A through-flange for attaching a pipe to the curved sidewall of a vessel. A flange portion of the through-flange is contoured to match the curvature of the sidewall and thus can be glued directly to the sidewall. A retaining ring also being contoured to match the sidewall is inserted over a tubular portion of the through-flange.
