Selecting Correct Valves and Pumps Depend on Right Match of Alloy and Application (14051)
By A.H. Tuthill and A.P. Castillo, reprinted from Pulp and Paper, Volume 73, Number 2, February 1999. Pulp and paper mill engineers must be concerned with the corrosion resistance, abrasion resistance and quality of the cast stainless steels used for pumps and valves. These products obviously play a very important role in pulp and paper mills due to the tremendous amount of water, chemicals and other materials that a typical mill processes. However, much less information is published or readily available on the use of these cast alloys compared to the extensive literature on wrought alloys. This article provides guidelines for addressing these three cast stainless steel properties, and choosing the correct material for various mill applications.
