為(wei)常(chang)見的軸向(xiang)式波紋(wen)(wen)管(guan)(guan)(guan)膨脹(zhang)(zhang)(zhang)節，用(yong)在(zai)(zai)管(guan)(guan)(guan)道(dao)(dao)(dao)上進行軸向(xiang)長度補償。為(wei)了防(fang)止超過允許的補償量，在(zai)(zai)波紋(wen)(wen)管(guan)(guan)(guan)兩(liang)端(duan)設置有保(bao)護(hu)拉(la)桿(gan)或保(bao)護(hu)環，在(zai)(zai)與它連(lian)接的兩(liang)端(duan)管(guan)(guan)(guan)道(dao)(dao)(dao)上設置導向(xiang)支架(jia)。另外還有轉(zhuan)角式和(he)橫向(xiang)式膨脹(zhang)(zhang)(zhang)節，可用(yong)來補償管(guan)(guan)(guan)道(dao)(dao)(dao)的轉(zhuan)角變形(xing)和(he)橫向(xiang)變形(xing)。這類(lei)膨脹(zhang)(zhang)(zhang)節的優點(dian)是(shi)節省空間(jian)，節約材料(liao)，便于(yu)標準化和(he)批量生(sheng)產(chan)，缺點(dian)是(shi)壽(shou)命較(jiao)短。波紋(wen)(wen)管(guan)(guan)(guan)膨脹(zhang)(zhang)(zhang)節一般用(yong)于(yu)溫度和(he)壓力不很高、長度較(jiao)短的管(guan)(guan)(guan)道(dao)(dao)(dao)上。隨著波紋(wen)(wen)管(guan)(guan)(guan)生(sheng)產(chan)技術水平的提高，這類(lei)膨脹(zhang)(zhang)(zhang)節的應用(yong)范圍正(zheng)在(zai)(zai)擴(kuo)大。目(mu)前(qian)，波紋(wen)(wen)管(guan)(guan)(guan)膨脹(zhang)(zhang)(zhang)節可用(yong)在(zai)(zai)最高壓力6.0兆帕(pa)的管(guan)(guan)(guan)系(xi)中。
