The main technical parameters of spiral plate heat exchanger
日期：2022/9/7
Spiral plate is a heat exchanger whose heat transfer elementis composed of spiral plate, it is highly efficient heat exchanger equipment, and it is apply to steam - steam, steam - liquid, liquid – liquid, transfers for liquid. It is suitable for chemical, oil, solvents, medicine, food, light industry, textile, metallurgy, steel rolling, scorch and other industries.
1. Nominal pressure ofspiral plate heat exchangeris defined as0.6,1,1.6,2.5Mpa（that isthe original 6, 10, 16, 25kg/cm）（refers to the maximum working pressure of the single-channel）The test pressure is 1.25 times the working pressure.Straightening machine,http://www.wxlbjz.com/
2. The part of materialwhenspiral plate heat exchanger touches with media, carbon steel is Q235A、Q235B, stainless steel is SUS321、SUS304、316L.And other materials can be selected according to user requirements.CNC punch processing:http://www.wx-unt.com/
3. Permissible working temperature:Carbon steel is -20-3500C,stainless steel is-20-3500C.
4. The selection of equipment, through proper process calculation to make liquid within the channel reaches turbulent state（General liquid velocity≥0.5m/s；gas velocity≥10m/s）
5. The equipment can be placed horizontally or vertically, but can only stand up for the steam condensation.
6. For caustic soda industry it must carry out the overall heat treatment, in order to eliminate stress
When the difference of the flow value on both sides of the channel is large, it can be used unequal interval channel to optimize the process design.
