Note 1) Smallest unit for specifying diameter D values is 0.5 mm, and 0.5 mm for t values of 3 mm or less.<br />

Note 2) Products with t = 2 to 3 and D ≥ 221, or t = (3), 4, 5 and D ≥ 350 have welded seams.<br />

Products with t ≥ 3 have dual-sided welding. Figures in brackets indicate manufacturing range for nominal filtration accuracy 2 µm.<br />

Note 3) Products with outside diameter D ≥ 800 are finished by manual grinding.<br />

Welded sections are wire brushed to remove oxide scales. (Oxide bath cleaning is not performed.)<br />

∗ Minimum order quantity for products with diameter D < 100 is 10 pieces.<br />
