UFC 4-214-02, 24 Jul 03
resin plastic (RTRP) piping manufactured by the filament winding process. The casing pipe
shall be wound to meet ASTM D 2310 classification RTRP and ASTM D 2996. The resin shall
be a polyester isothalic resin. The outer surface shall be coated with a pigmented, protected
resin containing a parafinated wax and ultraviolet inhibitors. Casing thickness shall be 5 mm for
100 mm and below carrier pipe sizes and 6.5 mm for carrier pipe sizes above 100 mm.
Condensate piping shall not be located in casings which contain any other piping.
4-16.3.2 End seals. Each preinsulated section of piping shall completely seal the insulation,
providing a permanent water and vapor seal at each end. Preinsulated factory fabricated
sections of piping modified in the field shall be provided with an end seal which is equivalent to
the end seals furnished with the preinsulated section of piping.
4-16.3.3 Pipe coupling, steam. Coupling shall be of a multi-stage seal designed to
accommodate the expansion and contraction of the system in the coupling. Couplings shall be
of corrosion resistant materials. The annular seals and carrier pipe ends shall be specifically
designed to protect the seals and resist abrasion due to lateral loads in the system.
4-16.3.4 Pipe coupling, condensate. Coupling shall be a single stage seal design to
accommodate the expansion and contraction of the adjacent pipes. Coupling shall be of
corrosion resistant materials. The annular seals and carrier pipe ends shall be specifically
designed to protect the seals and resist abrasion due to lateral loads in the system.
4-16.4
Insulation. The minimum thickness of insulation for the heat distribution system shall
be in accordance with Tables 1 and 2.
