煤礦井下用鋼絲網骨架塑料復合管在生產的而過程中專業為煤炭作業打造的一種耐高壓管材,中間層是以纏繞鋼絲網為主,聚乙烯本身具有阻燃抗靜電,用專用熱熔膠,通過擠出成型方法復合成一體的管材,對與地下煤炭作業有良好的保護作用。
煤礦井下用鋼絲網骨架塑料復合管根據其不同的用途,也有不同的分類:其中最常見的有:氣體通用管(KMQ)和液體通用管(KML)
氣體通用管 CKMQ)可用于煤礦井下正壓通風、負壓通風、抽放瓦斯等;
液體通用管(KML)可用于煤礦井下供 水排水、噴漿等;
用于煤炭作業的管材還必須擁有較長的工作壽命和耐腐蝕特性,這樣就可以從根本上減少成本,提高管材的運行質量。其中常見的規格有以下幾種:
