Here we see two of our seasoned Miller fabricators putting some final touches on a surge tank made from carbon steel. This will to be shipped today to a southern pulp and paper customer for on-site installation.

 A surge tank is an attachment to a pressurized system designed to accommodate pressure changes. The purpose of a surge tank is to neutralize rises and falls in pressure to prevent system failures, blowouts, and other problems. The surge tank is normally attached at the highest point of the system. When the pressure rises, forcing fluids upward, they shift into the tank rather than blowing out the system.

 Recently a pulp and paper mill in British Columbia invested $1.2-million in a surge tank between the mechanical pulping line and the paper machines. This contributed to a record-setting month. Without the tank, the division was losing about 2 percent production or 800 tons, every month on average because it didn’t have the surge capacity.
