Hello @045web
Thanks for reaching out about your canonical URL. You mentioned that the canonical URL is not correct, but when I checked the page you shared, I don’t see anything wrong:
<link rel="canonical" href="https://www.tecnocurve.com/stainless-steel-tube-bending/" />
The Yoast SEO plugin uses self-referencing canonical URLs. This means that the canonical URL defaults to the URL of the page. But when you set something else as canonical, you are signalling that the page URL should be ignored, and the specified canonical URL should be included in the sitemap and consequently indexed by search engines.
