Core Viewpoint - The PVC-UH pipe industry in China is experiencing a decline in production, with an expected output of 1.683 million tons in 2024, representing a year-on-year decrease of 5.5%. This decline is primarily due to reduced market demand and a shift towards high-end products, prompting companies to focus on quality improvement and efficiency enhancement [1][8]. Industry Overview - PVC-UH pipes are a type of synthetic material made from polyvinyl chloride (PVC) resin, known for their high rigidity and ability to withstand internal pressure. They are widely used in urban water supply, drainage, agricultural irrigation, and aquaculture [3][4]. - The PVC-UH pipe industry is part of a larger PVC market, which has seen fluctuations in production from 2018 to 2024, with a notable increase in output expected in the coming years due to ongoing infrastructure investments [6][8]. Industry Chain - The PVC-UH pipe industry consists of an upstream segment that includes raw materials like PVC resin, stabilizers, and lubricants, a midstream segment focused on manufacturing, and a downstream segment that encompasses various application fields such as municipal engineering and agriculture [4][5]. Current Industry Status - The PVC-UH pipe industry is undergoing a transformation towards high-quality development, with production expected to decline from 1.66 million tons in 2021 to 1.53 million tons in 2024. This shift is influenced by external factors such as the pandemic and market conditions [7][8]. Competitive Landscape - The industry has established a competitive hierarchy, with leading companies like China Liansu and Gongyuan Co. occupying the top tier, holding nearly half of the market share. Other companies like Guditech and Weixing New Materials form the second tier, while numerous small and medium enterprises make up the third tier [9][10]. Development Trends 1. **Technological Innovation and New Material Research**: The industry is expected to advance towards smart technologies, focusing on modified techniques and composite materials to enhance performance [11]. 2. **Expansion of Application Fields and Market Demand**: The demand for PVC-UH pipes is anticipated to grow in new areas such as rural drinking water safety and geothermal systems, driven by urbanization [12]. 3. **Optimization of Industry Structure and Green Development**: The industry will likely see consolidation, with a push towards professionalization and sustainability, aligning with environmental goals [13]. 4. **International Competition and Cooperation Opportunities**: The Chinese PVC-UH pipe industry is becoming more competitive globally, necessitating technological collaboration and market expansion strategies [14].
