The Industrial Plant Inspection article provides you with information about in-
service inspection of fix equipment in the industrial plants.
The content will introduce you the codes and standards and summaries of
important points for each equipment type.
The inspection department in the industrial plants generally takes care of the static
equipment; rotating, electrical and instrumental equipment are not in the scope of
the inspection department, and normally, maintenance department takes care of
those.
The following standards, codes and recommended practices are used for pressure
vessel inspection:
The last two items are specific codes for new construction; however, most of the
technical requirements for design, welding, NDE, and materials can be applied to
the inspection, rerating, repair, and alteration of in-service pressure vessels.
ASME PCC-2, NB-23 and API 510 can be used for pressure vessel repair.
The NB-23 code covers the rules and guidelines for in-service inspection, repair,
and alteration of pressure- retaining items.
The API 510 Training Course is 7.5 days video training program and available
online and is the Prep course for API 510 Pressure Vessel Inspector Exam.
Besides the student that successfully pass this training course exam, receive I4I
academy certificate with 60 hours training credit.
The following standards, codes and recommended practices are used for pressure
vessel inspection:
ASME PCC-2, NB-23 and API 570 can be used for piping repair.
The API 570 Training Course is 6 days video training program and available online
and is the Prep course for API 570 Piping inspector Exam. Besides the student
that successfully pass this training course exam, receive I4I academy certificate
with 48 hours training credit.
Following standards, codes and recommended practices are used for storage tank
inspection:
The last two items are specific codes for new construction; however, most of the
technical requirements for design, welding, NDE, and materials can be applied to
the inspection, rerating, repair, and alteration of in-service storage tanks.
The following standards, codes and recommended practices are used for steam
boiler inspection:
ASME Section VII Recommended Guideline for the Care of Power Boilers
API Recommended Practice 573; Inspection of Fired Boilers and Heaters
API Recommended Practice 577; Welding Inspection and Metallurgy
API Recommended Practice 571; Damage Mechanism Affecting Fixed
Equipment in the Refining Industry
ASME Section I; Rules for Constructing of Power Boiler
Section IX, Welding and Brazing Qualifications
The last two items are specific codes for new construction; however, most of the
technical requirements for design, welding, NDE, and materials can be applied to
the inspection, rerating, repair, and alteration of boilers.
The following standards, codes and recommended practices are used for process
heater inspection:
The last five items are specific codes for new construction; however, most of the
technical requirements for design, welding, NDE, and materials can be applied to
the inspection, rerating, repair, and alteration of in-service process heaters.
The API 510 determines the requirement for inspection interval and API RP 576
specifies the inspection practice.
For more information, please review the Pressure Safety Valve Inspection article.
This article covers shop inspection and in-service inspection. You may review only
the in-service inspection section.
The in-service code for other industrial valves such as Globe Valve, Gate Vale,
Check Valve and Plug Valve is addressed in the piping in-service inspection code
as stated in above. In other words, in API STD 570 and API RP 574.
If a major repair is carried out, then valve testing might be needed, which can be
done based on API Standard 598.
The technique is almost new and applied in processing plants and is used as a
supplementary recommended practice for inspection intervals, method of
inspections and scope of inspections.
For example, you may determine your pressure vessel internal inspection based
API 510 requirement or carry out the risk based inspection and determine the
interval, method of inspection and scope of inspection.
The API 510 allows you to choose this alternative method. API RP 580 is provides
the definition and general requirement for risk based inspection and API RP 581
introduces you to a specific quantitative methodology for risk based inspection
implementation in your plant.
The Plant inspection is very wide in scope, and a single article might not be enough
to cover all aspects of this.
