At the beginning, people used heating stoves for heating, and later on economic development and technological development. People began to use heating and heating, installing heating pipes at home, and artificially burning coal and heating pipes to circulate water. This ensures the circulation of hot water to obtain heat. Later, with the improvement of people's aesthetics, there was warmth in the ground, and the floor heating pipe appeared at this time. The floor heating pipe is mainly used for burying in the ground, or at the bottom of the house, which does not affect the appearance, but also guarantees heating. The original floor heating pipe may be a stainless steel pipe, and it is easily corroded. However, with the improvement of the production process, there is now a history of ppr heating pipes, and the historical source of floor heating pipes has reduced unnecessary troubles.
1, in the specified cooling time, just welded joints can also be corrected, can be a small amount of rotation, but after the cooling time, forced correction is strictly prohibited. Note: The connected pipes and fittings must not be tilted. The basic level should be vertical and horizontal. Avoid the wrong angle when installing the mixer and it cannot be installed normally.
2. During the specified cooling time, it is forbidden to allow the newly processed joint to withstand external forces.
3. When using fitting fittings for PPr-sourced ppr pipes with metallic threads, the white raw tape must be tightly sealed to avoid water leakage from the threads.
4. When over-tightening PP-R pipe fittings with metal threads, there may be cracks in the pipe fittings that cause water leakage. Pay attention to moderate force.
5, to use a professional tube card fixed, do not use hook nails to prevent damage to the water pipe, reducing the life of the water pipe. The distance between the cold water pipe clamps is 50±5cm, and the hot water pipe clamp spacing is 35±5cm. If the pipe clamps are not in place, the water pipes will shake and cause noise.
6. The direction of the water pipe should be horizontal and vertical. Under the premise that the groove is horizontal and vertical, avoid pulling or twisting the water pipe, causing the water outlet and the wall not to be parallel, affecting the appearance and installation of the mixing faucet.
7, when the waterway transformation, to the installation of electric water heaters, sub-tap and other reserved cold, hot water pipe.
