Round Billets

Continuously Cast Round Billets are used to produce seamless pipes used for industrial applications that require transportation of steam, water, gas, pol and air under high pressure in sectors like energy, petrochemical, automotive industries, steel, cement et. or in machinery manufacturing. Round Billets can be supplied meeting specific requirements of customer or as per any internatioaln standard like API, EN, ASTM etc.

*We have the capability to pruduce and supply in the size range 200-406 mm though the common standardised sizes are only mentioned above

Physical Parameters:

1. Ovality ≤ 2%
2. Straightness Maximum 80 mm over entire length (12 meter) of single billet
3. End of Bars Bars will be delivered having the ends gas cut. The deviation from the perpendicular will not exceed 5 mm, measured from a normal plan to the external surface. Burrs on the edge after gas cut shall not exceed 25 mrn width 5 mm height and 8mm length.
4. Internal soundness The defects like cracks, pin hales, blow holes, flakes, pipes, axial porosity, sink marks, cold drops etc. will be within acceptable range.
