梅花管、英文Plumtube。是一種梅花狀的通信管材，又稱梅花管和蜂窩管，剛度好、它主要用于移動、鐵通、聯(lián)通、網(wǎng)通、廣電等通信電纜護(hù)套管。梅花管是以pvc粒子為主要材料加上其他配方經(jīng)過獨特的模具而形成的一種梅花狀的通信管材，又稱梅花管和蜂窩管，此種管材內(nèi)壁光滑，直接可穿光纜，可節(jié)省工時，其結(jié)構(gòu)合理，使用價值高，壽命長。它主要用于移動、鐵通、聯(lián)通、網(wǎng)通、廣電等通信電纜護(hù)套管。梅花管采用多孔一體結(jié)構(gòu)，剛度好，受力均勻。產(chǎn)品內(nèi)壁摩擦系數(shù)小，穿纜輕快，施工簡便易行。具有多個孔位，可預(yù)留管孔，提高通信孔位利用率。 </p><p> 可以采用pvc的七孔梅花管，pvc梅花管可以做到極薄，這樣水泥包封定型沒有任何壓力，內(nèi)壁也達(dá)到光滑，穿線也好，pvc可以很大降低塑料成本，然則施工成本可能有所增加，pvc容易碎裂，尤其是加硬的。那么如果您確定了使用其中一種材質(zhì)的，那么又如何鑒別好壞呢。hdpe純原料的梅花管帶有半透明效果，當(dāng)然也不一定半透明的就是您所需要的，很多時候要考慮的成本很重要，回料的梅花管一樣可以使用，而且還環(huán)保，廢料再利用對于我們來說也是好事兒啊，使用壽命基本不受影響，再看厚薄，厚的就有勁兒，薄的就容易壓癟，環(huán)剛度低。盡可能使用厚的，hdpe七孔梅花管有直管，有盤管，一般說來盤管用料比直管要考究的，因為盤管增韌很重要，如果一折就折，那么肯定就做不成盤管，因此盤管用料要好，故而價格也就偏高，能差5-10元錢每米的價格。要說做盤管，pvc是很難做成盤管的，如果有人說用pvc給您做成盤管，那么很可能帶有欺騙性。pvc不硬化是很軟的，軟就容易癟，硬化了又缺乏韌性。管道的埋設(shè)地溝應(yīng)按設(shè)計要求和施工操作盡可能平直，如溝底不平可鋪上一層細(xì)沙。</p><div

梅花管的根基成型出產(chǎn)工藝航線比擬簡單，平凡狀況下不必要什么原料的準(zhǔn)備工作。出產(chǎn)梅花管時，可直接把粒料透出擠出機料斗中根基成型。梅花管的根基成型出產(chǎn)工藝次序如下：原料開袋考驗質(zhì)量→擠出機吧原料塑化熔融→模具城城管坯→真空定徑套冷卻定徑→真空噴淋冷卻→管材冷卻降溫→牽引→盤卷→考驗質(zhì)量→檢斤入庫。梅花管奇特符合在光纜、電纜、同軸電纜的好多線路同時拽拉和鋪設(shè)，這是因為梅花管將防守層和子管同一在了同時，使得它能夠合意各單孔孔壁相交，致密混雜的個性，當(dāng)鋪設(shè)一個梅花管的時候能夠完結(jié)七個或許五個子管同時鋪設(shè)。七孔梅花管普遍用于電信、廣電、鐵路、部度等通信電力的應(yīng)用。四川七孔梅花管定制廠家</p><p
