Recently, the hot spot of carat tube consultation, dry goods must be seen in engineering procurement

[Carat tube core performance adaptation scene combing]

Recently, many engineering procurement consultations have been conducted on the adaptation scenarios of carat pipes. As a high-density polyethylene structural wall hot winding pipe, carat pipes themselves have the characteristics of acid and alkali corrosion resistance, wide ring stiffness coverage, low inner wall roughness, high water transmission efficiency, and long service life. They are suitable for various engineering scenarios such as municipal rainwater and sewage discharge, sponge city water storage and water transfer, industrial sewage discharge, and residential integrated pipe network, especially in areas with complex geological conditions and large buried depths. Compared with traditional pipelines, the anti-settlement and anti-leakage advantages are more obvious.

[Core reference standard for carat tube procurement selection]

The selection process is a high-frequency issue that has been consulted recently. When purchasing, we must first match the corresponding ring stiffness grade according to the buried depth of the project and the underground pressure, so as to avoid the deformation of the pipeline caused by insufficient ring stiffness, or the cost waste caused by blind selection of high grades; secondly, according to the corrosion degree of the conveying medium, confirm the material standard of the inner wall of the pipeline; the interface type can be selected according to the construction conditions. The former has better sealing performance and is suitable for projects with high leakage requirements. When purchasing, do not only use price as the core reference, but check the national standard test report of the product to confirm that the performance parameters meet the engineering requirements.

[Common precautions for carat tube construction]

Many procurement feedback construction links are prone to quality problems other than the product itself. Before construction, it is necessary to confirm the flatness of the groove to avoid sharp stones scratching the pipe wall. During the construction of the electric-hot melt interface, the welding temperature and time should be strictly controlled according to the parameters to avoid leakage caused by virtual welding. When backfilling, choose fine sand or plain soil without sharp impurities, and lay it in layers to avoid local pressure excessive extrusion pipeline deformation. After the construction is completed, a closed water test should be done according to the specifications to confirm that there is no leakage before subsequent construction.

When purchasing carat tubes, it is recommended to check the parameters with the construction technical team in advance. Before purchasing, samples can be used for parameter verification to avoid parameter discrepancies after bulk procurement and reduce unnecessary cost losses.
