5.1 APPLICATION

A. HOT PIPING

Specification
Code No.

 
 

1501-H

Hot Application – Intermediate Temperature (15°C - 315°C)

 

 

– Piping: Pipe covering without integral jacket shall be held in place with insulation fastening at not less than 300 mm centres. Pipe insulation with integral jacket shall be held in place by stapling the flap on 75 mm centres. Pipe insulation with integral self-sealing jacket will not require additional fastening.

– Fittings: Insulate fittings with sections of the pipe insulation mitred to fit tightly, or insulating cement, or with tightly placed flexible insulation covered with reinforcing membrane stapled in place. Alternately insulate fittings with tightly placed flexible insulation and apply PVC fitting covers.

– Valves, Strainers: Insulate valve bodies and strainers with insulating cement, or fitted pipe insulation segments, or mitred blocks all to thickness of the adjacent pipe insulation or insulate with tightly placed flexible insulation covered with reinforcing membrane stapled in place. Drains, blowoff plugs and caps shall be left uncovered. Alternately insulate with tightly placed flexible insulation and apply PVC fitting covers. (See Note 1).

– Flanges: Insulate flanges with oversized pipe covering or mitred blocks to and applied in accordance with the manufacturer's directions. (See Note 2) the thickness of the adjacent pipe covering. Alternately insulate with tightly placed flexible insulation and apply PVC fitting covers. (See Note 1)

– Insulation Termination Points: Terminate insulation 75mm from fittings to provide working clearance and bevel insulation at 45° angle.

 

1501-HA

Alternative Application

 
 

– For certain areas where insulation application as described above is impractical, flexible foamed elastomeric or closed cell insulation may be used and applied in accordance with the manufacturer's directions (See Note 2).

 

Note 1: The use of this code number does not include insulation application on valve bodies, strainers or flanges. The specifying authority must specify in the project specifications if valve bodies, strainers or flanges are to be insulated. Refer to specification format, Page SF-4, under "Application".

Note 2: The National Building Code 1995 requires that in buildings of non-combustible construction, foamed plastic insulation on piping located in vertical service spaces or in rooms or spaces other than service spaces must be suitably protected from fire exposure. The specifying authority is responsible for ensuring such protection is provided, if applicable to a project, and specify accordingly in the project specifications. The use of foamed plastic insulation is also limited by NBC 1995 requirements for Smoke Developed Classification. The specifier must determine such limitations for each project and specify accordingly. Also note the temperature limitation of these products.
