What are Metric Tube and Fittings?

This is a lightweight range of welded tube, fittings and flanges with thin walls.
An I/D based system.
This range IS NOT to be confused with the ISO range of tube sizes which are sometimes INCORRECTLY called ‘ISO Metric’ – The ISO sizes are a thin walled, lower cost alternative to ANSI Pipe and are not very popular in the CN.
Note that an ‘Isometric’ is a pipe-work plan used by engineers and defined as follows: Isometric is a mathematical method of constructing a 3 dimensional object without using perspective. Isometric was an attempt to make drawing 3-D images easy and more realistic. The mathematics involved mean that all lengths when drawn at 30 degrees can be drawn using their true length (in other words lines aren't shortened as with oblique drawings). An isometric drawing shows two sides of the object and the top or bottom of the object. All vertical lines are drawn vertically, but all horizontal lines are drawn at 30 degrees to the horizontal.
