Comprehensive Support to Ensure Successful Project Delivery

At Qingyuan Pipe, we supply high-performance mechanical spiral wound lining machines engineered for trenchless pipeline rehabilitation in municipal drainage, water supply, and wastewater systems. Our equipment is designed to handle large-diameter pipes (DN400–5000) with precision, efficiency, and compliance with global industry standards.

Key features of our equipment supply:

—Robust construction for heavy-duty field operations, ensuring long service life and minimal downtime.

—Modular design for easy transportation and setup, even in constrained urban or remote job sites.

—Full technical support including operator training, on-site commissioning, and spare parts availability worldwide.

—Proven performance in large-scale projects (e.g., Jiujiang Shilihe Interception Project, China) with diameters up to DN2200 and lengths exceeding 5 km.

Our spiral wound lining machines enable contractors to deliver cost-effective, environmentally friendly rehabilitation solutions, reducing excavation, traffic disruption, and project timelines.

At Qingyuan Pipe, we supply premium-grade spiral wound lining strips (also known as profile strips) designed for mechanical spiral winding rehabilitation of large-diameter pipes (DN400–5000). Our lining strips are manufactured from high-performance thermoplastics (e.g., HDPE, PVC-U) to meet global industry standards (ASTM, ISO, EN) and deliver long-term structural integrity for municipal drainage, water supply, and wastewater systems.

Key features of our lining strip supply:

—Material excellence: UV-stabilized, corrosion-resistant, and leak-proof thermoplastic strips, engineered to withstand harsh underground conditions and extend service life to 50+ years.

—Customized dimensions: Available in a wide range of widths, thicknesses, and profiles to match pipe diameter, rehabilitation requirements, and site-specific constraints.

—Full certification: All lining strips come with complete material certifications, performance test reports, and compliance documentation to meet municipal and regulatory requirements.

—Logistics support: Global supply chain capabilities, including bulk packaging, containerized shipping, and just-in-time delivery to minimize project delays.

—Quality assurance: Strict quality control at every production stage, from raw material sourcing to final inspection, ensuring consistent performance and project success.

Our spiral wound lining strips enable contractors to deliver seamless, cost-effective trenchless rehabilitation solutions, reducing excavation, traffic disruption, and long-term maintenance costs.
