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(re)網(wang)工程(cheng)首條管(guan)線沖管(guan)結束，標志著該工程(cheng)首個重要節點順利完成。
據了解，濱電四期熱(re)(re)(re)網工(gong)程(cheng)(cheng)于(yu)2020年(nian)12月(yue)8日核準，總(zong)投資(zi)3.12億元，主(zhu)要建設內容(rong)為(wei)(wei)鋪設熱(re)(re)(re)力(li)(li)管(guan)(guan)(guan)網和壓(ya)(ya)縮(suo)空氣管(guan)(guan)(guan)網。熱(re)(re)(re)力(li)(li)低(di)壓(ya)(ya)管(guan)(guan)(guan)線(xian)長約(yue)(yue)14.26千(qian)(qian)米，設計壓(ya)(ya)力(li)(li)1.2兆(zhao)帕；熱(re)(re)(re)力(li)(li)中(zhong)壓(ya)(ya)管(guan)(guan)(guan)線(xian)長約(yue)(yue)6.88千(qian)(qian)米，設計壓(ya)(ya)力(li)(li)3.4兆(zhao)帕；壓(ya)(ya)縮(suo)空氣管(guan)(guan)(guan)線(xian)長約(yue)(yue)5.76千(qian)(qian)米，設計壓(ya)(ya)力(li)(li)1.0兆(zhao)帕。本次(ci)沖管(guan)(guan)(guan)管(guan)(guan)(guan)線(xian)為(wei)(wei)該(gai)工(gong)程(cheng)(cheng)9號(hao)熱(re)(re)(re)力(li)(li)低(di)壓(ya)(ya)管(guan)(guan)(guan)，管(guan)(guan)(guan)道(dao)管(guan)(guan)(guan)徑(jing)超1米，地埋管(guan)(guan)(guan)外套管(guan)(guan)(guan)外徑(jing)將近1.5米，長度約(yue)(yue)為(wei)(wei)2.4千(qian)(qian)米。管(guan)(guan)(guan)線(xian)沖管(guan)(guan)(guan)采(cai)用(yong)對熱(re)(re)(re)網管(guan)(guan)(guan)道(dao)影響小(xiao)、操作更加安全(quan)的蓄(xu)能(neng)式吹(chui)掃(sao)方式，連續吹(chui)掃(sao)6次(ci)，總(zong)共(gong)持續約(yue)(yue)4小(xiao)時。
該工(gong)程計劃于(yu)2022年6月竣工(gong)投產，項目投運后可有效緩(huan)解(jie)濱電現有6號(hao)管線(xian)供熱壓(ya)力，為印染集聚“五大組團”供熱提供有力的保障。
