Mastered the key technologies of designing, manufacturing, and testing insulated oil transportation pipe, and achieved the domestic manufacturing of 300m water depth insulated oil pipe.
Invited Bureau Veritas (BV) as a third party to carry out TAC certification, conducting extensive raw material tests and prototype tests, the experimental sample pipe of this research, achieved a design for water depth of 500m. In 2021, Hizenflex obtained the TAC certificate from BV and became the first domestic pipe manufacturer to obtain such a certificate.
Developed an 8’ non-bonded dynamic flexible pipe prototype and obtained the BV type approval certificate for the dynamic flexible pipe.
Researched the overall scheme of dynamic flexible riser manufacturing and testing certification, precision manufacturing technology of dynamic flexible riser multi-layer structure and joints, dynamic flexible riser testing technology, dynamic flexible riser prototype fatigue test, and dynamic flexible riser self-testing and certification technology.
Completed the construction and optimization of composite pipe material laboratory and prototype laboratory, completed the transformation and upgrading of deep-water dynamic composite pipe production line, realized the localization of deep-water dynamic composite pipe, and passed the third-party certification for the pipeline production base, by the American Petroleum Institute (API).
China's first underwater integrity monitoring of marine non-bonded flexible pipe. Corresponding the scattered light signal to the in-situ state of the pipe through data processing, realizing the measurement of deformation, temperature, leakage, annular domain pressure, and vibration of the marine non-bonded flexible pipe as well as the early warning and positioning of the risk point, and ultimately realizing the full-coverage and uninterrupted intelligent monitoring of the in-situ submarine flexible pipeline.
Based on the fiber optic sensing theory, developed an online monitoring technology applicable to submarine flexible composite pipe
