聖蒂羅瀾地暖：PPR管材知識問答彙集

PPR管也是地暖管材中的一種，專門用來來接地暖安航時其他的管材。這種管材耐高溫、耐高壓，有很好的耐磨和耐腐蝕性，材料全部屬于環保無毒衛生的産品，符合國家要求的標准，因此一般使用在冷熱飲水管系統、建築供暖系統、運輸工具內部管道系統當中。今天，聖蒂羅瀾地暖小編通過以下7個來詳盡了解它。

1、PPR管規格是什麽？

單一的水管規格比較多，有4分管到10寸管等等。而PPR管材分爲冷水管、熱水管兩種，直接從外徑上來區別的話，家裝PPR管材的尺寸有20、25、32mm等規格的，另外爲了區分冷熱水管，還會把PPR熱水管用S2.5\S3.2來進行劃分，這兩種類型的水管是冷熱水管，其他尺寸的PPR管材則是單一的熱水管和冷水管。

2、PPR管常用顔色是什麽？

市面上銷售的PPR管主要有以下幾種顔色，白色、灰色、綠色和咖喱色，爲什麽會有這個區別，主要是添加PP-R管的色母料不同造成的。一般建議購買白色的PPR管，因爲極少數利欲熏心的廠家會使用回收料生産PPR管，通過添加色母料來掩蓋原料不純造成的瑕疵。

3、PPR管材的國家標准是什麽？

PPR管材的国家标准为GB/T 18742.2-2002。

4、管材的檢驗方式是什麽？

PPR管有三種檢驗方式，分別是靜液壓試驗（檢測管材的耐壓性能）、熱穩定試驗（檢測管材的耐高溫和高溫下的耐壓性能）、5000次冷熱水循環試驗（通過次檢測可以從理論上計算出管材使用年限爲50年）。

5、PPR管主要用途有哪些？

1）建築物的冷熱水系統，包括集中供熱系統；

2）建築物內的采暖系統、包括地板、壁板及輻射采暖系統；

3）可直接飲用的純淨水供水系統；

4）中央(集中)空調系統；

5）輸送或排放化學介質等工業用管道系統。

6、PPR管使用年限是多少？

一般來說，PPR管使用年限較長，如聖蒂羅瀾PPR管耐高溫，耐腐蝕，不結垢、不會滋生細菌，流體阻力小，在國家規定的使用條件下，可以長期在70攝氏度的溫度下工作，壽命可以達到50年以上，在等溫20攝氏度的環境下工作可以達到100年。

7、PPR管常見的連接管件有哪些？

三通：主要連接三個方向的水管。

束節：如果PPR管道不夠長，可以將其連接使用。

彎頭：分直角彎與45度彎頭，當PPR管需要拐角的時候使用。

繞曲管：兩根PPR在同一平面相交而不對接的時候使用。

堵頭：也叫悶頭，水管裝好後用來暫時封閉出水口，裝龍頭時取下。

內絲、外絲：連接龍頭、水表、其他類型水管用，家裝中大部分用到的是內絲件。

閥門：啓閉水流用

最後還要建議大家，一般在水電改造中，原有的水管都會更換，家裝公司和商家在建議裝修者安裝PPR管時全部選用熱水管，即使是流經冷水的地方也用熱水管。他們的說法是由于熱水管的各項技術參數要高于冷水管，且價格相差不大，所以水路改造都用熱水管。

Norah brought him over the typed letter. "We walked by the side of our teams or behind the wagons, we slept on the ground at night, we did our own cooking, we washed our knives by sticking them into the ground rapidly a few times, and we washed our plates with sand and wisps of grass. When we stopped, we arranged our wagons in a circle, and thus formed a 'corral,' or yard, where we drove our oxen to yoke them up. And the corral was often very useful as a fort, or camp, for defending ourselves against the Indians. Do you see that little hollow down there?" he asked, pointing to a depression in the ground a short distance to the right of the train. "Well, in that hollow our wagon-train was kept three days and nights by the Indians. Three days and nights they stayed around, and made several attacks. Two of our men were killed and three were wounded by their arrows, and others had narrow escapes. One arrow hit me on the throat, but I was saved by the knot of my neckerchief, and the point only tore the skin a little. Since that time I have always had a fondness for large neckties. I don't know how many of the Indians we killed, as they carried off their dead and wounded, to save them from being scalped. Next to getting the scalps of their enemies, the most important thing with the Indians is to save their own. We had several fights during our journey, but that one was the worst. Once a little party of us were surrounded in a small 'wallow,' and had a tough time to defend ourselves successfully. Luckily for us, the Indians had no fire-arms then, and their bows and arrows were no match for our rifles. Nowadays they are well armed, but there are[Pg 41] not so many of them, and they are not inclined to trouble the railway trains. They used to do a great deal of mischief in the old times, and many a poor fellow has been killed by them." To see the whole of Tokio is a matter of no small moment, as the area of the city is very great. There seems to have been no stint of ground when the place was laid out, and in riding through it you find whole fields and gardens so widely spread that you can readily imagine yourself to be in the rural districts, and are rather surprised when told that you are yet in the city limits. The city is divided into two unequal portions by the Sumida River, and over this river is the Nihon Bashi, or Nihon Bridge, which is often called the centre of Japan, for the reason that all the roads were formerly measured from it. It has the same relation to Japan as the famous "London Stone" has to England, or, rather, as the London Stone had a hundred years ago. "Yes--well--what of him?" As to the manner of cutting out or planing up the lumber for patterns, and the manner of framing them together, it is useless to devote space to the subject here; one hour's practical observation in a pattern-shop, and another hour spent in examining different kinds of patterns, is worth more to the apprentice than a whole volume written to explain how these last-named operations are performed. A pattern, unless finished with paint or opaque varnish, will show the manner in which the wood is disposed in framing the parts together. IV. Do you play golf or hunt or ride horseback or just sit in the sun “She did take the string, as the letter says,” Jeff nodded. “It was a secret—they didn’t broadcast it that the necklace was in the captain’s cabin, locked up in his safe. Nobody knew it, not even the lady’s personal maid, as far as anybody supposed.” He knew the answer to the puzzle of the missing emeralds! “Now we’ll shelve this mystery.” Mr. Everdail led the way to the tender which would transfer them to the yacht for the evening run around illuminated Manhattan. “Eat, and have a good time, Sky Patrol.” Forbes explained their early return, and spoke of the ranch. "It might be a garden, this territory, if[Pg 315] only it had water enough," he said; "it has a future, possibly, but its present is just a little dismal, I think. Are you greatly attached to the life here, Mrs. Cairness?" He was studying her, and she knew it, though his glance swept the outlook comprehensively, and she was watching the mail-carrier riding toward them along the road. It was the brother of the little girl who followed along behind them, and who ran off now to meet him, calling and waving her hand. "Oh, well, if you d?an't choose to tell me ... But I've eyes in my head." "We won't tell him that, though, Davy—we'll make out as it's pure patriotic feeling on our part." "Either you fetch him here or I send fur the police." Calverley made no reply; but, without looking either at Holgrave, or the man who had so fiercely and tauntingly addressed him, took the advantage offered—passed through the door of the foundry, and through the yielding ranks of sneerers and jibers outside; and mounting his horse, galloped rapidly away from the scene of his defeat, with the shout of a hue and cry following his track as far as the foresters considered their legitimate domain.
