Boiler inspection

Annual technical testing and inspection of steam pot (boilers) and hot water boilers are as follows:

Checking control equipment and tools
thickness measurement of front, rear, body, rapper, furnace networks
hydrostatic testing process
Internal visual inspection of the water chamber
Internal visual inspection of the combustion chamber (furnace)
Checking the correct operation of control equipment such as control level, burner sensor, pressure switch, exhaust thermostat, etc.

Inspection reference standards:

standard BS2790: Steam and hot water boiler inspection
standard BS2790: Inspection standard for hot water boiler
BS2790-1992: International Standard British Standard Organization Code
Standard 13782: Technical specifications and test method for determining the energy consumption standard and instructions for energy labeling of boilers

Technical testing of steam boiler and hot water boiler is done in two stages:

Technical test in the construction stage of steam boiler and hot water boiler
Periodic technical test of steam boiler and hot water boiler

Note: The standard for making steam boilers is BS 2790 or ISIRI 4231 and the standard for making hot water boilers is BS 855 or ISIRI 7911.

Boiler inspection procedure and its classification:

Inspection during construction:

Manufacturer’s factory inspection
PIM session and ITP setting
Checking the submitted maps and confirm them
Checking welding instructions (WPS) and their approval (PQR)
Control of consumable materials (sheets, pipes and other materials used in the manufacturing process)
Supervision of assembly and dimensional control
non-destructive tests (VT, PT, MT, UT, RT) if needed
Hydrostatic test after confirmation of welding lines
Performance test after installation of boiler accessories
Issuance of inspection booklet during construction (including all available documents and inspection reports)
Issuance of certificates and inspection plates during construction according to the standard

Periodic inspection of steam and hot water boilers:

Examination of documents (inspections during construction)
External inspection of the boiler (including internal and external surfaces and checking the performance of the boiler accessories (if possible)
Thickness test
Hydrostatic test according to test pressure during construction
If there is no discrepancy, the periodic inspection certificate will be issued along with the inspection plate.
Due to the importance of how to build and inspect the boilers, the presence of inspection documents during construction, as well as certificates and inspection plates during construction is required for periodic inspections, and boilers that do not meet the above conditions are considered non-standard and any Inspection operations on them are not allowed.

Inspection during repairs:

Initial inspection of the boiler (troubleshooting and necessary inspections in accordance with the construction standard)
Issuance of repair agenda
Inspections during repairs
Checking repair documents
Non-destructive testing if required
Hydrostatic test
If there is no discrepancy, the repair confirmation certificate will be issued
