FRP energy saving insulation pipe

Performance index：

1. Working steel pipe: seamless steel pipe with outer diameter ≤ 219mm, steel grade 20; It is spiral seam double side submerged arc welded steel pipe with outer diameter ≥ 219mm.

2. polyurethane foam insulation: density 60kg/m ³， The temperature of conveying medium is - 50-140 ℃, which has been certified by CCOT and is resistant to 140 ℃.

3. Glass cloth: thickness: 0.13 ± 0.03mm； Mass per unit area: 130 ± 10g/㎡； Longitudinal tensile strength: ≥ 200N / 25mm; Latitudinal tensile strength: ≥ 150n / 25mm.

4. Unsaturated resin: Acid Value: ± 4.0； Viscosity: ± 25%； Gel time: ± 30%； Solid content: ± 3%。

Product advantages：

(1) Corrosion resistance: chemical inert material, excellent corrosion resistance, and according to the transmission medium to choose different corrosion resistance pipeline.

(2) High mechanical strength: good water pressure resistance, external pressure resistance and impact resistance, and can design and manufacture pipes and fittings according to the required pressure.

(3) Strong temperature adaptability: the service temperature range is greater than - 70 ℃ and less than 250 ℃, and the pipeline does not crack in frozen medium.

(4) Small fluid resistance: the inner wall of the pipe is smooth, and the roughness coefficient is 0.0084. Under the same flow rate, the pipe diameter can be reduced.

(5) Light weight, long life, light weight, convenient transportation, low construction cost, no maintenance, service life of more than 50 years.

(6) Maintain water quality: non toxic, transport drinking water, can maintain long-term water quality health.
