In all fields of the oil and gas industry, chemicals are injected into process lines and fluids. Take oilfield services, chemicals are used to film the side of the wellbore for improved stability. In pipelines they avoid build-up and keep the infrastructure healthy.
Characteristics
Excellent resistance to reducing and oxidizing acids.
Good resistance to stress-corrosion cracking.
Satisfactory resistance to localized attack like pitting and crevice corrosion.
Very resistant to sulfuric and phosphoric acids.
Good mechanical properties at both room and elevated temperatures up to approximately 1020° F.
Permission for pressure-vessel use at wall temperatures up to 800°F.
