耐壓力是波紋管性能的一個重要參數(shù)。波紋管在常溫時，波形上不發(fā)生塑性變形所能承受的比較大靜壓力，即為波紋管的比較大耐壓力在一般情況下，波紋管是在一定的壓力(內壓或外壓)下工作的，所以它在整個工作過程中必須承受這個壓力而不產(chǎn)生塑性變形。 </p> <p> 波紋管的耐壓力實際上屬于波紋管的強度范疇。計算的關鍵是應力分析，也就是分析波紋管管壁上的應力只要波紋管管壁上比較大應力點的應力不超過材料的屈服強度，波紋管所受的壓力就不會達到其耐壓力。 </p> <p> 同一波紋管在其它工作條件相同時，受外壓比受內壓時的穩(wěn)定性要好，所以，受外壓作用時的比較大耐壓力比受內壓時高。 </p> <p> 當波紋管兩端固定，如果在其內腔通入足夠大的壓力時，波紋管波峰處有可能爆破損壞。波紋管開始出現(xiàn)爆破時波紋管內部的壓力值稱為爆破壓力。爆破壓力是表征波紋管比較大耐壓強度的參數(shù)。波紋管在整個工作過程中，其工作壓力遠小于爆破壓力，否則波紋管將破裂損壞。 </p> <p> 當波紋長度小于或等于外徑時，其計算結果和實際爆破壓力很接近;對細長型波紋管其實際爆破壓力要低很多。爆破壓力大約為允許工作壓力的3~10倍。四川PPR康泰代理商社會責任責任擔當，綿薄之力。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

廠家供應的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)別是冷水管上有藍色標識線，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 /> </p><p> 波紋管用于力平衡式儀表時，其有效面積的穩(wěn)定性會直接影響著儀表的精度。所以在這種場合不但要求波紋管具有合理的有效面積，而且還要求有效面積在工作過程中不隨工作條件而變化。 </p> <p> <br /> </p> <p> 1.有效面積的概念和有效面積的變化 </p> <p> <br /> </p> <p> 有效面積是一個等效的面積，壓力作用在這個面積上將產(chǎn)生相等的軸向力。一般情況下，隨著內壓力的增**紋管有效面積變小，面隨外壓力的增加，有效面積變大。 </p> <p> <br /> </p> <p> 2.波紋管的體積有效面積 </p> <p> <br /> </p> <p> 波紋管在外力或壓差作用下，其體積變化量與相應的有效長度的變化量之比值稱為體積有效面積。 </p> <p> <br /> </p> <p> 3.波紋管有效面積的計算 </p> <p> <br /> </p> <p> 對波紋管有效面積提出的要求及其計算方法取決于波紋管的用途。如果波紋管用作彈性密封件或管路熱補償時，有效面積的意義*在于用來計算波紋管成形時的軸向力和使用系統(tǒng)中的推力。波紋管的有效面積計算值與實測值之間急有一些差別。一般情況下用**公式計算波紋管的有效面積，是可以滿足需要的。 </p> <p> <br /> </p> <p> 當波紋管用于力平衡儀表和需要將壓力轉換為力的場臺，應準確確定其有效面積，要求逐個進行測量。康泰始終以技術創(chuàng)新為發(fā)展基石。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

彈性特性金屬波紋管及其它彈性元件在某一指定煮上的位移與作用載荷之間的關系稱為彈性特性，而位移和載荷都應存元件材料的彈性范圍內波紋管類組件的彈性特性可以用函數(shù)方程、表格與曲線圖等形式表示。其彈性特性取決于各類彈性元件的結構及加載方式。元件的彈性特性可以是線性的或非線性的，非線性還可分為遞增特性和遞減特性兩種。 </p> <p> 彈性特性是波紋管及其它彈性元件的一個主要性能指標。儀器儀表和測量裝置中使用的彈性元件，在設計時一般總是力求使元件的輸出量與被測參數(shù)(載荷)之間呈線性關系。這樣可以采用較簡單的傳動放大機構實現(xiàn)儀表的等分刻度。康泰集團始終致力于“成為生態(tài)建材行業(yè)***企業(yè)，管通全球”的愿景。成都CPVC康泰總經(jīng)銷</p><p
