Safety Shield material types

Flangeguards supply Spray Shields manufactured using the following material types, please click on the links below for further information;

 

 

 

PTFE Safety Shields

Our most popular shield, compatible with practically all corrosive chemicals (incl. caustic, high concentration sulphuric) due to the technical fabric and Teflon/Kevlar thread used for stitching. See our ‘chemical resistance guide’ for further clarification.

This shield is typically used for acids, caustics, solvents, fuel, lubrication and seal oil applications. In addition to the pipe joint types listed on this website, the PTFE shield can be made to fit a wide range of other fittings such as valves, pumps, expansion joints and hoses (contact us for further details).

Max working temp: 235 °C / 450 °F
Flange Ratings:  Ansi 150 - 600lb  /  DIN PN6 – PN40
Pipe sizes: Standard; ¼” (10mm) – 24” (600mm). Larger sizes available please contact us
Applications: Standard; Flanges, Elbow, Tees, Couplings. Other types available please contact us

PTFE-CLEAR Safety Shields

This shield is generally used for applications where sight of the flange/joint must not be obscured. Thus, liquid releases can be seen within the shield, providing visual indication. It should be noted however, that we do not recommend this shield for applications where external liquid / condensation may result in a false indication of leakage.

The shield is suitable for a range of corrosive chemicals due to the technical fabric and Teflon/Kevlar thread used for stitching. See our ‘chemical resistance guide’ for further clarification. For strong acids and higher temperatures and pressures, please consider the standard PTFE or ST/ST shield.

Typically used for acids, caustics, solvents, fuel, lubrication and seal oil applications. In addition to the pipe joint types listed on this website, the PTFE-CLEAR shield can be made to fit a wide range of other fittings such as valves, pumps, expansion joints and hoses (contact us for further details).

Max working temp:  150 °C / 300 °F
Flange Ratings:  Ansi 150 - 300lb  /  DIN PN6 – PN40
Pipe sizes: Standard; ¼” (10mm) – 24” (600mm). Larger sizes available please contact us
Applications: Standard; Flanges, Elbow, Tees, Couplings. Other types available please contact us

PVC Safety Shields

This shield is made from heat-sealed PVC and is designed to provide a ‘budget’ or short-term solution for low corrosion, pressure and temperature applications. Typically used for water-based liquids and particularly low-concentration chemicals. Each shield comes with external litmus indicator patch.

Max working temp: 60 °C / 150 °F
Flange Ratings: Ansi 150 - 300lb  /  DIN PN6 – PN25
Pipe sizes: ¼” (10mm) – 24” (600mm). Larger sizes available, contact us
Applications: Flanges, Elbows, Tees, Couplings

STAINLESS STEEL Safety Shields

This shield comprises outer 316 st/st band, inner 4-layer st/st mesh and external quick-release clamp. The key design feature is the internal mesh which effectively diffuses all pressure from the release, resulting in a safe drip. Equally important is the exact alignment of the shield and ‘crimped’ central mesh section, as other ill-fitting shields may create additional lateral spray-outs or dangerous mist formation. 

Typically used for fuel, lubrication, seal & hydraulic oil, steam and other chemicals. Its design and materials of construction make it suitable for applications involving high temperature and pressure. Currently only available for flanges – though we can supply shielding solutions for ‘special’ applications so feel free to contact us for further consultation.

Max working temp: 500 °C / 930 °F
Flange Ratings: Ansi 150 - 1500lb  /  DIN PN6 – PN100
Pipe sizes: Standard; ¼” (15mm) – 24” (600mm). Larger sizes available, contact us
Applications:  Flanges
