The interior of a car and its environment are very complex, and the wiring harnesses may suffer from various mechanical damages:
Friction and wear: During the installation and operation of the wiring harness, it will come into contact and rub against the body sheet metal and other components (such as the engine and door hinges). The wear-resistant property of corrugated pipes can prevent the insulation layer of wires from being worn through and avoid short circuits.
Compression and impact: During maintenance or minor collisions, corrugated tubes can provide cushioning to prevent the wire harness from being flattened or damaged. Tuoyan, a professional manufacturer.
Cutting and scratching: During assembly on the production line or later installation of equipment, sharp metal edges may cut the wire harness. The corrugated pipe forms the first physical barrier.
The types of corrugated pipe materials
To meet the demands of different regions, corrugated pipes of various materials are used in automobiles:
PP (Tuoyan Polypropylene) corrugated pipe: Low cost, good flexibility, mainly used in dry and low-temperature areas such as the interior of vehicle bodies.
PA (Tuoyan Nylon) corrugated pipe: It is the most commonly used type. It has excellent wear resistance, oil resistance, high-temperature resistance and flame retardancy, with outstanding comprehensive performance, and is widely used in harsh environments such as engine compartments and chassis.
PE (Tuoyan Polyethylene) corrugated pipe: It has good low-temperature resistance, but poor high-temperature resistance.
Open-type corrugated pipe: There is an opening on the side, which can be directly clamped onto the already installed wiring harness, facilitating the installation of additional lines or maintenance in the future without the need to disconnect and re-thread the wiring harness joints.
