液壓成形波紋管液壓成形是波紋管的常用成形方法。運(yùn)用在管坯中的液體壓力，是管坯在限制環(huán)中脹形，直到沿環(huán)向出現(xiàn)屈服，然后再壓縮管坯到所需的長(zhǎng)度。小直徑波紋管多采用這種方法⑵ 滾壓成形波紋管滾壓成形工藝主要用于加工大型波紋管，是依靠設(shè)在管坯中的成形輪的滾壓成形，可以單波滾制成形，有的裝置亦可一次成數(shù)個(gè)波紋。2. 機(jī)械脹形波紋管運(yùn)用在管坯內(nèi)部擴(kuò)脹的胎具，逐個(gè)地脹壓成波紋，初步成形后，再用內(nèi)外錕精壓定制。3.焊接成形波紋管對(duì)于波高過(guò)大或波形特殊的波紋管，多采用沖壓焊接工藝。當(dāng)波高超過(guò)限度時(shí)，材料延伸率已不允許采用整體成形工藝，或因波形復(fù)雜，整體成形很困難時(shí)也多采用焊接成形。這類波紋管因?yàn)椴荒艹惺軆?nèi)壓，不太適用于作膨脹節(jié)的柔性段。4. 沉積成形波紋管該工藝是運(yùn)用電沉積方法將波紋管材料沉積到芯模上，然后將芯模熔蝕。這種波紋管材料是一種十分柔軟的純鎳金屬材料，且是無(wú)孔的，所以，能耐高真空，并可進(jìn)行焊接。膨脹節(jié)柔性段不宜用這種波紋管，由于成本太高，而且只限于鎳材。</p><p> HDPE管是一種具有環(huán)狀波紋結(jié)構(gòu)外壁和平滑內(nèi)壁的新型塑料管材，由于管道規(guī)格不同，管壁結(jié)構(gòu)也有差別。根據(jù)管壁結(jié)構(gòu)的不同，HDPE管可分為雙壁波紋管和纏繞增強(qiáng)管兩種類型。目前在生產(chǎn)工藝和使用技術(shù)上已經(jīng)十分成熟，在歐美等地區(qū)已經(jīng)得到了很大的推廣和應(yīng)用。有著良好的環(huán)剛度和良好的強(qiáng)度與韌性，重量輕、耐沖擊性強(qiáng)、不易破損等特點(diǎn)，且運(yùn)輸安裝方便。管道主要運(yùn)用橡膠圈承插連接（也可采用熱縮帶連接）。因?yàn)殡p壁波紋管的特殊的波紋管壁結(jié)構(gòu)設(shè)計(jì)，使得該管在同樣直徑和達(dá)到同樣環(huán)剛度的條件下，用料（HDPE）比較省。
