BS EN 16753:2016EN 16753:2016 (E) 5 Introduction A number of seamless steel pressure vessels designed and manufactured in a similar way as tubes, as referred to in ADR are used for applications other than the transport of gases, e.g. Ice Breaking

22、 Emergency Evacuation Vessels (IBEEV), Diving Support Vessels (DSV), power generation, hospitals, advanced research applications and marine installations such as heave compensation systems on semi-submersible drilling rigs, etc. This European Standard is applicable only to seamless steel pressure ve

23、ssels 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 operation of a plant or service. This European Standard provides information and procedures for t

24、he 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 of EN ISO 11120 and are designed to store compressed and liquefied gases. Other design standards a

25、re 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 19078. This standard is intended to be used under a variety of regulatory regimes. In case of conflict

26、, the applicable regulation takes precedence. BS EN 16753:2016EN 16753:2016 (E) 6 1 Scope This European Standard specifies requirements for using a combination of appropriate in situ (without dismantling), non-destructive examination (NDE) techniques, for example visual examination, acoustic emissio

27、n 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 liquefied gases for a further period of service. This European Standard is applicable only to pressure vess

28、els (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 operation of a plant or service. This European Standard does not apply to pressure receptacles used for the

29、 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 references The following documents, in whole or in part, are normatively referenced in this document an

33、oses of this document, the following terms and definitions apply. 3.1 acoustic emission (AE) activity number of bursts (or events if the appropriate conditions are fulfilled) detected during a test or part test 3.2 flow noise acoustic emission events caused by the action of pressurizing the vessel a

34、nd 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.

35、ing is performed 3.4 working pressure settled pressure of a compressed gas at a uniform reference temperature of 15 C in a full gas cylinder Note 1 to entry: See EN ISO 10286. 3.5 Kaiser effect absence of detectable acoustic emission until the previous maximum applied load level has been exceeded 4

36、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 inspection should be as stipulated in the national regulations for the gas concerned. In the absence of such re

37、gulations, 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 time interval shall be included in the written scheme of examination. At all times, the safety of all person

38、nel 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 1968); b) acoustic emission testing (see EN ISO 16148); c) internal and external visual examination (see

39、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) eddy current testing (see EN ISO 15548 (all parts); i) hardness testing (see EN ISO 9809-1). At the disc

40、retion 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 the time of the in situ inspection shall be evaluated using a different technique to be able to quantify (

41、location and frequency) and size any possible imperfection. BS EN 16753:2016EN 16753:2016 (E) 8 4.2 Pre-inspection site visit Prior to any tests taking place, a pre-inspection visit to the site of the tube installation shall be undertaken to gather all the necessary information to ensure that an app

42、ropriate 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 related to it are understood, the site owner/operator shall complete a questionnaire before the pre-inspection

43、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-shore, used in a diving application); b) the manufacturing standard/specification of the tube to be examined; c) d

44、etails 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 all water can be eliminated (see Annex D); 2) a listing of any applicable local regulations that apply to the in

45、 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 the tube (if relevant); 6) the type of any valve, pressure control device, ancillary item (e.g. pressure gauge)

46、 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 te

47、st pressure/hydraulic test pressure; 9) the environmental conditions at the test site (e.g. noise and vibration levels); and 10) a location-based risk analysis (see Annex D). If the collected information does not allow the use of this European Standard, such tube(s) shall not be tested and the owner

48、 informed accordingly. 4.3 On-site inspection 4.3.1 General Having gathered and analysed the data from the pre-inspection site visit (see 4.2), the most suitable test method(s) for the particular tube installation under consideration shall be selected. The selected methods shall form the basis of a

49、written scheme of examination for the installation being inspected. At all times the inspection work shall be carried out in accordance with the appropriate written procedures(s) for the test(s) to be performed. BS EN 16753:2016EN 16753:2016 (E) 9 Periodic inspection and testing shall comprise, as a minimum, of: a) a visual examination (see 4.3.2) of all accessible external surfaces, internal surfaces and an acoustic emission test (see 4.3.3) coupled with any other tests deemed necessary; or b) a visual examination (see 4.3.2) of all access
