Regarding the location of seams on insulated aluminum sheets
Thread Content
According to my previous workplace, it is located at 135 degrees. As shown in the figure below, **the standard seems to no longer be within a 45-degree range of a vertical line. I think there seems to be a problem with the national standards; once it rains, if something is placed on top, rainwater will seep in through the gaps and cause corrosion, or substances leaking from other chemical pipelines can corrode the joints.
Standards are set by humans, and they are not without any flaws.
The seam cannot be at the very top. Also, the seams of each aluminum tube must not be on the same straight line; they should be offset from each other.
The seam cannot be at the very top, and the layer outside the seam’s edge should slope downward.
I thought it was necessary to take leaks into account
There are standards for thermal insulation with leopard print, and these issues are taken into account
I would like to ask: which standard specifies insulation aluminum foil? Thank you
GB50216-2008 Code for Thermal Insulation of Equipment and Piping
Code for Construction of Insulation Works for Industrial Equipment and Piping «GB50126-2008» Code for Acceptance of Construction Quality of Insulation Works for Industrial Equipment and Piping (GB50185-2010)
I thought it was always a clip, though? Is welding still needed? If it’s welded, rain will reach that area anyway; isn’t corrosion protection taken into account when selecting materials?
