Irregular insulation installation
Thread Content
There are corresponding construction specifications for insulation; construction without following these specifications is considered unacceptable. Neither internal nor external insulation has been applied, and no moisture barrier layer is visible either. An important point is that in cases where heat tracing pipes are used, it is necessary to enclose both the heat tracing pipes and the main pipes with wire mesh first, and then apply the insulation layer outside the mesh, thereby preventing the insulation material from getting between the heat tracing pipes and the main pipes and affecting the heat tracing effect.
Irregular insulation work mainly results from not following the construction specifications, with a lack of necessary internal and external insulation layers as well as moisture-proof layers. In the case of heat tracing pipes, a wire mesh should first be wrapped around the main pipe and the heat tracing pipes, before the insulation layer is applied, to prevent the insulation material from being inserted between them and compromising the heat tracing effect. .
Whether it is qualified or not depends on the approval of the on-site supervisor or the owner’s representative. Everyone in this circle knows what standards are, and there are contractual bases for them. The reason for this phenomenon is that as long as it is inspected and approved by someone, it is considered qualified. Those who have the right can pursue accountability; those without such rights had better refrain from giving advice. One should think carefully before trying to block someone’s path to making money :)
Process supervision and construction quality inspection are very important
I still need to remind people: when such situations are encountered, some people are unaware of them, while others are aware but think it doesn’t matter and has no impact
Process control of construction quality is very important; strict inspections and implementation are required at key stages
Anti-corrosion and insulation are the areas in the chemical industry that generate the most revenue, as well as those where non-compliance is most common.
If the construction quality of the equipment’s main body is poor, how can one expect proper insulation work?
I remember there was a specification stating that the heat tracing tube should be at a certain distance from the main pipe and not in close contact with it? Forgot what the guidelines are
