鋼波紋管的防腐處理方法有哪些?

全體(ti)管銜(xian)接(jie)法(fa)蘭選用(yong)角鋼、鋼板制(zhi)造,波紋板焊(han)接(jie)選用(yong) 對(dui)焊(han)接(jie)頭。緊固件選用(yong)國標中(zhong)的(de)尺度(du)(du)(du)緊固件,其(qi)強度(du)(du)(du)和(he)尺度(du)(du)(du)應知足力學哀求,且不(bu)低于管材強度(du)(du)(du)哀求。墊片(pian)與緊固件般配。螺(luo)栓與螺(luo)母均選用(yong)熱浸(jin)鍍鋅(xin)處(chu)理。

波(bo)紋(wen)為圓形全體(ti)管,選用整管節組(zu)裝、法(fa)蘭螺栓(shuan)銜接。金(jin)屬波(bo)紋(wen)管涵加工后須選用熱鍍鋅等防(fang)腐(fu)處理。選用 鍍鋅鋼板加工的,在加工后有必要(yao)進行二次處理。

金屬(shu)波紋管(guan)涵的檢(jian)(jian)修(xiu)(xiu)項(xiang)目(mu)及檢(jian)(jian)修(xiu)(xiu)方法,金屬(shu)波紋管(guan)涵的機能檢(jian)(jian)測指標(biao)主要(yao)有七項(xiang):外(wai)觀、尺寸(cun)、耐(nai)壓、氣(qi)密(mi)性、靜(jing)態彎曲(qu)、動態彎曲(qu)、爆破。其中(zhong)外(wai)觀、尺寸(cun)、耐(nai)壓和氣(qi)密(mi)性屬(shu)于(yu)出(chu)廠檢(jian)(jian)修(xiu)(xiu)項(xiang)目(mu),型式試驗時(shi)要(yao)求(qiu)七個項(xiang)目(mu)全部進行檢(jian)(jian)修(xiu)(xiu)。

試(shi)(shi)驗時,將軟管試(shi)(shi)件平直放置(zhi),一端安裝帶有(you)排氣閥的堵頭,另一端和試(shi)(shi)壓泵出口管相連接,將水注入管內(nei),排盡空氣,封閉排氣閥,然后緩慢增加壓力至劃定的試(shi)(shi)驗壓力值,保壓5mm后,檢查試(shi)(shi)樣狀況,有(you)無滲漏、零(ling)件損壞(huai)等異(yi)常的失效形式泛起。合格品要求不(bu)答(da)應有(you)滲漏跡象或零(ling)件損壞(huai)等異(yi)常的失效形式泛起。

鋼波紋管耐壓(ya)(ya)(ya)(ya)試(shi)(shi)(shi)(shi)驗又叫(jiao)做強度試(shi)(shi)(shi)(shi)驗,屬于安全機能指標試(shi)(shi)(shi)(shi)驗。試(shi)(shi)(shi)(shi)驗壓(ya)(ya)(ya)(ya)力為(wei)(wei)公稱壓(ya)(ya)(ya)(ya)力的(de)1.5倍,試(shi)(shi)(shi)(shi)驗用(yong)加壓(ya)(ya)(ya)(ya)介質為(wei)(wei)純凈的(de)水,其氯離子含(han)量(liang)不應超過25ppm。每(mei)一支金屬波(bo)紋管涵產品都(dou)要進行耐壓(ya)(ya)(ya)(ya)試(shi)(shi)(shi)(shi)驗。采用(yong)手動的(de)或電動的(de)試(shi)(shi)(shi)(shi)壓(ya)(ya)(ya)(ya)泵加壓(ya)(ya)(ya)(ya),壓(ya)(ya)(ya)(ya)力觀測通常可用(yong)1.5--4倍試(shi)(shi)(shi)(shi)驗壓(ya)(ya)(ya)(ya)氣力程的(de)1.5級以上壓(ya)(ya)(ya)(ya)力表,或等同功效(xiao)的(de)壓(ya)(ya)(ya)(ya)力測試(shi)(shi)(shi)(shi)儀(yi)器。
