Plastic Outer Sleeves for Round Pipes are versatile accessories widely applied in construction, home appliances, industrial machinery, and daily life, thanks to their functions of protection, connection, and safety enhancement. Their lightweight, corrosion-resistant, and cost-effective properties make them indispensable in multiple fields.
In the construction industry, these sleeves are mainly used for protecting metal and plastic water supply/drainage pipes. For example, in building basements or underground pipe networks, metal round pipes are prone to corrosion from soil moisture and chemicals. Covering them with PVC or PP plastic outer sleeves isolates the pipes from the harsh environment, extending their service life by 30% on average. Besides, at the joints of indoor decorative pipes (such as ceiling exhaust pipes), the sleeves act as transition parts. They cover the uneven joint gaps, improving the overall aesthetics while preventing dust accumulation in the gaps.
In household appliances, the sleeves play a key role in safe operation and noise reduction. In washing machines and dishwashers, the water inlet and outlet round pipes often rub against the machine shell during use. Installing plastic outer sleeves on the pipe sections in contact with the shell reduces friction, avoiding pipe wear and minimizing operating noise. For electric water heaters, the sleeves are used on the outer surface of hot water outlet pipes. Made of heat-resistant plastic (like PPS), they prevent users from accidental scalding when touching the pipes, enhancing safety.
In industrial machinery, the sleeves are applied to round pipes in transmission systems. For instance, in conveyor belt equipment of factories, the round pipes that support the belt are exposed to dust and debris. The plastic outer sleeves form a protective layer, preventing impurities from adhering to the pipe surface and ensuring smooth belt operation. Additionally, in mechanical cooling systems, when connecting two round pipes of similar diameters, the sleeves serve as auxiliary connectors. They align the pipes accurately and reduce wear at the connection, ensuring stable coolant circulation.
In daily life, the sleeves are common in furniture and fitness equipment. In adjustable desks with round support pipes, the sleeves are installed at the pipe adjustment joints. They not only fix the pipe position but also avoid scratches on the pipe surface during adjustment. In fitness machines like dumbbell racks with round guide pipes, the sleeves reduce noise when the dumbbell brackets slide along the pipes, providing a quieter user experience.
