of boiler shell-to-endplate and furnace-to-endplate welded joints (SBG 1) Oxygen impurities in the boiler water/steam and inadequate pH (water chemistry) control, among other contributing factors, cause a hostile environment within the boiler confines. The prime purpose of the ultrasonic examinations was to detect cracking from the toe of

The pH factor is the most important factor influencing scale formation and the corrosive tendencies of boiler water. The pH should be maintained between a minimum of 10.5 and a maximum of 11.0 to prevent acidic corrosion of boiler tubes and plates, and to provide for the precipitation of scale forming salts before scale is deposited.

24/06/2014 · It comes into play with steam boilers because a pH between 7 and 9 (slightly alkaline) is just right. If the pH is lower than that, the water will start eating the pipes. If its higher than that, the water wont corrode metal, but it may begin to foam, and thats not good. Hold that thought for a moment.

Causes: Most commonly associated with excessive deposition on ID tube surfaces, coupled with a boiler water low pH excursion. Water chemistry upset, such as what can occur from condenser leaks, particularly with salt water cooling medium. Leads to acidic (low pH) contaminants that can be concentrated in the deposit.
