A new generation of automatic welding large-diameter beveling machine has been successfully developed recently, China Stone & EU believes that the above primary plastic products constitute 70% of the source of marine garbage. The oil and natural gas pipeline bureau has successfully developed a new generation of automatic welding equipment cpp900-1422 large-diameter beveling machine. The main indicators of this technology are similar to the world's most advanced American CRC. Its characteristics are that it can achieve high load, high frequency and low consumption equipment, and the cost is only 60% of that of CRC. It is reported that at present, the pipeline bureau has started the technical research representing the development trend of the industry in the next few years or even more, and proposed the goal of building a "digital, information, intelligent and efficient" pipeline, introducing relevant cutting-edge technologies into the field of pipeline construction, which will lead to another leap in China's pipeline construction technology

China Petroleum Pipeline administration has successfully developed a new generation of fully automatic welding equipment cpp900-1422 large caliber beveling machine. The main technical indicators of this technology are equivalent to the world's most advanced American CRC equipment, and the cost is only 60% of that of CRC

cpp900-1422 large-diameter beveling machine was seen in the National Engineering Laboratory for oil and gas pipeline transportation safety of China Petroleum Pipeline administration in Langfang, Hebei Province. This machine can perform beveling operations for 1422mm diameter pipelines. The designer Zhang Feng showed the work of the beveling machine for the production of aluminum alloy medium and thick plates in the first production line. In less than 2 minutes, this machine weighing several tons completed the single port beveling of a steel pipe. The field measurement data shows that the groove size error is less than 0.1mm, and the flatness error is less than 0.05mm

it is understood that cpp900 is only a representative of the high-tech products of the pipeline bureau. After more than 40 years of development, the pipeline bureau has built more than 80000 kilometers of pipelines at home and abroad, with a total mileage of two circles around the earth. Since the 12th Five Year Plan, the pipeline bureau has carried out 265 major scientific and technological breakthroughs, obtained 399 authorized patents and 25 awards at or above the provincial and ministerial levels. The Bureau has achieved self ownership of core technologies, localization of key equipment and mechanization of operation methods, and mastered high-end technologies covering the whole industry chain of pipeline engineering, such as design, construction, inspection, maintenance and emergency repair, production and operation

these high-end technologies have effectively improved the overall construction level of China's oil pipelines. When building the Myanmar China oil and gas pipeline, one of the four major national energy strategic channels, the pipeline bureau adopted the design method and standard of pipeline parallel laying spacing, which saved the country 2.5 billion yuan of investment and reduced the land occupation of 14300 mu; For the first time, the west section of the west east gas pipeline 3 adopted 0.8 design coefficient and corresponding construction technology to save energy and materials, leading China's pipeline industry to establish a new standard; The large-scale application of fully automatic welding equipment and mechanized liquid polyurethane joint coating technology in the west section of west east gas pipeline 3 has effectively improved the project quality; The cross platform oil and gas pipeline SCADA system software is applicable to large oil and gas dispatching center and station control system at the same time, breaking the foreign monopoly and successfully applied to Tanzania National Natural Gas Pipeline Project

since 2011, the pipeline bureau has started to carry out in-depth research on the "pipeline life cycle" technology. At present, it has realized the transformation of achievements, which has been successfully applied to the construction of Harbin Shenyang Railway and Tiefu railway, and will be fully applied in the middle section of the west east gas pipeline 3. Meanwhile, the optical fiber pipeline safety early warning system, high-definition magnetic flux leakage detector, large-diameter hot bends and other equipment independently developed by the pipeline bureau are also used in the pipeline under construction or operation

It is reported that the pipeline administration has started the technical research representing the development trend of the industry in the next few years or even more, including X90/X100 high-grade steel pipelines, the bottleneck technology applied by non-metallic pipes in the field of long-distance oil and gas pipelines, and the internal defect detection technology of offshore pipelines, It also puts forward the goal of "digitalization, informatization, intelligence and efficiency" pipeline construction, and introduces relevant cutting-edge technologies into the field of pipeline construction, which will hasten another leap in China's pipeline construction technology.
