Plate heat exchanger framework is composed of fixed and moveable plates (including baffle, the intermediate plate), upper and lower guiding bars, columns, tightening bolts, anchors, etc.
Note: fixed and moveable plates (including baffle, the intermediate plate) can be coated by 0Cr18Ni9, 0Cr17Ni12M02.
Small plate exchanger: Using round steel. Commonly used 35, 45 or stainless steel 304
Large plate exchanger: Using the I-beam, H-beam. Commonly used Q235, 35, and stainless steel 304.
column: Using the U-section steel, I-beam, H-beam. Commonly used Q235, 35, and stainless steel 304.
anchor: Using Q235, 35, stainless steel 304
When you select materials, it is necessary to consider their working conditions: for example using stainless steel materials on food machinery. Choosing the container plate, the intensity is higher than carbon steel, but the price will be higher. Choosing alloy steel/quality carbon steel, the intensity is higher than that of carbon steel, but need a higher price and longer delivery time. The intensity of stainless steel is lower than carbon steel. Please take into consideration the influences of various factors.
