Water supply pipeline installation in clean workshop
According to the design drawings, draw the construction drawings with the contents of pipeline shunt, pipe diameter, reducing diameter, reserved nozzle and valve position, etc., mark the actual installation structure position, and measure the actual installation according to the marked sections The clean workshop cleans the lumen before installation of the dry pipe, removes the asphalt at the outer end of the socket inside the socket, and arranges the socket in sequence in the direction of the incoming water. Fix the pipe; the bend and beginning of the pipe should be supported firmly to prevent axial movement during twisting, and all pipe openings should be blocked at any time.
Housing pipes and fixing brackets are installed at the wall penetrations of hot water pipes according to the design requirements, and the expansion joints are installed in accordance with regulations and pre-stretched. Adjust the slope, and there should be ventilation at the high point and drainage device at the low point; the installation of the riser is unified from top to bottom, and the prefabricated riser is arranged in layers according to the number and installed in sequence. Correct the marks during straightening, expose 2-3 buttons of the threads, remove the hemp heads, and check whether the height and direction of the reserved openings are correct; apply anti-rust paint to the exposed threads and the damaged parts of the galvanized layer, and the openings of the branch pipes are all Add temporary screw plugs; the installation direction of the riser door should be easy to operate and repair, and use a wire pendant to straighten it after installation; two elbows should be used to connect the riser and the conduit, and when the straight length of the riser is greater than 15m, the Three elbows are used, if the riser is installed with a retractor, it is the same as the main pipe. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean workshops and gene amplification laboratories.
The one-way hydraulic test should be done before the water supply pipelines laid, installed and insulated before being concealed, and the comprehensive hydraulic test should be conducted after the pipeline system is installed; during the hydraulic test, clean air will be released, and then pressurized after being filled with water. Stop the pressurization when the specified requirements are reached, and check. If there is no leakage from each joint and valve, continue to the specified time and observe that the pressure drop is within the allowable range. After the pressure test is completed, the pipeline can be flushed, and tap water should be used for flushing continuously. To carry out, should ensure that there is sufficient flow, and go through the acceptance procedures after washing and cleaning; the anti-corrosion of water supply pipeline laying and installation shall be constructed according to design requirements and national acceptance standards.
