ASTM A179 Seamless Boiler tubes
Features
- Seamless construction with no weld seam, so strength is uniform around the tube
- Cold drawn for tight tolerances on diameter and wall thickness
- Smooth inner surface that supports efficient heat transfer
- Low carbon chemistry that bends, flares, and flanges well during fabrication
- Every tube tested for pressure integrity before dispatch
- Available in custom lengths, end finishes, and surface treatments
