8. Features & Applications

• Key Features:
• High-Temperature Alloy Construction (F22): Chrome-Molybdenum alloy steel (ASTM A182 F22) provides excellent strength and oxidation resistance at elevated temperatures up to 550°C, making it ideal for high-temperature steam and hydrocarbon services .
• Forged Body: Forged construction ensures superior strength, grain structure integrity, and freedom from porosity, critical for high-pressure Class 800 applications .
• Y Pattern Design: Compact Y-shaped body minimizes pressure drop while providing effective debris removal .
• Removable Stainless Steel Screen: Easy maintenance – screen can be removed for cleaning without removing the strainer from the pipeline .
• Bolted / Screwed Bonnet: Secure seal design with high-temperature gasket (graphite) for reliable operation .
• Multiple End Options: Available in NPT threaded, socket weld, or butt weld connections to suit various piping specifications .
• Equipment Protection: Protects downstream equipment such as control valves, pumps, steam traps, and flow meters from damaging debris .
• Versatile Installation: Can be installed in horizontal or vertical (downward flow) pipelines .
• Customizable Filtration: Standard 20 mesh screen with optional finer meshes (40, 60, 80, 100) or perforated screens available based on application requirements .
• Main Applications:
• High-Temperature Steam Systems: Power plants, boiler houses, steam distribution networks .
• Refineries & Petrochemical Plants: Hydrocarbon processing, high-temperature oil and gas lines.
• Thermal Oil / Heat Transfer Systems: Protecting pumps and heaters from debris .
• Process Industry: Chemical processing, high-temperature fluid filtration.
• Upstream of Critical Equipment: Installed before control valves, steam traps, flow meters, and pumps .
• Condensate Lines: Removing rust and scale from condensate return systems .

*Disclaimer: The above data is prepared based on common industry standards (API 602, ASME B16.34) for forged alloy steel Y strainers. Specific dimensions, materials, and pressure ratings may vary by manufacturer. F22 alloy is specially suited for high-temperature service up to 550°C. The final technical agreement and certified drawings shall prevail.*

GARANTIE:

SAVVY VALVES streeft naar uitzonderlijke productkwaliteit en zorgeloze aftersalesservice. Onze kleppen hebben een gegarandeerde minimale levensduur van 12 maanden. Gedurende deze periode leveren wij alle benodigde reserveonderdelen en gedetailleerde onderhoudsinstructies gratis. Mocht er binnen de garantieperiode schade ontstaan ​​die niet door mensen is veroorzaakt, dan vervangen wij kosteloos de onderdelen en bieden wij professionele technische ondersteuning. Na de garantieperiode hoeven klanten alleen de kosten van de reserveonderdelen te betalen en profiteren zij nog steeds van kortingen op onderhoudsdiensten. Ons doel is om klanten te helpen de operationele kosten te verlagen en de productie-efficiëntie te verbeteren door middel van betrouwbare kwaliteit en uitgebreide aftersalesservice. Of het nu gaat om technische vragen of onderhoudsbehoeften, ons deskundige team reageert snel om ervoor te zorgen dat uw klepsysteem te allen tijde optimaal blijft presteren.
