The plumbing used in renovations is a PPR pipe with higher safety, longer service life, and easier installation. The installation of PPR pipes is an important part of the hidden project. It is necessary for the decorator to understand the installation process.
Step 1 Material Acceptance
The quality of construction materials will directly affect the quality of the construction and the hidden dangers caused by poor materials used in the future. Before installation, the pipes shall be strictly inspected. The inner and outer walls of the pipes shall be smooth and flat, free from air bubbles, cracks, cracks, dents, peeling, and severe cold spots and obvious marks.
Step 2 live on the bottom
The installer should carefully read the drawings to confirm the location of the water heaters, sinks, washbasins, washing machines, etc., and understand whether the owner or designer has special requirements. If there are special requirements, the construction should be done in accordance with the owner's or designer's instructions.
Step 3 Pipe Cutting
In order to avoid unnecessary waste during the installation process, the installer should measure the length of the required pipe to cut it. The pipe cutting adopts special pipe shearing, and the bayonets of the pipe clip should be adjusted to match the diameter of the pipe to be cut. When rotating and cutting, the force should be evenly applied. When the pipe is broken, the section should be perpendicular to the pipe axis. After cutting, the entire round section of the fracture should be cut. No glitches.
Step 4 Pipe Connection
PPR pipe and pipe fittings are connected by hot-melt method. The hot-melt connection is the most reliable, convenient operation, good airtightness and high interface strength. Before connecting, remove dust and foreign matter from pipes and accessories. The pipeline connection uses a fusion splicer to heat the pipe and fittings. The depth and time of heat fusion of the pipe and fittings should meet the requirements. Do not rotate while welding. When the tubing is connected, the raw material should be wound to ensure sealing.
Step 5 Pipe fixing
In order to ensure that the water pipes will not be resonated due to water pressure in the future, all water pipes must be fixed with a pipe clamp. Pipe clamps with 400mm to 500mm clearance, outer diameters below 25mm, pipe corners and water meters, and 100mm pipe terminations. If the water pipe is in a special situation, the thickness of the mortar must be >100mm.
Pressure check point
â—Ž After the installation of the water pipe, the pressure test shall be conducted. After the installation, the inner wire bend shall be installed with a bulkhead or a triangular valve to ensure the seal.
◎ Water pressure test is to ensure the quality of the water pipe and installation quality test. The pipe pressure test uses a pressure pump to enter the pipe into the pressure ≥ 0.6Mpa (some manufacturers in order to reflect the quality of their own brand pipe, the proposed pipe pressure 0.8Mpa.), pressure The time is not less than 30 minutes and the pressure drops <0.05Mpa.
◎When installing the pipes, they should be horizontal and vertical, left and right cold, with a spacing of ≥30mm. Hot and cold water pipe spacing is not less than 150mm. Hot and cold water pipes can not be worn together with a hole, they should be opened separately. When the water supply pipe and the gas pipe are applied in parallel, the distance is ≥50mm, and the cross-laying distance is ≥10mm. When the balcony needs to install a water pipe, a water valve should be installed.
Supervisor reminds:
When installing the water pipe, the installation personnel will perform strict pressure test under the supervision of the supervision. Therefore, at the time of node acceptance, we only need to pay attention to the problem that the water pipe and pipe fittings are firmly installed and the position is correct, and there is no leakage at the joint. Then observe whether the pipe is left-right hot and cold, and then see if the positions of the faucet and valve are smooth, flexible, normal, and open.Plumbing Water Pipeline Purchasing Hidden Works Decoration Design
