聚乙烯雙壁波紋管具有怎樣的性能特點

抗外壓(ya)能(neng)力(li)強(qiang)： 　　外壁(bi)(bi)(bi)呈環形(xing)波(bo)(bo)紋(wen)(wen)(wen)狀結構，大(da)(da)大(da)(da)增(zeng)強(qiang)了(le)管(guan)(guan)(guan)(guan)材(cai)的(de)(de)(de)(de)(de)環剛度(du)(du)，從而增(zeng)強(qiang)了(le)管(guan)(guan)(guan)(guan)道對土壤負荷(he)(he)的(de)(de)(de)(de)(de)抵抗力(li)，在這個(ge)性(xing)能(neng)方面，聚(ju)(ju)(ju)(ju)乙(yi)烯(xi)雙(shuang)(shuang)(shuang)(shuang)(shuang)(shuang)壁(bi)(bi)(bi)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)與其(qi)他管(guan)(guan)(guan)(guan)材(cai)相(xiang)比(bi)較具有明顯的(de)(de)(de)(de)(de)優勢。 　　工(gong)(gong)(gong)(gong)程造價低： 　　在等負荷(he)(he)的(de)(de)(de)(de)(de)條(tiao)件下(xia)，聚(ju)(ju)(ju)(ju)乙(yi)烯(xi)雙(shuang)(shuang)(shuang)(shuang)(shuang)(shuang)壁(bi)(bi)(bi)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)只(zhi)需要較薄的(de)(de)(de)(de)(de)管(guan)(guan)(guan)(guan)壁(bi)(bi)(bi)就可以滿足要求(qiu)。因此，與同材(cai)質規格(ge)的(de)(de)(de)(de)(de)實(shi)壁(bi)(bi)(bi)相(xiang)管(guan)(guan)(guan)(guan)比(bi)，能(neng)節約一(yi)半左右的(de)(de)(de)(de)(de)原(yuan)材(cai)料，所以聚(ju)(ju)(ju)(ju)乙(yi)烯(xi)雙(shuang)(shuang)(shuang)(shuang)(shuang)(shuang)壁(bi)(bi)(bi)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)造價也(ye)較低。這是(shi)該管(guan)(guan)(guan)(guan)材(cai)的(de)(de)(de)(de)(de)又一(yi)個(ge)很突出的(de)(de)(de)(de)(de)特(te)點(dian)。 　　施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)方便： 　　由(you)于(yu)聚(ju)(ju)(ju)(ju)乙(yi)烯(xi)雙(shuang)(shuang)(shuang)(shuang)(shuang)(shuang)壁(bi)(bi)(bi)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)重量輕，搬運(yun)和(he)(he)連接都(dou)很方便，所以施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)快(kuai)捷、維護(hu)工(gong)(gong)(gong)(gong)作簡單。在工(gong)(gong)(gong)(gong)期(qi)緊和(he)(he)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)條(tiao)件差的(de)(de)(de)(de)(de)情(qing)況下(xia)，其(qi)優勢更加明顯。 　　摩阻小流(liu)量大(da)(da)： 　　采用聚(ju)(ju)(ju)(ju)乙(yi)烯(xi)為材(cai)料的(de)(de)(de)(de)(de)聚(ju)(ju)(ju)(ju)乙(yi)烯(xi)雙(shuang)(shuang)(shuang)(shuang)(shuang)(shuang)壁(bi)(bi)(bi)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)比(bi)相(xiang)口徑的(de)(de)(de)(de)(de)其(qi)他管(guan)(guan)(guan)(guan)材(cai)可通過更大(da)(da)的(de)(de)(de)(de)(de)流(liu)量。換句(ju)說法，相(xiang)同的(de)(de)(de)(de)(de)流(liu)量要求(qiu)下(xia)，可采用口徑相(xiang)對較小的(de)(de)(de)(de)(de)聚(ju)(ju)(ju)(ju)乙(yi)烯(xi)雙(shuang)(shuang)(shuang)(shuang)(shuang)(shuang)壁(bi)(bi)(bi)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)。 　　良好(hao)的(de)(de)(de)(de)(de)耐(nai)低溫，抗沖(chong)擊性(xing)能(neng)： 　　聚(ju)(ju)(ju)(ju)乙(yi)烯(xi)雙(shuang)(shuang)(shuang)(shuang)(shuang)(shuang)壁(bi)(bi)(bi)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)的(de)(de)(de)(de)(de)脆化(hua)溫度(du)(du)是(shi)-70℃。一(yi)般低溫條(tiao)件下(xia)(-30℃以上)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)時不必采取特(te)殊保(bao)護(hu)措施(shi)(shi)(shi)，冬季施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)方便，而且(qie)，聚(ju)(ju)(ju)(ju)乙(yi)烯(xi)雙(shuang)(shuang)(shuang)(shuang)(shuang)(shuang)壁(bi)(bi)(bi)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)有良好(hao)的(de)(de)(de)(de)(de)抗沖(chong)擊性(xing)。
