為(wei)常見的軸(zhou)向式(shi)波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)膨脹節(jie)(jie),用(yong)在(zai)管(guan)(guan)(guan)(guan)道(dao)上進(jin)行軸(zhou)向長度(du)補償(chang)。為(wei)了防止(zhi)超過(guo)允許的補償(chang)量,在(zai)波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)兩(liang)端設(she)置(zhi)有(you)保(bao)護拉桿或保(bao)護環,在(zai)與它(ta)連接的兩(liang)端管(guan)(guan)(guan)(guan)道(dao)上設(she)置(zhi)導向支架。另外還有(you)轉角(jiao)式(shi)和(he)(he)橫向式(shi)膨脹節(jie)(jie),可(ke)用(yong)來補償(chang)管(guan)(guan)(guan)(guan)道(dao)的轉角(jiao)變形和(he)(he)橫向變形。這類膨脹節(jie)(jie)的優點是(shi)節(jie)(jie)省空(kong)間,節(jie)(jie)約材料,便(bian)于標準化和(he)(he)批量生(sheng)產(chan),缺點是(shi)壽(shou)命較短。波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)膨脹節(jie)(jie)一般(ban)用(yong)于溫(wen)度(du)和(he)(he)壓力不很高、長度(du)較短的管(guan)(guan)(guan)(guan)道(dao)上。隨(sui)著波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)生(sheng)產(chan)技術水(shui)平(ping)的提高,這類膨脹節(jie)(jie)的應用(yong)范(fan)圍正(zheng)在(zai)擴(kuo)大。目前,波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)膨脹節(jie)(jie)可(ke)用(yong)在(zai)最高壓力6.0兆帕的管(guan)(guan)(guan)(guan)系中(zhong)。
