ROI Comparisons: Abrasive Slurry Pipelines

Pipelines with highly abrasive slurries require abrasion resistant polyurethane or rubber linings. The most common method of joining rubber and polyurethane lined pipe sections is bolted flanges. The following is a material cost comparison of high-pressure flanges and bolting vs. Joint Lock Ring™️ with welded joints.

Bare pipelines with welded joints are commonly used for long-distance high-pressure slurry pipelines. The wall thickness is increased to allow for erosion and corrosion. The major limitation of bare carbon steel pipelines are that they are not a bare pipeline transporting coarser particles (i.e. tailings) would need to be constructed twice or even three times over the period of time that one rubber or polyurethane lined pipeline would last.

The following are comparison charts of CapEx material costs over 25 years and construction considerations for bare vs. lined pipe.
