Combined with the technological development trend of products, relying on the support of the company's enterprise innovation platform and the national innovation and research and development industrial policy, Haizhong Hose continues to carry out innovative research and industrialization transformation in the directions of "intelligent", "dynamic", "life extension", "annular detection" and "integrity management".
It has mastered the key technology of design, manufacturing and testing of thermal insulation oil transfer hoses, and realized the localization of 300-meter water depth insulation oil transfer hoses.
Invited Det France Veritas (BV) as a third party to carry out TAC certification, did a large number of raw material tests and prototype tests, the design of the experimental sample pipe of this subject reached a depth of 500 meters, and in 2021 obtained the TAC certificate of BV, Haizhong Hose became the first hose manufacturer in China to obtain this certificate.
Develop an 8 "non adhesive dynamic flexible pipe sample and obtain the BV type approval certificate for dynamic flexible pipes.
Research on the overall plan for manufacturing, testing and certification of dynamic flexible risers, precision manufacturing technology for multi-layer structures and joints of dynamic flexible risers, testing technology for dynamic flexible risers, prototype fatigue testing of dynamic flexible risers, and autonomous testing and certification technology for dynamic flexible risers.
Completed the construction and optimization of the composite hose material laboratory and prototype laboratory, completed the transformation and upgrading of the deepwater dynamic composite hose production line, realized the localization of deepwater dynamic composite hoses, and passed the API certification of the American Petroleum Institute, a third-party organization.
For the first time in China, the underwater integrity monitoring of marine unbonded flexible pipes was carried out, and the scattered light signals were corresponded to the in-situ state of the flexible pipes through data processing, so as to realize the measurement of the deformation, temperature, leakage, annular domain pressure and vibration of the marine unbonded flexible pipes, as well as the early warning and positioning of risk points, and finally realize the full coverage of the in-situ submarine flexible pipelines without interruption of intelligent monitoring.
Based on the theory of optical fiber sensing, an on-line monitoring technology suitable for subsea flexible composite hoses was developed.
