Double Wall Insulated Spiral
SSei has a complete line of Double Wall pipe and fittings.
Each piece is fabricated with an inner metal liner (either perforated or solid) surrounded by insulation from 1”-4” thick and covered by a solid metal outer shell, with an option Mylar layer.Concentricity of liner to outer shell is maintained by mechanical means on all fittings and pipe with more than 1″ of insulation.

The inner liner is available in either perforated or solid metal. Perforations are 3/32 inch diameter with an overall open area of 23%.

Inner liners are 24 gauge for 3″ through 36″ round and 22 gauge for 38″ through 58″ round.

Internal insulation with perforated inner wall material can reduce radiated noise by 25 dB or more.
Our standard 1-inch insulation has a thermal conductance of 0.27 Btu/hr x sq. ft. x degree Fahrenheit.
Where fiber erosion is of special concern, Mylar can be applied to the perforated sheet metal liner.
