Cov pob valve weldedmuab kev sib txuas ruaj khov, tsis xau hauv cov kav dej tseem ceeb. Kev nkag siab txog qhov sib txawv ntawm kev vuam cov kuab tshuaj thiab kev vuam thermal yog qhov tseem ceeb rau kev xaiv lub valve kom raug:
| Cov Qauv | Cov Khoom Siv Solvent Weld Pob Valves | Thermal Weld Pob Valves |
| Txoj Kev Sib Txuas | Kev sib xyaw ua ke ntawm cov thermoplastics | Hlau melting (TIG / MIG vuam) |
| Cov ntaub ntawv | PVC, CPVC, PP, PVDR | Hlau tsis xeb, hlau carbon |
| Kub Tshaj Plaws | 140°F (60°C) | 1200°F+ (650°C+) |
| Kev Ntsuas Siab | Chav Kawm 150 | Chav Kawm 150-2500 |
| Cov ntawv thov | Kev hloov tshuaj lom neeg, kev kho dej | Roj/gas, pa dej, cov kav dej siab |
