Alfiniti supplies extruded aluminum schedule pipe held to the standard tolerances published on this page: diameter, wall thickness, weight, length, and straightness.<\/p>\n\n\n\n

Diameter tolerance is controlled two different ways depending on wall. Schedule 5 and 10 pipe is held on mean diameter<\/strong>, the average of two diameters measured at right angles to each other at the same point. Schedule 20 and heavier is held on diameter at any point<\/strong>, and from NPS 2 up it is expressed as a percentage rather than a fixed decimal.<\/p>\n\n\n\n

Wall thickness carries a plus and minus band on Schedule 5 and 10, but on Schedule 20 and greater only the minus side is specified. The plus side is capped by the weight tolerance instead.<\/p>\n\n\n\n

If your part needs tighter OD control, a thinner wall, or better straightness than the standard extruded numbers below, cold drawing is the route. See Tube d'Aluminium \u00c9tir\u00e9 \u00e0 Froid<\/a>.<\/p>\n\n<\/div><\/div>\n\n
