Description

Technical Field

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

[0002] As core components in water supply and drainage, oil and gas transportation, and industrial pipeline networks, pipe fittings directly determine the safety and service life of the pipeline system through their connection strength and shear resistance. During operation, pipeline systems not only withstand medium pressure but also experience axial tensile and lateral shear forces due to temperature changes, ground settlement, and external impacts. Insufficient fitting strength can easily lead to leaks, fractures, and other accidents, resulting in water waste, environmental pollution, and even safety hazards. Therefore, pipe fittings must undergo rigorous strength testing before leaving the factory. However, traditional testing devices have significant shortcomings in terms of compatibility, testing dimensions, data accuracy, and operational efficiency, making it difficult to meet diverse testing needs.

[0003] Pipeline connectors are subjected to complex stress scenarios in practice, requiring them to meet both axial tensile and lateral shear requirements simultaneously. However, traditional devices can only test performance in one dimension: axial testing devices cannot simulate lateral shear forces, and lateral testing devices lack axial tensile testing capabilities. To complete full performance testing, the connectors need to be transferred between multiple devices, making the operation cumbersome. Therefore, we propose a pipeline connector strength testing device. Utility Model Content
