Sourced from AST PIPES's certified ERW pipe manufacturing facility, the AST YST 210 Heavy Duty 65 NB MS Round Pipe - (4.5 x 76.3 mm) - 6 mtr Length is a Heavy Duty round pipe in YST 210 steel built to IS 1239:2004 (Mild Steel Tubes, Tubulars, and Other Wrought Steel Fittings). The 76.3 mm outside diameter × 4.5 mm wall (65 NB) in 6 m cut lengths provides engineered for high-pressure fluid service and heavy structural loading conditions with a guaranteed tensile of 330 MPa and thicker wall construction delivering maximum pressure rating and superior mechanical strength throughout. Consistent roundness, flush weld seam, and tight dimensional tolerances ensure seamless integration with IS-standard fittings, flanges, end caps, and threaded couplings across all installation types.

• IS 1239:2004 Heavy Duty pipe in YST 210 — IS-marked for certified structural and hydraulic assurance
• Section: 76.3 mm OD × 4.5 mm wall | 65 NB — thicker wall construction delivering maximum pressure rating and superior mechanical strength
