The flange interface of the generally produced plate heat exchanger is determined according to the customer's needs and the actual conditions of the working conditions. The following Xiaobian introduces the form of the flange interface of the plate heat exchanger, and friends who want to know follow the introduction of Xiaobian to see it. According to the position of the inlet and outlet flanges, there are four types: single side, single side, double flow, and single side. 1. Single side: It is a common type and standard type of plate heat exchanger, which is usually used for water-water and steam-water heat exchange; the four holes of the interface are on one plane of the clamping plate, and are positioned according to the regulations. The dimensions are distributed over the four corners. 2. Respectively single side: The interface form is determined according to the position of the pipeline. The position of such interfaces is longitudinal on the left and right sides respectively. 3. Double process: usually used for heat exchange oil medium. Due to the high density and high concentration of oil, the heat transfer coefficient is low during heat exchange. The heat transfer coefficient becomes larger to complete the heat exchange, and the positions of the flanges are opposite on the upper sides of the left and right ends. 4, single sides: refers to the four flange holes on the left and right sides, respectively on the upper end of the left and the lower end of the right. The above is the content of the plate heat exchanger introduced to everyone, I hope to bring you some help.
