Lined cross are used in piping systems to manage multi-directional flow of corrosive or reactive fluids, ensuring reliable performance and long-term protection against chemical attacks.
PTFE Lined Cross
We are PTFE Lined Cross Pipe manufacturers in India. It is a specialized pipe fitting for complex piping networks where fluid is distributed or collected through four intersecting lines. PTFE Lined Cross is fully lined with high-performance fluoropolymers such as PTFE, PFA, FEP, or PVDF to provide an effective barrier against corrosive and abrasive media. Constructed with robust materials like ductile iron or carbon steel, the fitting ensures leak-proof connections and minimizes contamination, making it essential in industries like chemical processing, pharmaceuticals, and petrochemicals.
Technically, lined cross fittings are engineered to meet stringent industrial standards. They are available in various sizes, rated for pressures up to 150# (10-15 PN), and perform efficiently from sub-freezing temperatures up to 200°C. With a uniform lining thickness of 3 mm to 6 mm, these fittings maintain excellent adhesion and durability, conforming to face-to-face dimensions specified by ANSI B16.10 and DIN 3202. Rigorous hydraulic and spark testing further confirms their operational safety and structural integrity.
Incorporating PTFE Lined Cross fittings into your system offers significant benefits, including enhanced performance and sustainability. Their fully lined design eliminates direct metal-to-fluid contact, preventing corrosion and reducing maintenance needs, which translates into lower downtime and operating costs. Additionally, the cross configuration ensures balanced fluid distribution with minimized pressure drops, supporting efficient flow and a safer working environment while contributing to sustainable industrial practices.
