| Advantage Precision Tubes |
| Precision ERW tubes offer many advantages such as close tolerances on diameter & thicknesses, exceptional concentricity and a smooth finish, both inside & outside of the tubes.These features enable designers to obtain uniformity of flow under controlled temperature, pressure conditions, while fabricators can exercise greater control over close bending and tube alignment in butt welding. |
