PTFE Lined Elbow
Model:PTFE Lined Elbow
We are one of the renowned name in the market for offering PTFE Lined 45° Elbow and PTFE Lined Elbow 90° Elbow. We can offer the Lining in Elbows as per the requirement of our client. We can offer the Lined Elbow from 1” dia to 12” dia. We manufacture these products in line with the set industry standards.
Kaxite PTFE Lined Elbow is a flanged pipe fitting lined with virgin PTFE, PFA, or FEP to deliver outstanding corrosion resistance in aggressive chemical service. Available in 45° and 90° configurations, the PTFE Lined Elbow provides a smooth, non-stick, chemically inert flow path for direction changes in corrosive pipelines. The carbon steel or stainless steel housing carries the mechanical load, while the fluoropolymer liner isolates the media from the metal surface. Manufactured in compliance with ASTM F1545, these elbows are ideal for chemical, pharmaceutical, and petrochemical plants. Request a quote →
PTFE Lined Elbow – Reliable Corrosion Protection for Direction Changes
Kaxite PTFE Lined Elbow is a precision-engineered flanged pipe fitting designed to handle highly corrosive fluids without compromising structural integrity. The steel outer shell carries the mechanical load, while the internal PTFE liner isolates the transported media from the metal surface, preventing corrosion, contamination, and product build-up. This makes the elbow an ideal choice for direction changes in chemical dosing systems, transfer lines, and process connections.
Our PTFE Lined Elbows are available in both 45° and 90° configurations to suit different pipeline layouts. The liner is available in PTFE, PFA, and FEP to match various temperature and purity requirements. Standard lining thickness is 3 mm, and custom thicknesses can be supplied on request. All elbows are manufactured in accordance with ASTM F1545, with fixed or loose flanges as per client specification. Contact our engineering team for custom sizes, angles, and flange drilling.
Key Features & Benefits
- ✅ Excellent Chemical Resistance – PTFE, PFA, and FEP liners resist virtually all acids, bases, solvents, and oxidizing agents.
- ✅ 45° & 90° Configurations – Available in both standard angles to match any pipeline layout.
- ✅ Temperature Resistant – Continuous service from -29°C to +260°C, depending on the liner material selected.
- ✅ Anti-Corrosive Construction – Steel shell provides pressure containment; the liner protects against media attack.
- ✅ Excellent Surface Finish – Smooth liner surface minimizes friction loss and prevents material accumulation at the bend.
- ✅ Long Service Life – Combines structural strength with outstanding chemical durability.
- ✅ Flexible Liner Options – PTFE, PFA, or FEP available to match your process media and temperature.
