Introduction
Flanges are key connecting components in plastic piping systems, designed to achieve secure, leak-proof, and detachable joints between pipes, valves, pumps, and other equipment. Widely applied in industries such as water supply and drainage, chemical processing, wastewater treatment, etc.
Factory visits and third-party inspections are welcome.

Exceptional Mechanical Strength: High tensile strength, yield strength, and impact resistance, capable of withstanding heavy loads, high pressure, and mechanical shocks in harsh industrial environments.
Durability & Long Service Life: Steel materials offer excellent wear resistance and structural stability, with a long service life even in continuous operation. Proper anti-corrosion treatment (e.g., galvanizing, painting, chrome plating) further extends their lifespan in corrosive environments.
Easy Maintenance & Repair: Detachable connection design allows for convenient inspection, maintenance, and replacement of pipeline components (valves, filters, etc.) without damaging the entire piping system.
