DIN EN 16753:2016-09EN 16753:2016 (E) 5 Introduction A number of seamless steel pressure vessels designed and manufactured in a similar way as tubes, as
25、 referred to in ADR are used for applications other than the transport of gases, e.g. Ice Breaking Emergency Evacuation Vessels (IBEEV), Diving Support Vessels (DSV), power generation, hospitals, advanced research applications and marine installations such as heave compensation systems on semi-subme
26、rsible drilling rigs, etc. This European Standard is applicable only to seamless steel pressure vessels installed in locations where attempting any removal from their containing superstructure would be hazardous or difficult or where the downtime required to remove the tube would hinder a continuous
27、 operation of a plant or service. This European Standard provides information and procedures for the periodic inspection and testing of such refillable seamless steel vessels (tubes). Many of these vessels installed in various installations are certified by the manufacturer to meet the requirements
28、of EN ISO 11120 and are designed to store compressed and liquefied gases. Other design standards are also in use. An example of a similar approach to that adopted in this standard is that for compressed natural gas (CNG) cylinders installed on-board automobile vehicles which is described in ISO 1907
29、8. This standard is intended to be used under a variety of regulatory regimes. In case of conflict, the applicable regulation takes precedence. DIN EN 16753:2016-09EN 16753:2016 (E) 6 1 Scope This European Standard specifies requirements for using a combination of appropriate in situ (without disman
30、tling), non-destructive examination (NDE) techniques, for example visual examination, acoustic emission testing AT and ultrasonic testing UT when periodically inspecting and testing seamless steel pressure vessels (tubes) with a water capacity between 150 l and 3 000 l, used for compressed and lique
31、fied gases for a further period of service. This European Standard is applicable only to pressure vessels (tubes) installed in locations where attempting any removal from their containing superstructure would be hazardous, or where the downtime required to remove them would hinder a continuous opera
32、tion of a plant or service. This European Standard does not apply to pressure receptacles used for the transport of gases as described under the TPED. This European Standard only applies to pressure vessel (tube) assemblies where the designs permit all necessary inspections stipulated. 2 Normative r

37、or part test 3.2 flow noise acoustic emission events caused by the action of pressurizing the vessel and not by any structural flaws within it Note 1 to entry: This can be reduced by slowing the fill rate and/or filtering out such emissions electronically within the AE recording equipment.

39、absence of detectable acoustic emission until the previous maximum applied load level has been exceeded 4 Operational principles 4.1 General The periodic inspection and test shall comprise a pre-inspection site visit followed by an on-site inspection. The maximum time interval for the periodic inspe
40、ction should be as stipulated in the national regulations for the gas concerned. In the absence of such regulations, the time intervals for the gas concerned are given in Annex C. Where other organizations/institutions stipulate a shorter time interval, this shall be complied with. The applicable ti
41、me interval shall be included in the written scheme of examination. At all times, the safety of all personnel in the vicinity of the installation shall be taken into account. The techniques used to evaluate the tube condition within the installation may include: a) hydraulic pressure testing (see EN
42、 1968); b) acoustic emission testing (see EN ISO 16148); c) internal and external visual examination (see EN 1968); d) ultrasonic thickness survey (see EN 1968); e) ultrasonic flaw detection (see EN 1968); f) magnetic particle testing (see EN ISO 9934-1); g) radiographic testing (see EN ISO 5579); h
43、) eddy current testing (see EN ISO 15548 (all parts); i) hardness testing (see EN ISO 9809-1). At the discretion of the competent person employed for the task, other appropriate test techniques may be used, e.g. dye penetrant. Indication of any anomaly in the tube(s) under test that are revealed at
44、the time of the in situ inspection shall be evaluated using a different technique to be able to quantify (location and frequency) and size any possible imperfection. DIN EN 16753:2016-09EN 16753:2016 (E) 8 4.2 Pre-inspection site visit Prior to any tests taking place, a pre-inspection visit to the s
45、ite of the tube installation shall be undertaken to gather all the necessary information to ensure that an appropriate set of tests are performed for the installation and the suitability of the tube to be examined without dismantling. To ensure that the installation itself and any areas of concern r
46、elated to it are understood, the site owner/operator shall complete a questionnaire before the pre-inspection visit. The pre-inspection visit shall, as a minimum, identify and record: a) the application of the tube to be examined/tested (e.g. submersible, a static storage service offshore or on-shor
47、e, used in a diving application); b) the manufacturing standard/specification of the tube to be examined; c) details of the tube installation including at least: 1) the feasibility of conducting an in situ test at the desired location without dismantling e.g. post hydraulic testing to ensure that al
48、l water can be eliminated (see Annex D); 2) a listing of any applicable local regulations that apply to the in situ installation; 3) the nature of the gas contained; 4) the pressure rating(s) of the tube(s) to be examined; 5) the pipework configuration, and its pressure rating, leading to and from t
49、he tube (if relevant); 6) the type of any valve, pressure control device, ancillary item (e.g. pressure gauge) and their pressure ratings fitted to the tube or its pipework (if relevant); 7) the pressure rating and relief valve setting of the compressor (if relevant); 8) the design characteristics of the pressure vessel (tube) and associated installation to be inspected to withstand the acoustic emission test pressure/hydraulic test pressure; 9)
