The 316H high-temperature stainless steel material is the key feature of this water cap, offering excellent heat resistance and creep strength at temperatures up to 200℃, far exceeding standard 304 or 316 stainless steel water caps. With a flow area of 22.0 cm², it supports a maximum flow rate of 20 m³ per hour, making it suitable for large-scale high-pressure water treatment systems. The outlet precision of ≤0.4 mm effectively retains coarse filter media particles, preventing them from entering high-pressure boilers and causing scale formation. Its service life of over 10 years reduces replacement costs and downtime for power plants and chemical plants. It holds ASME and PED certifications, ensuring compliance with international pressure vessel safety standards.
This high-pressure water cap has a total height of 150 mm, with a cap body diameter of 42 mm and a welded base diameter of 50 mm. It weighs 380 grams per piece, with a weld thickness of 3 mm to ensure structural integrity under high pressure. The flow area measures 22.0 cm², supporting a maximum flow rate of 20 m³ per hour at a working pressure of 2.0 MPa. The outlet filtration precision is ≤0.4 mm, effectively retaining filter media particles with sizes above 1.0 mm, including quartz sand, anthracite, and gravel. It can operate within a temperature range of -30℃ to 200℃, making it suitable for both cryogenic and high-temperature water treatment systems. The maximum working pressure is 2.5 MPa, with a pressure drop of less than 0.04 MPa under nominal flow conditions. The welded base is designed to fit standard 50 mm water distribution pipes in high-pressure filter tanks. It is certified to ASME and PED standards, meeting international pressure vessel and industrial safety regulations.
This water cap is exclusively designed for extreme high-temperature and high-pressure water treatment scenarios in heavy industries. In power plants, it is installed in boiler feedwater treatment systems to filter out suspended solids and prevent scale formation in high-pressure boilers, ensuring safe and efficient boiler operation. In chemical manufacturing plants, it is used in high-temperature cooling water systems for reaction vessels, withstanding extreme temperatures and pressures to maintain stable filtration performance. In oil refineries, it is applied in wastewater treatment systems to filter out oil residues and heavy metal particles under high-pressure conditions. It is also suitable for nuclear power plant pure water preparation systems, where it meets strict safety and reliability requirements. Additionally, it can be used in geothermal power plant water treatment systems, withstanding high-temperature geothermal water and pressure fluctuations.
