Factors that influence corrosion performance of metal & alloy: Service Environment & Applications Material Condition & Fabrication
Levels of Corrosion Resistance
Chloride Stress Corrosion Cracking
Sulfuric Acid Oil Field Environments
Outstanding Nickel or Cobalt-Base Alloys – C-276
Nickel or Cobalt-Base Alloys – C-276
Nickel or Cobalt-Base Alloys – C-276
Excellent Duplex Stainless Steel – 2205 Metals and Alloys
Good Austenitic Stainless Steel - 316
Duplex & Austenitic Stainless Steel - 316
Duplex & Austenitic Stainless Steel - 316
Alloy Comparisons for selection in various environments
FRP Material Selection is as Important as Selecting Steel Type
Selecting the best suited materials for applications facing corrosive environments are key to long-term success
Glass Reinforcements Provides Strength and
Modulus
Orientation Maximizes Directional Properties
Glass Type Optimizes Corrosion Performance
Resin Locks fibers in place
Determines heat resistance, flame retardance
Certain types offer higher corrosion resistance
Factors that influence corrosion performance of FRP: Service Environment & Applications: Temperature, pH & concentration, velocity of corodent Material Condition & Fabrication: Fabrication process, design of the laminate
FRP Pipe System Length: 4,300 lineal feet of 12” & 16” diameter FRP pipe.
Weight Savings: 677,760 lbs. saved vs. 316 SS

Verify FRP Will Perform Better… …Than Traditional Materials
Corrosion Performance: FRP corrosion resistance in many cases surpasses stainless steel and
high nickel alloy
Corrosion Performance FRP 2205 SS C0276 Alloy
Hydrochloric Acid 900O C to 15% concentration
60O C to 1% concentration
80O C to 15% concentration
Add Chloride 100O C in all 65O C with 2,000PPM @ low
65O C with 50,000PPM @ low
Strength Properties: In the fiber direction, FRP is stronger than conventional steels and
C-276 Conventional steels and C-276 are both initially stiffer than FRP, but
yield and begin elongating early FRP is significantly lighter than other corrosion-resistant materials –
density is lower by a factor of four
FRP Company Specification Protocol
Every company using FRP should have an
internal FRP General Specification to ensure consistent quality material, design and fabrication methods are used.
This specification will include requirements for: Governing standards to follow Drawings and calculations Fabrication methods FRP Laminate properties FRP Laminate sequence
Goal: To Create Consistent Quality FRP Assets Across Your Enterprise
Inspection & Maintenance Protocol
Similar to metal you will want to conduct inspections of your FRP assets
Different Inspection protocols will be used depending on the severity of the chemical environment Visual Inspection Acoustic Emission Ultrasonic Destructive Testing Digital Radiography
