PVC FRPC filter cartridge housing

PVC FRPC filter cartridge housings are high-performance pressure vessels specifically designed to house and protect filter cartridges of various specifications (such as PP cotton, activated carbon, resin, membrane elements, etc.). Their core design philosophy lies in combining the superior corrosion resistance of PVC (polyvinyl chloride) with the high structural strength of FRPC (fiber-reinforced polymer composite) to create a reliable housing capable of withstanding harsh chemical environments and system operating pressures.

Key Features and Advantages

Superior Corrosion Resistance

The main body and media contact parts are made of industrial-grade PVC or CPVC material, exhibiting excellent corrosion resistance to most acids, alkalis, salts, and oxidizing media. This completely solves the problem of easy corrosion and rusting of metal shells, making it particularly suitable for handling seawater, chemical fluids, and acid/alkali solutions.

High Strength and Lightweight

The FRPC fiber reinforcement layer, like “steel bars,” is wound around the outside of the PVC inner liner, significantly improving the shell’s burst pressure and circumferential strength, enabling it to safely withstand higher working pressures (commonly up to 10 bar or higher).Compared to all-metal shells for the same pressure, the weight is significantly reduced, facilitating transportation, installation, and maintenance.

Safe and Reliable Design

Multi-layer Structure: Typically a composite design of an inner anti-corrosion layer (PVC), a reinforcing structural layer (FRPC), and an outer protective layer (resin/pigment), each with its specific function.Explosion-proof Design: Rigorous hydrostatic burst testing ensures a high safety factor and safe operation within the specified pressure range.High-Quality Sealing: Utilizing a multi-threaded or clamp-type quick-opening structure, coupled with chemically resistant food-grade silicone or EPDM O-rings, ensures zero leakage.

Versatility and Convenience

Standard Interfaces: Inlet and outlet ports typically employ internationally recognized NPT internal threads or union designs, facilitating connection to various piping systems.Transparent Viewing Window (Optional): Some models feature a transparent viewing window on the top or housing, allowing for direct observation of the internal filter cartridge status or liquid condition.

Easy Operation: The quick-opening end cap design allows for rapid opening without special tools, making filter cartridge replacement simple and efficient.

Main Application Areas
  • Industrial Water Treatment: Pre-treatment filtration for reverse osmosis (RO) systems to remove sediments and colloids.
  • Chemical and Electroplating Industries: Filtration of acid and alkali solutions, process circulating water, and electroplating solutions.
  • Food and Beverage Industry: Coarse filtration of process water, syrups, and beverages (materials must meet relevant food contact standards).
  • Laboratory and Pharmaceutical Industries: Primary filtration of deionized water (DI water) and ultrapure water (UP water).
  • Environmental Protection and Water Purification: Reclaimed water reuse, seawater desalination pretreatment, and swimming pool water circulation filtration.
  • Agricultural Irrigation: Water filtration for drip irrigation and sprinkler irrigation systems to prevent sprinkler head clogging.
