Safety first. Prevention first – let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment. **********************【Ten Years of Rapid Development in Chemical Engineering Equipment】Regular updates and summaries are available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Engineering Forum) *****************On November 12th, the straight-seam submerged arc welded pipes with a diameter of 610 millimeters and a wall thickness of 38 millimeters, developed by Bohai Equipment Company for the transport of supercritical carbon dioxide, passed the testing successfully. The geometric dimensions and mechanical properties of these products met all the technical standards required. This marks the successful trial production of straight-seam submerged arc welded pipes for supercritical carbon dioxide transport in China, with the largest diameter and thickest wall thickness. This product is primarily used for the sequestration of carbon dioxide and oil displacement to reduce carbon emissions; it can meet the demands for transporting tens of millions of tons of supercritical carbon dioxide. By filling the gap in products related to the \"dual carbon\" goals in China, it further enhances the competitiveness of this company’s transportation equipment in the clean energy sector
