The yellow jacket insulation steel pipe has obvious advantages:
1. Polyurethane hard foam has the function of being a versatile material, while also possessing many functions such as insulation, waterproofing, sound insulation, and vibration absorption.
2. Excellent insulation performance, it is currently the insulation material with low thermal conductivity (≤ 0.024) and high thermal resistance value among all building materials in China, and its thermal conductivity is only half of that of EPS foam polystyrene board.
3. The polyurethane rigid foam has a continuous and dense skin and nearly 100% high-strength interconnected wall closed pores, which have ideal impermeability. The spray coating method is used to achieve a continuous and seamless waterproof insulation layer, forming a seamless roof and an overall external wall insulation shell, with excellent waterproof and impermeable performance.
The yellow jacket insulated steel pipe does not require the construction of a large trench, only the insulated pipe needs to be buried underground, greatly reducing the land occupation of the project, reducing the amount of earthwork excavation by more than 50%, and reducing the amount of civil masonry and concrete by 90%. At the same time, the processing of insulation pipes and on-site trenching are carried out in parallel, with only on-site joints required, which can shorten the construction period by more than 50%.
The yellow jacket insulated steel pipe elbow is closely combined with the steel pipe conveying the medium, the polyurethane rigid foam insulation layer and the high-density polyhexene outer sleeve. This product is mainly used in urban central heating pipe network, oil transmission pipeline, water transmission pipeline in cold regions and industrial pipeline engineering in the production area. It has the advantages of efficient insulation, waterproof and anti-corrosion, simple construction, and is not afraid of plant root thorns. Trench laying is not required for construction, It can be directly buried in a frozen soil layer of 0.6-1.2 meters, with a 40% reduction in heat loss compared to traditional processes. Its service life is more than 3-5 times longer than other insulation and anti-corrosion materials, and its service life can reach 30-50 years.
