48、d bead removed internal weld bead not removed; Finish C: Internal and external weld bead rolled or removed. Finish A shall not be used for high frequency (HF) welded tube. The weld bead finish is at the discretion of the manufacturer unless Option 2 is specified. Option 2: The weld bead finish; A, B
49、 or C is specified by the purchaser. The finished tubes shall not include the welds used to join the lengths of strip prior to forming the tube.
