And at <strong>much lower temperatures of those required for the melting<\/strong> process of the metals.<\/p>\n<p>How is it possible? I&#8217;m not going too much in depth with details, which can be found online. Essentially, the exchangers are placed inside <strong>special furnaces<\/strong>, under vacuum conditions, where they reach <strong>temperatures equal to 65, 70 or 75% than the melting temperature<\/strong> and under pressure the permeation of the crystalline structure is achieved. Therefore, the process generates <strong>extremely resistant welding joints<\/strong> without material addiction and with no additional weight.<\/p>\n<p><iframe loading=\"lazy\" title=\"DIFFUSION BONDING\" width=\"750\" height=\"422\" src=\"https:\/\/www.youtube.com\/embed\/ikhC1TxkEZ0?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p>This special construction process has many applications in a variety of sectors including main sectors such as <strong>aerospace<\/strong>, <strong>oil and gas<\/strong> and also the <a href=\"https:\/\/www.tempco.it\/blog\/en\/9657\/tempco-pche-exchangers-in-hydrogen-guide-2024\/\" target=\"_blank\" rel=\"noopener\"><strong>hydrogen industry<\/strong><\/a> which is actually a really emerging trend sector.<\/p>\n<p>These exchangers offer a lot of advantages and some disadvantage. Among the disadvantages is the construction process that increases costs, because it employs special furnaces and a very peculiar processing that requires long cycle times and thus higher costs.<\/p>\n<p>On the side of advantages, the fact that these are exchangers made in a unique material and fully welded and so they offer a very <strong>high resistance to extremely high pressures and temperature levels<\/strong>. This technology can be applied both to <strong>stainless steel exchangers and in titanium<\/strong>, but also to different materials, where the technology becomes a little more complicated.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Diffusion Bonding is a special welding technology allowing to obtain innovative plate heat exchangers resistant to very high pressure and temperatures, to be employed in sectors such as aerospace, oil and gas and hydrogen applications.<\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[64,63,113,473,110],"tags":[3994,3774,495,138,897,3320,2951,3993,3853,123,3992,3938,1543,3976,3930,3977,892],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v20.5 -
