在勤奋的磨石上迸发软式透水管

才能的火花，常常在勤奋的磨石上迸发。莱芜市金利源工程材料有限公司软式透水管，弹簧钢丝经过专业设备先外敷pvc塑料皮，再经过设备形成弹簧线圈，后经过设备缠上丙纶丝，经过加热，设备牵引出来就可形成成品透水管。过滤层: 不织布过滤层。软式透水管和被覆材料：经纱使用高强力尼龙纱，纬纱使用特殊纤维。接著材料：特殊强力 P.V.C接著剂。以可靠便利为原则， 50mm软式透水管可根据隧道环向长度生产与纵向100mm软式透水管长度6-30m连接设有配套的直通、三通接头，可以方便地进行连接。内衬钢线: 高强力弹簧硬钢丝，经磷酸防锈处理，外被覆 P.V.C(电阻加热法)。
To spark, often burst in hard stone. Laiwu Jinliyuan Engineering Materials Co., Ltd. soft permeable pipe, spring steel wire through professional equipment with PVC plastic skin, after equipment form the spring coil, after equipment around polypropylene fiber silk, after heating, pulling out device can form the finished water pipe. The filtering layer: non-woven filter layer. Soft permeable pipe and coated materials: warp using high strength nylon yarn, weft used special fiber. Adhesive materials: special strength of P.V.C adhesive. With reliable convenience principle, 50mm soft permeable pipe according to the tunnel circumferential length production and vertical 100mm soft permeable pipe length 6-30m connection through, with supporting the three joints, can be conveniently connected. The inside lining steel line: high strength spring hard wire, the phosphate anti-rust treatment, the outer coating of P.V.C (electric resistance heating method).
