Do the pipes after pressurization by the expander need insulation?
Thread Content
Is insulation required for the outlet pipe at the pressure-boosting end of the expander?
I think it depends on the requirements of the manufacturing process; if heat is needed, then the heat can be retained in the heat exchange equipment, and if it’s not necessary, then there’s no problem – the heat can simply be dissipated.
I think this heat preservation is considered from an overall perspective, taking into account the differences between the south and the north. . Is it because winter in the north is below minus 30 degrees, which has a significant impact on the equipment?
No need. Have you checked the insulation on the pipes between the compressor stages? If An requests it, heat insulation to prevent burns can be added.
It is for sound insulation, not heat insulation.
Has soundproofing been done? Why? Is it still required by the environmental impact assessment? What kind of soundproofing material was used? ~~
The noise insulation requirements are not specified in the environmental impact assessment; it is only required that the ambient noise levels meet national standards. In practice, users can install insulation and silencers on the inlet and outlet pipes of compressor-type equipment in order to reduce environmental noise pollution in the factory area and surrounding regions, thereby protecting the health of workers! The outlet pipe at the pressurized end of the expander does not need insulation; a heat exchanger is connected right after it to cool the fluid. What’s the point of maintaining a certain temperature then? The sub-zero temperatures in the north have little impact on the continuous high temperatures above 100 degrees! For such soundproofing materials, high-temperature resistant porous materials such as slag wool can be used!
I’m just worried that the safety department will say that insulation is needed to prevent burns~~ Hehe~~
