Short answer
A steam hose replacement record should link the identity of the old assembly, the reason for replacement, the properties of the new assembly and the related documents. Writing only the replacement date is not sufficient for cause analysis. The new product and revision should be kept separate without deleting the old record.

Technical explanation
In hose maintenance, selection, inspection, use and replacement information complement one another. A replacement due to damage and a planned renewal should not be recorded with the same reason. The new product being the same nominal size does not mean it automatically inherits all service conditions of the old assembly. If the connection, length or route changed, these are also technical changes. The record becomes more meaningful when production and test documents are linked to a specific physical assembly.

How is it assessed in practice?
The recommended form includes the old serial number, new serial number, removal date, reason, observation photos and the accepted new revision. For example, if both the hose model and the outlet elbow were changed after a premature rupture, record both together. Add whether the old part was sent for examination and the result. A planned replacement interval should be documented as a site decision; a single life figure should not be produced for all steam hoses. Do not carry the old service history over to the new product without recording the reason for replacement and the identity of the new assembly.
Original editorial recommendation; not a clause of a standard.
Frequently asked questions
Can the old serial number be given to the new hose?
In the recommended traceability model, the new physical assembly is given a new identity. The old and new serial numbers are linked by a replacement relationship; the old event history is preserved.
