[home decoration network] in the construction of floor heating, we should try our best to avoid damage to the pipes, so as to improve the stability of the pipes in use, especially pay attention to the scratch of the pipes under the water separator and at the 90 degree turn in the laying of the thermocline. In this regard, local heating companies generally adopt the following three methods:

first, directly bend the pipe to the required curvature without any auxiliary tools or materials. The disadvantages of this method are: it is easy to cause the pipe diameter of the bending part to shrink, or even dead break, affecting the water flow; After connection, the pipes rebound due to tension, and the connection with the water separator is easy to loosen and fall off under the impact of high-pressure water flow; The bending angle is not easy to control, and the appearance is relatively scattered after installation

II. Insert the spring under the water separator into the floor heating pipe, force excessive bending, and then connect the water separator. The disadvantage of this method is: in the process of forced excessive bending, although the pipe does not shrink, it overstretches the local outside of the pipe, and even causes irreparable whitening of the outer wall of the floor heating pipe, which destroys the pressure bearing force and reliability of the pipe

III. use metal elbow clamps to assist in bending and positioning of pipes. Although this method can solve the shortcomings of the above two methods, because it is made of metal stamping, most of the flash burrs formed by stamping will scratch the floor heating pipe during installation, which greatly reduces the temperature resistance and pressure resistance of the floor heating pipe; In addition, due to the inconsistency between the thermal expansion coefficient and expansion force of the floor heating pipe and the metal elbow, in the long-term thermal expansion and cold contraction friction process, coupled with the outward tension of the pipe itself, the depth of the scratch is aggravated, resulting in the leakage of the floor heating pipe, which has buried serious hidden dangers for the safety of the floor heating system

due to the following advantages, the plastic elbow clamp is expected to completely solve the technical problems such as the stability, unity, safety and standard of the 90 degree turn of the ground heating pipe:

1. Save trouble: the installation of the pipe under the water separator only needs to clamp the plastic elbow onto the pipe, which can effectively solve the problems of pipe distortion, springback, dead bending, diameter reduction and so on, which is very convenient

2. Increase the service life of floor heating: installing pipes with plastic elbow clamps can effectively avoid scratches and bleaching in the installation process. Facts have proved that the cost of using plastic elbow clamps is far lower than the cost of repairing scratches and bleaching of pipes; The safety and reliability of floor heating pipes are improved, thereby increasing the service life of floor heating

3. High safety: support the pipe vertically under the water separator through the plastic elbow clamp to prevent the pipe from springback and increase stability

4. When impacted by high-pressure water flow, it can effectively prevent the interface between floor heating pipe and water separator from loosening

5. Never rust: all plastic materials are used, so there is no need to worry about rust after installation, and the service life is the same as that of the floor heating pipe

6. Aesthetics: the owner will feel that the pipe installation of the exposed part of the water separator is standardized, neat and unified, which improves the value and grade of floor heating
