For this project, <a href=\"https:\/\/www.equinor.com\/en\/what-we-do\/norwegian-continental-shelf-platforms\/heimdal.html\">called Heimdal<\/a>, two platforms are to be decommissioned and a bypass spool to be implemented between existing lines.<\/p>\n<p style=\"font-weight: 400;\">The first welding device was designed <span style=\"color: #00a7e1;\">25 years ago<\/span> and already used our flexible doors. It was time to replace them and enjoy some technical improvements.<\/p>\n<p style=\"font-weight: 400;\">Perfect sealing is the key to these underwater operations, so our products had to very accurate in terms of dimensions to be as close as possible to the pipe. If not, water would come in and no job could be carried out.<\/p>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;2\/3&#8243;][vc_column_text css_animation=&#8221;right-to-left&#8221;]<\/p>\n<h2><span style=\"font-size: 18pt; color: #00a7e1;\">Pronal&#8217;s solution, flexible doors for underwater welding habitat<\/span><\/h2>\n<p style=\"font-weight: 400;\">Pronal has designed and manufactured two membranes:<\/p>\n<ul>\n<li style=\"font-weight: 400;\">the first one to be used on a 36&#8221; pipe<\/li>\n<li style=\"font-weight: 400;\">the second one to be used on a 32&#8221; ipe (on the opposite side).<\/li>\n<\/ul>\n<p>Those membranes make <a href=\"https:\/\/www.pronal.com\/en\/product\/inflatable-pipe-plugs\/mud-wiper-english\/\">the sealing<\/a> around the pipe. they are vulcanized in one operation and thus completely homogeneous.
