While in civil and residential installations the male-female socket connection with silicone gasket is the standard solution, in contexts requiring frequent disassembly, high tightness, scheduled inspections, or large nominal diameters, the <strong>flanged flue pipe<\/strong> and the corresponding <strong>flange joint<\/strong> represent the preferred technical solution. Understanding the construction features, available types, and correct applications of this joining technology is essential for professionals designing and managing flue systems.<\/p>\n<h2>What is a flanged flue pipe<\/h2>\n<p>A <strong>flanged flue pipe<\/strong> is a modular component in which the ends of the duct are equipped with flanges \u2014 flat metal rings with bolt holes \u2014 allowing mechanical connection with other flanged elements. Unlike socket systems, the <strong>flanged pipe<\/strong> is connected by bolting two opposing flanges together with a high-temperature gasket in between.<\/p>\n<p>Flanges are typically welded to the pipe using TIG welding to ensure full metal continuity. Alternatively, loose flanges (rotating flanges) can be used to simplify alignment during installation.<\/p>\n<h2>Materials<\/h2>\n<p>Materials depend on flue gas characteristics: AISI 316L for corrosive environments, AISI 304 for standard applications. Carbon steel flanges may be used in large-diameter systems for cost efficiency when not in direct contact with flue gases.<\/p>\n<h2>Flange joint: operation and types<\/h2>\n<p>The <strong>flange joint<\/strong> connects flanged pipes or equipment. Tightness is achieved by compressing a gasket between flanges using bolts.<\/p>\n<h2>Advantages of flanged systems<\/h2>\n<ul>\n<li><strong>Repeatable disassembly<\/strong> for maintenance and inspections<\/li>\n<li><strong>High-pressure resistance<\/strong> (up to class H1)<\/li>\n<li><strong>Connection versatility<\/strong> with standard flanged equipment<\/li>\n<li><strong>Ease of alignment<\/strong> during installation<\/li>\n<\/ul>\n<h2>Applications<\/h2>\n<ul>\n<li>Heating plants and industrial systems<\/li>\n<li>High-pressure flue systems<\/li>\n<li>Large-diameter ducts (>300 mm)<\/li>\n<li>Systems requiring frequent maintenance<\/li>\n<li>Connections to filters, silencers, heat recovery units<\/li>\n<li>Modular or temporary installations<\/li>\n<\/ul>\n<h2>A professional solution<\/h2>\n<p>Flanged systems ensure reliability, durability, and compliance in demanding environments.<\/p>\n<p>MT Camini offers stainless steel flanged systems with technical support for design and installation.<\/p>\n<p>Contact us for technical consultation.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Features, advantages and applications in industrial systems In medium- and large-scale flue gas evacuation systems \u2014 industrial plants, heating plants, power generators \u2014 the joining method between duct components plays a critical technical role.
