H17 Gasket Parameter
| Rubber Type | NBR | EPDM | VITON/FKM | HNBR |
| Application Temperature | -20°C- +130°C | -50°C-+150°C | -30°C-+251°C | -15°C- +160°C |
| Fluid Media | Water Sea water Mineral oil Salt brine | Hot water Steam Acid Alkali | High temperature resistance Strong oxidants Oil Acid and alkali | High temperature mineral oil and water |
| Feature | Easier to replace than the traditional gasket, high pressure, high
temperature, longer life, should not be leaked |
| Material of Gasket | Operating Temperature(℃) | Suited Liquid kinds |
| NBR | -15 to +135 | Water,sea water etc |
| EPDM | -25 to +180 | Hot water,steam etc |
| FPM/VITON | -55 to +230 | Acid,Caustic,Fluid |
| HNBR | 0 to +160 | Concentrated acid etc
|
Gasket failures are generally a result of:
• old age
• excessive exposure to ozone
• high operating temperature – above the temp. limit of the
material
• exposure to pressure surges
• chemical attack
• physical damage, resulting from incorrect assembly work, or
damage
• resulting from a misaligned plate (check the hanging system at
the top of the plate for
distortion).
Plate Heat Exchanger Reasons of Performance Degradation
Decrease in performance is generally a result of:
• plate surfaces require cleaning or de-scaling
• pumps or associated controls have failed
• plate channels blocked
• liquid flows not as per design specification
• associated chiller / cooling tower / boiler under sized or dirty
• cooling water temperature to the exchanger is higher than the
design
• heating media temperature to the exchanger is lower than the
design
• steam flow not sufficient – control valve malfunction
• steam trap broken or jammed – unit becomes filled with condensate
• plate package has been assembled incorrectly
• unit is running in co-current flow, instead of counter current –
check with contract
drawing and alter pipe work if necessary. Check direction of pump
flows.
• air lock has developed in the plate package or pipe work
