In order to fix the heat exchange tubes, a fixed frame is installed around the heat exchanger. According to the distribution position, the frame can be divided into upper and lower cover plates and side plates on both sides. In some specific places, in order to facilitate the overall fixation, it is necessary to add another plate on both sides; due to the need for effective heat exchange, we usually use seamless steel tubes with an outer diameter of 18, because the outer diameter is small and the internal space is small. The heat transfer speed is fast and the heat transfer efficiency is high.
The fins are 0.2~0.3mm thick carbon steel fins or galvanized fins, which are distributed on the surface of the mother tube by mechanical winding, and then fixed by welding to prevent the fins from loosening and falling off; to ensure the fluidity of the heat exchange tube, replace The heat pipe and the heat exchange tube are connected by a 180-degree elbow. The material selection of the elbow is the same as that of the mother tube, and the welding is convenient. Welding should ensure the continuity and smoothness of the elbow and the connecting pipe to make its internal flow performance better;
The heat exchanger interface is mainly customized according to the needs of the scene. For example, if the customer needs to use the flange on site, then at the factory, we will use the national standard flange interface for the customer to install later. It can accelerate the efficiency; as the working medium mother tube of the heat exchanger, the mother tube must meet the requirements of the overall design, otherwise the overall heat exchange performance will not meet the requirements, and needs to be measured by the system design software.
Gas pipelines, if the customer provides drawings and requirements, we can customize according to the customer's requirements to ensure the on-site replacement of gas pipeline requirements and design requirements, if the customer provides drawings and requirements, we can customize according to the customer's requirements to ensure the on-site replacement Requirements and design requirements.
