Custom PTFE-Lined Filter Factory, Service
Product Description
Core Overview
The PTFE-lined filter is a robust filtration solution engineered for handling highly corrosive and abrasive media in industrial pipelines. Constructed with a durable cast steel or stainless steel body fully lined with virgin Polytetrafluoroethylene (PTFE), it ensures complete isolation of metal components from aggressive fluids such as strong acids, alkalis, and organic solvents. Available in various configurations including Y-strainers and basket filters, this product effectively removes solid particulates to protect downstream equipment like pumps and valves. It is widely used in chemical processing, pharmaceutical manufacturing, water treatment, and power generation industries where reliability, corrosion resistance, and fluid purity are paramount.

Frequently Asked Questions
Due to the chemical inertness of virgin PTFE, this filter is capable of handling strong acids, alkalis, aggressive organic solvents, and abrasive industrial slurries while preventing chemical corrosion of the metallic body.
The standard allowable operating temperature range is -20°C to +180°C, maintaining reliable mechanical strength and chemical stability under standard continuous operations.
Yes. While standard filtration accuracy spans between 20 and 80 mesh, custom mesh ratings and reinforced screen constructions are available based on specific particulate size requirements.
The unit is built with a detachable cover assembly. Operators can easily open the blind flange or bonnet to extract, inspect, clean, or replace the internal screen without unbolting the entire pipeline.
Flanged connections are fully adaptable to international standards including ANSI (Class 150/300), DIN (PN10/PN16/PN25), JIS, and GB standards to integrate smoothly into any existing piping system.
