Pipe markers

A wrap or band identifying pipe contents and flow direction to the ASME colour scheme.

1 products · substrates: vinyl, polyester

What it is

A wrap or band identifying pipe contents and flow direction to a standard colour scheme, read by people following a line through a building rather than examining one point of it.

When to choose it

Choose a wrap over a flat label on anything round. A flat label on a small-diameter pipe tents at the edges, collects dirt underneath and peels - and on a pipe run, one missing marker in a sequence is the one somebody needed.

What decides the order

Pipe diameter drives the size, and the spacing drives the quantity. Markers are needed at every change of direction, either side of a wall or floor penetration, and at intervals along straight runs - which is almost always more units than a first count suggests.

Choosing between pipe markers

Pipe markers are specified by pipe diameter as much as by material, because letter height is tied to the size of the pipe and a marker sized for a small line is unreadable on a large one. The colour scheme follows the hazard characteristics of the contents and is deterministic once the contents are known, so the real decisions are size, legend, and attachment. Adhesive markers suit clean, dry, accessible pipe. Insulated, hot or dirty lines take strap-on carriers, because adhesive on lagging fails and adhesive on a hot line fails faster. Outdoor runs need UV stable stock, since the colour is carrying the message and a faded marker misinforms rather than merely fading.

What serialising pipe markers adds

The dangerous failure with pipe marking is not a missing marker but a stale one. An unmarked line prompts somebody to ask; a wrongly marked line suppresses the question entirely, which is worse. Nothing about a physical marker communicates when it was applied or whether the contents have changed since. A record of where markers went and when means a line that changes service produces a list of exactly which markers are now wrong, instead of a survey of every run in the building. For an artifact whose harm comes from confident misinformation, dating the assertion is the useful property.

The record mechanics are the same for every artifact and are set out on how inspection records work.

What happens after you order

Markers are proofed by legend and diameter so the set is confirmed before production, which matters because a marker of the wrong size for its pipe is unusable rather than merely imperfect. Production begins once the numbering is approved. Because markers are grouped by legend and diameter, a plant order is really a set of small orders sharing a delivery, and ordering the full set for a system at once is much cheaper than marking line by line. A partially marked run delivers very little of the benefit, since the value comes from identifying the line wherever you meet it.

The full sequence, including what the proof shows and how approval works, is on how ordering works.

Questions about ordering pipe markers

What size marker for my pipe?

Size follows pipe diameter, because letter height is tied to it. Give us the outside diameter of the pipe including any insulation and the legend you need, and the correct size follows from that. A marker sized for the wrong diameter is unreadable rather than slightly off.

Adhesive or strap-on?

Adhesive for clean, dry, accessible pipe. Strap-on carriers for insulated, hot or dirty lines, because adhesive on lagging fails and adhesive on a hot line fails faster. Getting this wrong produces markers that fall off within months and a run that reads as unmarked.

How many markers does a run need?

More than most people estimate. Markers go at intervals along the run and at every point where the pipe enters or leaves a space, at valves and at junctions. Estimate from run length and junction count rather than from the number of distinct lines.
