Show the international level! Changshengda Steel pipe deep water with high quality sea pipe project successfully passed acceptance

Recently, Changshengda Steel Pipe deep water with high-quality offshore pipe project ushered in the review of top professors from famous domestic schools and authoritative experts in the oil and gas industry, the experts unanimously evaluated level. Among them, the results of the "Localization and application of kilometer deep sea large size corrosion resistant and easy welding seamless pipe for long distance transportation pipeline" have reached the international leading level of full-length full-circumference performance uniformity and pipe end size control technology.

The Phase I development project of Bozhong 19-6 Gas field, the first 100 billion cubic meter gas field in Bohai Sea, has been successfully put into operation, marking a new stage in the development of deep complex buried hill hydrocarbon reservoirs in China. The project uses high-end pipeline products independently designed and produced by Tianjin Steel Pipe.

The non-standard steel grade X85Q high-strength offshore structural pipe developed by Jinzheng Steel Pipe achieved its first delivery, setting a record of the highest steel grade of non-standard pipeline pipe products exported by the company.

In the Lingshui Sea area of Hainan, China's longest deep-water oil and gas pipeline, the key control project of the second phase of the "deep-water No. 1" ultra-deep-water gas field - a 20-inch submarine long-haul pipeline with a total length of 115.5 kilometers was completed. In the deep sea of nearly 1,000 meters, the 9,425 seamless sea pipes with the largest diameter in China provided by Changshengda Steel Pipe provide a hard core guarantee for China's ultra-deep water oil and gas development equipment technology.

Deep-sea long distance, large pipe diameter, high strength, corrosion resistance and high pressure transportation are gradually becoming the development direction of onshore and offshore long distance oil and gas pipelines. Compared with the onshore pipe, the requirements of the Marine environment application in the use of pipe type, dimensional accuracy, length and comprehensive performance are higher than that of ordinary pipes.

Changshengda Steel Pipe deep water with high quality pipe project is around the global deep sea energy development urgently needed to tackle the key production technology of high-quality pipes, to achieve full length and full circumferential performance of all one-time qualified steel pipe performance, showing excellent strength and toughness, corrosion resistance and high weldability verified by field construction, to solve the deep sea oil and gas field development seamless steel pipe "jam neck" problem.
