In industriae applications, arbitrium de valvae materiae directe afficit salutem, efficientiam et sumptus de systematis. Upvc (unplasticized polyvinyl chloride) et CPVC (chlorinated polyvinyl chloride) sunt duo communi plastic valvae Materias, quae sequuntur Laudate (German Industrial) and Ansi (American National Latin) Specifications respective. Et sequenti analysis peragitur ex tribus facies: core euismod, applicationem missionibus et lectio consilia.
UPVC / CPVC Flacc Diaphragma CYMBALON
I. Core perficientur collatio
| Proprium | Upvc valvae | CPVC CYMBALON |
| Temperature resistentia range | -10 ° C ad LX ° C (brevi-term LXX ° F) | -10 ° C XCIII ° C (brevi-term CX ° C) |
| Chemical resistentia | Repugnant acida alkalis et sal solutiones; Non repugnant fortis oxidizing agentibus | Repugnant fortis acida, fortis alkalis, organicum solvents; fortior oxidatio resistentia |
| Mechanica vires | Inferior, idoneam humilis-pressura systems (Pn10 / Class150) | Superiore, potest sustinere medium-princeps pressura (Pn16 / Class300) |
| Flamma retardancy | Auto-exstinguunt, exstinguit statim cum remota a flamma | Auto-exstinguunt, non facile regnavit postquam ab flamma |
| Cost | Inferior | Altior (materiam pretium crescit per circiter XXX% -50%) |
II. Typical application missionibus
Applicabiles missionibus ad upvc valvulae
Aqua curatio systems: ut bibens aqua translationem, purgamentorum curatio (PH 2-12).
Chemical processibus: Media ut Hydrochloric Acidum, sulphuric acidum (concentration Minimum-temperatus industria, ut frigus repono pipelines, refrigerationem aqua circulationem (temperatus Applicabiles missionibus ad CPVC Valvulae
High-temperatus chemicals: ut calidum alkali solution (LXXX ° C), organicum solvents (ut methanolum et toluene).
Power Industry: Boiler Pasce aqua, desalted aqua ratio (magna temperatus fluctus).
Semiconductor vestibulum, ultrapure aqua ratio (requirit princeps mundities et temperatus resistentia).
III. Electio Strategy et consilium ligno
Temperatus prioritate
Si medium temperatus est> LX ° C: Select CPVC Valvulae (ut calor exchanger bypass, summus temperatus Purgato ratio).
Si temperatus est ≤60 ° C: Upvc valvulae sat (ut normalis temperatus adipiscing piscinam asperis et exitus).
Media corrosiveness
Fortis oxidizing media (ut sodium hypochlorite, conuenerunt nitric acidum): CPVC est melius (postulo ut confirmet specifica intentratione et temperatus).
Ordinarius acida et alkalis (ut diluto sulphuric acidum et sodium hydroxide) UPVC est plus cost-effective.
Pressura campester
High-pressura ratio (> Pn10 / Class150) CPVC Valvulae (ut Vapor Tracandas Pipelines).
Humilis-pressura ratio (≤pn10 / Class150): UPVC Valvulae (ut gravitatis flow pipelines).
Custus et Vita
Budget-sensitivo projects: upvc valvulae (humilis initial sumptus, sed crebris replacement).
Long-term operatio projects: CPVC Valvulae (Vita Extended by L% -100%, humilis sustentacionem cost).
Obsequium
EU Projects: Laudate Latin Upvc / CPVC Valvulae (CE Certified).
North American Projects: Ansi Latin CPVC Valvulae (obsequia cum asme b16.5 cubits).
IV. Key considerations
Installation Specifications: CPVC valvulae ut custodiri a recta solis (ultraviolet radios accelerate senescit) et commendatur adhibere sunscreen coating.
Temperature inpulsa: CPVC Valvulae Opus ad instructum cum expansionem articulis in alterna calidum et frigus environments ne scelerisque accentus fregisset.
Compatibility: UPVC et CPVC Pipes non sit directe Welded et coniungi per Flannges vel Unionibus.
