Suggested Alloys for use

  1. Alloy C-276
  2. Alloy 625
  3. 316l austenitic stainless steel
  4. 2205 duplex stainless steels
  5. 90/10 Cupronickel
  6. Alloy 400
  7. Alloy 825
  8. Inconel 718

Types of corrosive factors occur at offshore platforms are:

  1. Temperature
  2. Chloride magnitude
  3. Partial pressure of carbon dioxide (CO2)
  4. Partial pressure of hydrogen sulfide gas (H2S)
  5. Atmosphere pH
  6. Availability of sulfur

Selection of applicable alloys

Inconel, Monel and Cupronickel alloys are widely used in the offshore platforms for their excellent corrosion resistant properties. Inconel 625 resists pitting corrosion and other types of attack in the severe conditions. High strength and resistance to hydrogen embrittlement and stress corrosion cracking. High corrosion fatigue strength and tensile strength. It is actually an outstanding choice for marine based applications. It is used in piping, flowlines, bellows, propulsion motors, blades and sheathing for undersea communication cables.

Alloy 400 is resistant to attack in the several corrosive agents such as high speed seawater. It offers excellent resistance to bio-fouling and microbial induced corrosion, it is an economical and durable choice for producing the bellows, platform risers, offshore rigs, pump columns and for splash zone sheathing.
