Flow control units chosen for Belgian project

An Arc Energy Resources product story

Arc Energy is fabricating the screens and Hydro-Brake flow control units for Storm King Overflow sizes ranging from 3 to 9m.

Arc Energy Resources has been awarded a contract to provide special screens and Hydro-Brake flow control units being installed as part of a combined sewer overflow project for the city of Namur in the Wallonia region of Belgium.

The screens and Hydro-Brake flow control units form an integral part of the Hydro Storm King overflow/swirl-cleanse systems to be installed at 35 sites in and around the city of Namur and along the river Meuse.

Senior Project Manager Martyn Rowland says Arc Energy is fabricating the screens and Hydro-Brake flow control units for Storm King Overflow sizes ranging from 3 to 9m, as part of Hydro's key component manufacturing programme for the contract.

The screen panels range from 600 to 2400mm in diameter and the perforated stainless steel material is butt welded to a 60 x 60mm stainless steel rolled angle.

Arc Energy Project Manager Martin Sandles says distortion is a real risk when welding components of this size and thickness, so the welding team in the company's dedicated stainless steel fabrication facility had to take special care to achieve the close tolerances required.

After welding, the finished screens were then coated.

The main fabrication of the Hydro Storm King Overflow / Swirl-Cleanse systems will be carried out under license by CFE EcoTech.
