production process
The machine uses the advanced equipment and technology, online production pipeline and polyurethane foam pipe insulation pipe, to produce uniform foaming, inner wall and the outer wall distance accurately, without support. Good heat insulation effect, labor saving. High production efficiency.

advantages
The inner tube by using PPR, PERT or HDPE, instead of steel tube, long service life, no corrosion, no scale. Expansion coefficient is big, not easy to burst, convenient installation and use, poor thermal conductivity, thermal insulation. Fast, low cost.

applicable conditions
Thermal insulation pipe 1, project: the appearance of the HDPE spiral corrugated pipe, strong resistance to pressure, long service life, convenient transportation.
2, building (Civil) pipe, using PVC as raw material. Low cost, convenient transportation, anti-aging, outdoor installation appearance.

environmental requirements

Boreal applies, according to the different requirements of different thickness of insulation, foaming layer, to a better heat preservation effect.
