由于塑料波紋管的使用有一定的局限性，昆明給水雙壁波紋管廠家供應(yīng)，首先是受到充電和壓力的影響，其次，它會(huì)影響閥體內(nèi)閥門的流量。相反，金屬波紋管不同，它不受溫度和壓力的限制。材料選擇范圍廣，不受介質(zhì)限制，因此在惡劣條件下的波紋管大多是金屬波紋管。 </p> <p> 金屬波紋管并沒(méi)有具體的選型軟件，一般情況下，在對(duì)控制閥進(jìn)行選型時(shí)順便進(jìn)行波紋管的選擇，其材質(zhì)跟閥桿材質(zhì)相同（有時(shí)我們也認(rèn)為閥桿與波紋管的厚度不同，受腐蝕的情況也會(huì)不同，所以波紋管的材質(zhì)有時(shí)也會(huì)比閥桿的好），波紋管的伸縮量由控制閥的行程來(lái)決定，這些都是比較直觀的波紋管參數(shù)，至于其他的參數(shù)，例如體積變化率，軸向剛度，昆明給水雙壁波紋管廠家供應(yīng)，昆明給水雙壁波紋管廠家供應(yīng)、耐壓性等都是通過(guò)計(jì)算得出的，而這些參數(shù)的計(jì)算都是通過(guò)固定的公式（公式較多且繁瑣復(fù)雜，這里不一一列出），并沒(méi)有其獨(dú)特的方式。 </p> <p> 金屬波紋管可分為兩種類型：成型波紋管和焊接波紋管，根據(jù)不同的加工形式。成形波紋管，也稱為機(jī)械成形波紋管或一次性波紋管，是通過(guò)機(jī)械拉伸和壓縮制造的。焊接波紋管是將兩個(gè)波紋管的零件依次焊接而成。兩者的選擇方法相同。區(qū)別在于材料的選擇、準(zhǔn)確性。 </p><div style="width:100%;text-align:

HDPE雙壁波紋管是一種外壁是環(huán)狀結(jié)構(gòu)、內(nèi)壁潤(rùn)滑的管材，近幾年在小區(qū)、市政建設(shè)中得到了很多的運(yùn)用。由國(guó)外引進(jìn)到國(guó)內(nèi)，通過(guò)多年的開展，在產(chǎn)品類型、標(biāo)準(zhǔn)、用途上現(xiàn)已十分完善，是給排水用料中遍及的管材。剛?cè)峒鎮(zhèn)洌淳哂袧M意的力學(xué)功能和剛性的一起，兼?zhèn)鋬?yōu)良的柔韌性。雙壁波紋管可以滿意較大的剛度請(qǐng)求，一起還具有耐壓、耐沖擊的功能。如與陶瓷管、水泥管比較，不只質(zhì)量輕，還有很大的緊縮強(qiáng)度和杰出的耐沖擊功能。與實(shí)心壁管材比較，單位長(zhǎng)度的波紋管具有質(zhì)量輕、省資料、降能耗、價(jià)格便宜等特性。在平等負(fù)荷前提下，因?yàn)殡p壁波紋管的壁較薄，因而比同種質(zhì)料、平等標(biāo)準(zhǔn)的實(shí)心壁管材節(jié)省質(zhì)料30%一50%.內(nèi)壁潤(rùn)滑的雙壁波紋管可以削減液體在管內(nèi)流動(dòng)阻力，然后進(jìn)一步進(jìn)步運(yùn)送才能。 </p> <p> 耐化學(xué)腐蝕性強(qiáng)，可接受土壤中的酸堿的影響，可在特別場(chǎng)合下運(yùn)用。波紋形狀能加強(qiáng)管道對(duì)土壤中負(fù)荷抵抗力，又不添加它的曲撓性，以便連續(xù)敷設(shè)在高低不平的地上。接口銜接便利，密封性好，搬運(yùn)簡(jiǎn)單，現(xiàn)場(chǎng)施工極為便利。能減輕施工勞動(dòng)強(qiáng)度，加速施工進(jìn)度。在建筑施工中，如鋪設(shè)地下排水管道，選用波紋管比選用傳統(tǒng)剛性管可加速施工進(jìn)度5-10倍。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="昆明給水雙壁波紋管廠家供應(yīng)"

塑料埋地排水管屬于“柔性管”，即在破壞之前可以有較大的變形。而混凝土排水管屬于“剛性管”，即在破壞之前不可能有較大變形。當(dāng)埋在地下承受外壓負(fù)載時(shí)，“柔性管”和“剛性管”的機(jī)理是完全不同的。 </p> <p> 2、密封性和維修方面比較：在管道嚴(yán)密性方面，塑料管本身不會(huì)滲漏，而且管子的長(zhǎng)度長(zhǎng)、接頭少;另外橡膠圈承插連接，柔性接口，密封性好，抗不均勻沉降能力強(qiáng)，能適應(yīng)較大的角度變化，因此其滲漏量遠(yuǎn)低于混凝土管道，甚至可以做到零滲漏。而混凝土管道的滲漏在管道工程設(shè)計(jì)時(shí)，通常按照排水量的10%來(lái)考慮;如果地下水位低于管底時(shí)，會(huì)導(dǎo)致管內(nèi)水向外滲漏污染地下水，造成二次污染;如果地下水位高于管底時(shí)，會(huì)導(dǎo)致地下水向內(nèi)滲漏，加大管道的排水量，在污水管道接入污水處理廠時(shí)，將使污水處理廠的處理水量增加，加大了污水處理的費(fèi)用。此外，還有在流沙地區(qū)水泥管的沉管問(wèn)題，容易造成水土流失、管道下沉堵塞等非正常損傷事件，*在上海地區(qū)每年沉管修理費(fèi)就高達(dá)1000萬(wàn)元以上。
