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.
Maximum volume:5000m3 /h; Maximum design pressure:25bar
Maximum temperature:150 celsius degree; Minimum difference in temperature:0.5-1celsius degree
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
We have hundreds of types of plate and gasket for your choice, with the most complete range, perfect quality and irresistible prices.

1. Efficient heat transfer
Gasketed plate-and-frame heat exchangers (GPHEs) provide efficient heat transfer in compact equipment with a small footprint - much smaller and more efficient than shell-and-tube heat exchangers.
Plate heat exchangers are designed to optimize heat transfer, because the corrugated plates provide by far the greatest surface area through which the heat can be drawn from one gas or liquid to the other.The units also have a flexible design and are easy to service and maintain.
2. Types of gasketed plate heat exchangers
Industrial -extremely versatile range of heat exchangers for use in all types of industries
Industrial semi-welded -used in refrigeration when gaskets are not suitable for one of the media and when higher design pressures are needed
WideGap -used for applications involving fibrous liquids, highly viscous fluids, and fluids containing coarse particles
evaporators-tailor-made, rising film plate surface evaporator
condensers -a compact, plate surface vacuum condenser
Material available for 0.5 & 0.6mm 304SS, 316SS, Titanium, ASMO254, Hastelloy C-276, Nickel Ni201, 904L
