Offshore essential valve material selection challenges
16 February 2021
Material corrosion is a significant risk and costly phenomenon in the offshore sector of the oil and gas industry. The offshore environment is a chloride containing marine atmosphere that can cause severe external corrosion of facilities. Moreover, oil and gas contain undesirable products such as carbon dioxide and hydrogen sulfide that corrode piping components internally.
In addition to corrosion risk, other parameters such as erosion, mechanical strength, availability of materials, and weight, affect the material selection for offshore facilities. ‘Facilities’ refers mainly to equipment, as well as piping components. The offshore sector of the oil and gas industry addresses the development of oil and gas fields ‘off the coast’ under the sea/ocean. Among the material selection challenges to be discussed, corrosion is the main concern.
