As the foreman Jacob Izrailevich insulate my water and sewer with 100 years of warranty
Shalom brothers!
I'll tell you the way to the excellent thermal insulation of the pipe or duct in a country house, which prompted me foreman Yakov Izrailevich. This remarkable endurance Soviet people built my house in Kaluga, and he is involved in all communications.
So that the authorship of the idea of it, I just want to share the positive experience of the three-year operation of its water supply and sewerage.
So, what do we have?
The house is built on an uneven (terraced plot). This imposes a major limitation - it was not possible to bury the pipe below the depth of soil freezing.
Therefore, it was found an elegant solution, which with great pleasure that I share with you today.
So, delivery pipe from the well - 32nd, made of HDPE, quality - drinking. Buried at a depth of 2 meters (at the well) to 40 cm (height differential).
In form it is a goal to peremorzla in any winter. Therefore, Jacob Izrailevich made a cake:
- HDPE 32 tube
- All metal tape winding tube
- sheath tube of porous foam insulation 42mm diameter.
- heating cable 30 W / m, also covered with the metal tape
- Penoplex sheets, pipes laid over the insulation and
The collection pipe system looks something like this:
Nakidal heater - what's the trick?
A trick here in what, let's go "top-down":
- Fromtop freezing we put penoplex - it creates "a heating lens", impervious to the cold.
- Sheath tube 42 mm in diameter and 9 mm thick - prevents side freezing.
- The air gap formed between the foam insulation tubes and heating cable with an adhesive tape, - an optional buffer between the warm and cold zones.
The most powerful is that the heating cable I have not included even in the cold -33 that hit before last winter!
The system itself works, and cable - a kind of safety net Izrailevich Jacob! "In the extreme case," as used to doing their people ...
