Domestic first!

The mountain welding process and flexible mountain automatic welding equipment developed by the Research Institute of China Petroleum Pipeline Bureau Engineering Co.
, Ltd.
(referred to as the Pipeline Bureau) were successfully applied in the Zaoyang-Xantao section of the Middle Section of the Third West-East Gas Pipeline (Zhongwei-Jian) ​​project
.
The equipment realizes 25-degree uphill and downhill movement, grouping, and welding.
Its successful application marks another breakthrough in the automation of mountain pipeline construction by domestic automatic welding machines and welding technology, which is the first in China
.

The relevant person in charge said that, as the main force in the construction of national energy storage and transportation facilities, the Pipeline Bureau has vigorously implemented innovation strategies for many years, paid close attention to the research and development of key core technology and equipment, strengthened the deep integration of scientific research, design and construction, and took improving industrial quality as the mission of the times to make breakthroughs.
It has developed a key technology, created one "domestic initiative" and "international leader", and filled a "industry gap"
.

"The third-generation automatic pipeline welding adopts a fully digital control system, and the core components have achieved national production, and can collect more data in an all-round way through external sensing equipment or systems, providing a data basis for building a smart pipe network
.
" According to the person, combined with the research and development experience of CPP900 automatic welding equipment, the Pipeline Bureau has accelerated the exploration of the third-generation automatic pipeline welding equipment.
At present, the equipment development and on-site application have been successfully completed, marking that the domestic automatic welding equipment has entered the international advanced ranks
.
Among them, the self-developed third-generation CPP900 automatic welding, automatic ultrasonic testing (AUT) equipment, mechanized joint repair technology and equipment and other core technical equipment with independent intellectual property rights, continuous breakthroughs and continuous upgrades, effectively solving engineering construction problems , seized the commanding heights of the industry
.

With the development of long-distance pipeline welding technology, pipeline inspection technology is also improving
.
In order to fill the technological gap in our country and develop high-tech with independent intellectual property rights, the Pipeline Bureau established a phased array ultrasonic focusing calculation model to achieve precise control of ultrasonic sound beams, breaking the international technological monopoly in the research and development of non-destructive testing technology
.
The self-developed new generation of AUT testing equipment has passed the -30 ℃ low temperature test, and has completely replaced imported products in the construction of many domestic pipeline projects, reaching the international advanced level of similar products
.

The relevant person in charge said that now the Pipeline Bureau insists on deploying the innovation chain around the industrial chain, relying on the innovation chain to enhance the value chain, and has built a structure ranging from planning, scientific research, consulting, survey, design, procurement, construction, machinery manufacturing to production and operation, maintenance and technology.
The guaranteed complete industrial chain has promoted the technological development of China's oil and gas pipeline construction industry
.

It is understood that the Pipeline Bureau has the only domestic long-distance pipeline engineering survey and design consulting professional design institute and the only national engineering research center for oil and gas pipeline transportation safety in the domestic pipeline industry
.
After years of exploration and practice, he has also mastered the design, construction, inspection and repair of onshore and marine pipelines, hydrogen and natural gas hydrogen-mixed pipelines, large liquid hydrogen storage tanks, oil and gas storage tanks, carbon dioxide gathering and transportation, storage, and supercritical pipelines.
Design and construction, design and installation of pipeline communication and automation control systems, construction of large pipelines in complex areas and manufacturing of supporting equipment, design and construction of liquefied natural gas purification, liquefaction, storage, and receiving stations, design and installation of oilfield surface gathering and transportation and refining and chemical equipment and other core technologies
.
Since the "Thirteenth Five-Year Plan", 343 scientific research projects have been carried out, with a cumulative R&D investment of over 520 million yuan, 668 authorized patents, 95 construction methods, and a cumulative promotion of more than 130 scientific research achievements
