Product Overview
The PTFE lined equal tee is a high-performance piping component engineered for complex corrosive environments. It features a robust outer shell made of carbon steel or stainless steel, internally lined with Polytetrafluoroethylene (PTFE), often referred to as the "King of Plastics." This design perfectly integrates the mechanical strength of metal with the world-class chemical stability of PTFE, providing a safe and reliable solution for branching or merging highly aggressive media.
Technical Specifications
Diameter Range: DN25 – DN600 (Custom sizes and reducing tees available upon request).
Lining Materials: Virgin PTFE, antistatic (conductive) PTFE, or modified PTFE.
Housing Materials: High-quality carbon steel (e.g., ASTM A234 WPB) or stainless steel (SS304, SS316L).
Working Pressure: Standard ratings include PN10, PN16, PN25 (Class 150/300); higher pressure designs available.
Connection Type: Flanged ends (fixed or loose/lap-joint flanges) complying with international standards (ASME B16.5, EN1092-1, DIN, etc.).
Lining Thickness: Typically ranges from 3mm to 6mm depending on the diameter to ensure maximum permeation resistance.
Key Features & Advantages
Ultimate Corrosion Resistance: The virgin PTFE lining is resistant to nearly all chemical media, including concentrated nitric acid, aqua regia, strong alkalis, and organic solvents, with the exception of molten alkali metals and elemental fluorine.
Superior Permeation Resistance: Utilizing advanced lining techniques (such as ram extrusion or molding), the PTFE is tightly bonded to the steel wall, preventing media permeation that could lead to shell corrosion and ensuring overall structural integrity.
Wide Temperature Adaptability: Designed to operate reliably within a temperature range of –50°C to +200°C, maintaining excellent sealing and stability even under frequent thermal cycling.
Non-stick & Anti-scaling: The extremely low surface energy of PTFE provides a smooth, non-stick interior that minimizes fluid friction and prevents sediment buildup, ensuring long-term flow efficiency and media purity.
Robust Mechanical Strength: The metal housing bears the system pressure and external loads, ensuring the lining remains secure and does not collapse or displace under vacuum or high-pressure pulses.
Low Maintenance Costs: The exceptional service life and low failure rate significantly reduce downtime and operational risks in demanding chemical processing plants.
PTFE lined equal tees are essential for systems requiring the distribution of highly corrosive media, such as:
Fine Chemical & Petrochemical: Acid-base intermediate circulation and material distribution systems.
Chlor-Alkali Industry: Transporting wet chlorine, brine, and caustic soda.
Pharmaceutical & Biotech: Sterile material transport requiring high purity and corrosion resistance.
Semiconductor Industry: Distribution of ultra-pure chemicals and electronic-grade acids.
Metallurgy & Power: Pickling lines, flue gas desulfurization (FGD), and strong oxidant handling.
The PTFE lined equal tee is a critical component for addressing corrosion at piping junctions. It provides not only unmatched chemical protection but also the structural security necessary for industrial safety. Whether in high-purity pharmaceutical lines or harsh heavy-chemical processes, it is the dependable choice for fluid control and distribution.
