Let’s give praise and encouragement to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Engineering Equipment】Regular updates and summaries are available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On May 26th, reporters learned that the first domestically produced continuous tube of its kind, with the largest diameter and thickest wall thickness, was successfully manufactured by Gemstone Pipe Industry, filling a technical gap in the production of large-size continuous tubes in China. 　　Coiled tubing is regarded as the \"universal tool\" in oil and gas exploration and development, and it is indispensable in operations such as well workover, drilling, fracturing, and logging in oil and gas fields. Large-diameter coiled pipes are more widely used; they can be employed in the construction of transportation pipelines for oil and gas extraction on land, as well as in operations such as oil and gas transport and injection of water or gas at offshore oil and gas platforms. Their fatigue and corrosion resistance enable them to function effectively in complex marine environments. Previously, the manufacturing technology for large-diameter thick-walled continuous pipes with a diameter of 88.9 millimeters or more was monopolized by a few international giants. 　　In the face of technical restrictions, Gem Tube Industry established a specialized R&D team to overcome key technologies such as the forming, welding, and coiling of large-diameter thick-walled continuous tubes. This approach ensured precise seam dimensions and accurate parameter control for such tubes, thereby improving the quality of their welds and the stability of the welding process. 　　The coiled tubing launched this time set two records in China: the largest diameter and the thickest wall thickness among such products, breaking foreign monopolies. Its performance meets international advanced standards, marking a breakthrough in this field for China, from scratch.
