you need
  • - trumpet;
  • - insulation;
  • - corrugated PVC pipe or other material for the sleeve;
  • - punch;
  • - ugoloshlifovalnaya machine (Bulgarian);
  • - Drill;
  • - foam;
  • - jigsaw.
Measure the diameter of the pipe and determine the size of the hole.For hot water pipe or system "warm floors" aperture should be 70% larger than the diameter of the pipe, to ensure safety of the structure under thermal expansion.Sewage and cold water supply pipes with clearance can be smaller.If the tube will be warmed, be sure to note the thickness of the insulation.
With punch or angle grinders (Bulgarian) with diamond disc drill a hole under pipe in the wall.Please make as many holes on the perimeter and some - in the center of the intended range.Then set chiseling hammer mode and all unnecessary Hollow inside th
e hole.
Set inside wall protective plastic sleeve, such as a metal or corrugated polyethylene pipe.The inner diameter of this sleeve should be 5-10 mm larger than the outer diameter of the pipe.If you plan to pipe inside the wall, and use corrugated PVC pipe, as they can withstand the shrinkage of cement mortar.
to lay pipes does not move inside the sleeve and at the same time was able to expand freely when heated, surrounded by its insulation, for example, Penofol, foiled Isover, foamed polyethylene or polyurethane (any mild, non-flammable, waterproofpictures).Optimal insulation thickness - 8-10 mm.
If the pipe passes through a wide wall or over a large area, make the centering support of construction foam.They will support pipe in Stroebe, which in this case can not fill, but only close the cover plate.
Try not to fix pipe in the wall, it must have the possibility of longitudinal movement.Provide free site to the nearest obstacle, for hot water supply pipe of not less than 7 mm, the heating system - at least 10 mm (calculation 1 meter straight pipe).
