Z-shaped elements
If the working substance temperature differs from the ambient temperature, the pipeline is subjected to mechanical stress. The reason is the thermal deformation of metal. If the heating main is laid underground, another negative factor impacting the system is the soil pressure. Thermal expansion results in friction against the soil which causes the line’s wear.
Compensation during temperature variations is provided by the Z-shaped compensator. It can also be used as a transition piece between underground and above-ground heating main. In this case, the expansion joint is used as a connecting part between different levels of the line. When compensators are installed, the growth of hydraulic resistance in the pipeline must be taken into account.
Z-shaped PUF elements are produced according to the GOST standard and undergo all the required tests. Two bends are welded to the straight pipe run on both sides. The visual resemblance to the letter Z comes from the fact that the bend outlets face to the opposite sides. Next, the rapid remote control system is installed along the length of the pipe, and the complete structured is insulated with polyurethane foam and covered by the protective shell.
Zinc-plated Z-shaped compensators are used for above-ground laying, and polyethylene compensators – for underground laying
These compensators are affordable, because they are fairly simple in terms of manufacture and installation. However, due to the design, they are heavy and bulky, so we recommend our clients to make arrangements for delivering the item to the work location. You can review our product range and purchase compensators at attractive prices on the web-site of Saverhot PK LLC. You can place the order yourself by filling-in a form.
