Precision pipes are used in all industrial applications (such as chemical, marine, gas, automobile, oil and so on) where requires high precision dimensions/ accuracy sizes, especially for machine, instruments production. In this case the ID tolerance could be H7, H8 or H9 depends on customers' request and the sizes. Stainless steel seamless tubes can also be machined by honing or SRB process to produce stainless steel honed tubes. Tolerances of stainless steel precision tube are usually according to customer's requirments, and mostly the precision tolerances are EN 10305-1, EN ISO 1127 D4/T4. Precision Small Diameter Stainless Steel Tube Typical Size Range: 0.25 25.00mm Wall Thickness: 0.05 1.0mm Typical Grades: 304, 304L, 316, 316L & 321. EN 10305-1, EN ISO 1127 D4/T4 2) Size range:Īccording to the thickness, precision tubes can be divided as thick wall precision tube and thin wall precision tube 3) Dimension tolerances: The production and inspection standards of precision pipes are the same with normal stainless steel seamless pipes, but with much more precision tolerance standards. Younglee manfactures and supplies precision tube in full range of stainless steel, and wide range of duplex / super duplex stainless steel grades. Precision pipe is charactrized by high precision dimension tolerances, and delivered in cold drawn or cold rolled, pickled, polished or bright annealed surface.
