The plates we're working on are made of carbon steel plates with thicknesses of 90mm and 108mm. There're 80 sets of pressure plates and fixed frames in this order. The machining plates are for the manufacturing of plate heat exchangers. The fabrication process of the pressure plates and fixed frames involves flame cutting, machining (drilling, milling), surface treatment, etc.
A plate heat exchanger is typically composed of a stack of thin metal plates that are corrugated and welded together. The plates are made of materials such as stainless steel, titanium, or other alloys that are resistant to corrosion and can withstand high temperatures and pressures. Plate heat exchangers are commonly used in HVAC systems, refrigeration, food and beverage processing, and other industrial applications. They are preferred over other types of heat exchangers for their high efficiency, compact size, and ease of maintenance.
The pressure plate and fixed frame are two important components of a plate heat exchanger. Here is an overview of each component:
Pressure Plate: The pressure plate is a movable plate that is placed on top of the plates in the heat exchanger. It is typically held in place by a series of bolts or clamps and is used to apply pressure to the plates and gaskets to create a tight seal. The pressure plate is designed to exert a specific amount of force on the plates, which is necessary to maintain the proper flow rate and prevent fluid leakage. The pressure plate is often made of metal and may be coated with a material that improves its corrosion resistance and durability.
Fixed Frame: The fixed frame is a stationary component of the heat exchanger that provides support and stability for the plates and gaskets. It is typically made of metal, and may be welded or bolted to other components of the heat exchanger. The fixed frame is designed to withstand the pressure and temperature of the fluids being exchanged and may be coated with a material that improves its corrosion resistance and durability.
Together, the pressure plate and fixed frame create a strong and stable structure that holds the plates and gaskets in place and provides the necessary pressure to create a tight seal. The design and construction of these components are critical to the performance and efficiency of the heat exchanger and must be carefully engineered to ensure that the heat exchanger operates safely and reliably over its intended lifespan.
Openex specializes in fabricating custom industrial heat exchangers for effective and precise temperature regulation, including the heating and cooling of liquids and gasses. We manufacture a wide variety of industrial heat exchanger types, each of which is best suited for different applications, purposes, and industries.
