All pipes are identified by means of colour bands as follows:
Light pipe - Two Brown Bands.
Medium pipe - Two Blue Bands.
Heavy pipe - Two Red Bands (alternatively, the whole pipe may be painted red).
The colour bands are painted on one end of each length of pipe. All pipes are also hard marked with the ROBOR TUBE logo, the specification number (SABS 62) and a batch code at 1-metre intervals opposite the weld.
