鋼波紋管使用(yong)(yong)(yong)(yong)壽(shou)命長,是選(xuan)用(yong)(yong)(yong)(yong)鋼管熱浸(jin)鍍(du)鋅,所以(yi)使用(yong)(yong)(yong)(yong)壽(shou)命長,壽(shou)命為80-100年,在腐蝕性特別大的環境下使用(yong)(yong)(yong)(yong)時,選(xuan)用(yong)(yong)(yong)(yong)表里(li)外表瀝清附層的鋼波紋管,可在原使用(yong)(yong)(yong)(yong)壽(shou)命基礎上(shang)提高(gao)約20年以(yi)上(shang)。
鋼波紋管嘆為觀止的原因
施(shi)工(gong)(gong)方便(bian)(bian):鋼(gang)波(bo)紋管涵是(shi)選用套(tao)筒或法(fa)蘭辦(ban)法(fa)銜接,而且(qie)能夠根據需要定長度,即(ji)便(bian)(bian)是(shi)非(fei)熟練工(gong)(gong)也(ye)能夠操作,施(shi)工(gong)(gong)以少數(shu)的手工(gong)(gong)操作,可(ke)在短(duan)(duan)時間內完(wan)成(cheng),既方便(bian)(bian)又(you)方便(bian)(bian)。經(jing)濟(ji)性:銜接辦(ban)法(fa)簡便(bian)(bian),可(ke)縮短(duan)(duan)工(gong)(gong)期。
波紋(wen)涵管用(yong)洛氏(shi)硬度計能夠丈量從軟到(dao)硬的各種不(bu)同(tong)材料,這是(shi)因為(wei)它選用(yong)了不(bu)同(tong)的壓頭(tou)(tou)和載荷,組成各種不(bu)同(tong)的洛氏(shi)硬度標(biao)(biao)尺,如HRA、HRB、HRC等(deng)。一般出產以(yi)HRC(用(yong)120度金剛石(shi)圓錐(zhui)體作壓頭(tou)(tou),載荷為(wei)1500N)用(yong)得多,波紋(wen)涵管硬度值(zhi)的標(biao)(biao)注辦法與布氏(shi)硬度相同(tong),硬度值(zhi)的有用(yong)規模為(wei)20~70HRC。為(wei)保證中心(xin)不(bu)留空(kong)地,應在兩接頭(tou)(tou)端頭(tou)(tou)處做好符號。做好后要用(yong)膠帶包裹緊密,以(yi)防漏漿(jiang)。
1.搬運(yun)到(dao)現場的鋼(gang)波(bo)紋管要會集堆(dui)積(ji)整齊,不能在鋼(gang)波(bo)紋管上踐(jian)踏(ta)。
2.鋼(gang)波紋管要(yao)掩(yan)蓋(gai)維護,避免風吹(chui)雨淋使其提早老化。
3.切開鋼波(bo)紋管要平(ping)直,不(bu)能切成(cheng)斜口。
4.鋼波紋管(guan)接(jie)頭的辦法:鋼波紋管(guan)接(jie)頭處要外包(bao)0.3米長的大號鋼波紋管(guan),而且兩端頭要對半擰緊,中心不得留有空(kong)地。
5.鋼波紋管方位定位要,尤其是靠近接頭的部位,鋼波紋管定位鋼筋間距為0.5米,不能短少。//hanihanbj.com/
