Rurki powinny być dostarczane w następujących kształtach: okrągłe, kwadratowe, prostokątne i specjalne sekcje. Należy przeprowadzić analizę ciepła w celu ustalenia wartości procentowych określonych elementów. Jeśli zastosowane są wtórne procesy topnienia, analizę ciepła należy uzyskać z jednego wlewu oreknianego lub iloczyn jednego wlewu każdego pierwotnego stopu. Rurki powinny być pokryte warstwą oleju przed kształtowaniem do opóźnienia rdzy po określaniu
