Meets the deep-sea oil and gas development

<

[China Instrument Network Instrument R&D] According to Shanghai Pudong Hanwei Valve Co., Ltd., the company's domestic underwater valve application feasibility in the Wenchang 9-2/9-3/10-3 gas field development project was approved by China National Offshore Oil Corporation. The experts of the “New Sanhua” Leading Group recognized that this was a historic breakthrough for domestic underwater valves.

Exploitation of oil and gas in the deep sea is the development trend of future resource development. At present, major companies in the world are aiming to have an avatar in the ocean. The underwater valve is one of the important equipments for deep sea development. Currently, there are not many companies that can produce underwater valves in the world, and well known companies include Cameron, FMC, Tyco, etc., all of which are overseas companies. Underwater valves are monopolized by foreign manufacturers, which will greatly increase the cost of China's deep-sea development, and the localization of underwater valves is a must.

It is reported that Shanghai Pudong Hanwei Valve Co., Ltd., a subsidiary of China Valve Science and Technology Holdings Co., Ltd., has already joined experts from various universities such as Zhejiang University to open research and development of domestic underwater valves. In February of this year, Shanghai Hanwei was invited by the CNOOC Wenchang project team to participate in the underwater valve development project. As of August 15, Shanghai Hanwei completed all the work for the localization of underwater ball valves for the Wenchang 9-2/9-3/10-3 gas field development project, and it was successfully obtained by the American API Association before the completion of the mission. The API6DSS certificate issued, which is the second company in China to obtain this certification.

At the beginning of September, at the Feasibility Review of the Application of Domestic Underwater Valves in the Wenchang Engineering Project, the participating experts reviewed the design, materials, manufacturing, testing, third-party BV certification data and ball valve trial completion documentation of the underwater ball valve, and checked all the completions. After the underwater ball valve was dismantled after testing, it was agreed that the Shanghai Hanwei underwater ball valve product prototype meets the requirements of the Wenchang project and may be included in the bid list.

Chen Weibin, general manager of Hanwei Company, stated that Hanwei will further manage the supplier's management and process of outsourcing of out-of-water valves and outsourcing parts; it will further improve the overall quality system of underwater ball valves and strengthen process quality control; Refine the valve assembly process.
