How to properly install copper water pipes?
The following copper pipe quick connectors, copper water pipes and copper water pipe manufacturers will talk about how to install copper water pipes correctly?
1. Communication. Since the decoration company has the owner's design drawings, before installing the copper water pipes, the regular installation team will communicate with the decoration company and the decoration team in a timely and effective manner, so that the decoration company can mark the future water outlet height in advance, so as to Lay the foundation for a smooth installation.
2. Preview. After communicating with the decoration company, the copper water pipes need to be pre-arranged according to the specific room type. The principle at this time is "horizontal and vertical, concise and save materials", because after all, the copper pipe charges are calculated according to the actual usage. of.
3. Unloading. While pre-arranging, you can cut materials at the same time, that is, measure the length of the copper pipe according to different installation positions, and use a saw to cut out the required copper pipe.
4. Prefabricated. After the pre-arrangement and blanking are completed, before the formal welding, a pre-fabrication process is required, that is, the water pipes just pre-arranged are broken into sections and taken out separately for welding in a more open location, so as not to affect the original pre-arrangement. Well arranged effect.
5. Welding.
A. Welding of copper and brass. The welding of copper and brass generally occurs at the terminal outlet. Due to the different properties of the two, flux must be added while welding.
B. Welding of red copper and red copper. The welding of copper to copper generally occurs between tees or elbows, which was also one of the areas prone to water leakage in the past. The trick to solve this problem is to use brazing rods to reinforce the two inner sides of the tee and the inner side of the elbow.
6. Package. In addition to the welding factors mentioned above, another major reason why copper water pipes leak is that copper water pipes will inevitably undergo thermal expansion due to long-term hot water flow. According to our habits, water pipes are mostly buried in cement. If the expansion is not released in the long run, the copper pipe will burst and leak. Therefore, it is recommended that qualified household water pipes be routed from above and not be buried secretly in cement walls. However, considering that some families are really not used to seeing exposed water pipes and it affects the aesthetics of their home decoration, a layer of PEF rubber insulation is wrapped around the copper pipes. This material solves the disadvantage of copper pipes dissipating heat quickly. And because it is extremely elastic, it also solves the problem of copper pipes buried in cement needing to release space.
7. Sealing. After the PEF is tightly wrapped in a spiral shape, the copper water pipes and PEF must be sealed with sealing tape. This not only makes the copper water pipes better insulated, but also makes the hot water copper water pipes and the cold water copper water pipes more insulated. They should be distinguished so that the decoration team will not make mistakes.
8. Test. After following the above steps and installing the copper water pipes, the regular copper water pipe company and the installation team must conduct a water pressure test to confirm that there is no leakage in the water pipe installation.
