Product Application Fields:
• As material for supercritical (ultra-supercritical) power station boiler economizers, superheaters, and reheater headers, the company has maintained its position as a strategic supplier of high-end materials for the three major domestic power groups—Harbin Electric Corporation, Dongfang Electric Corporation, and Shanghai Electric Group—since 2004.
• As material for the four major pipelines of supercritical (ultra-supercritical) power stations, including main steam pipelines, hot reheat steam pipelines, and feedwater pipelines, the products can replace imported ones and have been applied to the four major pipelines of power plants operated by major power groups such as China Huaneng, Datang International, China Huadian, China Guodian, and State Power Investment Corporation, as well as local power enterprises, and captive power plants in the electrolytic aluminum industry such as Shandong Weiqiao and Hangzhou Jinjiang.
• As material for main steam pipelines and steam headers in nuclear power conventional islands and nuclear islands, the company's products have been applied to nuclear power units of China Nuclear Power Engineering, China General Nuclear Power Engineering, and State Nuclear Power Engineering Company.
• As high-temperature pressure-resistant pipe material for power stations and auxiliary facilities in the coal chemical and petrochemical fields, it has been applied to large-scale coal chemical projects of Sinopec, PetroChina, Shenhua Group, and Yitai Group.
Product Performance Characteristics:
• During the extrusion process, the metal is in a triaxial compressive stress state, resulting in a dense internal structure and good comprehensive mechanical properties; due to the fast extrusion forming speed and small temperature drop, the billet temperature is uniform, and the deformation of each part of the steel pipe is uniform.
• Suitable for difficult-to-deform metal materials that are difficult or even impossible to process by rolling and forging methods, and can produce bimetallic materials and steel pipes with special-shaped cross-sections.
• High dimensional and shape precision of steel pipes, wide specification range, maximum outer diameter 1200 mm, maximum wall thickness 200 mm; short production process flow and high production efficiency.
