Iivalvu zebhola ezidityanisiweyoukubonelela ngoqhagamshelo oluhlala luhleli nolungenamanzi kwiinkqubo ezibalulekileyo zemibhobho. Ukuqonda umahluko osisiseko phakathi kokuwelda kwe-solvent kunye nokuwelda kwe-thermal kubalulekile ekukhetheni iivalvu ngokufanelekileyo:
| Ipharamitha | Iivalvu zeBhola zeWeld zeSolvent | Iivalvu zeBhola zeWeld ezishushu |
| Indlela yoQhagamshelo | Ukuhlanganiswa kweekhemikhali ze-thermoplastics | Ukunyibilika kwesinyithi (TIG/MIG welding) |
| Izixhobo | I-PVC, i-CPVC, i-PP, i-PVDR | Intsimbi engatyiwayo, intsimbi yekhabhoni |
| Ubushushu Obuphezulu | 140°F (60°C) | 1200°F+ (650°C+) |
| Uvavanyo loxinzelelo | Iklasi ye-150 | Iklasi 150-2500 |
| Izicelo | Ukudluliselwa kweekhemikhali, unyango lwamanzi | Ioyile/igesi, umphunga, imigca yoxinzelelo oluphezulu |
Iintlobo zeValve zeBhola eziWelded ezichazwe
1. Iivalvu zeBhola eziWelded ngokupheleleyo
–Ulwakhiwo: Umzimba we-monolithic ongenazo iiflange/ii-gasket
–IingeneloIsiqinisekiso sokungavuzi nto, ubomi benkonzo obungaphezu kweminyaka engama-30
–Imigangatho: ASME B16.34, API 6D
–Iimeko zokusetyenziswa: Imibhobho engaphantsi komhlaba, usetyenziso lwamanzi angaphantsi komhlaba, izitishi ze-LNG
2. Iivalvu zeBhola eziNcinciweyo
–Uyilo lweHybrid: Umzimba odibeneyo + ibhonethi eboshiweyo
–Ulondolozo: Ukutshintshwa kwesitywino ngaphandle kokusika umbhobho
–Imizi-mveliso: Ukuveliswa kwamandla, ukucutshungulwa kwamayeza
–Uxinzelelo: Iklasi 600-1500
3. Iivalvu zeBhola eziWelded zeNtsimbi engenasici
–Amabanga: 316L, 304, i-duplex, i-super duplex
–Ukumelana nokugqwala: Imelana neekloridi, iiasidi, i-H₂S
–IziqinisekisoI-NACE MR0175 yenkonzo emuncu
–Iindlela zokucoca: 3A ihambelana nokutya/ikhemesti
Izicelo zeShishini ngokohlobo
| Ishishini | Uhlobo lweValve olucetyiswayo | Inzuzo ephambili |
| Ukucubungula iikhemikhali | Iivalvu ze-CPVC ze-weld zesinyibilikisi | Ukumelana ne-sulfuric acid |
| Ioyile kunye neGesi | Iivalvu ze-SS316 ezidityanisiweyo ngokupheleleyo | Isatifikethi se-API 6FA esikhuselekileyo emlilweni |
| Ukufudumeza kweSithili | Iivalvu zentsimbi yekhabhoni ezihlanganisiweyo | Ukumelana noxinzelelo olushushu |
| I-Pharma | Iivalvu zentsimbi engenasici zococeko | Imiphezulu epholishiweyo ngombane |
NSW: Umvelisi weValve yeBhola yeWeld eQinisekisiweyo
