How should the all the water jetting equipment be marked?
All the components which need to be identified for service, maintenance or application should be permanently marked with enough information to identify the part, its use and performance and in a way which is easy to read.
Generally, the following components must be marked with:
- Pumps. They should be fitted with a permanently mounted name plate which provides the following information: manufacturer’s name or mark, model designation, serial number, year of manufacture, maximum volume and pressure performance, maximum input speed and maximum operating pressure.
- Hoses. They should be marked with the following information: manufacturers identification, date of manufacture, maximum temperature and maximum operating pressure.
- Adaptors and end fittings. They should be marked so the manufacturer’s identification and maximum operating pressure can be identified.
- Hose assemblies. They should be marked so that the appropriate certificate containing the following information can be clearly identified: the assembler, date of assembly, date of testing, maximum operating pressure.
- Re-ended and retested hoses. Hose assemblies which have been re-ended or retested should be marked so that the appropriate certificate containing the following information can be identified: the organisation performing the work, the organisation performing the retesting, date of testing, reference to the test reports.
