◆ 内层采用进口高级304不锈钢管材，能够确保其在运用过程中不生锈，不结垢，无污染。
Imported 304 stainless steel pipes are used in the inner layer to ensure that they are not rusted, scaled and polluted during operation.
◆ 中间高密度聚氨酯发泡保温层,采用进口优质硬质聚氨酯全自动高压设备发泡而成，该资料导热系数低，隔热性能好。南方冬天300米管网正常运转75℃热水时昼夜温差仅为1℃~~2℃左右。具有极为优良的隔热性。
_The middle high density polyurethane foaming insulation layer is made of imported high quality rigid polyurethane fully automatic high pressure equipment. The data has low thermal conductivity and good thermal insulation performance. In winter, the temperature difference between day and night is only about 1 ~2, when the 300-meter pipeline network operates normally at 75 C hot water. It has excellent thermal insulation.
◆ 外壳维护层采用高强度PVC/PE管。抗紫外线抗老化经久耐用,不受生物和化学腐蚀的影响，避免了外界水份、空气、细菌的侵入，大大防止了外来要素对保温管资料的毁坏。既保证了保温效果，又防止了保温资料定期维修的懊恼。可确保整体管材的运用寿命到达50年以上。
High strength PVC/PE pipe is used in the outer shell maintenance layer. Anti-ultraviolet, anti-aging and durable, not affected by biological and chemical corrosion, avoiding the invasion of external water, air and bacteria, greatly preventing the destruction of external elements on the insulation pipe data. It not only guarantees the thermal insulation effect, but also prevents the chagrin of periodic maintenance of thermal insulation data. It can ensure that the service life of the whole pipe reaches more than 50 years.
◆ 该产品集三种资料的优质性能于一体，一次性装置到位，敷设便当，缩短装置工期，从而节约运转费用和装置施工费用。
The product integrates three kinds of high-quality data into one. The disposable device is in place, the laying is convenient, and the construction period of the device is shortened, thus saving the operation cost and the construction cost of the device.
1、防水和防腐性能强，可直接埋入公开或水中，而传统的各类保温管都要附设管沟，这样工程烦琐，缩短时间，造价降低。
1. Waterproof and anticorrosion performance is strong, can be directly buried in open or water, and traditional types of insulation pipes should be attached with trenches, so that the project is cumbersome, shorten the time and reduce the cost.
2、运用寿命更长，经过测试，聚氨酯保温管寿命长达30-50年，大大降低了管网改换或者修理的费用。
2. The service life of polyurethane insulation pipe is longer. After testing, the service life of polyurethane insulation pipe is as long as 30-50 years, which greatly reduces the cost of pipeline network replacement or repair.
3、保温性能愈加突出，有数据证明，聚氨酯保温管热损失仅为于传统保温管材25%，可以节约大量能源的同时，又能明显减低本钱。
3. Thermal insulation performance is becoming more prominent. Data show that the thermal loss of polyurethane insulation pipe is only 25% of the traditional insulation pipe material, which can save a lot of energy, but also significantly reduce the cost.
4、良好的耐冲击性，可直接埋入公开冻土里。
4. Good impact resistance can be directly buried in open permafrost.
5、具有良好的机械能和绝热性能，通常状况下可耐温高达100℃。
5. It has good mechanical energy and adiabatic performance, and can withstand up to 100 C under normal conditions.
6、硬质聚氨酯泡沫，充沛填满钢管与套管之间的间隙，具有一定的粘接强度，使钢管、外套管机保管层三者之间构成一个结实的整体，不易别离。
6, rigid polyurethane foam, fully filled the gap between the steel pipe and the casing, has a certain bonding strength, making the steel pipe, the outer tube machine storage layer three constitute a solid whole, not easy to leave.
7、可设置报警系统，可以精确指示毛病的精确位置并自动报警，大大进步了维修的效率，保证管道平安运转。
7. An alarm system can be set up, which can accurately indicate the exact location of the fault and automatically alarm, greatly improving the efficiency of maintenance and ensuring the safe operation of the pipeline.
