The Nezone YST 310 Medium Duty 40 NB MS Round Pipe - (3.2 x 47.9 mm) - 6 mtr Length is a structurally and hydraulically certified Medium Duty round pipe from Nezone in YST 310 mild steel, manufactured to IS 1239:2004 (Mild Steel Tubes, Tubulars, and Other Wrought Steel Fittings). This 47.9 mm OD × 3.2 mm wall section (40 NB) in 6 m standard lengths delivers consistent wall uniformity, a smooth internal bore for low-friction flow, and 310 MPa minimum yield — perfectly suited for heavy-duty structural, high-pressure, and long-span applications. The Medium Duty classification confirms it meets IS pressure and dimensional requirements for designed for medium-pressure fluid service and standard structural applications.
