Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of detection devices, more particularly, to a PVC pipeline service life detection equipment. BACKGROUND

[0002] In the actual application scenarios of PVC pipelines, such as water supply and drainage systems, chemical fluid transportation, and other fields, accurate assessment of the service life is crucial to ensure the long-term stable operation of the project. However, the current detection methods for PVC pipeline service life have many limitations, making it difficult to comprehensively and accurately reflect the real condition of the pipeline during actual use.

[0003] Currently, most PVC pipeline service life detection focuses on tensile testing of the pipeline, which preliminarily assesses its performance by judging the degree of fracture during the tensile process. However, this detection method has great one-sidedness. On the one hand, relying solely on tensile testing can only understand the strength performance of the pipeline under a single stress mode, and cannot fully reveal the aging state of the PVC pipeline in the actual use environment. During the long-term use of PVC pipelines, they are affected by various factors such as ultraviolet radiation, chemical substance corrosion, temperature changes, and other factors, which gradually change the internal molecular structure, leading to performance aging. These aging characteristics cannot be accurately reflected by simple tensile fracture degree judgment, often requiring manual detection with other complex methods, which not only consumes time and effort, but also makes the detection results susceptible to human factors, lacking objectivity and accuracy.

[0004] On the other hand, the existing detection methods generally have the problem of insufficient simulation of actual use conditions. In real-world applications, PVC pipelines are mostly used to transport various liquids, and the inside bears a certain liquid pressure. However, the current detection is usually simply tensile testing of the pipeline, without considering the influence of internal liquid pressure on the aging stress state of the pipeline. In fact, internal liquid pressure changes the stress distribution of the pipeline, accelerating the aging process of the pipeline. Therefore, the lack of simulation of such actual working conditions in detection makes the experimental results relatively single, and cannot truly reflect the service life of the PVC pipeline in actual use. Based on such experimental results, the decisions made may lead to inaccurate estimation of the service life of the pipeline in engineering design, thereby causing problems such as premature rupture and leakage of the pipeline, which not only causes economic losses, but also poses a threat to environmental and personnel safety.

[0005] In summary, the existing PVC pipeline life detection method is difficult to meet the demand of modern engineering for accurate evaluation of PVC pipeline life due to single detection dimension, lack of actual working condition simulation and other problems. It is urgent to develop a comprehensive and accurate detection device that can consider various aging factors and simulate the actual internal liquid pressure state, which is of great significance to improve engineering quality, ensure public safety and promote the progress of related industry technology.
