The core advantage lies in the high-temperature resistance of 310S stainless steel, solving the pain points of ordinary stainless steel water caps such as easy oxidation and deformation under high-temperature working conditions. 310S stainless steel contains 25% chromium and 20% nickel, offering excellent oxidation and creep resistance, and can operate for a long time at 1200℃ without oxidation peeling, deformation, or fracture. With a maximum working pressure of 15bar, it adapts to the high-pressure working conditions of boiler feed water, avoiding leakage and falling off. The 0.4mm filtration gap is precise and uniform, effectively intercepting scale particles and metal oxides in high-temperature water, preventing their deposition on boiler heating surfaces and reducing thermal efficiency. The threaded connection design facilitates tight fixation with high-temperature filter plates, with no loosening risk under long-term thermal expansion and contraction. The WF3 corrosion resistance class adapts to the corrosive environment of high-temperature steam condensate, with a service life of more than 10 years, far exceeding the service life of ordinary water caps. Certified by ASME, it complies with safety standards for industrial high-temperature equipment, ensuring system operation safety.
Integrally forged and machined from 310S stainless steel, the water cap has a total height of 160mm, with a bottom thread specification of M36×3, adapting to installation holes of high-temperature filter plates. The filtration gap width is 0.4mm, evenly distributed on the side of the cap body, with an open area ratio of 30%, ensuring uniform water flow under high-temperature conditions without short-circuiting. The rated flow is 100L/min, with no deformation or leakage under a maximum pressure of 15bar. The maximum resistant temperature is 1200℃, and the applicable temperature range is 100℃~1200℃, adapting to scenarios such as boiler feed water and high-temperature steam condensate. Each water cap weighs 420g, with a high-temperature passivated surface to enhance oxidation resistance. The threaded connection strength reaches 150MPa, with no loosening risk under thermal expansion and contraction working conditions. The product size tolerance is controlled within ±0.2mm, perfectly adapting to filter plate installation holes, avoiding impurity leakage caused by installation gaps.
It is widely used in pre-treatment systems for boiler feed water in power plants and high-temperature steam condensate treatment links, intercepting scale particles and metal oxides to protect boiler heating surfaces, improve thermal efficiency, and reduce scale cleaning costs. In the chemical industry, it can be used for cooling water filtration in high-temperature reaction kettles and high-temperature steam recovery systems, preventing impurities from entering equipment and causing clogging and corrosion. In the metallurgy industry, it is applicable to feed water filtration in blast furnace hot blast stoves and high-temperature wastewater treatment systems to ensure normal equipment operation. The threaded connection adapts to most high-temperature filter plate installation holes, requiring no additional modification, and can quickly replace old water caps. Certified by ASME, it complies with safety standards for industrial high-temperature equipment, reducing system operation risks.
