自應(ying)力鋼(gang)筋混凝土壓(ya)力管(guan)(guan)(guan)（RCCP管(guan)(guan)(guan)）有平口式管(guan)(guan)(guan)和承(cheng)插式管(guan)(guan)(guan)兩種，已成功地(di)用(yong)于輸送(song)(song)水、煤(mei)(mei)氣和熱電廠粉煤(mei)(mei)灰等(deng)。它與鑄鐵管(guan)(guan)(guan)相比有下列優點：剛性(xing)(xing)好(hao)，據介紹(shao)，這種管(guan)(guan)(guan)道在地(di)下可使用(yong)80年以(yi)上；不(bu)導電，能(neng)避免雜散電流對管(guan)(guan)(guan)線的腐(fu)蝕；熱導率低，外界溫度變化(hua)對管(guan)(guan)(guan)內影響小(xiao)(xiao)；長(chang)期輸水內表面(mian)(mian)不(bu)長(chang)銹瘤，通水能(neng)力不(bu)變；有裂(lie)縫閉合和愈(yu)合能(neng)力，若出現寬度小(xiao)(xiao)于0.25mm裂(lie)紋，在自壓(ya)應(ying)力作(zuo)用(yong)下能(neng)閉合，通常(chang)仍可作(zuo)壓(ya)力為(wei)0.6MPa以(yi)內的輸水管(guan)(guan)(guan)使用(yong)；鋪設簡便；接(jie)頭(tou)密(mi)封(feng)性(xing)(xing)好(hao)，使用(yong)可靠；價格(ge)便宜。缺點是：自重大；性(xing)(xing)脆、易斷；當輸送(song)(song)含有面(mian)(mian)體(ti)顆粒(li)的介質時，耐磨性(xing)(xing)不(bu)及鑄鐵管(guan)(guan)(guan)。RCCP管(guan)(guan)(guan)的參考(kao)標準有AWWA C302、AWWA C303等(deng)。
