When making mechanical connections, bolts must be tightened according to the torque value recommended by the manufacturer to avoid leakage due to excessive looseness or damage to the threads due to excessive tightness.

MPP power cable protection tubes, with their excellent high-temperature resistance, external pressure resistance, and insulation properties, have become the preferred material for laying medium and low voltage cables below 10kV.

In the crisscrossing "neural network" of urban underground infrastructure, communication optical cables, power cables, and low-voltage systems act like the city's blood vessels, silently supporting information flow and energy supply.

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.
