Abstract
A fouling reducing device for the tubes of a tubular heat exchanger of the type that contains at least one turbulence-generating element lodged inside one of the tubes of the exchanger. The fouling reducing device is a turbulence-generating element made of a metallic alloy with a nickel content that is greater than 50% by weight, and further made of at least one metal chosen from among chrome and molybdenum. The turbulence-generating element has an improved resistance to corrosion when in contact with a hydrocarbon, such as crude oil.
Claims6
Fouling reducing device for use inside tubes of a tubular heat exchanger, comprising a turbulence-generating element,
- wherein said turbulence-generating element is brought, during its use, in contact with an environment that contains crude oil,
- said turbulence-generating element, comprises a metallic alloy whose nickel content is greater than 50% by weight and includes at least one metal selected from the group consisting of chrome and molybdenum to improve its resistance to corrosion, and
- said turbulence-generating element is in the form of a solenoid.
