Coke Oven Gas Main Restoration with Composite System

RAK repaired a severely deteriorated 42-inch Coke Oven Gas Main affected by ammonia-related corrosion and significant wall loss. Using a multi-layer composite system with a chemically resistant resin, the team restored the piping to its original design specifications, delivering a cost-effective solution while minimizing downtime and avoiding full replacement.

The Problem

A customer at a coke plant has a 42″ Coke Oven Gas Main that was experiencing <75% wall loss in the vapor space of the main due to high volume ammonia. There were significant leaks on the entire piping system.

The Solution

RAK utilized an engineered multi-layer composite system to bring this piping system back within its original design specifications. This was paired with a chemically resistant resin system designed to withstand constant exposure to high volume ammonia.
