3.24. Insulation
1. Insulation should be calculated as a function of piping operating temperature and ambient conditions. The ambient reference temperature should be calculated as the average of the minimum values occurring in the coldest month of the year for hot insulation and the average of the maximum values occurring in the hottest month of the year for cold insulation.
2. The design for thickness and type of various insulations should be made in accordance with standards.
3. To reduce the possibility of condensation within the bellows, thermal insulation or screening may be used, but the bellows material should not be subjected to a continuously high temperature that would lead to an unacceptable fatigue life.
