High Quality Brazed Plate Heat Exchanger Low Price With CE
Description
Plate heat exchanger has a variety of flow path combinations, all of which are realized by different reversing plates and different assembly methods. Flow path combination is divided into single flow, multi flow and mixed flow, should be selected according to the process requirements. In general, the media with temperature difference greater than 1.8 times the logarithmic average temperature difference should adopt multi-flow. The interplate flow rate is 0.3-0.5m /S. If the flow is too small, double or multiple flows should be used.
Parameter
| Gasket material | Temperature range (℃) | Corrosion resistance |
NBR | -20~110 | It has good corrosion resistance to chain hydrocarbon (propane,
butane, etc.), mineral oil, animal and vegetable oil, aliphatic hydrocarbon, ethylene glycol, acid and alkali dilute solution. |
HNBR | -20~165 | It has good corrosion resistance to chain hydrocarbon (propane,
butane, etc.), mineral oil, animal and vegetable oil, aliphatic hydrocarbon, ethylene glycol, acid and alkali dilute solution. |
EPDM | -50~150 | Resistant to dilute acid, alkali and salt corrosion. Suitable for
hot water, saturated steam, glycol, organic acid, sodium hydroxide, ethanol, hexadecane, ester, etc. |
H-EPDM | -20~165 | Resistant to dilute acid, alkali and salt corrosion. Suitable for
hot water, saturated steam, glycol, organic acid, sodium hydroxide, ethanol, hexadecane, ester, etc. |
S-EPDM | -20~130 | Resistant to dilute acid, alkali and salt corrosion. Suitable for
hot water, saturated steam, glycol, organic acid, sodium hydroxide, ethanol, hexadecane, ester, etc. |
Viton | -40~180 | Excellent corrosion resistance. It is suitable for high
concentration inorganic acid-base and polar chemical medium,
mineral oil, silicone oil and silicone resin, animal and vegetable oil, chain hydrocarbon (propane, butane, mineral oil, etc.), hydrocarbon chloride, fuel, non gas resistant substance, etc. |
| Chloroprene rubber(CR) | -50~100 | It is resistant to dilute non oxidizing acid and alkali. |
| Silicon | -65~230 | Corrosion resistant to dilute acid, alkali and brine. |
Compressed fiber(AFM34 SIL-4400) | 260 | Oil, water and vapor (up to 160 ℃), gas, salt solution, fuel, ethanol, organic / inorganic acids, refrigerants, hydrocarbons. |
PTFE | -200~260 | It has excellent corrosion resistance. Except molten metal lithium,
sodium, potassium, chlorine trifluoride, oxygen trichloride at high temperature and liquid fluorine with high flow rate, it can resist all chemical media (including concentrated nitric acid and aqua regia). |
Structural features of plate heat exchanger:
1. The plate group includes a certain number of heat transfer plates, which are determined according to the needs of the heat transfer area.
2. The gasket on the plate ensures that the flow channels are sealed against each other. Gaskets also determine the direction of fluid flow in the heat exchanger.
3. The frame is fastened to the plate with fastening bolts.
4. The interface for the inlet and outlet media is usually on the fixed compression plate of the heat exchanger. In the case of multi-channel, the connection port must be on the fixed compression plate.
5. Adjacent plates form runners for hot and cold media respectively. If the two media have the same number of flow channels, 100% countercurrent flow can be achieved.
