It is designed to ensure maximum reliability in the most demanding applications. Its advanced structure features a dual sealing system: a smooth metallic inner ring coated with expanded PTFE acts as the primary barrier, while the spiral wound element functions as the secondary seal.<\/p>\n<p>Thanks to the expanded PTFE coating, the inner ring not only provides reliable sealing but also protects the spiral and the flanges from corrosion, abrasion, and scaling. This makes it an ideal solution for plants operating under aggressive conditions, such as alkylation units, where flange integrity is often compromised by erosive phenomena and solid deposits.<\/p>\n<h3>Operating Conditions<\/h3>\n<ul>\n<li>Operating Temperature*: from -200\u00b0C to +260\u00b0C<\/li>\n<li>Pressure*: up to 100 bar<br \/>\n<em>*Maximum theoretical values<\/em><\/li>\n<\/ul>\n<h3>Certifications Spiral Wound Gasket for HF-Alky Services<\/h3>\n<ul>\n<li>VDI 2440 \u2013 Fugitive Emissions<\/li>\n<li>API 6FB \u2013 Fire Test<\/li>\n<\/ul>\n<h3>Patent<\/h3>\n<p>Patent filed with the Italian Ministry of Economic Development<\/p>\n<h3>Your Gasket, Configured to Your Plant Specifications<\/h3>\n<p>Each plant has its own line specifications, including the use of specific materials.
