New Green Environmental Protection Spiral Steel Pipe

Insulation ssaw steel pipe has superior personality such as light weight, high strength, heat insulation, sound insulation, flame retardant, cold resistance, anti-corrosion, non-absorption, and turbulent construction. It has become a full-scale thermal insulation for construction, transportation, kerosene, chemical, electric power, refrigeration and other industries. Indispensable materials such as waterproof plugging and sealing. Insulated spiral steel pipe is used for anti-corrosion and cold preservation projects of various pipelines in the room surface, mixing heating pipes, local air-conditioning pipes, chemical industry, medicine and other industrial pipelines.

Overview 3PE foaming anticorrosive pipe has been developed as a superior thermal insulation and anticorrosion material since the birth of 3PE decomposition data in the 1930s. Its utilization range is becoming more and more common, and it is also because of its complicated construction, energy saving and antiseptic effect. It is used in a variety of pipelines such as heating, cooling, oil transportation, and steam transportation. It is used in a variety of pipelines such as heating, cooling, oil transportation, and steam transportation.

The insulated spiral steel pipe is thus highly woven from the polyether polyol composition and the multiple methyl polyphenyl polyisocyanate as chemical data. Pipeline anti-corrosion third layer: high-density polyethylene cherished layer is pre-made into a fixed-wall color (yellow) plastic pipe, its infection 1 is cherished 3PE anti-corrosion layer to avoid smashing hard material smash, 2 is anti-corrosion waterproof. The use of insulated spiral steel pipe. Cut and transport the various materials in the range of -50 ° C -150 ° C anti-corrosion and cold preservation project. It is widely used in the rural anti-corrosion and cold preservation projects of heating, warm rooms, cold storage, coal mines, kerosene ports, and chemical industries.

Pipeline anti-corrosion superiority 1 reduces the project cost. The full-scale measurement of the double-tube bundle heating pipeline can reduce the project cost by 25% (using FRP as a cherish layer) and 10% (using high-density polyethylene as a cherish layer). 2 hot flowers to eliminate low energy. Its thermal conductivity is:?=0.013—0.03kcal/m·h·oC, which is much lower than other commonly used anti-corrosion materials in the early years, and the anti-corrosion effect is improved by 4~9 times. Further, its water absorption rate is very low, about 0.2 kg/m2.

The reason for the low water absorption is because the closed cell ratio of the 3PE foam is as high as 92%. Low thermal conductivity and low water absorption, combined with high-density polyethylene or FRP cherished shell for anti-corrosion layer and surface waterproofing function, rotating the environment of laying the heating pipe "wearing wet cotton tampon" in the old-fashioned trench, greatly improving the overall heating pipeline Hot flower consumption, heat network heat loss is 2%, less than 10% of overseas specifications.

The reason why 3PE erw steel pipe has good anti-corrosion insulation function is long, because its rigid foam anti-corrosion layer is tightly bonded to the outer skin of steel pipe, which cut off the atmosphere and water soaking, which can be low.

Inferior antiseptic infection. At the same time, its foaming holes are closed and the water absorption is small. The high-density polyethylene casing and the FRP casing have inferior anti-corrosion, insulation and condensing functions. Therefore, the task steel pipe skin is well received by the outside atmosphere and water. As long as the internal water quality of the pipeline is well treated, the service life of the pipeline can be more than 50 years, which is 3 to 4 times higher than that of the old-fashioned trench installation and overhead laying.

Moreover, the pipeline is anti-corrosion, covers a small area, is fast in construction, and is unfavorable to the environment. Direct buried heat supply pipeline anti-corrosion does not require masonry to build a huge trench. As long as the anti-corrosion pipe is buried in the dark, the project land occupation is greatly enhanced, the earth excavation volume is increased by more than 50%, and the civil construction and concrete volume is increased by 90%. At the same time, anti-corrosion pipe processing and on-site trenching are easy to walk, as long as the site is explored, the contraction period can be about 50%.
