S312 flexible steel waterproof casing related introduction
S312 type flexible waterproof and flexible waterproof casing pipe generally applicable for pipe through the wall of a vibration or structures requiring strict waterproof casing parts processing is completed, in its outer wall all brush priming again (primer ZhangDan or cold priming oil). The outer corrosion is determined by the design. Casing wall in the wall, in case of the concrete wall should be switched to the concrete wall, the scope of concreting shall be colorful ring (D6) 200 mm in diameter, and must be poured casing solid and walls.Wear in the concrete wall thickness shall be not less than 300 mm of otherwise should make more side wall thickening, or both sides. Increasing the diameter of the part minimum colorful ring diameter of 200 mm (D6). Casing material weight is calculated on wall thickness value is 300 mm L, such as wall thickness is greater than 300 mm should be calculated separately.
