鋼波(bo)(bo)紋涵管的(de)特(te)征強度(du)高，由于其(qi)獨特(te)的(de)波(bo)(bo)紋結構使(shi)其(qi)比同口徑(jing)的(de)水泥管耐壓(ya)強度(du)大15倍以上(shang)。運(yun)(yun)輸方便，鋼波(bo)(bo)紋涵管的(de)重量只有同口徑(jing)水泥管的(de)1/10到1/5，即(ji)使(shi)在窄(zhai)的(de)場所沒有運(yun)(yun)輸設備，人(ren)工也可運(yun)(yun)輸。
使用壽命長，鋼波紋涵管是采用鋼管熱(re)浸鍍鋅，所以使(shi)用壽(shou)命(ming)長(chang)，壽(shou)命(ming)為80-100年(nian)，在腐蝕性特別大的環境下使(shi)用時，采用內外表面瀝清附層的鋼制波紋(wen)管，可在原使(shi)用壽(shou)命(ming)基(ji)礎(chu)上提高約20年(nian)以上。
施(shi)工(gong)(gong)方便(bian)：波(bo)紋管涵是(shi)采用套筒(tong)或法蘭方式連接(jie)，而且(qie)可(ke)以根據需要定制長度，即使(shi)是(shi)非熟練工(gong)(gong)也可(ke)以操(cao)作(zuo)，施(shi)工(gong)(gong)以少量的手工(gong)(gong)操(cao)作(zuo)，可(ke)在短時間內完成，既(ji)快捷又方便(bian)。優良的經(jing)濟性：連接(jie)方式簡便(bian)，可(ke)縮短工(gong)(gong)期。
波紋(wen)(wen)(wen)管(guan)涵也叫金屬波紋(wen)(wen)(wen)管(guan)涵或(huo)鋼制波紋(wen)(wen)(wen)涵管(guan)，是(shi)指鋪埋在公(gong)路，鐵路下面的(de)涵洞用(yong)螺紋(wen)(wen)(wen)波紋(wen)(wen)(wen)管(guan)，它是(shi)由波形(xing)金屬板卷制成(cheng)或(huo)用(yong)半圓(yuan)波形(xing)鋼片(pian)拼制成(cheng)的(de)圓(yuan)形(xing)波紋(wen)(wen)(wen)管(guan)，應用(yong)于公(gong)路，鐵路，小橋，通道(dao)，擋土墻以及各種礦場，巷道(dao)擋墻支護等工程中的(de)涵洞（管(guan)）。

波紋(wen)管(guan)涵是與(yu)鋼筋混凝土管(guan)涵相比，具有管(guan)節薄，重量輕，便于(yu)運(yun)輸存放，施工工藝簡單，組裝快速，工期(qi)短(duan)等優點(dian)。
建筑波(bo)紋(wen)管時，可根據需要(yao)隨意組裝成任(ren)何長(chang)度，必要(yao)時，管節(jie)還可拆除(chu)，遷(qian)往(wang)別(bie)處修建，在缺乏砂石材料(liao)地(di)區(qu)或地(di)基(ji)承載力(li)較低的地(di)區(qu)，波(bo)紋(wen)管涵(han)的優越性(xing)更為顯(xian)著。
鋼(gang)波紋(wen)(wen)涵(han)管在(zai)國(guo)外(wai)的(de)(de)(de)公路、鐵(tie)路和房屋(wu)建工(gong)(gong)程中(zhong)早已(yi)被方(fang)泛采(cai)用，一些發達 不僅設(she)有制造(zao)波紋(wen)(wen)管節(jie)的(de)(de)(de)工(gong)(gong)廠，而且有些 發布了波紋(wen)(wen)管涵(han)的(de)(de)(de)設(she)計與(yu)施工(gong)(gong)規(gui)范或規(gui)程。我(wo)國(guo)解放前(qian)公路、鐵(tie)路部門(men)也曾使用過(guo)國(guo)外(wai)進口的(de)(de)(de)波紋(wen)(wen)管管節(jie)。目前(qian)我(wo)國(guo)已(yi)有專(zhuan)門(men)生產(chan)波紋(wen)(wen)管涵(han)的(de)(de)(de)工(gong)(gong)廠，鑒于這種管涵(han)的(de)(de)(de)許多優點，我(wo)國(guo)鋼(gang)材產(chan)量(liang)已(yi)跨居世界前(qian)列，在(zai)我(wo)國(guo)推廣應用波紋(wen)(wen)管涵(han)的(de)(de)(de)前(qian)景是非(fei)常廣闊的(de)(de)(de)。
鋼波紋涵(han)管(guan)不少(shao)機器零件(jian)(jian)，如(ru)沖(chong)(chong)床的(de)連桿、鍛(duan)錘的(de)錘頭、火車掛鉤、沖(chong)(chong)模等，在工作(zuo)時(shi)要承受沖(chong)(chong)擊載(zai)荷(he)、如(ru)果仍用靜載(zai)荷(he)作(zuo)用下的(de)強度限指(zhi)標(biao)來進行(xing)設計計算，就不能保證這(zhe)些零件(jian)(jian)工作(zuo)時(shi)的(de)安全(quan)性，必須同時(shi)考慮材料的(de)韌性。波紋涵(han)管(guan)沖(chong)(chong)擊韌性波紋涵(han)管(guan)沖(chong)(chong)擊韌性是指(zhi)材料抵抗(kang)沖(chong)(chong)擊載(zai)荷(he)的(de)能力(li)。
鋼(gang)(gang)波(bo)紋涵管(guan)(guan)(guan)出廠(chang)時，涵管(guan)(guan)(guan)及配件均(jun)經過熱浸鍍(du)鋅(xin)處理，鍍(du)鋅(xin)層平(ping)均(jun)厚度(du)(du)(du)大于84μm，在沒有(you)亂石沖刷的情況(kuang)下(xia)，它(ta)的鍍(du)鋅(xin)層就可防(fang)止銹蝕。目前內(nei)涵管(guan)(guan)(guan)出廠(chang)前，根據(ju)鋼(gang)(gang)管(guan)(guan)(guan)管(guan)(guan)(guan)壁每年蝕耗厚度(du)(du)(du)0.01-0.03mm，都(dou)比(bi)外涵管(guan)(guan)(guan)做的要保(bao)守，比(bi)正常管(guan)(guan)(guan)壁厚度(du)(du)(du)增加了0.5mm，可提高使用壽命，而且涵管(guan)(guan)(guan)運至施(shi)工現場后，工地涂涮兩(liang)遍(bian)瀝(li)青(qing)，瀝(li)青(qing)涂層厚度(du)(du)(du)達到0.3-0.5mm。
并且根據內車輛超載運輸的實際情況，還對YTHG鋼波紋涵管的技術參數（波距、波深、壁厚）進行了調整，增大了涵管在內使用的保險系數。以上幾種措施即可滿足使用要求，使用壽命完全能適合公路的需求，更能滿足受流石沖刷的涵洞，確保流石對涵管管壁的沖擊。//hanihanbj.com/
