Let’s give a thumbs up and cheer for the achievements made by China’s chemical engineering technology and equipment industry. ********************** [Ten Years of Great Development in Chemical Engineering Equipment] This is a continuously updated summary thread; all are welcome to join the discussion. https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Engineering Forum) ***************** Gemmy Machinery: Domestically produced alternatives to ultra-long and ultra-heavy offshore steel wires have been developed; efforts are being made toward self-reliance and independence while targeting emerging markets. [May 7, 2024] According to China Petroleum Network (Special Correspondent Jiang Yan, Reporter Yang Rui), on May 5, an ultra-long and ultra-heavy galvanized compacted-strand steel wire designed and manufactured by Xianyang Gemmy Machinery for its client arrived at the user’s site and was successfully put into use. This marks the successful domestic substitution of such offshore engineering products.   The diameter of the galvanized, compacted strand steel wire rope used in this marine floating crane is 62 millimeters; its total length is 5730 meters. The weight of each individual strand exceeds 100 tons, and its tensile strength is over 1960 megapascals. It represents the heaviest galvanized, compacted strand product manufactured by Xianyang Gemstone Company. It is also one of the few marine steel wire ropes in China that meet the criteria of having a diameter of over 60 millimeters, a weight per strand of over 100 tons, and a tensile strength of over 1900 megapascals. Due to the complicated production process and intricate process control associated with ultra-long and ultra-heavy compressed wire ropes, Xianyang Bao Shi Company adheres to the principle of \"getting it right the first time\"; all departments work together to ensure that products are delivered on schedule. On the day of product acceptance, the customer stated that compared to purchasing foreign products, the purchase price was reduced by over 20%, and the delivery time was shortened by at least one-third.   In recent years, Xianyang Gemstone Company has consistently focused on emerging market sectors such as offshore engineering, formulating a series of plans for the development of domestically produced products. By accelerating the process of substitution with domestic alternatives, the company has achieved significant results. It has developed wire rope products in various diameters, including 60 millimeters, 76 millimeters, 95 millimeters, 120 millimeters, and 150 millimeters, thereby helping domestic marine equipment to achieve successful substitution with domestic products. These products have been widely recognized by customers, contributing to an increase in the reputation and market influence of the Gemstone brand.

On October 21, 2023, a galvanized single-strand steel wire rope with a diameter of 103 mm was successfully developed at Xianyang Gem Company. This achievement indicates that the company now possesses the capability to design and manufacture steel wire ropes with large diameters, filling a technical gap in this area for the group company and providing it with another valuable asset for competing in the market. Galvanized single-strand steel wire ropes are primarily used in applications such as the tension ropes of electric shovels in open-pit mines, marine permanent mooring cables, and the main suspension cables of long-span bridges. These applications require extremely high standards regarding product structure, manufacturing quality, and mechanical properties. Due to limitations in equipment capabilities and manufacturing techniques, China has long relied on imports for large-diameter galvanized single-strand steel wire ropes, which poses a serious constraint on the safety of energy projects related to deep-sea and offshore oil and gas exploration as well as mineral resource extraction. Xianyang Gemstone Company fully implements the important directives of the group company regarding the focused development of key core technologies. Aiming at the localization of permanent mooring cables for deep-sea oil and gas field construction, it coordinates the market demands for galvanized single-strand steel wire ropes used in bridge engineering, facility construction, and excavator slings, and invests in technological resources to intensify efforts in research and development.

December 26, 2019, 15:16 – According to reports from China Petroleum Network (special correspondent Jiang Yan, correspondent Zhang Zanbin), on December 24 it was learned that the first anchor cable in China with a diameter of 76 millimeters, produced by Xianyang Bao Shi Machinery Company, successfully passed expert evaluation and approval. This development lays the foundation for the domestic production of steel ropes and large-scale lifting equipment used in offshore operations. The 76-mm anchor cables produced by Xianyang Gemstone Company were previously monopolized by foreign brands; with domestic production now available, their price is only half that of a certain foreign brand, making them highly competitive in the market. The tensile strength of this anchor cable reaches 1960 MPa, exceeding that of other similar products available on the market. In addition, the surface of the anchor cable wire rope has been coated with a thick layer of zinc plating, providing strong corrosion resistance and making it more suitable for marine environments; moreover, biodegradable greases are used, meeting environmental protection requirements. Compared with ordinary anchor cable steel ropes of the same diameter, the successful production of this anchor cable will effectively promote research on the localization of mooring anchor cables for offshore oil lifting and pipeline laying ships, which is of great significance for further advancing oil exploration in China.
