AI Technical Summary
Existing cleanroom piping in biopharmaceutical workshops has poor insulation performance in high-temperature environments, and glass fibers and particulate matter are prone to falling off, affecting the clean environment.
The system employs stainless steel inner pipes and a segmented insulation structure, including a first insulation structure for the outdoor section and a second insulation structure for the indoor section. It uses stainless steel sleeves and polyurethane foam insulation filler, combined with fixed supports and sealant, to ensure the insulation effect of the pipeline and prevent material from falling off.
It achieves effective heat preservation in high-temperature environments while preventing the shedding of glass fibers and particles, thus maintaining the cleanliness of the cleanroom.
