PTFE / PFA Lined Pipes, Fittings, Flanges & Valves — Frequently Asked Questions
Find answers to common questions about our PTFE / PFA Lined Piping Systems, materials, features, and applications. This is for those looking to buy PTFE lined pipes and understand lined piping price list.
Both PTFE (Polytetrafluoroethylene) and PFA (Perfluoroalkoxy) are fluoropolymers known for excellent chemical resistance. The main difference lies in their processing and temperature capabilities. PTFE offers slightly higher temperature resistance (up to +230°C) and is stiffer, often processed via paste extrusion or isostatic molding. PFA is melt-processable, allowing for injection molding of complex shapes, and offers superior surface finish and translucency. PFA's temperature rating is typically up to +200°C. Both are excellent choices for highly corrosive media, with PFA often preferred for high-purity applications due to its smoother surface.
Yes, Dipti Metal Industries specializes in manufacturing lined piping components designed to withstand full vacuum conditions. Our advanced lining methods, such as paste extrusion and isostatic molding for PTFE, along with careful design and selection of liner thickness (typically 3-10mm), ensure a strong bond between the liner and the outer pipe. This robust construction prevents delamination and collapse under negative pressure, providing reliable performance in critical vacuum processes. All products undergo rigorous spark testing to guarantee lining integrity.
As an ISO 9001:2015 and AS9100 certified manufacturer, our PTFE / PFA lined pipes, fittings, flanges, and valves adhere to stringent international material and dimensional standards. This includes dimensional compliance with ANSI B16.5, DIN (e.g., DIN 2501), JIS (JIS B2220), and BS standards for flanges and fittings. Liner materials conform to ASTM specifications (e.g., ASTM D-1457 for PTFE, ASTM D-3307 for PFA). Each product undergoes comprehensive hydro testing (for pressure integrity) and spark testing (to detect pinholes in the lining), with full Material Test Certificates (MTC) provided.
Our commitment to preventing delamination and failure stems from several critical factors: advanced manufacturing processes (like paste extrusion for PTFE and injection molding for PFA), optimized liner thickness (3-10mm), meticulous surface preparation of the outer material, and superior bonding techniques. Furthermore, every single product undergoes rigorous hydro testing and spark testing. The hydro test verifies the structural integrity under pressure, while the spark test meticulously checks for any micro-porosities or pinholes in the lining that could compromise performance, especially under vacuum or high-temperature cycling. These measures ensure a robust, long-lasting liner integrity.
Yes, we offer both anti-static and virgin (food-grade) options for our PTFE / PFA lined products up to certain nominal bore sizes. Anti-static linings are crucial for safely handling flammable or explosive chemicals by dissipating static charges, preventing spark discharge. Virgin materials, free from additives or recycled content, are essential for high-purity applications in pharmaceuticals, food & beverage, and semiconductor industries, ensuring no leaching or product contamination. Please specify these requirements when requesting a quote to ensure we provide the appropriate material.
