Matters needing attention in heat preservation construction of HVAC insulation l
Posted by sere on November 26th, 2019
The connection of the insulation pins to the surface of the air pipe, parts and equipment may be made by bonding or welding.Make sure that the bond is firmly in place to prevent it from falling off.After welding, we should pay attention to keep the air pipe flat, and not affect the corrosion resistance of galvanized steel plate.In terms of quantity, the number of pins per square metre should not be less than 16, the side should not be less than 10, and the top surface should not be less than 8 The distance from the first row insulation pins to the edge of the duct or insulation material shall not be less than that of 120mm. In addition to the above two points, we should also note that the thickness of the adiabatic layer in the flange of the air duct should not be less than 0.8 times the thickness of the insulation layer of the duct. If the joint of heat insulation material has moisture proof and heat insulation layer, it is necessary to seal it with viscose tape. The width of the adhesive tape should not be less than that of 50mm.The constructors should also make sure that the adhesive tape is firmly attached to the moisture-proof surface, and that there can be no swelling and cracking and shedding.
I hope it will help u!
