PVC drainage pipes, with their excellent chemical inertness and stable molecular structure, demonstrate long-lasting and reliable service capabilities in various corrosive environments, making them the preferred material for drainage systems.

The cooling stage is the key step in the transformation of the pipe from a molten state to a solid state, and its cooling rate and temperature gradient need to form a closed loop with the extruder temperature control.

The effective reduction of drainage noise by PVC drainage pipes is not due to a single factor, but rather the result of the combined effects of material physical properties, optimized fluid mechanics, and system engineering design.

If the pipe end faces are not parallel, or the heating plate is not fully welded to the end faces, an incomplete fusion area will be formed, which may lead to internal cracks or potential for further cracking.

High-density polyethylene (HDPE) silicon core tubes, with their unique "low-friction inner wall + multi-hole bundled" composite structure, significantly improve the density of optical cables per unit cross-section, ensuring construction efficiency while g

The rough inner wall easily adsorbs dust, moisture or corrosive substances, forming a localized area of ​​accelerated aging of the insulation layer.
