Polyurethane insulation shell structure characteristics:

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

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

3) 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.

4) Strong temperature adaptability: the use of temperature range: greater than 70 degrees Celsius is less than 250 degrees Celsius, frozen media under the pipeline does not crack.

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 health.

7) Light and high strength: the relative density is between 1.5 and 2.0, only 1/4 to 1/5 of carbon steel, but the tensile strength is close to, or even more than carbon steel, and the specific strength can be compared with alloy steel.

8) Significant energy saving (good sealing performance, no leakage, better heat preservation effect).
