PTFE Lining

PTFE Lining

At Vixon Piping, we have taken pride in being one of the most preferred suppliers and manufacturers of PTFE lining, which is an effective method of preventing corrosion and chemical harm to piping systems and equipment. PTFE or Poly tetra fluoro ethylene is a fluoropolymer that provides the non-stick attribute, chemical inertness and high heat tolerance. Our PTFE linings aim to increase the service life of several pieces of equipment and ensure its efficiency and protection from corrosive agents.
Chemical resistance is one of the most important characteristics of our PTFE lining. It has minimal chemical reactivity to most of the chemicals in its environment.

It can be used in industries that involve the use of highly corrosive materials such as acids, bases and solvents. This resistance helps to preserve the integrity of the piping system so that there is a minimal chance of leakage, contamination, or expensive repairs. PTFE lining is heat resistant and can work from -200°C to +260°C, making it versatile for use in most applications....

This lining also has a low friction coefficient, another important characteristic of PTFE lining. The non-stick surface reduces the friction level and reduces the accumulation of deposits on the surface, thus allowing the free flow of the fluids. This characteristic is especially advantageous in scenarios where it is crucial to keep the environment free of hindrances. In addition, PTFE is non-toxic and has been approved by the FDA for use in food and drug processing industries.
Our PTFE lining is used in chemical processing, oil and gas, water treatment, pharmaceutical and food industries. It is widely applied in piping systems, tanks, reactors, valves and other apparatuses which need protection from corrosive and aggressive media. PTFE lining can be a great addition to your systems as it can increase their working life, improve performance, and meet the high requirements of industries.
At Vixon Piping, we know the need to deliver our products on time and to customer satisfaction. We ensure that our PTFE linings are produced to the highest level of quality and shipped on time to fit your project schedule. Our team is always willing to assist with technical inquiries and determine the most appropriate PTFE lining for your needs.
