Model PS & IPS
Positive Pressure Piping System

mb1.jpg (19166 bytes)

Selkirk Metalbestos Model PS and IPS are modular, prefabricated piping systems which incorporates flanged joints designed for both quick assembly and pressure-sealing capabilities. They offer a combination of insulated piping components as well as the structural accessories needed for support and attachment to building structures. Expansion joints are available both in gasket designs and in pressure tight, all-welded bellows designs.

Standard gas-carrying piping parts are usable for a wide variety of applications:

    · Chimneys and stacks for all types of building heating equipment.
    · Chimneys for industrial ovens, furnaces, and processing equipment.
    · Exhaust piping for engines or turbine units.
    · Ducting in restaurants for compliance with Type 1 hood requirements.
    · Ducting for heated air and combustion products
    · Ducting for light duty pollution control equipment.
    · Venting for engine exhaust and other shipboard systems.
    · Venting for offshore drilling rigs.

Fiber insulation increases the diameter of the outer wall on Model IPSC2 and IPSC4 pipe fittings. Shown in this sequence is the same 8-inch diameter inner pipe. (Photo 1) Without insulation the outside diameter of the pipe is 10-inches. (Photo 2) This is also true of the same pipe with a 1-inch layer of insulation. (Photo 3) However, the same 8-inch pipe with 2-inch insulation results in an outside diameter of 12 inches. (Photo 4) Adding 4 inches of fiber insulation makes the diameter of the outer wall 16 inches.

Rugged, safe double wall construction provides permanent insulation and keeps the inner pipe hot and the outer pipe relatively cool. Outer pipe is aluminum. Each end is dye formed to assure uniform size and easy joint connection.
