DIRECT ANSWERCorrosive-service selection needs actual composition, concentrations, water content, impurities, phases, temperature, pressure, velocity and upset/cleaning cases. The corrosion strategy may combine base material, allowance, lining, cladding and monitoring.
Corrosion design inputs
- Normal and upset chemical composition
- Water, contaminants and phase changes
- Temperature, velocity, erosion and crevices
- Design life, inspection and protection method
Relevant manufacturing capability
- Drawing, datasheet and equipment-list manufacturability review
- Self-manufactured and coordinated-supply scope identification
- Technical, quality, document and delivery clarification
Key notes
- A generic stainless grade or fixed corrosion allowance is not universally suitable.
