As an IS 1161:2014 Grade YST 310 certified product, Kamdhenu YST 310 25 NB MS CHS - (33.7 x 4 mm) - 6 mtr Length is a cold-formed CHS with 33.7 mm outer diameter, 4 mm wall, and 310 MPa minimum yield — engineered for high-load structural columns, heavy fluid transport, and demanding industrial applications. The 25 NB nominal bore pipe in 6 m standard lengths provides high yield strength delivering isotropic structural performance for heavy-duty service alongside clean circular surfaces for threading, welding, or galvanising.

• IS 1161:2014 YST 310 certified — 310 MPa yield for demanding industrial CHS applications
• Circular section provides maximum torsional stiffness per unit weight versus any open section
• Tight OD tolerance ensures repeatable fit-up at CHS-to-CHS and CHS-to-plate connections
• High strength enables longer unsupported lengths in column and strut design
• Surface suitable for shot blasting, priming, and full epoxy or PU protective coating systems

• High-pressure water transmission mains and bulk supply headers
• Industrial compressed air networks and high-pressure fluid distribution
• Structural columns, primary posts, and pipe piling in civil structures
• Space frame primary chord members and large-span roof node sections
• Oil and gas field surface flow lines and wellhead connection members
