MPP管又稱MPP電力電纜保護(hù)管，分為開(kāi)挖型和非開(kāi)挖型，MPP非開(kāi)挖管又稱作MPP頂管或托拉管。MPP管采用改性聚丙烯為主要原材料。具有抗高溫、耐外壓的特點(diǎn)，適用于10KV以下高壓輸電線電纜排管管材。MPP采用改性聚丙烯為主要原材料，是無(wú)須大量挖泥、挖土及破壞路面，在道路、鐵路、建筑物、河床下等特殊地段敷設(shè)管道、電纜等施工工程。與傳統(tǒng)的“挖槽埋管法”相比，非開(kāi)挖電力管工程更適應(yīng)當(dāng)前的環(huán)保要求，去除因傳統(tǒng)施工所造成的塵土飛揚(yáng)、交通阻塞等擾民因素，這一技術(shù)還可以在一些無(wú)法實(shí)施開(kāi)挖作業(yè)的地區(qū)鋪設(shè)管線，如古跡保護(hù)區(qū)、鬧市區(qū)、農(nóng)作物及農(nóng)田保護(hù)區(qū)、高速公路、河流等。管材常用規(guī)格為直徑110mm～中250mm，分為普通型和加強(qiáng)型。普通型適用于開(kāi)挖鋪設(shè)施工和非開(kāi)挖穿越施工埋深小于4M的工程；加強(qiáng)型適用于非開(kāi)挖穿越施工埋深大于4M的工程。四川塑膠MPP定制惹起泄露的緣由較多。如果逾越拉伸或緊縮，則有可以損壞梅花管，構(gòu)成小管分裂，密封掉效。</p><div

MPP管屬于新型產(chǎn)品，很多人不知道它和PE管的區(qū)別，其實(shí)了解MPP和PE管的性質(zhì)，識(shí)別MPP管和非MPP管并不難，先說(shuō)說(shuō)MPP管與PE管的區(qū)別：顏色MPP管一般為橘紅色；而PE管比較常見(jiàn)的一般為黑色或白色。耐高溫MPP管具有耐高溫的特點(diǎn)，管材呈剛性；PE管由于無(wú)法耐高溫，材料呈熱塑性，一般在施工現(xiàn)場(chǎng)就很好分辨。切割面不同MPP電力管具有耐高溫的特點(diǎn)，電力管廠家切割時(shí)不會(huì)分解，切割面光滑平整；而PE管無(wú)法耐高溫，切割時(shí)會(huì)軟化分解，切割面毛糙。聲音辨別熟悉兩種管材的人也可通過(guò)敲擊管材，通過(guò)敲擊聲識(shí)別，MPP非開(kāi)挖電力管由于呈剛性，聲音清脆嘹亮。用途不同MPP管是埋地穿線管，PE管則是給水、灌溉等。 </p><p> mpp電力保護(hù)管，是可以保護(hù)電纜，可以在一些特殊的地段進(jìn)行敷設(shè)，與傳統(tǒng)的埋管法相比，mpp電力管更適應(yīng)于環(huán)保要求，可以解決傳統(tǒng)施工所造成的塵土飛揚(yáng)、交通阻塞的問(wèn)題。這一技術(shù)還可以在一些無(wú)法實(shí)施開(kāi)挖作業(yè)的地區(qū)鋪設(shè)管線，如古跡保護(hù)區(qū)、鬧市區(qū)、農(nóng)作物及農(nóng)田保護(hù)區(qū)、高速公路、河流等。mpp電力電纜保護(hù)管具有抗高溫、耐外壓的特點(diǎn)，適用于高壓輸電線電纜排管管材。城鄉(xiāng)非開(kāi)挖水平定向鉆進(jìn)電力排管工程，及明開(kāi)挖電力排管工程城鄉(xiāng)非開(kāi)挖水平定向鉆進(jìn)下水排污排管工程市政、電信、電力、煤氣、自來(lái)水、熱力等管線工程。具有優(yōu)良的電氣絕緣性。具有較高的熱變形溫度和低溫沖擊性能。抗拉、抗壓性能比HDPE高。質(zhì)輕、光滑、磨擦主力小、可熱熔焊對(duì)接。長(zhǎng)期使用溫度一5～70℃。 MPP電力管的拉伸長(zhǎng)度及緊縮量是根據(jù)閥門(mén)，不銹鋼梅花管截止閥泄露一般分為內(nèi)漏和外漏兩種情況；</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="四川塑膠MPP定制,MPP"
