The fully welded plate heat exchangers provide efficient heat transfer with compact footprint, for demanding process applications. They are designed for high pressure and high temperature, providing security when dealing with dangerous fluids. The heat exchangers are used in a wide range of cooling, heating, evaporation and condensing duties .
Prodcut feature
1. High Heat Transfer efficiency
2. Prevent High Temperature/Pressure
3. Simple Operation
Plate material
Material of plate: SS304 、SS316L...
Thickness of plate: 0.8mm- 1.2mm
Application industry
Fully welded PHE is suitable for chemical, fertilizer, pharmaceutical, metallurgy, machinery. They are used for heating, condensation, cooling and heat recovery and other processes.
Production process
1. When stainless steel raw materials enter the factory, first use a stainless steel quick test solution to detect whether it is 304 or 316L stainless steel through electrolysis. Use a micrometer to detect the thickness of the material. At the same time, check whether the data on the raw material material certificate is consistent, and then cut to size.
2. The plate enters the abrasive tool to be pressed. After the press is formed, the press-formed plate is sampled and tested with the penetrant according to the proportion to detect whether there are pinholes.
4. Cold side welding, press the pipe, and check the drawing size required by the customer at the same time. After the cold side welding is completed, perform a cold side pressure test for 20-25 minutes to check whether the welds are melted. Whether there is internal leakage on the side plate or whether there is water leakage in the welding seam.
5. Weld the hot side, press the tube, and check the size of the drawing required by the customer. After the hot side welding is completed, carry out a unilateral pressure test on the hot side. The pressure holding time is 20-25 minutes. Whether there is internal leakage in the side plate or whether there is water leakage in the welding seam.
6. The frame board is cut, sandblasted and painted.
7. Clean and polish the welding part of the nozzle, spray the silver powder paint on the fully welded core body, measure whether all the dimensions meet the customer's drawing dimensions, and carry out assembly and general inspection.
8. Perform the last inspection of the equipment to see if the spray paint is intact and smooth, whether the nozzles have been polished and cleaned, and whether the overall size meets the customer's drawing requirements.
