construction measures of double-wall corrugated hdpe water supply pipe

Double wall corrugated hdpe water supply pipe is used in many places. In order to ensure the application of double wall corrugated hdpe water supply pipe, there will be many matters needing attention in the project.

1, double-wall corrugated hdpe water supply pipe paving should first use a level to find the center line of the pipeline, in the detection of its elevation.

2, double-wall corrugated hdpe water supply pipe paving inch first with non-metallic material rope cut off both sides of the pipe body, maintain the pipe body balanced slip into the pipe trench in place.

3. When connecting the pipeline, first determine the placement position of the silicone ring and the depth of the socket. After cleaning the inner cavity of the socket connection of the double-wall corrugated hdpe water supply pipe, wipe lubricating liquid on the inner cavity of the socket connection and the silicone ring of the socket. After the branch pipe is connected, the height and center line of the pipeline shall be met.

4, the deformation modulus of backfilling depends to a certain extent on the deformation and bearing capacity of the double-wall corrugated hdpe water supply pipe, so that the main importance of the success and failure of the pipe network project, strictly control.

5, rain period or underground water level is higher than the top of the pipe area will also produce double-wall corrugated pipe floating situation, must do a good job of trench drainage pipeline, immediately backfill and compaction, if necessary, use non-woven geotextile protection and other measures. In cold areas, the double-wall corrugated hdpe water supply pipe must be buried deep under the cool soil.

How to judge the quality of double wall corrugated hdpe water supply pipe

1. Application of pipelines: For the double-wall corrugated hdpe water supply pipes that are often purchased, different products should be determined according to their usefulness.

2. check the commodity performance: considering the matching level, test level, technical level, after-sale maintenance service, internal work and overall treatment level of the double-wall corrugated hdpe water supply pipe.

3, pipeline manufacturers: select manufacturers with good reputation and market share in the industry.

4. Check the quality of double-wall corrugated hdpe water supply pipe: Check whether the planed surface of double-wall corrugated hdpe water supply pipe is honeycomb-shaped, and there is no embedded explanation. The pipeline can produce and manufacture mixture materials, but all kinds of data information of mixture materials are not closed. Melting was found for a specific time during the electrical welding of the joint.

Advantages:

1. The structure is different, with high compression strength, impact resistance, ring softness, smooth inner cavity and small friction resistance. Pipe fittings of the same diameter can pass through relatively large platform flow. Socket interface, rigid connection, convenient connection, high stability and not easy to leak.

2, light weight, convenient construction, reduce costs.

3, buried use period of more than 50 years.

4. High-pressure polyethylene belongs to vacuum hydrocarbon polymer, its molecular structure is non-polar and corrosion-resistant.

5. The raw materials are green energy-saving materials, non-toxic, non-etching, non-fouling, and recyclable.

6. The available ambient temperature is wide, the pipeline does not crack in the environment of -60 ℃, and the high temperature of the transportation medium is 60 ℃.

7, comprehensive engineering budget cement soil is basically very, low operating costs.
