scope:
This specification establishes the requirements for anti-sweat, refrigerant, and thermal foam insulation (see 6.1 and 6.6.2) for use on piping, pipe components, ventilation ducts, and machinery. This material is not approved for use on bulkheads, decks, or other surfaces.
Classification. Insulation is of the following types, grades, classes, and forms, as specified (see 6.2).
Types.
a. Type I: Anti-sweat and refrigerant insulation for piping, pipe components, and machinery (surface ships and submarines)
b. Type II: Thermal insulation for hot piping applications (180 °F maximum for submarines and 300 °F maximum for surface ships)
c. Type III: Thermal insulation for ventilation ducts
Grades.
a. Grade A: For unlagged applications
b. Grade B: For lagged applications
Classes.
a. Class 1: -20 to 180 °F maximum operating temperature
b. Class 2: -20 to 300 °F maximum operating temperature
Forms.
a. Form 1: Tubular
b. Form 2: Sheet
Purpose. The NAVSEA Chief Engineer's (CHENG's) intent for issuing reference (a) is to provide a non-proprietary procurement specification for affordable, easy-to-handle insulation for piping, machinery, ventilation ducts, and anti-sweat refrigerant lines.
intended Use:
The insulation covered by this specification is intended for anti-sweat, refrigerant, and thermal insulation only and may be used in either sheet or tubular form. The insulation is intended for... View More
