Our company has successfully assembled the standard modular phased array test block and support for Moda oil pipeline, which has a milestone significance in the standardized production of phased array test block in our company.

The Mohe Daqing section of the Sino Russian crude oil pipeline is one of the four strategic oil and gas channels in China. After the completion of the pipeline, 15 million tons of Russian low pour point crude oil can be transported every year. The total length of the pipeline is 926 km, passing through the fragile ecological environment areas such as forests, hills and permafrost, which brings great challenges to the pipeline construction. In order to accurately, quickly and high-quality inspection of pipeline welds, the pipeline inspection company adopts advanced aut phased array detection technology. Due to the long oil pipeline, there are several specifications for the thickness of the pipeline and the welding groove style. According to the requirements of inspection, the corresponding phased array test block is needed to detect the pipeline with different thickness and different welding groove, and each test block is equipped with a 360 degree rotation bracket. This not only increases the load of the vehicle, but also takes up the space of the vehicle, which can not meet the field construction requirements of nondestructive testing.

Moda pipeline project team requires our company to design and develop interchangeable phased array test block support, and only one support is equipped for phased array test block with the same pipe diameter and different wall thickness. Therefore, the company organized relevant personnel from technical, production and quality departments to set up a "standard modular phased array test block and bracket research team". Combined with the requirements of the project team and our accumulated processing experience for many years, we finally overcame the bottleneck problem of standard modular phased array test block and bracket after many days of tests day and night. The new phased array test block and bracket with the same diameter have strong interchangeability, which fully meet the requirements of the project team.
