How to insulate pipes with polyurethane foam, and what should be taken into account? I would appreciate some guidance from experts: handshake :handshake
Based on the actual conditions on site, there are both finished pipes and sheets, as well as those produced through on-site foaming. . . . . Special attention should be paid to the insulation layer and joint areas. . . . .
When using rigid polyurethane foam pipe sleeves for insulation in pipelines, attention should be paid to the treatment of the joints in the sleeve material. When using the on-site integral foaming process, attention should be paid to the ratio of black and white materials, proper control of the foaming density, and the demolding process. For reference!
How should the seams of the sleeve material be treated?
For the construction of pipeline insulation, first, the joints must be tight; second, a moisture barrier must be installed
Should foaming be done on-site or use pre-made pipes for insulation? For cost-effective insulation of pipes, it is essential to choose appropriate pipe sleeves, and there should be no gaps at the joints ； Each section should be secured with thin wire ； Outsourced asphalt shingle ； It is best to cover it with protective material such as glass cloth. Pay attention to thickness and bulk density. On-site foaming is mainly related to thickness.
