Key points of daily care of lined pipes
Jul 01, 2025
As a widely used conveying system in modern industrial and civil fields, the durability and functionality of lined pipes directly affect production efficiency and safety. However, many users often ignore the importance of daily care, resulting in shortened pipe life or degraded performance. This article will introduce the key points of daily care of lined pipes to help users extend their service life and ensure stable operation.
Regular inspection and cleaning
Daily care of lined pipes first requires regular inspection. The inspection content includes whether there are cracks, wear or corrosion signs on the surface of the pipe, especially at the joints and elbows, which are easily damaged by stress concentration. At the same time, attention should be paid to the integrity of the lining material to ensure that there is no shedding or deformation.
Cleaning work should not be ignored either. Dirt may accumulate inside the pipe due to the residual conveying medium, affecting the flow rate and conveying efficiency. It is recommended to select appropriate cleaning agents and tools for regular cleaning according to the characteristics of the conveying medium. For example, for pipes that convey food or medicines, food-grade cleaning agents should be used to avoid contamination.
Anti-corrosion and anti-rust measures
Anti-corrosion and anti-rust of lined pipes are important links to extend their life. For metal lined pipes, anti-corrosion coatings should be applied regularly to prevent oxidation and rust. For plastic or composite lined pipes, it is necessary to avoid long-term exposure to high temperature or ultraviolet light to prevent material aging.
In addition, the support and fixation of the pipes should also be reasonably designed to avoid damage to the lining layer due to vibration or external force. During installation, it should be ensured that the pipes are evenly stressed to reduce local stress concentration.
Correct use and maintenance
Correct use can significantly reduce the loss of lined pipes. The temperature, pressure and flow rate of the conveying medium should be strictly controlled within the design range to avoid overload operation. For example, high temperature media may cause the lining material to soften, while high pressure may cause rupture.
In terms of maintenance, it is recommended to establish a complete record system to track the use and maintenance history of the pipeline. Once an abnormality is found, such as a decrease in flow or an increase in noise, the cause should be promptly investigated and corresponding measures should be taken.
The daily care of lined pipes needs to start from inspection, cleaning, anti-corrosion to correct use. Only through scientific maintenance management can the long-term stable operation of the pipeline be ensured, saving costs and improving efficiency for the enterprise.
