PPR任務(wù)管的功能特點(diǎn)：
Functional features of PPR task management:
1、耐腐蝕性好:除多數(shù)氧化劑外，可耐多種化學(xué)介質(zhì)的腐蝕，不會(huì)生銹，不會(huì)腐蝕，無電化學(xué)腐蝕。
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、耐熱功能好:當(dāng)任務(wù)水溫爲(wèi)70℃，可以臨時(shí)運(yùn)用，消費(fèi)直埋保溫管廠家，短期運(yùn)用水溫到達(dá)95℃，硬化溫度爲(wèi)140℃分量輕。密度爲(wèi)0.89-0.9g/cm3，直埋保溫管現(xiàn)場(chǎng)接頭保溫，僅爲(wèi)鋼管的九分之一，紫銅管的非常之一。由于分量輕，可大大降低運(yùn)輸費(fèi)用和裝置的施工強(qiáng)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、衛(wèi)生沒有毒: PP-R資料完全由碳、氫兩種元素組成，未添加任何有毒重金屬鹽波動(dòng)劑，資料的衛(wèi)生功能已經(jīng)過檢測(cè)。
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.
運(yùn)用壽命長(zhǎng)PPR管材在額外的運(yùn)用溫度和壓力下，運(yùn)用壽命長(zhǎng)達(dá)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:管材內(nèi)壁潤(rùn)滑，不會(huì)結(jié)垢，磨阻系數(shù)僅爲(wèi)0.007，遠(yuǎn)低于金屬管道，通水才能較同規(guī)格的金屬管道進(jìn)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、保溫功能好:由于PP-R資料導(dǎo)熱系數(shù)低，20℃時(shí)的導(dǎo)熱系數(shù)爲(wèi)0.21-0.24W/mk，比鋼管小得多，故PP-R管保溫性好。
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、收縮力小:由于PP-R資料彈性模量較小，因溫度變化發(fā)生的收縮力較小，合適采用嵌墻和地坪面層內(nèi)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、零碎銜接結(jié)實(shí):PP-R管道采用熱熔銜接方式停止銜接，將同種資料的管材和管件銜接成爲(wèi)一個(gè)全體，接口處的拉伸、彎曲和沖擊強(qiáng)度均高于管材本體強(qiáng)度，從而根絕了漏水的隱患。
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.
