First, the material requirements For aluminum plastic pipe, copper parts and valves, etc., to check the appearance of the quality, size and dimensions are complete, check the factory certificate, and sent to the laboratory retest, the conclusion must meet the design and specification requirements.
Second, the construction tools Steel springs, special scissors, the whole mouth, wrenches, screwdrivers, red packets and rubber hammers.
Third, the preparation for construction 1. Technical disclosure carefully read the product specification, familiar with the drawings, the development of the best construction program, detailed disclosure to the workers.
2. To do the model room First install the model room, familiar with the operation process, summarize the operating essentials, and then fully spread after inspection.
Fourth, the operating process 1. Process pre-embedded to a straight suspension, bombs, casing production and installation of a clip fixed a material to install a test a test run.
2. Pre-preparation When the wall is built, the wooden bricks are embedded in the clamps, and holes are reserved for walls and boards. Wooden tiles should be treated with anti-corrosion treatment. The burying should be firm and the location should be accurate and consistent.
3. Hang straight, elastic line, casing production and installation Interspersed with the progress of construction, from the highest point to pull the line, hanging straight, buried casing, and leave a high water level. After the completion of the wall veneer or plastering, the vertical and horizontal lines will pop up.
4. Fix the clips Cut the wooden tile along the horizontal and vertical lines. Use long screws to tighten the clips. Pay attention to the protection of the glazed brick wall.
5. Feeding According to the system, layer, section of the pipe length of a good tube, cutting, numbering, put away, and should pay attention to the following points.
(1) Unified measurement and centralized material selection must be accurate and the number classification should be clear.
(2) Straightening Aluminium-plastic tubes are supplied in rolls, usually taking 3-4m at a time, roughly taken straight and then cut as needed, then leaned against straight angle steel and hammered straight with a rubber mallet.
(3) Cutting It is more convenient to cut with a special cutter. It is also possible to use a hacksaw or other cutting machine. However, the entire mouthpiece must be used to round the nozzle before installation.
(4) Bending The minimum bending radius of aluminum-plastic tubes is 5D (9D is the diameter of aluminum-plastic tubes), and the bending radius should be well mastered. Make sure to insert the inner spring when making the bend, then lightly bend it on the mold and hammer it with a rubber mallet.
(5) Pre-assembly Parts of the pipe and pipe sections that can be pre-assembled should be assembled first. Pipes and fittings are inserted and clamped. Check whether the rubber gaskets and gaskets are complete. Tighten the tubes as far as possible and tighten them with a wrench. The threaded connection between pipe fittings and pipe fittings should be kept in the same way as the galvanized pipe.
6. Installation Follow the order of the main and the rear and the first and the later. Specific procedures to facilitate the construction prevail. Hang and fasten at any time. After the installation is complete, do a full quality inspection.
7. Test, test run Do hydraulic pressure test, check for leaks and tighten, adjust to pass. Then clean the pipeline, run through the water and do a good job of construction records.
V. Quality Control The installation of aluminum-plastic pipes can be checked with reference to the inspection and evaluation standards for the quality of PVC pipe installations, but the following points should be noted.
1. The variety and quality of materials meet the requirements and there are retest reports.
2. Pre-buried, reserved properly, straight pipes, and securely installed. The spacing between the clips is preferably 50-100cm.
3. Pipe cutting and bending must not be damaged. Damaged pipes and fittings are strictly prohibited.
Sixth, need to improve the problem 1. The quality of the pad, gasket directly affects the pipe's tightness, durability, should improve its quality, reduce the leakage phenomenon.
2. The pipe material has good flexibility, but its rigidity is slightly poor. It is easily deformed due to external force disturbance, affecting the appearance of the pipe, and it is easy to seep at the joint. Care should be taken during construction and maintenance.
3. The fixing method of the existing clips needs to be improved. Refer to the PVC clips and use them instead of holding the cards or using expansion bolts.
4. If the copper pieces are connected with copper pieces or other accessories when they are too tight and brittle, the quality of the copper pieces needs to be improved.
Second, the construction tools Steel springs, special scissors, the whole mouth, wrenches, screwdrivers, red packets and rubber hammers.
