Problem: Our client's water valve on one of the power units had sprung a small leak that measured around 2 inches long. The unit was as old as the plant (40+ years) and once drained, we had discovered dry rot/wear where the leak had appeared from pressure. The leak needed to be fixed and we wanted to also address the remainder of the expansion joint to prevent future leaks.

Completion Photo 1: Access Into the Valve provided a chance to apply Belzona 2911, 2111 directly on the inside of where the leak had occurred. These products applied after preparing the steel+rubber.

Application Situation

The water valve was leaking causing a large amount of water to escape and Belzona offered a quick fix. The customer could bring the valve down and we repaired in half a day. They were able to go online the next morning.

Application Method

An MBX grinder and roughing brush were used to prepare the expansion joint and surrounding steel that needed to be addressed. Belzona 2911 conditioner and Belzona 2111 were mixed and applied with a brush and applicator.

Belzona Facts

Belzona offered a great solution that was relatively inexpensive. It offered an "in-satu" option that didn't require the removal of the valve.
