Metaflex® - spiral wound gaskets

Description
This gasket is certified for emission control applications.

James Walker Metaflex® gaskets will seal flanges where temperature, pressure, vibration or rates of flow are beyond the capability of conventional jointing materials.

They are wound in V-section metal strip and a softer filler material so that flange faces are presented with a spiral of alternate metal/filler layers.


Typical applications
Pipelines and pressure vessels on steam, petrochemical, nuclear, marine and hydraulic plant; also heat exchangers. Metaflex® Lolode gaskets are recommended for flange joints where bolt loading is limited.

Prime features

• Gaskets are made in a wide variety of sizes and shapes.
• Combinations of metal strip and filler are selected to suit the specific fluid media and operating conditions.
• Quick to install and remove.
• Operating temperatures from cryogenic up to 1000°C.
• System pressures from high vacuum to over 35MPa/350bar.
• Support rings - inside and/or outside of the spiral - make gaskets suitable for high line pressures on flat or raised flange faces.

Specifications

• Metaflex® gaskets with graphite or PTFE fillers are certified as meeting TA-Luft emission control requirements.
• Products are manufactured in accordance with all relevant gasket standards to suit flange designations: ASME B16.5, BS1560 (only part 3.2 is still current), ASME B16.47 Series A (MSS-SP44), ASME B16.47 Series B (ASME B16.47 supersedes API605), BS EN 1092 (supersedes BS4504); plus DIN, JIS and NF.
