PIPING THERMAL INSULATION
Thermal insulation was produced locally.
Be certain to thermally insulate the piping both on the liquid and gas sides.
• Use thermal insulating materials for piping higher than 120 degree in heat resistance.
Example: EPT - Ethylene, propylene, terpolymer
• Thermally insulate the branch pipe sections using fitting covers (for tees) more than 10mm in thickness or processing thermal
insulation materials as follows.
(Thermal insulation materials for the branch pipes are not supplied as accessories.)
• Seal the branch pipe sections tightly without producing gaps
