774 As the service life of the plate heat exchanger becomes longer, leakage is a situation that may occur at any time. Investigate the reasons, most of the reasons are the plate heat exchanger gasket problems, such as gasket misalignment, aging, corrosion and so on. So how do we choose products before replacing the gasket of the plate heat exchanger? Here are some elements to consider when purchasing plate heat exchanger gaskets. 1. Brand model First of all, we must be able to provide the original plate heat exchanger brand model, this is to ensure that the purchased rubber pad will not go wrong. If you know the brand model, you can find the manufacturer according to the model brand. 2. Working medium After we have determined the model, we also need to clarify the working medium flowing through our system. Because different media should choose the corresponding gasket material. For example, if you use steam, choose EPDM (Ethylene Propylene Diene propylene) material, and if you use oily medium, choose NBR (Ding Qing) material. In addition, if it is a high-temperature oil, the temperature is>120℃ and <150℃, you can choose HNBR (hydrogenated nitrile) material. 3. Center size This is for if you don't know the brand model, we can also provide the manufacturer with the horizontal and vertical center distance size of the plate heat exchanger gasket. Generally, as long as the center distance size is determined, the rubber pad we buy is of this model. The above are the few elements that need to be considered when purchasing plate heat exchanger gaskets, hoping to help users choose products better.
