Water supply pipe is one of the frequently used pipes in our daily life. Its installation involves the safety and stability of water supply, so strict installation specifications must be followed.
The specifications and types of water supply pipes and pipe fittings should meet the design requirements and have a factory certificate. The inside and outside of the pipe wall should be smooth and tidy, galvanized uniformly, and free of rust, cracks, burrs and other quality problems. Strict and effective measures must be taken to prevent damage, corrosion or deterioration of water supply pipes and pipe fittings during transportation, storage and construction.
The specifications of the water meter should meet the design requirements, and the water company has confirmed that the hot water system needs to use a hot water meter that meets the temperature requirements.
Engineering materials such as concrete, mortar, anti-corrosion and waterproof coatings prepared on site must be tested and qualified before being used.
After the pipeline is installed, the water pressure test shall be carried out according to the test pressure value determined by the design requirements and the construction specifications; the pipeline shall be flushed before the acceptance to make the water quality meet the specified cleanliness requirements, and the relevant unit shall be checked and accepted. Ensure that the acceptance records are complete and correct.
For sub-projects that have undergone repair or reinforcement treatment, and can still meet the structural safety and functional requirements after changing the external dimensions, the professional quality inspector of the construction project must be organized by a professional supervision engineer to re-check and accept; but it still remains after the repair or reinforcement treatment Acceptance inspections are prohibited for sub-projects that cannot meet the structural safety or functional requirements.
