    Abstract: Fired heater tubes with improved resistance to corrosion and fouling suitable for use in thermal processing units of petroleum refineries and petrochemical plants are fabricated from a bulk alloy of an alumina-forming alloy which is capable of forming a stable oxide film on the surfaces of the tubes. The bulk alloy comprising about 3 wt. % to about 20 wt. % of Al, about 5 wt. % to about 30 wt. % Cr and at least one alloying component selected from Fe, Ni, Co, Si, Mn, B, C, N, P, Ga, Ge, As, In, Sn, Sb, Pb, Sc, La, Y, Ce, Ti, Zr, Hf, V, Nb, Ta, Mo, W, Re, Ru, Rh, Ir, Pd, Pt, Cu, Ag, Au and mixtures of these components.

    Abstract: The present invention describes the connecting of a corrodible material with a non-corrodible material by electron beam welding so that the corrodible material is not affected by non-corrodible material during the welding process. Employing an electron beam welding process not only minimizes unintended alloying of the corrodible element but also minimizes the width of the weld heat affected and fusion zones. This fabrication method is necessary to ensure that the corrodible element faithfully replicates the wastage of the subject metal.

    Abstract: The present invention is a mechanical oscillator for detection and measurement of corrosive foreign materials. The elements include a mechanical oscillator that is mechanically excited, wherein the mechanical oscillator has a resonant frequency, f, and a quality factor, Q. A fuse fixed to the oscillator to change oscillator amplitude to and from essentially zero to resonance amplitude. In a preferred embodiment, the mechanical oscillator has the shape of a tuning fork where one region is compatible with the service fluid and the other region is incompatible with the service fluid or other contaminant. The sensor alarms when a measured amount of the incompatible material has been removed or the physical strength of the material has been compromised.

The elements include a means for mechanical excitation, and a mechanical oscillator, wherein said mechanical oscillator has a resonant frequency, f, and a quality factor, Q. A fuse fixed to the oscillator to change oscillator amplitude to or from essentially zero to resonance amplitude. In a preferred embodiment, the tuning fork has one region compatible with the service fluid and the other region is incompatible with the service fluid or other contaminant.
