PUF U-shaped elements
Even in the normal conditions of operation, mechanical stresses are produced in steel pipes of a heating main resulting in wear. The main cause of this phenomenon is the thermal expansion of materials. This happens when the temperature values of the energy carrier and the environment are significantly different. If the line is laid using the trenchless method, then, besides other destructive impacts, there is the force of friction formed by the pressure of the soil layer.
The U-shaped element is designed as the compensator during thermal deformations. If homing action, calculated at the design stage and ensured by the proper configuration of the system, may not be used, the pipeline is fitted with expansion joints.
A U-shaped compensator is designed as follows: two bends are connected to the inlet and outlet of a steel pipe at a square angle by welding. The element’s name comes from the fact that the bends look in the same direction, and the product resembles the letter U.
You can find U-shaped elements with PUF insulation at our web-site. Specifications of the products are strictly defined by GOST and undergo all necessary inspections. The size and weight of compensators are determined individually for each project. A steel U-shaped compensator is insulated with polyurethane foam and tightly covered by the protective enclosure. For heat networks laid underground, the element is mounted in the horizontal position. If pipes are installed above ground, the compensator is positioned vertically.
You can check on the prices of PUF compensators and place your order at the web-site of Saverhot PK LLC. For the comfort of clients, we provide delivery services.
