It is precisely because HDPE double-wall corrugated pipe has the above excellent features that it can adapt to many application environments. For different projects, HDPE double-wall corrugated pipes are made into different specifications.

HDPE double wall corrugated pipe process:

  • Digital centralized control across the board

  • Double-machine co-extrusion, double-layer diversion

  • Full vacuum belt feeding

  • Random flaring once molding

What kind of specification is HDPE double wall corrugated pipe? The general process is like this.

HDPE double wall corrugated pipe performance:

  •  Strong resistance to external pressure

The outer wall has a ring-shaped corrugated structure, which greatly enhances the ring stiffness of the pipe, thereby enhancing the resistance of the pipe to soil load. In this performance, the HDPE double-wall corrugated pipe has obvious advantages compared with other pipes.

  • HDPE double-wall corrugated pipelow engineering cost

Under the condition of equal load, HDPE double-wall corrugated pipe only needs thinner pipe wall to meet the requirements. Therefore, compared with the solid-wall pipe of the same material and specification, it can save about half of the raw materials, so the cost of the HDPE double-wall corrugated pipe is also lower. This is another very prominent feature of the pipe.

Due to the light weight of the HDPE double-wall corrugated pipe, the handling and connection are very convenient, so the construction is fast and the maintenance work is simple. Tight schedule and construction

In the case of poor conditions, its advantages are even more obvious.

  • HDPE double-wall corrugated pipe has Small friction coefficient, large flow

The HDPE double-wall corrugated pipe made of HDPE can pass a larger flow than other pipes of the same diameter. In other words, under the same flow requirements, HDPE double-wall corrugated pipes with relatively small diameters can be used.

  • HDPE double-wall corrugated pipe has  Good low temperature resistance and impact resistance

The embrittlement temperature of HDPE double-wall corrugated pipe is -70℃. Generally, it is not necessary to take special protective measures during construction under low temperature conditions (above -30 °C), and the construction in winter is convenient. Moreover, HDPE double-wall corrugated pipes have good impact resistance.

  •  HDPE double-wall corrugated pipe has good chemical stability

Since HDPE molecules are not polar, they are chemically stable. Except for a few strong oxidants, most chemical media have no destructive effect on it. In general, the soil, electricity, and acid-base factors of the environment will not damage the pipeline, breed bacteria, and scale, and its flow area will not decrease with the increase of operating time.

  • HDPE double-wall corrugated pipe has long lasting

The service life of HDPE double-wall corrugated pipes can reach more than 50 years under the condition of being protected from sunlight and ultraviolet rays.

  • Excellent wear resistance

Germany has used tests to prove that the wear resistance of HDPE is even several times higher than that of steel pipes.

  • HDPE double-wall corrugated pipe has proper deflection

A certain length of HDPE double-wall corrugated pipe can be slightly deflected in the axial direction, not affected by a certain degree of uneven settlement on the ground, and can be directly laid in a slightly uneven groove without pipe fittings.

Specifications of HDPE double wall corrugated pipe:

HDPE double-wall corrugated pipe has complete specifications, the diameter is from DN200-DN600, and the ring stiffness of HDPE double-wall corrugated pipe is sn4 and sn8 respectively.

Application scope of HDPE double wall corrugated pipe:

It is precisely because these are the specifications and low prices of HDPE double-wall corrugated pipes that HDPE corrugated pipes have the following application scenarios.

  1. Municipal drainage and sewage pipeline system engineering;

  2. Drainage and sewage are buried underground in apartments and residential quarters;

  3. Pre-buried pipelines of expressways, underground water seepage network of golf courses;

  4. Water conservancy projects such as farmland water conservancy irrigation, water supply and drainage;

  5. Chemical industry and mine are used for fluid transportation and ventilation, etc.;

  6. Protective casing of underground pipelines and communication cable casings, etc.

Storage method of HDPE double wall corrugated pipe:

HDPE double-wall corrugated pipes should be stored in a dry warehouse at room temperature. Straight pipes should be laid flat, and the stacking height should not exceed 2 m. Disassembled and coiled porous tubes can be laid flat, but should avoid heavy pressure or compression stacking.

HDPE double-wall corrugated pipes are not allowed to be mixed with toxic and harmful substances, and should be kept away from heat sources. A striking fire prohibition sign should be set up in the storage place.

The storage period shall generally not exceed 2 years from the date of production.

The storage method of HDPE double-wall corrugated pipe has little to do with the specification, because the corrugated pipe of any specification must be stored according to the regulations.

HDPE double wall corrugated pipe installation instructions:

  • HDPE double wall corrugated pipe must be purchased according to the specifications adapted to the project.

  • HDPE double-wall corrugated pipe installation must be performed by qualified personnel.

  • When handling the material, it is strictly forbidden to throw, drop, roll and drag to avoid damage to the pipe. When connecting the pipe, check both ends. If there is any damage, please cut off the damaged part.

  • Hot melt connection of pipes and fittings. The welding temperature should be set at 260±10. If there is any discoloration decomposition, burning, smoke or other adverse effects, please replace the welding machine.

  • Although the threaded fittings are connected to other parts, be sure not to over-tighten them to avoid damaging the threaded fittings.

  • Please strictly follow the arrangement and business standards of HDPE double-wall corrugated pipes to ensure the quality.

  • After the installation is completed, a water pressure test must be carried out to confirm that there is no leakage, and then the pipe channel can be closed or filled. The test pressure should be 1.5 times the design pressure. The recommended test pressure is 10kg/cm2 (MPa)-15 kg /cm2 (pressure 1.5MPa).

  • Although the transition connection with water heater, metal pipe or hose connection pipe is advisable, its length should not be less than 300mm.

  • Outdoor piping should be considered to have thermal insulation, sun protection and freeze protection measures.

  • In winter, when the temperature is close to 5, the accidental damage of pipes and fittings can be prevented during handling and construction. After the pressure test is completed, the water is discharged. For long-term shutdowns in winter, the water in the pipes is not reliable. Insulation measures to prevent pipe cracks.

  • While carrying out waterproofing works, do not apply paint, asphalt and other polluted materials on the surface of the pipes, so as to avoid the smell of water.
