Radiant follows a 4 Part Joint Integrity Tags which are multi coloured.

How it works

Each tag has a unique number which should be recorded against the isometric line drawing, P&ID or database indicating the details of the flange joint and building up a history of the work conducted on the joint.

Whilst work is carried out on the joint, the related stage tag is marked by the fitter and then parted from the others and returned to the central person(s) responsible for the overall integrity of the works being conducted.

The person can collate all of the tags and quickly ascertain which joints still need to have work on them before the plant can be returned to service. The tag information is recorded and builds a maintenance record for that joint and the pipe run.
