【Ten Years of Rapid Development in Chemical Engineering Equipment】1630–2023: Development of China’s first claw-type underwater hydraulic connector

Thread Content

Happy May Day 2024! Safety first. Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment. **********************【Ten Years of Great Development in Chemical Engineering Equipment】A continuously updated summary post is available; feel free to participate in the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Engineering Forum) *****************On October 8, 2023, China’s first claw-type underwater wellhead hydraulic connector was shipped from CNPC Baoji Petroleum Machinery Company to the customer’s site, where it is set to undergo sea trials prior to its actual use in projects. The claw-type underwater wellhead hydraulic connector is one of the key devices in offshore oil and gas exploration, primarily used for remote-controlled, rapid connection and disconnection between underwater wellhead units and underwater production trees. To ensure the research, development, and production of the claw-type hydraulic connectors for underwater wellheads, the technical staff at Gemstone Machinery provided support throughout the process, overcoming various manufacturing challenges such as the high-precision processing of the inner and outer surfaces of the cylinder, as well as the processing and assembly of the detachable claws. The claw-type underwater wellhead hydraulic connector is a product ordered by Gem Machinery for a client in China. On September 23, the connector successfully passed a high-pressure gas seal test at 70 megapascals at Gem Machinery, marking the successful development of this product. This adds another new component to Gem Machinery’s range of marine oil and gas equipment, representing a significant step forward in the localization of high-end marine equipment and providing strong technical support for the implementation of related key projects. During the product testing phase, Gem Machinery completed 15 different tests, including hydrostatic pressure tests, locking function tests, combined bending and internal pressure loading tests, and airtightness tests, successfully finishing all of the required testing tasks.
