Polyurethane Foam (PUF) maxiumum design temperature

Polyurethane Foam (PUF) maxiumum design temperature

Polyurethane Foam (PUF) maxiumum design temperature

(OP)
Which is the common accepted maximum design temperature for PUF insulation material to be used in a Pipe in Pipe sealine? Is it possible to use up to 110 °C or even more? Thanks

RE: Polyurethane Foam (PUF) maxiumum design temperature

PU foam max. temp. is 100-120 deg.C, depends on quality.
So I should say it´s acceptable.

RE: Polyurethane Foam (PUF) maxiumum design temperature

Do you mean design temperature of the foam, or design temperature of the pipeline?

Assuming that you are selecting the foam on the basis of pipeline maximum operating temperature, a typical maximum quoted for wet service moulded PU is 115 deg C (ref SPE 131618 ExxonMobil).  Therefore, it suggests that a dry service maximum for PU foam could be higher.  However, any rated temperature should be demonstrated by appropriate qualification testing.

I mean the maximum temperature above wich PUF is commonly used. The temperature above which the PUF can have insulation problem and material structure degrade.
