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.
Other application:
In the oil and gas industry we inject chemicals in order.
To protect the infrastructure.
To optimize processes.
To assure flow.
And to improve productivity.
Inconel 625 is a material with excellent resistance to pitting, crevice and corrosion cracking. Highly resistant in a wide range of organic and mineral acids. Good high temperature strength.
Characteristics
Excellent mechanical properties at both extremely low and extremely high temperatures.
Outstanding resistance to pitting, crevice corrosion and intercrystalline corrosion.
Almost complete freedom from chloride induced stress corrosion cracking.
High resistance to oxidation at elevated temperatures up to 1050C.
Good resistance to acids, such as nitric, phosphoric, sulfuric and hydrochloric, as well as to alkalis makes possible the construction of thin structural parts of high heat transfer.
