Relying on application practices, HFM Fully Welded Plate Heat Exchangers are widely applied in oil and gas industry, refinery applications, pharmaceutical industry, chemical/petrochemical industry, automotive, pulp and paper industry and steel industry. The Semi-welded Plate Heat Exchanger is particularly offered for heating and cooling of aggressive media. Two corrugated plates are positioned back to back and welded together as "cassette" by laser, along the sealing groove designed for the gasket of the semi welded PHE. The semi-welded plate for PHE is specially offered for aggressive media. Generally, two pieces of PHE stainless steel plates are welded back to back by laser along the sealing groove for the gasket to form the plate cassette. Each cassette is sealed with a gasket. The refrigerant flows from one cassette to the other, contacting with only two of the four ring gaskets at the inlet and the outlet.What are the advantages of Semi-Welded Plate Heat Exchanger?1. Wide temperature range from -38 to 2002. Maximum design pressure up to 30 bar3. Rigid mechanical construction4. Outstanding leak-proof for high safety5. Capacity in handling aggressive media6. Adjustable size7. Compact structure and small installation space
The semi welded plate heat exchanger is composed of a pair of plates, and each of the two plates is laser welded to form a pair of plates. It is sandwiched between the fixed pressing plate and the movable pressing plate in a superimposed manner Product introduction Semi welded plate heat exchanger The semi welded plate heat exchanger is composed of a pair of plates, and each of the two plates is laser welded to form a pair of plates. It is sandwiched between the fixed pressing plate and the movable pressing plate in a superimposed manner. The mesh contacts are formed between adjacentplates and supported by each other, and the rigidity of the plates is remarkably enhanced. Our semi welded plate heat exchanger adopts advanced laser welding technology, which has the advantages of small welding deformation, small residual stress and high quality.Qingdao Ruipute has advanced welding technology, especially for the first time to achieve the welding technology of special materials such as titanium, we are at the domestic leading level in developing and manufacturing semi-welded titanium plate heat exchange equipment. The cavity of the pair of plates forms a pass of a medium; the two pairs of plates are sealed by a sealing gasket which is resistant to corrosion, high temperature and high pressure, and constitutes another medium pass; the two mediums flow evenly in a countercurrent way in the adjacent channels to complete the sufficient heat exchange process. This structure ensures the stability of the welded plate pairs, providing easy maintenance of each pair of plates. It has the characteristics of high safety, high heat transfer efficiency, long service life and easy maintenance. It is suitable for cooling and chemical treatment. It is the ideal alternative equipment to shell and tube heat exchanger and all welded plate heat exchanger.Especially suitable for evaporation and condensation of ammonia coolants,as well as chemical treatment of corrosive liquids.

Principle A plate and frame heat exchanger as known as gasketed plate heat exchanger is a high efficiency heat exchanger that assembled from metal sheets with corrugated pattern and different kind of gaskets. Plate heat exchangers are the ideal equipment for heat exchange between liquid-liquid and liquid-vapor.In the case of the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, but the floor space is one-third of the tube heat exchanger, and the heat recovery rate can be as high as 90% or more. Maximum volume: 5000m3 /h;Maximum design pressure: 25bar Maximum temperature: 200 celsius degree; Minimum difference in temperature: 0.5-1 celsius degree Nozzle diameter: DN15~DN500;Plate thickness: 0.4mm - 1.2mm Gasket material:NBR, EPDM, HNBR, HT-NBR, HEPDM, CR,VITON/FKM Fixed and movable plate material: Carbon Steel, Stainless Steel, and others on request. Plate material:AISI304, AISI316, AISI316L, Titanium,Ti-Pa,Hastelloy C276,254SMO,Nickel, AISI904L. Plate heat exchanger High heat transfer coefficient The design of the plate corrugation is aimed at the high thermal conductivity. The special flow path are formed by the plate corrugation causing strong disturbance flow at a very low flow rate, which is called turbulent flow. And the disturbance flow can be self-cleaning to prevent fouling and thus the heat transfer efficiency is high. Plate heat exchanger Large logarithmic temperature difference The temperature difference at the end is small, and the plate heat exchanger is mostly a cocurrent or countercurrent type of flow. In addition,there's no bypass flow. Plate heat exchanger Small footprint and easy maintenance The plate heat exchanger has a compact structure, and the heat exchange area per unit volume is 2-5 times that of the shell-and-tube type, and the floor area of the plate heat exchanger is about 1/2-1/3 of the shell - tube heat exchanger when achieving same heat exchange capacity .
Product principle The plate and shell heat exchanger adopts a circular corrugated heat exchanger plate that welded into a heat exchanger lathed bundle and combined with the structure of the pressure vessel shell. It also has a high heat transfer efficiency,compact structure and resistant to high temperature & pressure like shell tube heat exchanger. The plate and shell heat is durable under high temperature & pressure,large temperature difference and thermal shock, which is in a leading position in the industry.
