Around his knees and tees on the vertical and horizontal pipes, installed in the wall under the plaster, you should leave the space of 3-4, see end of the pipe should be located so as to have a place for free movement. Before I put the tube into the recesses on the walls, should wrap it with kraft paper or other similar material. You can plaster deepening to install pipes, having closed with a PEX plate while leaving sufficient space for expansion of the pipe. Wall plaster after will be an experimental extension.
You can also use the foam pads on the front and (or) the rear surface of the pipe. Thus, in the depression will be enough room for expansion to 1-2 mm. If the pipe to the cold PEX plumbing is not in the wall, but inside the building, it should consolidate the holders of every 40 see the attachment or holder to be screwed to the wall is very durable. These adaptations also leave room for free movement during the expansion and extension tubes.
When laying pipes for hot water or heating factor expansion and extension should be considered in advance. There are three ways the pipe: in the walls, mines and on the walls. In principle, when installed in the walls of the expansion factor of pipes shall not be considered. It is only necessary to leave enough room for expansion. If the extension is more than a place occupied by insulating material, a material made of a tube, to compensate for their expansion.
Any change in pipe length due to temperature changes, can be stopped coated plaster with lime mortar or cement surface. The pressure caused by the internal movement of extension and expansion will be absorbed by the material tube.
Since the coefficient of linear thermal expansion of reinforced pipe is different from the coefficient of expansion pipe with an aluminum layer, assembly exits the pipe installation in the mines need to perform in view of the selected pipe.
If the rigid attachment is directly at each branch pipe, then the sill installation no need to use compensators.
Typically, the installation of pipes shall carve through stationary locking fasteners. Thus, the expansion will be directed to areas of pipe between the fixed points of fixation, where the coefficient of expansion is not too high. Note that the distance between two stationary locking fasteners shall not exceed 3 m.
When installing the pipe, which has no stabilizing aluminum strip, you should leave the place (in proportion to the length of the pipe used) for its free movement.
