It is particularly suitable for the inspection of Gate, Globe, Ball and Checkvalves.Although the methodology in compiling this instruction is to systematically progress through theconstruction of a typical valve. Experienced, inspectors may interpret the intent of the instructionto accommodate local or novel practices or to utilise the instruction for a one-off, or alternativedesign of valve, the design having been approved by the client. Any such variations should benoted on the inspector's report.3.0PROCEDURE3.1GENERALThis instruction together with the associated check sheet may be used on any order or contract.It is intended to act as a guide to the inspector in the course of the inspection programme. Anypart of the document may be invoked and the sections to be used and the level of inspectionrequired will be specified on the check list.All tests and inspections will be carried out against the approved drawings, purchase orderspecifications, purchasers or company standards, and within the practices and rules of thecountry, state or province and any government decrees, laws, ordinance or regulation as mayapply.If any conflict or contradictions should be apparent in any of the above then the more onerousrequirement shall apply unless the purchaser or client directs otherwise in writing.The range of valve types, materials, sizes and pressure ratings included within standardmanufacturer's catalogues is large and infinitely varied and excludes the possibility of producingan overall instruction, which defines precisely to what extent inspection is required on anyspecific item or purchase order. The inspector will first establish whether the extent ofinspection is stipulated within the body of the Purchase Order documentation or Projectinstructions.3.2SPECIALISED VALVES FOR CRITICAL SERVICESWhen such stipulations are not provided, as a general guide, all valves over 8" NB will normallybe individually witnessed on test. With very large or special valves, such inspection may beextended to detailed component inspection of major components. Such detail inspection willalways apply to valves intended for high pressure steam, cryogenic, nuclear or other criticalservice, and in such instances, will extend to valves smaller than 8" NB.3.3GENERAL PURPOSE VALVESWith quantity orders for general purpose valves in the smaller sizes and pressure ratings in non-critical service, review of the supplier's material and test certification coupled with a monitoring ofvalve test and percentage strip and final inspection will normally suffice to establish whether theorder requirements are being satisfactorily met.Date:11/03/043.4REFERENCE DOCUMENTSApplicable codes and specifications.•Design code (to be stated on inspection report)•Purchase order specification•Purchaser's standards•Approved drawings•SGS company standardsApplicable codes and standards (sample only)•API 598 Valve Inspection and Test•API 6D.
