuneko.
