Quick opening blind plate has been achieved domestically, learned from the machinery company China Petroleum Pipeline Bureau, with completely independent intellectual property rights of high sulfur, high carbon, high pressure and quickly opening blind plate batch factory in this company. This indicates that the fast opening blind plate of high sulfur oil and gas fields in our country has been made in China.

This is following the June Pipeline Bureau Machinery Company for Jiangsu LNG pipeline engineering and manufacturing of 1200 mm diameter, 10.5 MPa pressure of large diameter high pressure quick opening blind plate success after leaving the factory, as a category of large diameter and high pressure of Puguang gas field development quick opening blind plate.

Large aperture high pressure fast opening blind plate is the core component of high pressure pipeline equipment in China. Prior to 2009, the domestic pipeline with fast opening blind plate 95% rely on imports, large diameter high pressure fast opening blind plate is 100% rely on imports.

Fast opening blind plate as the key equipment of the ground gathering and long-distance transmission pipeline engineering, its high pressure resistance, corrosion resistance and the ability to quickly open the function requirements, determine the product has a high technical requirements. In order to ensure the construction of China's oil field gathering and transportation and pipeline key projects, Pipeline Bureau machinery company to play pipeline equipment manufacturing and research and development advantages, to achieve a high pressure and large diameter fast opening blind plate and a series of high-end products.

Developed by machinery company of China Petroleum Pipeline Bureau, the largest diameter, the highest pressure quick opening blind plate and the insulating joint - pressure of 12.6 MPa, 1550 mm diameter ring lock type fast opening blind plate and a pressure of 12 MPa, 1400 mm diameter integral insulating joint, recently by the detection of China special equipment inspection and research institute. This marks China's oil and gas pipeline key equipment made a new breakthrough in china.

According to the Bureau of pipeline machinery company manager Mu Duo introduced, quick opening blind plate and insulation joint is a major research topic in petroleum science and technology special "localization" of oil and gas pipeline of key equipment and "the third generation high throughput natural gas pipeline project" the key technology research. Design of the two products, is to further enhance the pipeline bureau of high pressure, large diameter quick opening blind plate and the insulating joint technology, not only ready for the North Tianshan standby channel construction, at the same time as the main line Chinese pipeline construction fast opening blind plate localization and the third generation of large volume of natural gas pipeline construction the technology preparation.

In the face of a new round of pipeline construction pipeline bureau peak, the new leadership adhere to Scientific Outlook on Development as a guide, on the one hand take the initiative to assume security responsibility, for a global force, overcome difficulties, to promote the construction of key projects, ensure the quality and safety, build a national strategic channel; on the other hand, seize the opportunity to study and practice activities of Scientific Outlook on Development. Focus on the full of wisdom, clarify the development of ideas, adjust management system, optimize business structure, achieved remarkable results in the transformation of development mode.
