A material upgrade should respond to the actual corrosion, erosion, temperature, solids, or contamination mechanism. Chemical name alone is not sufficient; concentration, temperature, velocity, aeration, and process variation can change suitability.
Engineering Inputs
Liquid composition and concentration
Normal and upset temperature
Solids, erosion, and velocity conditions
Existing material and observed failure mode
Required component and wetted area
Applicable material specifications and documentation
Prepare the RFQ
Send the service conditions, existing materials, failure observations, and required component scope for review.
