What do the analysis results mean?

Could an expert please explain what these analysis results mean?
This should be an elemental analysis similar to that of scale, carried out using X-ray diffraction or X-ray fluorescence analysis, with the results for various elements being presented in the form of oxides wherever possible. Based on the results, this sample consists mainly of calcium sulfate; it also contains a certain proportion of iron oxides (rust), which are products of corrosion in the process pipelines. Additionally, there is some sediment composed of silicon, aluminum, and titanium – with titanium possibly being part of the components of the process pipelines that corroded along with iron. There are also small amounts of chlorides, as well as salts or sediments formed from sodium and magnesium elements. Since the water content is not specified, calcium sulfate scale is likely to exist in the form of gypsum.
I have another question: I’m not quite sure what it means by ’the element is reported as an oxide’. Does that mean calcium makes up 45.656%, or is it calcium oxide that constitutes 45.656%? Thank you very much

It’s certainly calcium oxide; one molecule of calcium oxide and one molecule of sulfur trioxide (which is actually sulfate, as it results from the combination of sulfur and oxygen) combine to form calcium sulfate. The amount of calcium oxide plus sulfur trioxide already accounts for over 90%, and with rust and some silicate scales added, it’s basically 100%. It’s been almost a year now, and you’re back asking whether the pipe is blocked
It’s really congested often; I’ve changed it several times already
