The spiral pipe is used as a conveying pipe to transport various fluids such as oil, gas, and water. It is like the blood vessels of our human body, which continuously transports and distributes the rational use of various energy sources for our motherland. It is precisely because of the high-quality and high-quality guarantee of the spiral tube that our industry can continue to develop with peace of mind, and our life can be carried out in an orderly manner.
Spiral pipes reduce project budgets. Under normal circumstances, the project budget can be reduced by 25% (using FRP anti-corrosion as the maintenance layer) and 10% (using high-pressure polyethylene as the maintenance layer) up and down. The heat loss is low and resources are saved. The heat transfer coefficient is: λ=0.013-0.03kcal/mhoC, which is much lower than other common spiral pipe thermal insulation materials in the past, and the actual effect of thermal insulation is increased by 4 to 9 times.
And its water absorption is very low, about 0.2kg/m2. The fundamental reason for the low water absorption is that the internal muscle rate of foamed polyurethane reaches up and down. Low heat transfer coefficient and low water absorption, coupled with high-pressure polyethylene or glass fiber reinforced plastic anti-corrosion maintenance shell with good roof insulation and external effect, has changed the situation of “wearing wet cotton clothes” in the traditional pipe trench laying heating pipe network, reducing the need for The overall heat loss of the heating pipe network, the heat loss of the heating pipe network is 2%, which is lower than the global standard of 10%.
The insulating layer has a good effect and has a long service life. Since the polyurethane material rigid foam plastic roof insulation is tightly bonded to the skin of the spiral tube, the entry of gas and water is blocked, and it can have excellent practical effects. At the same time, its polyurethane foam cells are all closed, and the water absorption capacity is not large. High-pressure polyethylene casing and glass fiber reinforced plastic casing have good insulation and mechanical equipment functions.
Therefore, the helical tube skin is hard to be corroded by external gas and water. As long as the water treatment of the internal structure of the pipeline is good, according to the detailed introduction of the raw materials, the application service life can reach more than 50 years, which is 3 to 4 times that of the traditional pipe trench laying and empty rack laying. Small footprint, fast construction, and beneficial natural environment maintenance.
