With advanced lining processes such as surface treatment, fusion bonding and exact molding, we provide leak-free smooth finishes. Our fluoropolymers, i.e., PTFE, FEP and PFA, have exceptional chemical resistance, thermal stability, low friction, and anti-stick qualities and are perfect for challenging industrial uses. Supplying sectors like chemical processing, oil and gas, pharma and food and beverage, our range of products encompasses slip-on, weld neck, blind and lap joint flanges, with custom fabrication options to suit special project needs.
PTFE-lined flanges are a vital element in industrial piping systems with a lining of Polytetrafluoroethylene (PTFE) a very strong fluoropolymer characterized by its high chemical resistance non-stick surface and thermal stability. The flanges are commonly used in toxic and corrosive chemical treatment systems in order to offer a leak-proof connection between pipes and equipment. Kali PTFE lining serves as a protective sleeve, covering the metal flange against corrosive liquids to avoid corrosion, contamination and leaks. Widely used in industries like chemical processing, pharmaceutical, food and beverage and oil and gas, PTFE-lined flanges are of several types, including slip-on, weld neck, blind and lap joint types. Custom manufacturing can also be arranged to suit individual application needs. Their reliability and durable performance render them essential for safe and efficient fluid handling in harsh industrial applications.
Kali PTFE Lining is a leading supplier of PTFE Lined Flanges in Malaysia, Kuala Lumpur, offering high-quality, corrosion-resistant solutions ideal for chemical, pharmaceutical, and industrial applications.

Ideal for handling aggressive chemicals and corrosive media
Ensures tight sealing and prevents fluid leakage
Available in various flange types and sizes to fit specific applications
Minimizes downtime and reduces overall maintenance costs
A flange with a lining features a corrosion-resistant material, like PTFE or HDPE, bonded inside for enhanced durability and chemical resistance.
Use lined flanges in piping systems that carry corrosive, high-purity, or reactive chemicals.
Yes, they have pressure/temperature ratings based on the liner and base metal, typically up to 150 psi and 200°C (392°F).
Align flange faces, insert gasket, secure bolts evenly in a star pattern, torque to specification, and check for leaks.
