Grade 1 covers materials to be used on commercial or industrial systems with operating temperatures from 183 to 104 c 297 to 220 f grade 2 covers material used on industrial systems with operating temperatures from 183 to 150 c 297 to 300 f and grade 3 covers material used on industrial systems with operating temperatures from 183 to 120 c.
Flexible elastomeric cellular thermal insulation.
Even though these insulation materials may have a smooth skin surface on one or both sides they are to be considered homogeneous for.
1 1 this specification covers preformed flexible elastomeric cellular thermal insulation in sheet and tubular form.
1 1 this specification covers preformed flexible elastomeric cellular thermal insulation in sheet and tubular form.
These gases do not change over time and the thermal conduc tivity of the insulation is stable over time.
It is the ideal choice for insulating mechanical piping systems.
This flexibility or modulus issue has two application implications.
First for slide on applications and second in the stresses induced on the seams of the product in applications which cycle from hot to cold and can cause expansion and contraction of the insulation up to ten percent.
Grade 1 covers materials to be used on commercial or industrial systems with operating temperatures from 183 to 104 c 297 to 220 f grade 2 covers material used on industrial systems with operating temperatures from 183 to 175 c 297 to 350 f and grade 3 covers material used on industrial systems with operating temperatures from 183 to 120 c 297 to 250.
