- People measuring, selecting, or working with pipe
- Worth noticing
- It marks some values as awaiting a second source and cautions that derived bores from minimum-wall data are maximums.
Field notes
The reference separates standards that use different sizing conventions: steel schedules, PVC minimum walls, and PEX SDR. Its calculator is described as deriving the third value from any two of OD, ID, and wall thickness, with flow area, volume per metre, and linear weight also listed. The page notes that a bore derived from minimum-wall data is a maximum, not a guaranteed measured bore.
