45、Steelmaking process The steelmaking process is at the discretion of the manufacturer. 7.2 Tube manufacturing and delivery conditions 7.2.1 Tubes shall be produced from hot or cold rolled strip or plate/sheet, longitudinally welded across the abutting edges, by a continuous automatic process with or

46、without the addition of filler metal. The welding process is at the discretion of the manufacturer. Acceptable process routes and surface conditions are given in Table A.1. The choice of process route, base material, hot or cold rolled feedstock and the surface condition, is at the discretion of the

47、 manufacturer unless Option 1 is specified. Option 1: The process route and/or surface condition is specified by the purchaser from those in Table A.1.

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. However jointers are permitted when the purchaser specifies lengths in excess of the production maximum, if agreed at the time of enquiry and order. 7.2.2 Tubes produced in accordance with 7.2.1 shall be delivered in the following delivery conditions: - ferritic steels: as welded (+AR) or annealed (+A), at the discretion of the manufacturer;
