Beiyu’s published tube envelope runs in 3 routes: capillary tube from 1 to 5 mm outside diameter with 0.1 to 2 mm walls, seamless tube from 5 to 325 mm outside diameter with 0.5 to 12 mm walls in lengths up to 12000 mm, and welded tube from 6.35 to 1219 mm outside diameter with 0.5 to 25.4 mm walls in lengths up to 22000 mm. Beiyu quotes tube in 10 grades from its factory sheet, Grades 1, 2, 5, 7, 9, 11, 12, 16, 17 and 23, so a duty that sits between Grade 2 and Grade 7 can also be priced against the lower-palladium Grade 16 and Grade 17.<\/p>\n
