Analysis of the impact of environmental protection trends on the steel wire mesh composite pipe industry
2022-01-10
I. Policy and Regulation Drive Industrial Upgrading
- Green building materials certification accelerates
- Composite pipes are included in the recommended materials of the "Green Building Evaluation Standard", requiring a recycled plastic usage ratio ≥30%.
- National Standard GB/T 32439-2023 adds environmental protection indicators: the recycling rate of production waste needs to reach more than 95%.
- Pollution control policies force change
- EU REACH regulations restrict plastic pipe additives, promoting the complete replacement of lead-free stabilizers (cost increase 15%-30%).
- China's "ban on plastics" eliminates inferior PVC pipes, and the market share of composite pipes increases to 38.6% (2024 data).
II. Breakthroughs in Green Materials and Processes
| Innovation direction | Environmental value | Technical cases |
|---|---|---|
| Bio-based PE application | Sugarcane-derived products reduce carbon footprint by 52%, meeting carbon neutrality requirements | Lianchuang Group has developed bio-based composite pipes with a 40% renewable raw material rate |
| High-value utilization of recycled materials | The technology for crushing and re-forming waste pipes is mature, reducing reliance on virgin materials (cost reduction 12%) | Weixing New Materials achieves a 30% recycled material mixing ratio while meeting strength standards |
| Clean production technology | Electric melting process reduces energy consumption by 25% and VOCs emissions by 90% | Jiangsu Zhongtong Pipe Industry has built a photovoltaic power generation intelligent production line |
III. Structural Changes in Market Demand
- Explosive growth in incremental areas
- Sponge city ：Demand for permeable drainage systems surges, and the permeability of flexible composite pipes increases by 27%.
- Photovoltaic supporting ：Weather-resistant composite pipes are used in power plant circulating water systems, with a 35% increase in procurement in 2024.
- Traditional scene upgrades
- Municipal water supply pipe bidding clearly requires "no heavy metal leaching", and the share of composite pipes surpasses cast iron pipes.
- Agricultural irrigation uses thin-walled composite pipes (+25% flow rate), improving water-saving efficiency by 30%.
IV. Enterprise Transformation Challenges and Responses
| Challenges | Corporate countermeasures |
|---|---|
| Cost pressure | Large-scale application of recycled materials reduces costs, such as Lianhong Pipe Industry's construction of a 100,000-ton recycling and processing center |
| Technical barriers | Jointly develop nano-modified adhesives with universities (+20% interface strength), breaking through the performance bottleneck of recycled materials |
| Complex certification system | Establish a full life cycle carbon footprint tracking system to meet ESG disclosure requirements |
V. Future Directions of Environmental Protection
- Deepening the circular economy
- The goal is to achieve 100% closed-loop recycling of waste pipes by 2030, and the industrialization of chemical recycling technology is accelerating.
- Popularization of low-carbon materials
- Research and development of hydrogen-resistant composite pipes for hydrogen energy storage and transportation, with the proportion of bio-based PE increasing to 60%.
- Digital environmental protection supervision
- Mandatory access to blockchain traceability platforms, real-time monitoring of pipe material carbon emission data.
