耐(nai)壓(ya)(ya)(ya)(ya)試(shi)(shi)(shi)(shi)(shi)(shi)驗(yan)又稱(cheng)強度試(shi)(shi)(shi)(shi)(shi)(shi)驗(yan)，屬于安全性能指標試(shi)(shi)(shi)(shi)(shi)(shi)驗(yan)。試(shi)(shi)(shi)(shi)(shi)(shi)驗(yan)壓(ya)(ya)(ya)(ya)力(li)(li)為(wei)公稱(cheng)壓(ya)(ya)(ya)(ya)力(li)(li)的(de)(de)(de)1.5倍(bei)，試(shi)(shi)(shi)(shi)(shi)(shi)驗(yan)用加壓(ya)(ya)(ya)(ya)介質(zhi)為(wei)純凈的(de)(de)(de)水，其氯離子含量不(bu)應(ying)超過25ppm。每一(yi)支產品都要(yao)進行耐(nai)壓(ya)(ya)(ya)(ya)試(shi)(shi)(shi)(shi)(shi)(shi)驗(yan)。采用手(shou)動(dong)的(de)(de)(de)或電動(dong)的(de)(de)(de)試(shi)(shi)(shi)(shi)(shi)(shi)壓(ya)(ya)(ya)(ya)泵加壓(ya)(ya)(ya)(ya)，壓(ya)(ya)(ya)(ya)力(li)(li)觀測(ce)通常可用1.5--4倍(bei)試(shi)(shi)(shi)(shi)(shi)(shi)驗(yan)壓(ya)(ya)(ya)(ya)力(li)(li)量程(cheng)的(de)(de)(de)1.5級以上壓(ya)(ya)(ya)(ya)力(li)(li)表，或等(deng)同(tong)功效(xiao)(xiao)的(de)(de)(de)壓(ya)(ya)(ya)(ya)力(li)(li)測(ce)試(shi)(shi)(shi)(shi)(shi)(shi)儀(yi)器。試(shi)(shi)(shi)(shi)(shi)(shi)驗(yan)時，將(jiang)軟管(guan)(guan)(guan)試(shi)(shi)(shi)(shi)(shi)(shi)件(jian)(jian)平直放置，一(yi)端安裝帶有排氣閥的(de)(de)(de)堵頭，另一(yi)端和試(shi)(shi)(shi)(shi)(shi)(shi)壓(ya)(ya)(ya)(ya)泵出口管(guan)(guan)(guan)相連(lian)接，將(jiang)水注入管(guan)(guan)(guan)內，排盡空氣，關閉排氣閥，然后緩慢增加壓(ya)(ya)(ya)(ya)力(li)(li)至規定(ding)的(de)(de)(de)試(shi)(shi)(shi)(shi)(shi)(shi)驗(yan)壓(ya)(ya)(ya)(ya)力(li)(li)值，保壓(ya)(ya)(ya)(ya)5mm后，檢(jian)查試(shi)(shi)(shi)(shi)(shi)(shi)樣(yang)狀況，有無滲漏、零件(jian)(jian)損壞(huai)等(deng)異常的(de)(de)(de)失(shi)效(xiao)(xiao)形(xing)式出現。合(he)格(ge)品要(yao)求不(bu)允(yun)許有滲漏跡象或零件(jian)(jian)損壞(huai)等(deng)異常的(de)(de)(de)失(shi)效(xiao)(xiao)形(xing)式出現。

　　檢驗項目及檢驗方法金屬波紋管的(de)性能檢(jian)(jian)測指標(biao)主要有七項(xiang)(xiang):外觀(guan)、尺(chi)寸、耐(nai)壓(ya)、氣密性、靜(jing)態(tai)彎曲(qu)、動態(tai)彎曲(qu)、爆破(po)。其中(zhong)外觀(guan)、尺(chi)寸、耐(nai)壓(ya)和氣密性屬于出廠檢(jian)(jian)驗項(xiang)(xiang)目(mu)，型式(shi)試驗時要求七個項(xiang)(xiang)目(mu)全部進(jin)行(xing)檢(jian)(jian)驗。本文主要對耐(nai)壓(ya)、氣密性、靜(jing)態(tai)彎曲(qu)、動態(tai)彎曲(qu)和爆破(po)等五個項(xiang)(xiang)目(mu)進(jin)行(xing)論述。
