<br /> </p> <p> 按模塊裝配方式可分為：立式和臥式（水平式）兩種，立式成型裝置可使模塊上下開合，并且占地面積小、結(jié)構(gòu)緊湊，但模塊更換較困難，特別是大口徑模塊的更換；水平式（又稱為臥式）成型裝置可使模塊水平開合（通常只有大口徑的成型設(shè)備），占地面積較大，但更換模塊比立式方便。而且模塊內(nèi)設(shè)計了冷卻水循環(huán)通道，以水作為冷卻介質(zhì)，大幅度提高了生產(chǎn)的速度。

高密度聚乙烯(HDPE)雙壁波紋管，是一種具有環(huán)狀結(jié)構(gòu)外壁和平滑內(nèi)壁的新型管材，80年代初在德國首先研制成功。管壁截面為雙層結(jié)構(gòu)，其內(nèi)壁光滑平整，外壁等距排列的具有梯形中空結(jié)構(gòu)的管材。公稱直徑（DN）：管材的公稱直徑，分內(nèi)徑系列和外徑系列兩類同時執(zhí)行。環(huán)向彎曲剛度：管道抵抗環(huán)向變形能力的量度，單位KN/㎡。經(jīng)過十多年的發(fā)展和完善，已經(jīng)由單一的品種發(fā)展到完整的產(chǎn)品系列。目前在生產(chǎn)工藝和使用技術(shù)上已經(jīng)十分成熟。由于其優(yōu)異的性能和相對經(jīng)濟的造價，在歐美等發(fā)達(dá)國家已經(jīng)得到了極大的推廣和應(yīng)用。在我國，HDPE雙壁波紋管的推廣和應(yīng)用正處在上升勢態(tài)階段，各項技術(shù)指標(biāo)均達(dá)到使用標(biāo)準(zhǔn)。
