為(wei)常見的軸向(xiang)式波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)膨脹(zhang)(zhang)節，用(yong)在(zai)管(guan)(guan)(guan)道(dao)(dao)上(shang)進行軸向(xiang)長度補償(chang)。為(wei)了防止超(chao)過允許的補償(chang)量(liang)，在(zai)波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)兩端設(she)置有保護拉桿或(huo)保護環，在(zai)與它連(lian)接的兩端管(guan)(guan)(guan)道(dao)(dao)上(shang)設(she)置導向(xiang)支架。另外(wai)還(huan)有轉角(jiao)式和橫(heng)向(xiang)式膨脹(zhang)(zhang)節，可(ke)用(yong)來補償(chang)管(guan)(guan)(guan)道(dao)(dao)的轉角(jiao)變形和橫(heng)向(xiang)變形。這類膨脹(zhang)(zhang)節的優(you)點是節省空間，節約材料(liao)，便于標準化和批量(liang)生(sheng)產，缺點是壽命較短(duan)。波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)膨脹(zhang)(zhang)節一般用(yong)于溫度和壓力不很高(gao)、長度較短(duan)的管(guan)(guan)(guan)道(dao)(dao)上(shang)。隨著波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)生(sheng)產技術水(shui)平的提高(gao)，這類膨脹(zhang)(zhang)節的應用(yong)范圍正在(zai)擴大。目前，波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)膨脹(zhang)(zhang)節可(ke)用(yong)在(zai)最高(gao)壓力6.0兆帕(pa)的管(guan)(guan)(guan)系(xi)中。
