濱電四期熱網工程首條管線沖管完成
4月8日16:40分，浙能濱電四期熱網工(gong)程首條管(guan)線(xian)沖管(guan)結(jie)束，標志著該工(gong)程首個重要節點順利完成。
據了(le)解，濱電四期熱網(wang)工程于2020年12月(yue)8日核準，總(zong)投資3.12億元(yuan)，主要建設(she)內容為鋪(pu)設(she)熱力(li)管(guan)(guan)(guan)(guan)(guan)網(wang)和壓(ya)(ya)(ya)縮空氣管(guan)(guan)(guan)(guan)(guan)網(wang)。熱力(li)低(di)壓(ya)(ya)(ya)管(guan)(guan)(guan)(guan)(guan)線(xian)長約(yue)14.26千(qian)米，設(she)計壓(ya)(ya)(ya)力(li)1.2兆帕；熱力(li)中壓(ya)(ya)(ya)管(guan)(guan)(guan)(guan)(guan)線(xian)長約(yue)6.88千(qian)米，設(she)計壓(ya)(ya)(ya)力(li)3.4兆帕；壓(ya)(ya)(ya)縮空氣管(guan)(guan)(guan)(guan)(guan)線(xian)長約(yue)5.76千(qian)米，設(she)計壓(ya)(ya)(ya)力(li)1.0兆帕。本次沖管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)線(xian)為該(gai)工程9號熱力(li)低(di)壓(ya)(ya)(ya)管(guan)(guan)(guan)(guan)(guan)，管(guan)(guan)(guan)(guan)(guan)道管(guan)(guan)(guan)(guan)(guan)徑超(chao)1米，地埋(mai)管(guan)(guan)(guan)(guan)(guan)外套(tao)管(guan)(guan)(guan)(guan)(guan)外徑將(jiang)近(jin)1.5米，長度(du)約(yue)為2.4千(qian)米。管(guan)(guan)(guan)(guan)(guan)線(xian)沖管(guan)(guan)(guan)(guan)(guan)采用對熱網(wang)管(guan)(guan)(guan)(guan)(guan)道影響(xiang)小、操作更加安全(quan)的蓄能式(shi)吹掃方式(shi)，連續吹掃6次，總(zong)共持(chi)續約(yue)4小時。
該(gai)工程計劃(hua)于(yu)2022年6月竣(jun)工投產，項目投運后可有(you)效(xiao)緩解濱電現有(you)6號管線供熱(re)壓力(li)，為印染集聚“五大(da)組團”供熱(re)提供有(you)力(li)的保障。
