Hebei Cangzhou Lithium Wear-Resistant Pipeline Conveying Project

In the lithium processing industry, the conveying of abrasive materials such as lithium ore, concentrates, and tailings places extreme demands on pipeline systems. A recent project in Hebei Cangzhou addressed these challenges through a specialized wear-resistant pipeline conveying solution designed for long-term reliability and reduced operational costs.

Project Background

A lithium processing facility in Cangzhou, Hebei Province, operates a pipeline system that transports abrasive slurries and granular lithium materials over long distances. The original carbon steel pipelines suffered from rapid wear, leading to frequent replacements, unplanned downtime, and high maintenance expenses. The facility needed a solution that could withstand the abrasive nature of lithium materials while maintaining consistent flow and minimizing leakage risks.

Customer Challenges

The primary pain points for the customer included severe internal wear of standard pipelines, which caused wall thinning and eventual perforation within months of operation. This resulted in material leakage, environmental contamination, and safety hazards. Additionally, the frequent shutdowns for pipe replacement disrupted production schedules, reducing overall throughput. The high cost of replacing and disposing of worn pipes further strained the operational budget. The customer also faced difficulty in maintaining consistent conveying velocity due to uneven wear patterns, leading to blockages and reduced efficiency.

Solution Provided

headpowder engineered a customized wear-resistant pipeline conveying system using a multi-layer composite structure. The inner layer features a high-hardness ceramic or alloy lining that offers superior resistance to abrasive wear caused by lithium particles. The outer structural layer provides mechanical strength and pressure containment. This design was paired with optimized pipe geometry to reduce turbulence and minimize localized wear. The solution included advanced joint sealing technology to prevent leakage and easy-to-replace modular sections for quick maintenance. Installation was carried out with minimal modification to existing supports, reducing project downtime.

After implementation, the pipeline system demonstrated a service life more than three times that of conventional steel pipes under the same operating conditions. Unplanned maintenance events dropped significantly, and the consistent internal surface roughness ensured stable material flow. The customer reported a reduction in total cost of ownership, improved safety, and enhanced production reliability.
