According to CINI standards, each layer of pressure vessel insulation must be secured with 13 mm wide, 0.5 mm thick stainless steel bands every 300 mm, fastened with butterfly nuts or quick-release fasteners.<\/p>\n
If multiple layers of insulation are used, the joints should be staggered to prevent water droplets from penetrating to the metal surface of the pressure vessel.<\/p>\n
For horizontal pressure vessels, ROCKWOOL roll insulation with one-sided foil facing (ProRox BL938) is used for faster installation. For vertical pressure vessels, <\/span>we use insulation pins welded to the tank wall, then insert ROCKWOOL board insulation (ProRox SL930) through the pins, and finally cover with washers (6 insulation pins\/m\u00b2 in normal areas and 10 pins\/m\u00b2 in the lower part of the vessel).<\/p>\n\n- For insulation thicknesses less than 120 mm, we use insulation pins with a diameter of 4 mm (4 mm nails). <\/li>\n
- For insulation thicknesses greater than 240 mm, we use insulation pins with a diameter of 6 mm (6 mm nails). <\/li>\n
- If there is no gap between the jacket and the insulation during installation, the insulation pins should be 10 cm shorter than the insulation thickness (for 100 mm thick insulation, the nail should be 90 mm long). <\/li>\n<\/ul>\n<\/div>

Support Structures and Spacers for Pressure Vessels<\/h2><\/div>Installing support constructions and spacers is done to bear the weight of the insulation system and maintain the designed insulation thickness.<\/p>\n
If we install insulation without supports, the weight of the insulation could damage the equipment. If we don’t install spacers, the weight of the jacket sheets will compress the insulation, reducing its thickness from the design specifications.<\/p>\n<\/div>
Jacketing Pressure Vessels<\/h2><\/div>Jacketing pressure vessels protects the insulation from weather conditions such as rain, wind, and sun, and prevents scratches that could reduce the insulation’s lifespan.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":39323,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[629],"tags":[],"class_list":["post-39320","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-industrial-work"],"_links":{"self":[{"href":"https:\/\/3t-insulation.com\/en\/wp-json\/wp\/v2\/posts\/39320","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/3t-insulation.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/3t-insulation.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/3t-insulation.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/3t-insulation.com\/en\/wp-json\/wp\/v2\/comments?post=39320"}],"version-history":[{"count":0,"href":"https:\/\/3t-insulation.com\/en\/wp-json\/wp\/v2\/posts\/39320\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/3t-insulation.com\/en\/wp-json\/wp\/v2\/media\/39323"}],"wp:attachment":[{"href":"https:\/\/3t-insulation.com\/en\/wp-json\/wp\/v2\/media?parent=39320"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/3t-insulation.com\/en\/wp-json\/wp\/v2\/categories?post=39320"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/3t-insulation.com\/en\/wp-json\/wp\/v2\/tags?post=39320"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
