PressureCast Steel Pipe
PressureCast Steel Pipe is a patent-pending steel pipe manufactured
with a "twist". The "twist" is that once the steel cylinder is fabricated
with rubber gasket joints, a concrete lining is placed in the cylinder
and pressurized before the concrete is cured. The pressure pushes
the concrete against the cylinder, stretching the cylinder to a stress
below the steel's yield point. After the concrete is cured, the pressure
is released. The steel cylinder then compresses the concrete lining.
The exterior of the steel cylinder can be coated with mortar, tape,
or paint, as appropriate for the pipe service application. The steel
cylinder remains in tension even after all creep and shrinkage of the
concrete has occurred.
PressureCast Steel Pipe (PCSP) Case Histories
PressureCast Steel Pipe Projects
The first installation of Ameron's patent-pending PressureCast Steel Pipe was placed in an inverted siphon for the Gila River Indian Community. This 120" steel pipe, with a cylinder thickness on-fifth the thickness of a traditional steel pipe of the size and D/t > 1300, had sufficient stiffness and design to be delivered and installed without struts or end caps..
