Caidéil Ghléasra Díshalaithe: 2507 vs . 904 l Friotaíocht Creimthe Creimthe

 

Cén fáth a bhfuil Super Duplex 2507 chun tosaigh ar chaidéil ardbhrú RO?
2507 provides PREN >42 and 550 MPa yield strength for 80-bar service. Its dual-phase structure withstands 45,000 ppm chlorides at 8 m/s flow velocity. Cavitation resistance is 3x higher than 316L due to 300 HV bulk hardness. Cost is 40% lower than Cóimhiotail Nicil .

 

Nuair a shonraítear 904L le haghaidh inmheánacha téitheoir sáile?
Sáraíonn 904L i gcriosanna sáile stagnant le<0.5 mm/year corrosion rate. High nickel (25%) prevents chloride stress cracking during thermal shocks. Molybdenum (4.5%) resists pitting under silica scale deposits. Required for sulfuric acid cleaning cycles.

 

Teorainneacha treoluas sreafa criticiúil?
Minimum 1.8 m/s prevents particulate settlement. Maximum 6.5 m/s for 2507 and 8 m/s for 904L before erosion acceleration. Velocity >10 m/s is cúis le damáiste cavitation beag beann ar chóimhiotal .
