當(dāng)波紋管兩端都受到限制時(shí)，如果波紋管內(nèi)壓力增大至某一臨界值，波紋管就會(huì)產(chǎn)生失穩(wěn)現(xiàn)象。允許位移；對(duì)于工作在壓縮狀態(tài)的波紋管，它的比較大壓縮位移是：波紋管在壓力作用下，壓縮到波紋之間相互彼此接觸時(shí)所能產(chǎn)生的比較大位移值，也稱為結(jié)構(gòu)允許比較大位移，它等于波紋管自由長度與比較大壓縮長度之差。波紋管不產(chǎn)生塑性變形情況下所能獲得的比較大位移稱為波紋管的允許位移。波紋管在實(shí)際工作過程中會(huì)產(chǎn)生殘余變形，殘余變形又稱長久變形或塑性變形，波紋管在力或壓力作用下產(chǎn)生變形，當(dāng)力或壓力卸除后，波紋管不恢復(fù)原始狀態(tài)的現(xiàn)象稱殘余變形，殘余變形通常用波紋管不恢復(fù)原始位置的量來表示又稱零位偏移。

焊縫不得高于國際標(biāo)準(zhǔn)，焊條要求要與管材所用材料相一致，對(duì)于800毫米以上的管材，還要保證內(nèi)外雙面焊接。電熱熔帶的連接就必須要配套，還要檢查管道和熱熔帶是否有損傷，連接的時(shí)候要對(duì)齊和清理雜物，將連接的管道放在地面上20-30公分處，使用熱熔帶將水平對(duì)齊管道的連接部分**的圈住，然后外面再用耐熱帶緊固，焊接要做好冷卻工作。熱收縮管帶需要從一端向另一端逐漸加熱，檢查波紋管兩端是否平整，合攏間隙小于6毫米，將熱縮管穿套在待接管上，打磨粗糙并且擦拭干凈，將兩端對(duì)齊并且固定等。
