Description

Technical Field

[0001] This utility model relates to the field of pipeline testing technology, and in particular to a composite insulation pipe strength testing device. Background Technology

[0002] Composite insulated pipes are widely used in numerous fields such as construction and energy transmission due to their excellent thermal insulation performance and certain structural strength. However, in actual use, composite insulated pipes face various complex environmental and mechanical conditions, such as soil pressure, external impact, and thermal stress caused by temperature changes. These factors can all affect the strength of composite insulated pipes. If their strength is insufficient, problems such as cracking and deformation can easily occur, leading not only to a decrease in thermal insulation performance and energy waste, but also potentially causing leakage accidents, posing a serious threat to the environment and safety.

[0003] Therefore, accurate strength testing is crucial during the production and use of composite insulation pipes. Traditional strength testing methods often have limitations, such as complex testing processes and low efficiency. Utility Model Content
