Anti-erosion Dual-layer Pipeline Solution
The turbulent flow double sleeve minimizes erosion by altering high-velocity flow patterns with dual-layer sleeve construction, enhancing pipe durability in abrasive systems.
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.
Inner sleeve engineered to break or redirect erosive fluid flow, reducing direct impact and wall thinning.
Combines flow-interrupting inner layer with high-strength structural outer shell for comprehensive protection.
Inner lining made from ceramic, high-chrome, or alloy steels for superior abrasion and heat resistance.
Available in straight, elbow, Y-section, and transition designs to protect flow-sensitive regions.
Designed for slurry, ash, steam, or gas conveying at speeds up to 25 m/s or more.
Dramatically reduces maintenance frequency and enhances pipeline reliability in erosive applications.
Compared to conventional systems
Maximum transport range
Extended operational lifespan
Reliable operation uptime
