The Yingmaili to Sancha and Lunnan to Shangku Industrial Park sections of the PetroChina Tarim Oilfield Gasification South Xinjiang Natural Gas Pipeline Project have recently started construction simultaneously. The two 510 kilometer long "Steel Gas Dragons" will extend along the southern foothills of the Tianshan Mountains, bringing clean natural gas energy to the southern Xinjiang region. This project is an important component of the natural gas pipeline expansion project in northern and southern Xinjiang, and is also a major energy project that benefits people's livelihoods.
Among them, the western Yingmaili to Sancha pipeline has a total length of 382 kilometers and a daily gas supply capacity of 7.2 million cubic meters; The pipeline from Lunnan on the east side to Shangku Industrial Park is 128 kilometers long, with a daily gas supply capacity of 20.4 million cubic meters. It is planned to be fully connected and put into operation before November 30, 2025. The pipeline passes through more than 300 complex sections such as railways, highways, and rivers. The construction unit has invested more than 20 units and over a thousand construction personnel to advance the river crossing construction during the dry season. After the completion of the project, it will achieve dual line gas supply, greatly improving the gas supply guarantee capacity in southern Xinjiang and benefiting people of all ethnic groups in Bazhou, Kashgar, Aksu and other places.
The Xinjiang Oilfield Emergency Rescue Center has recently successfully completed the dredging task of the first 425 meter section of the DN300 sewage pipeline in Oil Production Plant 1. For the first time, continuous tubing technology has been applied to the unblocking of long-distance sewage pipelines, achieving a technological breakthrough in this field in China. The total length of the pipeline constructed this time exceeds 4642 meters. Due to the long-term transportation of sewage, the internal scaling is severe, and the rated pressure of the pipeline is only 2.6 megapascals, making it extremely difficult to clear.
The technical team determines key parameters such as the inlet angle of the continuous oil pipe through precise calculation, adopts the "segmented drag washing" process to avoid secondary accumulation of scale and debris, and selects special working media to prevent winter freezing and blockage risks. At the same time, a rotating jet unblocking tool is introduced to solve the problem of debris suspension through the dual action of hydraulic jet and mechanical rotation, and real-time monitoring of pressure changes throughout the process ensures operational safety. This technological breakthrough has significantly improved the efficiency and accuracy of unblocking long-distance sewage pipelines, forming replicable and promotable construction experience, and providing solid technical support for safe production in oil and gas fields.
Under the guidance of the "dual carbon" goal, Hebei Baoji Pipeline Manufacturing Co., Ltd. has launched a new generation of low-carbon and environmentally friendly petroleum pipe series. Through material formula optimization and production process upgrading, the company has achieved a reduction of over 15% in carbon emissions throughout the product lifecycle. The related technology has obtained three national invention patents. This series of pipes adopts new alloy materials and energy-saving processing technology, which significantly improves resource utilization and reduces energy consumption and pollutant emissions in the production process while maintaining the high-strength characteristics of traditional materials such as J55 and Q125. The low-carbon pipes launched this time cover a full range of products such as oil casing and tubing, with specifications ranging from Φ 33.4mm to Φ 762mm. They can be widely used in onshore oil fields, shale gas development, and other fields. The company also synchronously builds an intelligent energy consumption monitoring platform to achieve refined energy-saving management in the production process. At present, the low-carbon pipe has been successfully applied in a large-scale shale gas green development project in China, and has gained market recognition for its stable performance and environmental advantages. Hebei Baoji Pipeline stated that it will continue to promote technological innovation, create more low-carbon and efficient pipeline products, and help the sustainable development of the energy industry.
Relying on the opportunity of deepening the energy cooperation of the "the Belt and Road", Hebei Baoji Pipeline Manufacturing Co., Ltd. recently announced that its Φ 406mm - Φ 762mm large diameter oil casing has passed the certification of the Central Asia Natural Gas Pipeline Project, officially becoming one of the core pipe suppliers of the cross-border energy project. The selected pipes cover multiple buckle types such as BTC and STC, and are made of high-strength materials such as N80 and C110, which can adapt to extreme climate and complex geological environments in Central Asia and meet the dual international standards of API 5CT and ISO 11960.
The company has established a rigorous quality control system from raw material screening to finished product delivery by introducing internationally advanced full process testing equipment, ensuring the sealing performance and durability of pipes under high pressure and low temperature conditions. It is reported that this batch of pipes will mainly be used in the expansion project of the Central Asian natural gas pipeline, helping to improve cross-border gas transmission capacity. It is expected that the annual transmission volume will increase by 5 billion cubic meters. The person in charge of Hebei Baoji Pipeline stated that they will continue to deepen their involvement in cross-border energy projects and provide customized pipeline system solutions in the future.
Recently, the intelligent welding matching pipe material independently developed by Hebei Baoji Pipeline Manufacturing Co., Ltd. has been successfully applied in the oil and gas pipeline project in the southwestern mountainous area. With its structural design that adapts to steep terrain and high-strength material characteristics, it greatly improves the construction efficiency under complex geological conditions. This batch of pipes is made of high-strength steel materials such as L80 and P110, strictly following the API 5CT standard, and equipped with a fully automatic welding robot system, achieving a one-time pass rate of over 98% for welds, and improving construction efficiency by 3-4 times compared to traditional processes. As a backbone enterprise of the "China Pipeline Equipment Manufacturing Base", the company optimizes the accuracy and fatigue resistance of pipe interfaces to address the difficulties in pipeline construction in mountainous areas, and provides full process services from product customization to welding guidance. The pipes used in this application not only solve the industry pain point of unstable weld formation in steep terrain, but also reduce more than 60% of carbon emissions during the construction process through environmentally friendly material formulas, achieving a dual breakthrough in engineering efficiency and green construction. At present, this series of products has been promoted and applied in multiple mountain energy channel projects in China.
Hebei Baoji Pipeline Manufacturing Co., Ltd., rooted in the "China Pipeline Equipment Manufacturing Base", has recently successfully served large-scale shale gas development projects and cross-border oil and gas transportation projects in Central Asia with a full range of high-performance petroleum pipes, providing strong support for global energy infrastructure construction.
As a professional petroleum pipe manufacturing enterprise, the company has established a full specification processing system from Φ 33.4mm to Φ 762mm, mainly engaged in petroleum casing, tubing and other products, covering multiple buckle types and high-strength materials.
