Problems solved by technology

A common method is to use destructive methods to process standard samples for testing. This method of sampling will lead to the shutdown of oil pipelines, which is contrary to the requirements of life extension operation, causing inconvenience and economic losses. Therefore, the non-destructive / minimal damage method (non-destructive property) Obtaining the mechanical properties of service pipelines has become a key factor in actual testing

Description

technical field [0001] The invention relates to a non-destructive / micro-destructive detection technology for mechanical properties of materials, in particular to a portable in-service pipeline mechanical property detection device. Background technique [0002] In recent years, some domestic scholars have carried out relevant research on continuous ball indentation experiments, but most of them rely on foreign commercial products, and mainly focus on laboratory research. Independent research and development of equipment. However, foreign countries have launched a variety of indentation equipment used in different scenarios and materials. China is in a very passive position in this regard, which seriously hinders the development of non-destructive / micro-destructive testing of related mechanical properties in my country. [0003] The safety of the mechanical properties of oil pipelines in service is of great importance. Due to the complex distribution of pipelines, different d...
