（3）管材環(huán)剛度的選擇是塑料管道設(shè)計的一項重要指標，因此應(yīng)從管道埋深、地面荷載、溝槽回填土的性質(zhì)和壓實系數(shù)以及施工荷載等綜合考慮確定。盲目采用高環(huán)剛度不經(jīng)濟。對車行道下埋深小于1.0m的管道，還應(yīng)考慮管道變形對路面的影響。 </p> <p> （4）外觀管材內(nèi)表面應(yīng)平整，外部波形應(yīng)規(guī)整；管材內(nèi)外壁應(yīng)無氣泡和可見雜質(zhì)，熔縫無脫開。管材在切割后的斷面應(yīng)修整，無毛刺。管材兩端鋼帶切口處應(yīng)在管材的同一縱向線。防腐層厚度粘接樹脂和外層聚乙烯為鋼帶的防腐層，應(yīng)符合CJ/T 225-2006標準中的有關(guān)規(guī)定。 </p>

波紋管主要包括金屬波紋管、波紋膨脹節(jié)、波紋換熱管、膜片膜盒和金屬軟管等。金屬波紋管主要應(yīng)用于補償管線熱變形、減震、吸收管線沉降變形等作用，***應(yīng)用于石化、儀表、航天、化工、電力、水泥、冶金等行業(yè)。塑料等其他材質(zhì)波紋管在介質(zhì)輸送、電力穿線、機床、家電等領(lǐng)域有著不可替代的作用。波紋管：壓力測量儀表中的一種測壓彈性元件。它是具有多個橫向波紋的圓柱形薄壁折皺的殼體，波紋管具有彈性，在壓力、軸向力、橫向力或彎矩作用下能產(chǎn)生位移。波紋管在儀器儀表中應(yīng)用***，主要用途是作為壓力測量儀表的測量元件，將壓力轉(zhuǎn)換成位移或力。波紋管管壁較薄，靈敏度較高，測量范圍為數(shù)十帕至數(shù)十兆帕。另外，波紋管也可以用作密封隔離元件，將兩種介質(zhì)分隔開來或防止有害流體進入設(shè)備的測量部分。它還可以用作補償元件，利用其體積的可變性補償儀器的溫度誤差。有時也用作為兩個零件的彈性聯(lián)接接頭等。波紋管按構(gòu)成材料可分為金屬波紋管、非金屬波紋管兩種；按結(jié)構(gòu)可分為單層和多層。單層波紋管應(yīng)用較多。
