Flexible water-proof bushing is mainly used in the pipeline through the walls by vibration or tight water-proof requirements of building the hardware fittings, general production enterprises is according to the Academy of building research, development and design of S312, 02S404 standard atlas manufacturing. Flexible waterproof wall bushing at the walls, such as in the event of non concrete should be switched to concrete walls, and must be sleeve solidification on the inner wall, and the casting range should be BizArt ring diameter (D5) 200 must sleeve is fixed on the inner wall. Flexible waterproof casing is widely used in construction, chemical, steel, water, sewage treatment and other units.
Generally in the water tank to use casing, it is the channel to the pool of the channel. But the ordinary casing is very difficult to seal, so from the casing and the pipeline between the leakage, the casing and the wall between the wall is also easy to leak. Only use the waterproof casing to solve the leakage between the casing and the wall, but also can not solve the seal between the casing and the pipe, flexible waterproof casing can solve two problems.
Materials and standard for the installation of flexible waterproof casing:
1 and when to meet the water is corrosive medium, waterproof casing pipe sealing ring and the sealing material and sealing paste needs to use the resistance to corrosive materials such as PTFE lining rubber, avoid medium contact surface corrosion effects.
2, the general situation of flexible waterproof casing packing materials for asphalt hemp, polystyrene board, PVC foam board.
3, sealing paste: Poly sulfur seal, polyurethane sealing paste.
4, welding structure size tolerance and form position tolerance according to JB/T5000.3-1998 implementation. Welding manual welding, welding electrode type E4303, grade J422. The basic shape of weld in size according to GB985-88 implementation.
5,the weight of the flexible waterproof casing L=300 calculation, such as the wall thickness is greater than 300, should be calculated separately.
Our waterproof casing will provide you with installation instructions for use, can also refer to the 02s404 waterproof casing standard atlas construction generally in for, if there is other issues on the waterproof casing can call HuanZhong sales we will give you a satisfactory pipeline solution.
