A PTFE Flange Guard (also known as a Flange Spray Shield) is a protective device designed to prevent hazardous leaks or sprays of corrosive or toxic chemicals at flange joints in pipelines. These guards are especially important in industries where aggressive chemicals are transported under pressure.

Material: Made from Polytetrafluoroethylene (PTFE), which is a highly chemical-resistant fluoropolymer. It is ideal for protecting against a wide range of acids, bases, and solvents.

Design: Typically constructed as a flexible, wrap-around shield with:
Drawstrings or Velcro closures for secure attachment.
Transparent inspection window (optional) made from fluoropolymer film to allow visual monitoring of leaks.
Drainage hole or pH indicator patch (optional) to detect leaks without removing the guard.

Purpose:
Prevents dangerous spray-outs in case of gasket failure.
Protects personnel and equipment from chemical exposure.
Helps maintain a safe work environment in chemical processing, pharmaceuticals, petrochemicals, and other industrial sectors.

Installation: Easy to install and remove without the need for special tools. It wraps around the flange and is secured using the built-in fastening system.
