PPR任务管的功能特点：
Functional features of PPR task management:
1、耐腐蚀性好:除多数氧化剂外，可耐多种化学介质的腐蚀，不会生锈，不会腐蚀，无电化学腐蚀。
1. Good corrosion resistance: In addition to most oxidants, it can resist the corrosion of various chemical media, no rust, no corrosion, no electrochemical corrosion.
2、耐热功能好:当任务水温爲70℃，可以临时运用，消费直埋保温管厂家，短期运用水温到达95℃，硬化温度爲140℃分量轻。密度爲0.89-0.9g/cm3，直埋保温管现场接头保温，仅爲钢管的九分之一，紫铜管的非常之一。由于分量轻，可大大降低运输费用和装置的施工强度。
2. Good heat-resistant function: when the task water temperature is 70 C, it can be used temporarily. Professional consumption of direct-buried insulation pipe manufacturers, short-term use of water temperature to 95 C, hardening temperature to 140 C light weight. The density is 0.89-0.9g/cm3. The joint insulation of the directly buried insulation pipe is only one ninth of that of the steel pipe and one tenth of that of the copper pipe. Because of its light weight, the transportation cost and the construction intensity of the equipment can be greatly reduced.
3、卫生没有毒: PP-R资料完全由碳、氢两种元素组成，未添加任何有毒重金属盐波动剂，资料的卫生功能已经过检测。
3. Health is not toxic: PP-R data are composed of carbon and hydrogen, and no toxic heavy metal salt fluctuating agent is added. The health function of PP-R data has been tested.
运用寿命长PPR管材在额外的运用温度和压力下，运用寿命长达50年以上。
The service life of PPR pipes with long service life is more than 50 years under additional operating temperature and pressure.
4、水流阻力小:管材内壁润滑，不会结垢，磨阻系数仅爲0.007，远低于金属管道，通水才能较同规格的金属管道进步30%以上。
4. Water flow resistance is small: the inner wall of the pipe is lubricated without scaling, and the coefficient of friction is only 0.007, which is much lower than that of the metal pipe, so that the water flow can be improved by more than 30% than that of the metal pipe of the same specification.
5、保温功能好:由于PP-R资料导热系数低，20℃时的导热系数爲0.21-0.24W/mk，比钢管小得多，故PP-R管保温性好。
5. Good heat preservation function: Because of the low thermal conductivity of PP-R data, the thermal conductivity of PP-R pipe is 0.21-0.24W/mk at 20 C, which is much smaller than that of steel pipe, so the heat preservation of PP-R pipe is good.
6、收缩力小:由于PP-R资料弹性模量较小，因温度变化发生的收缩力较小，合适采用嵌墙和地坪面层内的直埋暗敷方式。
6. Small shrinkage force: Because the elastic modulus of PP-R data is small and the shrinkage force caused by temperature change is small, it is appropriate to adopt the direct burying and concealed laying method in the embedded wall and the floor.
7、零碎衔接结实:PP-R管道采用热熔衔接方式停止衔接，将同种资料的管材和管件衔接成爲一个全体，接口处的拉伸、弯曲和冲击强度均高于管材本体强度，从而根绝了漏水的隐患。
7. Fragmentary bonding: PP-R pipeline stops bonding by hot-melt bonding, and connects the same material pipe and fittings into a whole. The tensile, bending and impact strength of the joint is higher than the strength of the pipe body, thus eliminating the hidden danger of water leakage.
