ArcelorMittal Cleveland is one of the most productive steel
manufacturing facilities in the world. It is strategically located by
the Cuyahoga River in Cleveland, Ohio, and has stood on this site
since 1913. There are two blast furnaces - C5/C6 that feed two
steelmaking facilities capable of producing 3.8 million tons of
raw steel annually.
When ArcelorMittal noticed that a 60” diameter reinforced
concrete pipe (RCP) was separating at the joints at the PH3 river
water intake, they knew an emergency replacement or repair
would be necessary. In order not to disrupt the the high-volume
production demands placed on the manufacturing facilities,
they asked R.E. Warner & Associates to use a repair that would
not interrupt the continuous flow that ran through the structure.
The type of repair needed for this particular project posed some
challenges. The first was that the reline pipe would need to be
able to handle continuous pressure. The second was
that the opening would have to be maximized to maintain the
hydraulic requirements. The project contractor, G.C. Great Lakes
Construction Company, turned to Contech Engineered Solutions knowing that Contech had several reline
solutions available and would help to determine what might best suit their needs.
Contech suggested they use InnerFlow® Pipe Systems - a rehabilitation solution that utilizes a solid, smooth wall
high density polyethylene (HDPE) pipe. The pipe’s precise dimensioning creates a much tighter sealing joint than comparable reline products and would withstand the pressure requirements. Contech worked with
Indiana Reline to help assist with the installation process. Everything was delivered to the site and the 54”
diameter InnerFlow was slip lined directly into the existing, failing RCP using the dual push-face which allowed
more linear footage to be pushed into the existing pipe. The entire project took one week to complete.
