Timely quotation for DN426 polyurethane anti-corrosion composite insulation pipe

Among all thermal insulation materials, polyurethane thermal insulation pipe has a relatively long service life. It contains some very * molecules, and has good stability and strong anti-aging property. When used under normal operation or pressure, it can guarantee its service life to reach 50 years.

The polyurethane insulation pipe contains high-strength polyethylene molecules inside, and its structure is relatively stable. It has high-strength resistance to natural gas corrosion, artificial gas corrosion, and liquefier corrosion. That is to say, there is no need for any other anti-corrosion equipment. Burying such pipelines in soil will not cause any corrosive effect from any chemical substances contained inside. Everyone can rest assured of this.

Polyurethane insulation pipes themselves have excellent seismic resistance, and their low-temperature brittleness temperature is relatively low. In addition, they can be safely used from minus 60 ° C to over 60 ° C, ensuring effective use within a safe range. Moreover, they have uneven settlement and relatively strong adaptability, especially during winter construction, where pipe leakage will not occur.

Polyurethane insulated steel pipes can maintain normal application in environments ranging from -50 to 180 degrees Celsius. They are a type of insulation pipeline material with strong mechanical properties, excellent insulation performance, and can be widely used and operated. Heating insulation steel pipes have good insulation performance, with heat loss only 25% of traditional pipes, and can save a lot of energy during operation, significantly reducing energy costs. The compressive strength of the insulation layer of the black jacket polyurethane insulation pipe, the radial compressive strength of the insulation layer foam or the compressive stress when the radial relative deformation is 10% shall not be less than 0.3MPa; When sampling the insulation layer of polyurethane insulation pipe to test the foam structure, foam density, pressure strength, water absorption and thermal conductivity, remove the foam leather that is close to the steel pipe and the external protection. The thickness of the removal layer should be 5mm and 3mm respectively. At least three samples are required for each test item. The samples should be evenly distributed on the same section of the annular insulation layer. The density of foam at any position of the insulation layer of black jacket polyurethane insulation pipe shall not be less than 60kg/m3, and the surface of foam shall be smooth and clean, without sticking or shrinking, uniform bubble holes, collapse or cracking. The black jacket polyurethane insulation pipe should be free of stains, shrinkage, delamination, and cracking. When testing as required, the total area of voids and bubbles on any insulation layer section should not exceed 5% of the total cross-sectional area, and the size of a single void in any direction should not exceed one-third of the thickness of the insulation layer at the same position
