WRG flexible waterproof casing

WRG flexible waterproof casing Shandong coal Welcome - Li Li Phone: 13475756709 Description: 1, this figure dimensions are in millimeters count. 2, flexible waterproof casing generally through the walls of the place by vibration or water tight structures required. 3, the sleeve portion of processing is completed, both in its outer wall paint brush again (including primer Zhang Dan or cold base oil). External corrosion is determined by the design. 4, the sleeve through the wall of the wall, in case of non-concrete walls should switch to concrete walls, pouring concrete its scope should fly wing to wing ring diameter (D6) large 200mm, and must be solid casing and poured walls. 5, wearing a tube at the concrete wall thickness not less than 300mm thick or should make one side or both sides of the thick walls. The minimum diameter of the thickened portion should fly wing to wing ring diameter (D6) 200mm 6, is based on the weight of the casing material is 300mm thick and L should be calculated separately. 7, the sleeve member welding materials, materials with A3, T42 welding.
