Cost Comparison Between GRE and PE Lined Steel Pipes

by | Sep 21, 2018 | Lining

SOX Scrubber installations and retrofits present some unique challenges for dealing with the acidic nature of the wash water lines. Polyethylene lined steel offers superior chemical resistance offering the longest lasting and cost effective solution.

When looking at retrofit costs, the total cost of an installed pipeline is what you are going to pay. Please take a look at an actual cost comparison of installed PE lined steel pipes to GRE pipes at a major Chinese dockyard.
