Combining structural strength with precise pipe geometry, the Nezone YST 310 Medium Duty 150 NB MS Round Pipe - (4.8 x 163.9 mm) - 6 mtr Length from Nezone is a Medium Duty ERW round pipe in YST 310 structural steel conforming to IS 1239:2004 (Mild Steel Tubes, Tubulars, and Other Wrought Steel Fittings). The 163.9 mm OD × 4.8 mm wall (150 NB) profile in 6 m lengths achieves an optimal balance of balanced wall thickness for reliable performance under moderate pressure and structural loads, smooth bore, and certified mechanical performance for high-pressure pipelines, heavy structural columns, and critical engineering applications. With minimum yield of 310 MPa and tensile of 450 MPa, this IS-marked pipe meets the demanding requirements of heavy-duty structural, high-pressure, and long-span applications with traceable, consistent quality.
