Crossover Main Replacement - Coke Oven Managers Association

Introduction
The first two options were not viable, firstly each of the
crossover mains had previously been “over-plated”, and this
would only prove to be a short-term repair.
Secondly even though it was possible to operate the plant on
a single Gas Collecting Main the operating tolerances were
too fine, due to the size of our oven design and size of out
Ascension pipes.
Stopping the coke making process to replace these crossover
mains was not an option, so plans were put together to
change all four mains on a “live gas” system.
This is believed to be a first for Tata Steel Europe if not
worldwide.
