UltraPipe Pressure Ratings<br />
Available in sizes from 88.9mm O.D. to 457.Omm O.D., UltraPipe is created using continuous cast steel strip of low carbon equivalent, which is joined<br />
using the high‐frequency electric resistance welding (HFERW) process.<br />
This process produces a flawless, continuous longitudinal seam of unparalleled symmetry and strength.<br />
UltraPipe is a straighter, rounder pipe of more consistent wall thickness, and it has a tighter bevel tolerance than required by most standards.<br />
These features mean it can be used in a wide variety of applications, including:<br />
• Pressure piping for flammable, toxic, high pressure or lethal fluids and gases.<br />
• Pipelines for gas and liquid petroleum.<br />
• Structural and architectural uses in buildings and bridges.<br />
• Water bore casing. (Imported grade B and grade X42 line pipe does not comply with AS1396 due to the higher mechanical properties specified in<br />
this bore casing standard.)<br />
