Igloo Thermal - Introduction to Phenolic Foam - Non-combustible Phenolic Foam

Phenolic Foam Insulation Performance at -150°C

Experiment

Dewar thermos bottle
(-196°C liquid nitrogen inside)

Phenolic insulation pipe has good performance in cold & hot water pipes and petroleum pipelines. It has great advantages in low temperature and cryogenic field. The experiment of phenolic foam insulation performance at -153°C is as follows:

The equipment of experiment
• Dewar thermos bottle
• (-196°C liquid nitrogen inside),
• phenolic insulation pipe (28 insulation layers at 40mm)
• buffer tank thermometer

Experiment Process

Connect the equipment of experiment

Stage 1 :

Connect Dewar thermos bottle (-196°C liquid nitrogen inside) to "S" shape phenolic insulation pipe.

With a length of insulation pipe measuring 30 meters, connect the thermometer to the phenolic insulation pipe to inspect the temperature of inner insulation pipe which then Connects the end of insulation pipe to buffer tank.

Stage 2 :

Open the Dewar thermos bottle (-196°C liquid nitrogen inside) and buffer tank, then you can see the white mist emitted from one side of buffer tank, start to measure the temperature. Close the Dewar thermos bottle (-196°C liquid nitrogen inside) and buffer tank at the same time when the thermometer shows -150°C, the 30 meter insulation pipe then has filled up with liquid nitrogen at this point.

Stage 3 :

Maintain 12 hours

Stage 4 :

12 hours later, observe the thermometer to show -141°C the dimension of insulation pipe is 28 mm thickness of insulation material is 40mm.

Stage 5 - Conclusion:

Phenolic insulation pipe has good insulation performance in supper low temperatures and cryogenic liquid containers, without distortion and contraction have remained in perfect condition.
