The key advantage of this water cap is its 316L stainless steel material, which offers superior corrosion resistance compared to 304 stainless steel, effectively withstanding chloride ion erosion in seawater and brackish water environments, solving the problem of rapid corrosion common in ordinary water caps used in marine applications. The integrated wedge wire structure, manufactured through precision welding, eliminates gaps between components, ensuring it can withstand a maximum working pressure of 4.0 MPa without deformation or leakage. The 0.15mm wedge wire gap precisely intercepts fine filter particles while maintaining high flow rates, reducing energy consumption caused by excessive flow resistance. Additionally, its smooth surface prevents scale accumulation, extending service life and reducing maintenance frequency.
The water cap is constructed from 2.0mm-thick 316L stainless steel, with wedge wires of 1.2mm diameter and a precise gap of 0.15mm, ensuring effective interception of fine filter materials. Its overall height is 80mm, diameter is 50mm, and it features an M20 external threaded connection for secure installation in high-pressure equipment. The maximum working pressure reaches 4.0 MPa, adapting to the high-pressure requirements of RO systems and seawater desalination plants. The temperature resistance range is -20°C to 150°C, suitable for high-temperature boiler water filtration and industrial hot water treatment. The integrated wedge wire structure is welded using argon arc welding, ensuring no weld defects and high structural strength. The total weight of the water cap is approximately 220g, with a smooth surface treated by passivation to enhance corrosion resistance.
This high-pressure wedge wire water cap is primarily applied in industrial high-pressure water treatment systems, including reverse osmosis (RO) units for industrial pure water production, seawater desalination plants in coastal areas, and high-pressure boiler water filtration systems in power plants. It is also suitable for brackish water treatment projects in mining areas and offshore platform water supply systems, where corrosion resistance and pressure-bearing capacity are critical. In multi-media filters, sand filters, and RO pre-filtration units, it acts as a core water distribution/collection component, ensuring uniform water flow, preventing filter material loss, and improving system filtration efficiency. Its ability to withstand high pressure and corrosion makes it an essential component for large-scale industrial water treatment projects requiring long-term stable operation.
