Green environmental protection: nondestructive testing technology is widely used
In May 8th, from a construction company of China Petroleum Engineering Construction Co., Ltd., the company's research and development of ultrasonic diffraction time difference method (TOFD) pipeline weld technology has been applied to the construction of high pressure thick wall pipeline in China Petroleum North China Petrochemical wax oil hydrogenation unit, and the technology of ultrasonic phased array detection pipeline is more advanced than that of TOFD. It has been applied to the nondestructive testing of pipeline weld in the Lu Ma La and Hafei oilfield in Iraq.
Since 2010, the testing branch has developed 4 testing technologies for TOFD pressure vessels, process pipelines, phased array pressure vessels and process pipelines. The authoritative departments have found that the latter 3 technologies are the first study in China.
