假定波紋管的全部波紋都處于同一條件下，在計算時只研究波紋管波紋的單個半波。這樣，在研究中就不考慮端部波紋，雖然端部波紋的邊界條件與中間波紋有所不同。數(shù)值法是根據(jù)E.列斯涅爾對于變壁厚回轉(zhuǎn)薄殼產(chǎn)生軸向?qū)ΨQ變形時所列的非線性方程來解的。在推導(dǎo)E.列斯涅爾方程時，應(yīng)用了薄殼理論的一般假定，其中包括:與環(huán)殼曲率主半徑相比厚度很小的假定;材料的均一性和各向同性的假定。采用上述假定也會給計算帶來一定的誤差。因?yàn)樵谥圃觳y管時，管坯的軋制，拉深和隨后的波紋塑性成形會造成材料力學(xué)性能上的各向異性和不均勻性。 </p> <p> 2.美國EJMA 應(yīng)力計算方法 </p> <p> 波紋管的有效面積計算 </p> <p> 有效面積是波紋管的基本性能參數(shù)之一，它表征波紋管將壓力轉(zhuǎn)換為集中力的能力，在利用波紋管把壓力變成集中力輸出的場合，有效面積就是一個重要參數(shù)。 </p> <p> <br />

2、接頭用熱熔連接，成為一體，***無滲漏，其他材料用絲口連接，其防滲性較遜，也避免了膠水粘接的0性。 </p> <p> 3、耐高溫，耐壓性能好，輸送阻力小。PPR水管 </p> <p> 4、價格便宜適中。 </p> <p> 5、使用壽命長，按國家標(biāo)準(zhǔn)GB/T18742生產(chǎn)和使用時可以使用50年。 </p> <p> PPR是三丙聚乙烯的簡稱，采用熱溶接的方式，有**的焊接和切割工具，有較高的可靠性。價格也很經(jīng)濟(jì)。保溫性能也很好，管壁也很光滑!一般價格在每米4-8元(4分管)，。不包括內(nèi)外絲的接頭。 </p> <p> PPR管正式名為無規(guī)共聚聚丙烯管，是目前家裝工程中采用**多的一種供水管道。 </p><p> 性能指標(biāo)折疊剛度使金屬波紋管或其它彈性元件產(chǎn)生單位位移所需要的載荷值稱為元件的剛度，一般用"K"表示。如果元件的彈性特性是非線性的，則剛度不再是常數(shù)，而是隨著載荷的增大發(fā)生變化。一般工程用的波紋管類彈性元件，剛度允差可限定在+/-50%之內(nèi)。波紋管的剛度按照載荷及位移性質(zhì)不同，分為軸向剛度、彎曲剛度、扭轉(zhuǎn)剛度等。在波紋管的應(yīng)用中，絕大多數(shù)的受力情況是軸向載荷，位移方式為線位移。以下是幾種主要的波紋管軸向剛度設(shè)計計算方法: </p> <p> 1.能量法計算波紋管剛度 </p> <p> 2.經(jīng)驗(yàn)公式計算波紋管剛度 </p> <p> 3.數(shù)值法計算波紋管剛度 </p> <p> 4.EJMA 標(biāo)準(zhǔn)的剛度計算方法 </p> <p> 5.日本TOYO 計算剛度方法 </p> <p> 6.美國KELLOGG(新法)計算剛度方法 </p> <p> 除了上述六種剛度計算方法之外，國外還有許多種其它的計算剛度的方法，在此不再介紹。積極參與社會責(zé)任，先后向“5.12汶川大地震”、“4?20雅震”、“崇州老年協(xié)會”、“老年事業(yè)發(fā)展基金。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

廠家供應(yīng)的PPR顆粒有不同顏色，比如灰色等，但是多數(shù)公司都是購入透明原料，不同顏色是加入了不同顏色的色母料。 </p> <p> >PPR水管顏色和質(zhì)量有必然的聯(lián)系么? </p> <p> 沒有。但是白色PPR避光檢測不合格的情況要多些，而灰色、綠色則不存在這些問題。另外受生活習(xí)慣影響，北方多用白色PPR管材，而南方則灰色PPR管較多。 </p> <p> >PPR水管是分冷水管與熱水管如何區(qū)分? </p> <p> ·PPR管是分冷水管與熱水管的，其區(qū)別是冷水管上有藍(lán)色標(biāo)識線，熱水管是紅色線。 </p> <p> 另外，PPR管道上面有諸如 S5 S4 S3.2 S2.5等標(biāo)識，一般S5 S4為冷水管，壁厚較薄，S3.2 S2.5為熱水管，壁厚較厚。 </p> <p> <br />
