On April 20th, the national 863 marine drilling riser joints E and H were tested on a 2041-ton static load tester of Baoji Petroleum Machinery Co., Ltd. The test was completed by a 10-grade tensile test. E-type maximum load 912 tons to meet the 2000 meters water depth conditions, H-type maximum load of 1589 tons to meet the 3000 meters water depth conditions.

Drilling riser joints are one of the key components of offshore drilling riser systems. They have many uses such as connecting riser strings, fixed auxiliary pipelines, high pressure drilling fluid inside and outside the isolation pipes, and seawater. Their technologies and products have been monopolized by developed countries in Europe and America. . The first offshore drilling riser device and related components developed by Baoji Petroleum Machinery Co., Ltd. have broken the monopoly of foreign countries and is of great significance in promoting the localization of high-end petroleum equipment.

It is reported that during the "12th Five-Year Plan" period, China's investment in marine engineering construction will reach 250 billion to 300 billion yuan, and the offshore oil equipment market will have broad prospects.
