Now, with the provision of living standards, people attach importance to drinking water health, and more people choose Stainless steel pipe It is used as drinking water pipeline. Then, in different installation projects, Stainless steel water pipe What are the precautions in the overall installation process? Now let's introduce science to everyone.

1. The spacing between the supports of thin-walled stainless steel pipes should not be greater than that specified in the following table. The spacing between the fixed supports of hot water pipes should be determined according to the thermal expansion amount of the pipeline, the allowable compensation amount of the expansion joint, etc. The contact between the fixed support and the pipe should be tightly fixed and firm. The movable support should be flexible. There should be a gap of 3-5 mm between the sliding bracket and the sliding bracket.

2. Surface mounting Drainage pipeline Stainless steel pipe clamp should be used for the movable support of Water pipe installation Plastic pipe clamps can also be used. If other metal supports or pipe clamps are used, soft spacers such as wood or rubber should be used between the contact surfaces on both sides.

3. Metal pipe clamps or hangers shall be used to fix the water supply hydrants and water distribution points. The pipe clamps or hangers should be set 40mm-80mm away from the fittings.

4. The buried pipe shall be protected from the acid alkali corrosion of the soil on the outer wall of the pipe or the damage of sharp and hard sundries. Wrapping anti-corrosion measures should be taken, such as wrapping two layers of polyethylene tape, or coating epoxy resin, and then wrapping glass fiber plastic cloth.

5. The pipe sleeve shall be set when the pipe passes through the floor slab and load-bearing wall. The diameter of the embedded sleeve shall be 1-2 larger than that of the stainless steel pipe. The plastic pipe can be used as the pipe sleeve. When the pipe passes through the roof and basement exterior wall, the metal pipe sleeve shall be used. Plastic pipe can be used in other occasions. The sleeve shall be 20mm higher than the ground and roof, and strict waterproof measures shall be taken.

6. When laying the pipeline, there shall be no axial distortion. When crossing the wall and floor, there shall be no forced correction. After installation, there shall be no waist collapse, arching waves and twisted snaking.

7. When the pipeline is buried, it should be below the local frozen line. If it needs to be laid above the frozen line, reliable insulation and moisture-proof measures should be taken. In non frozen areas, when buried, the buried depth of the pipe top should not be less than 50cm, and the buried depth of the part crossing the road should not be less than 70cm.

8. The width of wall slot of embedded concealed pipe can be the outer diameter of pipe plus 50mm, and the depth can be the outer diameter of pipe plus 15-30mm.
