1. Material preparation: select suitable materials according to the design requirements, such as stainless steel or carbon steel plate. Then cut, bend and other processing, the plate will be made into the required shape and size.
2. Welding: Weld the cut plates to form the main structure of the spiral plate heat exchanger. Welding method can be manual welding or automatic welding, to ensure that the weld seam is solid and good sealing.
3. Assembly: The welded plates are assembled. This includes the installation of import and export piping, support frames, sealing gaskets and so on. The assembly process needs to be carried out in strict accordance with the design requirements to ensure that the connection of the components is tight and no leakage.
4. Cleaning: the assembled spiral plate heat exchanger for cleaning. The purpose of cleaning is to remove welding slag, oil and other impurities generated in the welding process to ensure that the internal channel is smooth and improve the heat transfer effect.
5. Testing: spiral plate heat exchanger for various tests. This includes pressure tests, leakage tests, size checks and so on. Through testing, to ensure that the quality of the spiral plate heat exchanger meets the design requirements, and can operate normally.
6. Packaging: Packaging of the tested spiral plate heat exchanger. Usually use appropriate packaging materials, such as wooden boxes or plastic film, to protect the heat exchanger from damage, and facilitate transportation and storage.
The above is the specific production process of spiral plate heat exchanger, each step needs to be strictly controlled and operated to ensure the stability of product quality and performance.
