Graphskill SUMS – Standard Universal Measuring System
This method of identification was primarily devised to categorise pipe supports for ease of identification, storage, retrieval & computerised manufacture coding purposes.
It is principally a code made up of alpha numeric & punctuation which give the product it relates to a unique reference showing its category, its material & more importantly its dimensions.
It is being used to uniquely identify pipe support components but it can be readily adopted for most components in any industry.
