An innovative pipeline protection solution designed to mitigate erosion caused by high-velocity or turbulent fluid flow.

Turbulent Flow Double Sleeve is a specialized erosion-resistant system utilizing a dual-layer design. The inner sleeve is precisely contoured or segmented to redirect or dissipate fluid momentum, reducing direct impact on vulnerable areas such as elbows, reducers, and flow entry zones.

The outer sleeve offers structural containment and pressure resistance, while the inner sleeve—crafted from ceramic composite, bimetallic steel, or alloy-lined steel—deflects laminar and turbulent erosive jets, disrupting harmful flow vectors before they damage the pipeline wall.

This technology is ideal for use in boiler tubes, ash transport lines, slurry pipelines, and desulfurization systems, where high-speed, particle-laden media typically accelerates wall thinning. Installing turbulent flow double sleeves significantly extends service life, minimizes unplanned shutdowns, and enhances system safety.

What is Turbulent Flow Double-walled Pipe

What is Turbulent Flow Double-walled Pipe?

Turbulent Flow Double-walled Pipe represents a revolutionary advancement in pneumatic conveying technology, specifically engineered to address the critical challenges of material blockage, wear resistance, and energy efficiency in industrial bulk material transportation systems.

Anti-blocking Technology

Intelligent air injection system automatically detects potential blockage conditions and responds with targeted air bursts to dislodge accumulated material.

Enhanced Heat Transfer

Turbulent flow creates chaotic fluid movement with rapid changes in velocity and direction, resulting in superior mixing and heat transfer performance.

Dual-tube Configuration

Inner auxiliary air pipe strategically positioned within the main conveying pipeline, equipped with precisely engineered nozzles and throttle orifices.

Key Benefits

Energy Efficiency

30–50% reduction in energy consumption compared to conventional systems due to lower conveying velocities and higher material loading ratios.

Reduced Maintenance

60–80% reduction in maintenance costs due to elimination of blockage-related downtime and reduced wear rates from low-velocity operation.

Extended Service Life

10–15 years service life expectation compared to 3–5 years for conventional systems, with pipe wear rates below 0.1mm/year.

Improved Reliability

98–99.5% system availability with blockage incidents less than 0.1% of operating time, enabling continuous production.

Cost Effectiveness

1–3 year payback period with 35–50% IRR, providing substantial long-term value through reduced operating costs.

Operational Flexibility

Start/stop capability without blockages, modular operation, and fully automated program control for enhanced operational flexibility.

Industrial Applications

Engineered for durability, our products support critical operations in energy, cement, chemical, and food sectors.

Power Generation

Coal handling, fly ash removal, limestone injection systems, and biomass fuel transport in power plants.

Cement Industry
