Recently, a batch of ultra-long high-performance extruded finned tubes was shipped to Punjab, Pakistan, for the capacity-expansion and retrofitting project of the air-cooled heat exchanger (air-cooler) system. The project site in Punjab sees summer maximum temperatures consistently above 45°C, with plant-site conditions featuring sand-dust and trace corrosive industrial gases. The end-user has selected Chinese-manufactured 15.875 mm extruded finned tubes as the core heat-transfer components for air-cooler renovation. Each supplied tube bundle reaches nearly 17.7 meters in length. The ultra-long tube design reduces the quantity of tube-sheet joints and lowers the risk of heat-exchanger leakage. Thanks to the integrally extruded structure with zero clearance between fins and the base tube, the product delivers excellent resistance to high-temperature, sand-dust and corrosion, maintains long-term stable heat-transfer performance, and is well-suited to the high-temperature desert operating conditions in Pakistan. This project covers the upgrade and renovation of the waste-heat cooling system for a local refinery/petrochemical unit in Punjab, focusing on spare-parts expansion and air-cooled tube-bundle replacement. It also ranks among the 2026 heat-exchange-equipment procurement orders in Pakistan’s petrochemical sector.

On July 28, the extra-large diameter continuous pipe rolling mill project of Hengyang Valin Steel Tube (HYST) was officially commissioned. As the world’s first continuous rolling production line for seamless steel pipes with the largest diameter, the line involved a total investment of 3.07 billion yuan and took 18 months to complete.

In 2026, a vessel named Huayang departed from Tianjin Port, carrying 3,400 tons of anti-corrosion submerged arc welded steel pipes manufactured by Huayang Steel Pipe. The pipe specification is Φ508×7.1mm LSAW with 3PE coating, with a total laying length of approximately 30 kilometers, which will be applied to the construction of Kuwait’s crude oil trunk pipeline project. Oil transmission projects impose stringent requirements on steel pipe quality. Weld seam quality, anti-corrosion structure and dimensional consistency directly affect subsequent construction efficiency and long-term pipeline operational safety. Equipped with state-of-the-art anti-corrosion production lines, Huayang boasts solid advantages in process stability and quality control, fully capable of meeting the technical standards of such large-scale energy projects. Huayang Steel Pipe successfully obtained the official pre-qualification certification to enter the Kuwaiti market in 2025, signifying that its product quality, manufacturing capacity and project delivery system have passed comprehensive audits by Kuwait’s oil and gas industry authorities.

This giant steel structure, over 50 meters long, more than 20 meters wide, nearly 50 meters high and with a total weight exceeding 2,000 tons, marks a landmark achievement for Maoming Zhongli after it systematically mastered core technologies including modular design and integrated manufacturing of large-scale complete ethylene cracking furnaces for the first time. As a major national strategic refining and chemical integration project, the CNOOC Shell Huizhou Phase III Ethylene Project involves a total investment of 48 billion yuan. Upon completion, its total ethylene production capacity will reach 3.8 million t/a, making it the largest single-unit ethylene production base in China. Serving as the core "heart" of the entire facility, the 1.6 million t/a ethylene cracking furnace directly determines the operational efficiency, safety and stability of the whole plant by virtue of its technical standard and manufacturing quality.

The debottlenecking revamp and energy efficiency upgrading project for Fushun Petrochemical’s 800 kt/a ethylene plant has entered its final construction phase. Handover for commissioning is scheduled for the end of June 2026, with formal commissioning and startup by late September. Upon completion, the plant’s annual ethylene capacity will rise from 800,000 tons to 950,000 tons, with a total investment of 2.58 billion yuan. Alongside the ethylene capacity expansion from 800 kt/a to 950 kt/a, a brand-new 200 kt/a solution-process polyethylene plant will be constructed, adopting PetroChina’s first domestically developed proprietary process technology. Auxiliary supporting units including air separation, butadiene extraction and MTBE facilities will also undergo technical upgrading. The project applies a modular "building-block" construction methodology. For instance, the No.9 cracking furnace was fully pre-assembled at a prefabrication yard before being shifted into place as a whole. This construction mode enables revamping works to proceed alongside ongoing plant production without disrupting the normal operation of existing facilities. In addition, domestically manufactured million-ton-class ethylene compressors and proprietary large-scale ethylene technologies developed by China Huanqiu Contracting & Engineering Corporation are deployed for the project.

Location: Maoming, GuangdongInvestment Scale: Approximately 30.5 billion yuan Core Content:This project serves as a benchmark for Sinopec's "reduce oil production, increase chemical output" strategy. While maintaining the annual crude oil processing capacity of 18 million tons unchanged, the project will drastically reduce refined oil output by 1.85 mt/a and increase ethylene feedstock production by 1.67 mt/a instead. Four key processing units will be newly built, including a 3 mt/a Deep Catalytic Cracking (DCC) unit. The annual ethylene production capacity will be expanded from the original 1 million tons to 1.64 million tons. For downstream industries, priority will be given to constructing new production facilities including a 300kt/a propylene oxide unit, a 240kt/a hydrogen peroxide unit, and a 100kt/a POE (polyolefin elastomer) unit, filling the domestic gap in high-end polyolefins. 2026 Progress:The project is in the critical stage of completion and commissioning. Full mechanical completion is expected by the end of 2026, with some units such as the propylene oxide plant having already taken the lead in trial operation.
