聚乙烯雙壁波紋管具有怎樣的性能特點

2023-09-18

抗外壓(ya)能(neng)力強： 　　外壁(bi)(bi)(bi)呈(cheng)環形波(bo)紋(wen)(wen)(wen)狀結構，大大增(zeng)強了(le)管(guan)(guan)(guan)(guan)(guan)材(cai)(cai)的(de)(de)(de)(de)(de)環剛度(du)，從而增(zeng)強了(le)管(guan)(guan)(guan)(guan)(guan)道對土壤負荷的(de)(de)(de)(de)(de)抵抗力，在這個(ge)性(xing)能(neng)方(fang)(fang)面，聚(ju)(ju)(ju)乙(yi)(yi)(yi)烯(xi)(xi)(xi)雙(shuang)壁(bi)(bi)(bi)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)與其(qi)(qi)他(ta)(ta)管(guan)(guan)(guan)(guan)(guan)材(cai)(cai)相(xiang)比較(jiao)具有明顯(xian)的(de)(de)(de)(de)(de)優勢。 　　工(gong)程造價(jia)低(di)： 　　在等負荷的(de)(de)(de)(de)(de)條(tiao)件(jian)(jian)下(xia)，聚(ju)(ju)(ju)乙(yi)(yi)(yi)烯(xi)(xi)(xi)雙(shuang)壁(bi)(bi)(bi)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)只需要較(jiao)薄的(de)(de)(de)(de)(de)管(guan)(guan)(guan)(guan)(guan)壁(bi)(bi)(bi)就可(ke)以滿足要求。因此，與同(tong)材(cai)(cai)質規格的(de)(de)(de)(de)(de)實壁(bi)(bi)(bi)相(xiang)管(guan)(guan)(guan)(guan)(guan)比，能(neng)節(jie)約一半左(zuo)右(you)的(de)(de)(de)(de)(de)原(yuan)材(cai)(cai)料，所(suo)以聚(ju)(ju)(ju)乙(yi)(yi)(yi)烯(xi)(xi)(xi)雙(shuang)壁(bi)(bi)(bi)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)造價(jia)也(ye)較(jiao)低(di)。這是該(gai)管(guan)(guan)(guan)(guan)(guan)材(cai)(cai)的(de)(de)(de)(de)(de)又一個(ge)很突出的(de)(de)(de)(de)(de)特點。 　　施(shi)(shi)工(gong)方(fang)(fang)便(bian)： 　　由于聚(ju)(ju)(ju)乙(yi)(yi)(yi)烯(xi)(xi)(xi)雙(shuang)壁(bi)(bi)(bi)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)重量輕，搬運(yun)和(he)(he)連接都(dou)很方(fang)(fang)便(bian)，所(suo)以施(shi)(shi)工(gong)快捷、維(wei)護工(gong)作簡單。在工(gong)期緊和(he)(he)施(shi)(shi)工(gong)條(tiao)件(jian)(jian)差的(de)(de)(de)(de)(de)情況下(xia)，其(qi)(qi)優勢更加明顯(xian)。 　　摩阻小(xiao)流量大： 　　采用(yong)(yong)聚(ju)(ju)(ju)乙(yi)(yi)(yi)烯(xi)(xi)(xi)為(wei)材(cai)(cai)料的(de)(de)(de)(de)(de)聚(ju)(ju)(ju)乙(yi)(yi)(yi)烯(xi)(xi)(xi)雙(shuang)壁(bi)(bi)(bi)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)比相(xiang)口徑的(de)(de)(de)(de)(de)其(qi)(qi)他(ta)(ta)管(guan)(guan)(guan)(guan)(guan)材(cai)(cai)可(ke)通(tong)過更大的(de)(de)(de)(de)(de)流量。換句說法，相(xiang)同(tong)的(de)(de)(de)(de)(de)流量要求下(xia)，可(ke)采用(yong)(yong)口徑相(xiang)對較(jiao)小(xiao)的(de)(de)(de)(de)(de)聚(ju)(ju)(ju)乙(yi)(yi)(yi)烯(xi)(xi)(xi)雙(shuang)壁(bi)(bi)(bi)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)。 　　良好的(de)(de)(de)(de)(de)耐低(di)溫，抗沖擊(ji)性(xing)能(neng)： 　　聚(ju)(ju)(ju)乙(yi)(yi)(yi)烯(xi)(xi)(xi)雙(shuang)壁(bi)(bi)(bi)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)的(de)(de)(de)(de)(de)脆(cui)化溫度(du)是-70℃。一般(ban)低(di)溫條(tiao)件(jian)(jian)下(xia)(-30℃以上)施(shi)(shi)工(gong)時不必采取特殊保護措施(shi)(shi)，冬(dong)季(ji)施(shi)(shi)工(gong)方(fang)(fang)便(bian)，而且，聚(ju)(ju)(ju)乙(yi)(yi)(yi)烯(xi)(xi)(xi)雙(shuang)壁(bi)(bi)(bi)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)有良好的(de)(de)(de)(de)(de)抗沖擊(ji)性(xing)。
