FRP Pressure Vessels – 2.5″ NPSM Series for Water Treatment
High-performance FRP pressure vessel featuring a standard 2.5″ NPSM threaded opening. Designed for residential and light commercial water treatment, this tank is universally compatible with Runxin, Fleck, and Clack control valves, making it the ideal housing for water softeners, carbon filters, and RO pre-treatment systems.
商品説明
The Backbone of Efficient Water Filtration Systems.
The Stark 2.5″ NPSM Series is our most versatile line of composite fiberglass pressure vessels. Unlike traditional steel tanks that are prone to rust and heavy to handle, our composite vessels feature a seamless high-density polyethylene (HDPE) inner liner wound with continuous fiberglass strands and sealed with high-grade epoxy resin.
This advanced construction ensures 100% corrosion-free performance and zero contamination, making it perfect for drinking water applications and critical RO pre-treatment stages.
Technical Note:
Our tanks undergo rigorous burst pressure and fatigue testing. For detailed structural stress analysis, raw material composition, or specific manufacturing protocols, please reference the official technical data at our specialized manufacturing division:

アドバンテージ・ワン
Corrosion-Resistant Composite Construction
Stark FRP vessels are engineered to outlast traditional steel tanks in aggressive water environments. The inner shell is molded from seamless, food-grade High-Density Polyethylene (HDPE), ensuring that water never touches metal. This guarantees zero rust and no heavy metal leaching. The outer shell is reinforced with continuous strands of fiberglass embedded in high-performance epoxy resin, providing a pressure rating of 150 PSI (10.5 Bar) while being 60% lighter than steel equivalents.アドバンテージ2
Universal Compatibility & Easy Maintenance
Designed with the system integrator in mind, the 2.5″ NPSM threaded top opening is manufactured with precision tolerances to ensure a leak-free seal with all major control valve brands, including Runxin, Fleck, Clack, and Autotrol. The lightweight composite structure simplifies transport and installation, allowing a single technician to position the tank and load media (Resin, Carbon, or Sand) without the need for heavy lifting equipment.関連商品
