41、Option 9 7 Manufacturing process 7.1 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 manufactured by a seamless process, and may be hot finished or cold finished. The terms “hot finished “ and “

42、 cold finished “ apply to the condition of the tube before it is heat treated in accordance with 7.2.2. Acceptable process routes and surface conditions are given in Table A.1. The choice of process route and surface condition is left to the discretion of the manufacturer, unless Option 1 is specifi

43、ed. Option 1: The process route and/or surface condition is specified by the purchaser from those in Table A.1. 7.2.2 Tubes shall be supplied in the delivery conditions given in Tables 6, 7, 8 or 9, as applicable. Possible delivery conditions are annealed (+A) for ferritic steels, quenched and tempe

44、red (+QT) for martensitic steels and EN 10297-2:2005 (E) 8 solution annealed (+AT) for austenitic and austenitic-ferritic steels. (See Annex B for guidance on heat treatment following fabrication and further processing.) For steel grade 1.4006, the purchaser shall specify the delivery condition, eit

45、her QT 550 or QT 650. The process route and surface condition for this grade shall be at the discretion of the manufacturer unless Option 1 (see 7.2.1) is specified. Solution heat treatment shall consist of heating the tubes uniformly to the appropriate required temperature and then cooling rapidly.

46、 The solution treatment may be omitted if the conditions during hot working and subsequent cooling are such that the mechanical properties of the product can be met and the requirements for resistance to intergranular corrosion as defined in EN ISO 3651-2 can be obtained. See Annex B for guidance on

47、 heat treatment during fabrication and hot working as part of further processing. 7.2.3 All NDT activities shall be carried out by qualified and competent level 1, 2 and/or 3 personnel authorised to operate by the employer. The qualification shall be in accordance with EN 10256 or, at least, an equi

The operating authorisation issued by the employer shall be in accordance with a written procedure. NDT operations shall be authorised by a level 3 NDT individual appr

49、oved by the employer. NOTE The definition of level 1,2 and 3 can be found in the appropriate standards, e.g. EN 473 and EN 10256. 8 Requirements 8.1 General Tubes, when supplied in a delivery condition in accordance with 7.2.2, using a process route and to a surface condition given in Table A.1 and inspected in accordance with Clause 9, shall comply with the requirements of this document.
