CRUN(SZ:002272) Chan Ye Xin Xi Wang·2026-01-27 01:15Core Viewpoint - The domestic production level of spiral tube heat exchangers is gradually increasing, supported by national policies, and they are widely used in the petrochemical, coal chemical, and new energy sectors. The market for spiral tube heat exchangers is expected to grow significantly, with a projected compound annual growth rate of 21.9% from 2019 to 2025, reaching approximately 3.35 billion yuan by 2025 [1][7]. Industry Overview - Spiral tube heat exchangers are designed with a unique structure that allows for efficient heat transfer, making them superior to traditional shell-and-tube heat exchangers. They can accommodate various media and are suitable for high-temperature and high-pressure applications [3][4]. Industry Development Stages - The spiral tube heat exchanger industry has evolved through four main stages: technology introduction, domestic breakthroughs, large-scale application expansion, and intelligent green upgrades. The industry has transitioned from relying on imported technology to achieving significant domestic innovations [4][5]. Industry Chain - The industry chain consists of upstream raw materials (steel, rubber, graphite, plastics, coatings), midstream manufacturing of spiral tube heat exchangers, and downstream applications in sectors such as petrochemicals, coal chemicals, fine chemicals, new energy, and centralized heating [5][6]. Market Demand and Growth - The demand for spiral tube heat exchangers is increasing in the petrochemical sector due to the ongoing upgrades of refining projects driven by green and intelligent requirements. In the coal chemical sector, tightening energy-saving and emission reduction policies are creating opportunities for deeper applications of these heat exchangers [1][8]. Competitive Landscape - The market for spiral tube heat exchangers is relatively concentrated due to the high technical requirements for research, design, and manufacturing. Key players include Sichuan Chuanrun Co., Ltd., Zhenhai Petrochemical Construction Engineering Co., Ltd., and others [6][9]. Future Trends - The industry is expected to benefit from increased national policy support for high-end equipment manufacturing, accelerated technological advancements, and a shift towards high-pressure applications. The development of spiral tube heat exchangers is anticipated to continue expanding into new fields and applications [12][13][14].
