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

We have the capability to produce and supply in the size range 180-406 mm though the common standardised sizes are only mentioned above.
| 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 mm width 5 mm height and 8 mm length. | |
| 4. | Internal soundness | The defects like cracks, pin holes, blow holes, flakes, pipes, axial porosity, sink marks, cold drops etc. will be within acceptable range. |
