Sandwich pipe for chimney has internal and external contours of stainless steel. The thickness of the metal and, accordingly, the cost of the product may vary. Vermiculite is placed between the two pipes. This material has excellent thermal insulation characteristics, it is non-flammable and durable. Insulation is made from natural ingredients and does not emit harmful substances when heated.
Sandwich pipe for chimney 150 mm in diameter, as well as products of other sizes, is produced from 500 to 1000 mm long
Pay attention to the following design features:
When welding stainless steel sheets, modern technology is used, which guarantees high quality and complete tightness of the seam.
All pipes have a bell-shaped device for quick and reliable connection between themselves and auxiliary elements.
Vermiculite thermal insulation can withstand temperatures up to 1200 degrees without changing its characteristics.
The thickness of the insulation is from 40 to 50 mm, which is enough for standard operating modes of heating systems.
For the outer and inner layers, the metal of increased strength, durable and wear-resistant is used.
The lifetime of the chimney (depending on the intensity) is from 10 to 15 years.
