The PTFE lined flame arrester is installed in the special pipeline of strong acid and alkali to meet the needs of some corrosive environments with strong acid and strong alkali, petroleum, chemical industry, food and other special fields. It is installed in the valve of the conventional flame arrestor. It is lined with PTFE to isolate the medium from the valve body and achieve the anti-corrosion effect. It has strong functions, small size, light and cheap, reliable performance and simple matching. It has been widely used in many fields such as petroleum, chemical industry, metallurgy, medicine and so on. This product adopts high temperature molding process of lining fluorine plastic, and is coated with a layer of anti-corrosion materials such as polyperfluoroethylene propylene (F46), polytetrafluoroethylene (PTFE), soluble polytetrafluoroethylene (PFA), etc., which can completely cut off the corrosiveness. The contact between the medium and the valve body shell ensures the safety of pipeline transportation.

The main advantages of PTFE lined PTFE flame arrestor:

High temperature resistance-working temperature up to 250℃

Low temperature resistance-has good mechanical toughness; even if the temperature drops to -196 ℃, it can maintain 5% elongation.

Corrosion resistance-It is inert to most chemicals and solvents, and can withstand strong acids and alkalis, water and various organic solvents.

Weather resistance-has the aging life in plastics.

High lubrication-is the low coefficient of friction among solid materials.

Non-adhesion-is the small surface tension of solid materials, and does not adhere to any substances.

Non-toxic-It is physiologically inert and non-toxic to organisms.
