Expanded Polyurethane Thermal Coating Steel Pipe

Expanded Polyurethane Thermal coating steel pipe

Expanded Polyurethane Thermal coating steel pipe consists of a steel pipe inserted inside a jacket pipe normally made of polyethylene. Two chemical components, which upon contact form the polyurethane foam, are injected between the steel pipe and the jacket pipe, expanding to fill the annular space. Normally an anticorrosive system is applied to the steel pipe before the foam is injected in accordance with customer specifications.

The jacket-pipe, the density of the foam and the thermal insulation capacity of the coating system may be selected in accordance with project requirements.

The low thermal conductivity in conjunction with the physical properties of the polyurethane foam, enable the system to operate at temperatures ranging from -40º C to 120º C.

The external coating plant is equipped to coat pipes with a nominal diameter ranging from 4” to 26”, and lengths ranging from 8m to 13m.
