The PTFE lined pipeline flame arrester is installed in strong acid and strong alkali special pipelines to adapt to corrosive environments with strong acid and strong alkali, as well as the needs of multiple special fields such as petroleum, chemical industry, and food. PTFE is lined inside the valve of the conventional flame arrester to isolate the medium and valve body, achieving anti-corrosion effect. It has strong functionality, small size, lightweight and pleasant, reliable performance, and simple matching. It has been widely used in many fields such as petroleum, chemical industry, metallurgy, medicine, etc. This product adopts a high-temperature molding lining fluoroplastic process, coated with a layer of anti-corrosion materials such as perfluoroethylene propylene (F46), polytetrafluoroethylene (PTFE), soluble polytetrafluoroethylene (PFA), etc. It can completely cut off the contact between corrosive media and the valve body shell, ensuring the safety of pipeline transportation.

The main advantages of PTFE lined PTFE flame arresters are:

High temperature resistance - operating temperature up to 250 ℃

Low temperature resistance - with good mechanical toughness; Even if the temperature drops to -196 ℃, a 5% elongation can be maintained.

Corrosion resistance - shows inertness and resistance to strong acids, alkalis, water, and various organic solvents for most chemicals and solvents.

Climate resistance - has an aging lifespan in plastics.

High lubrication - refers to the low friction coefficient among solid materials.

Non adhesion - refers to the small surface tension of solid materials that do not adhere to any substance.

Non toxic - has physiological inertness and is non-toxic to living organisms.
