聚氨酯保温钢管的特点
Characteristics of Polyurethane Thermal Insulation Pipe
聚氨酯发泡保温钢管的全称是高密度聚乙烯外护管聚氨酯泡沫塑料预制直埋保温管,由保送介质的,义务钢管、聚氨酯保温层、聚乙烯塑料外护管,经过设备依次向外结合而成。其结构爲:外维护层、保温层、防渗漏层三部分,外维护层材料爲聚乙烯夹克管或玻璃钢或其它材料。敷设方式有直埋、架空、地沟三种方式。
The full name of polyurethane foamed insulating pipe is polyurethane foam plastic prefabricated direct-buried insulating pipe with high density polyethylene outer protective pipe. It is composed of delivery medium, obligatory steel pipe, polyurethane insulating layer and polyethylene plastic outer protective pipe, which are combined outward in turn through equipment. The structure of the outer maintenance layer is composed of three parts: the outer maintenance layer, the thermal insulation layer and the anti-leakage layer. The outer maintenance layer is made of polyethylene jacket pipe or FRP or other materials. There are three laying methods: direct burial, overhead and trench.

聚氨酯保温钢管厂家
聚氨酯发泡保温钢管从里到外分三层结构:
Polyurethane foamed insulating steel pipe has three layers from inside to outside.
一层:义务钢管层:根据设计和客户的要求普通选用无缝钢管、螺旋钢管和直缝钢管。钢管表面经过先进的抛丸除锈工艺处置后。
First layer: Compulsory steel pipe layer: Seamless steel pipe, spiral steel pipe and straight seam steel pipe are generally selected according to design and customer requirements. The surface of steel pipe has been treated by advanced shot peening and rust removal technology.
第二层:聚氨酯保温层:用高压发泡机在钢管与外护层之间构成的空腔中一次性注入硬质聚氨酯泡沫塑料原液而成,即俗称的“管中管发泡”。
The second layer is polyurethane insulation layer, which is made by injecting rigid polyurethane foam plastics into the cavity formed between the steel pipe and the outer cover with a high-pressure foaming machine, commonly known as "tube-in-tube foaming".
第三层:高密度聚乙烯维护层:预制成一定壁厚的黑色或黄色聚乙烯塑料管材。聚乙烯无臭,无毒,手感似蜡,具有优良的耐低温功用,低运用温度可达-70~-100℃,化学动摇性好,能耐大多数酸碱的腐蚀(不耐具有氧化性质的酸),常温下不溶于普通溶剂,吸水性小,但由于其爲线性分子可缓慢溶于某些无机溶剂,且不发作溶胀,电绝缘功用优良,其作用一是维护聚氨酯保温层免遭机器硬物破坏,二是防腐、防水。
The third layer: high density polyethylene maintenance layer: Prefabricated a certain thickness of black or yellow polyethylene plastic pipe. Polyethylene is odorless, non-toxic, waxy-like and has excellent low-temperature resistance. The lowest operating temperature can reach - 70 ~100 C. It has good chemical shaking property and can resist corrosion of most acids and bases (not resistant to oxidizing acids). It is insoluble in ordinary solvents at room temperature and has little water absorption. However, because it is a linear molecule, it can slowly dissolve in some inorganic solvents, and does not swell, and has electrical insulation power. Excellent use, its role is to maintain polyurethane insulation layer from machine hardware damage, the second is anti-corrosion, waterproof.
