BS EN 1591-4:2013EN 1591-4:2013 (E) 4 Introduction The competence of the bolting technicians is a key factor in the safe operation of a system containing pressurised bolted connections and in th
23、e achievement of the highest performance from a pressurised bolted connection. Design codes for pressurised bolted connections such as EN 1591-1 require controlled bolt tightening. Therefore, competent bolting technicians are needed so that the specified bolt load tolerances can be met and, where ap
24、propriate, the specified tightness requirement can be achieved. Training and competence, experience and knowledge are often confused with each other. Training is no guarantor of competence, nor is experience a guarantor of knowledge and understanding. Training, experience, and assessment of the abil
25、ity to apply knowledge are all required to achieve competence. The essential elements needed to achieve competency are: a) theoretical knowledge combined with practical experience gained on site or by simulated workshop activities; b) assessment by a competent assessor to verify that the required kn
26、owledge, skill and ability has been gained and can be applied in accordance with an operating procedure. These elements may be achieved through formal education and training, or experiential, work-based learning, or a combination of the two. Nevertheless, competency can only be demonstrated by the m
27、ethod indicated in this document. It sets out the training syllabi for not only the bolting technicians, who actually disassemble, assemble and tighten bolted joints that in service will be pressurised, but also the syllabi for the personnel who supervise those technicians, the responsible engineers
28、. Competency in the analysis of pressurised bolted connection failures is not required beyond use of knowledge gained during training. A correctly assembled and tightened pressurised bolted connection that fails in service requires specialist knowledge to understand why the failure occurred and is o
29、utside the scope of this European Standard. BS EN 1591-4:2013EN 1591-4:2013 (E) 5 1 Scope This European Standard is applicable to the bolting technicians, and their supervisors, the responsible engineers, who disassemble, assemble and tighten the bolted connections of whatever shape of critical serv
30、ice pressurised systems. A failure of a connection in such a system would endanger personnel, plant or the environment. A route for achieving competency in the skills required to safely and successfully disassemble, assemble and tighten pressurised bolted joints of any shape to a design bolt load us
31、ing documented work instructions is given in this document. The aim is the establishment of a joint capable of maintaining a leak-free status throughout its service life. This European Standard provides a modular training syllabus and an assessment process that can be used to determine the competenc
32、y of personnel who disassemble, assemble and tighten bolted connections, whatever their shape, fitted to pressurised equipment containing a medium at any combination of temperature and pressure. Bolting technicians have to assemble bolted connections of different levels of complexity. For this reaso
33、n, training matrices dealing with bolted connections of various levels of complexity and for different types of pressurised bolted connections are given in this document. The modular structure created allows a bolting technician, once competency in the foundation level has been achieved, to obtain c
34、ompetency in higher levels as required. Certification to this European Standard provides an attestation of general competency in accordance with the stated syllabi and assessments. Certification to this European Standard does not represent an authorisation to operate, since this remains the responsi
35、bility of the employer, and the certified person may require additional specialised knowledge of employer-specific procedures, processes and equipment. 2 Normative references Not applicable. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 man
