According with the UNI5634/97 standard in civil and industrial installations, it is necessary that the color of the pipe identifies the fluid carried.

Tenaris has created Dalmine Thermo ®: steel pipe, coated with epoxy powder, which means no painting on site by the installer and even easier and safer identification of usage.

The coating is applied by fusing epoxy powder onto the surface of the grit-blasted pipe, preheated to about 200°C. The coating, with a minimum thickness of 50 microns, gives a working temperature of between -30 to +110°C, and has excellent adhesive properties and resistance to abrasion; allowing bending with a standard portable tool, with a mandrel having a minimum bending radius of 6 times the external diameter of the pipe.

Fretz-Moon pipe, ranging from Ø 1/2" to Ø 3", seamless pipe up to 10" and up to 4" for ERW pipes can be externally coated in epoxy resin; easy to work and weld, they can be installed without any preliminary surface treatment. Pipe coated in this manner is principally used in general civil and industrial installations, fireproof installations and natural gas distribution. It has excellent adhesive properties and allows bending with a standard portable tool, with a mandrel having a minimum bending radius of 6 times the external diameter of the pipe.
