Flexible waterproof bushing or it is rigid waterproof bushing is to be crossed in order to pipeline to have vibration or have the hardware fittings of the building building metope that strict moistureproof needs completely, common see in engineering construction. Chemical plant. Steel. Drinking water. Waste water treatment and other enterprises. Moisture-proof casing must go to see the overall strength of the manufacturer. glory belongs to the past, hard work to create the future, only with a hundred times of diligence, stronger product quality and the best business to return your new and old users believe and love, we will continue to uphold the "consumer above all. Quality above all "standard, to" the completion of the consumer is our success "for the purpose of service, dedicated to new customers to give first-class equipment and sound service projects, in the rapid development of social and economic trends hand in hand, together with the trend of development.

1. Be familiar with engineering drawings carefully and analyze how to manufacture embedded casing for equipment before producing and manufacturing waterproof casing.

2. Water supply and drainage waterproof casing should be paid attention to in the production and manufacturing, and the rigid waterproof casing equipment should be supported by the pipe and wall. Beam. Column to face flat.

3. The rigid waterproof bushing shall be welded thoroughly near the sealing wing ring.

4. The inclination of rigid waterproof casing pipes should be symmetrical without inverted slope, and the inclination of flat roof inlet and outlet pipes should be as large as possible.

5. Check whether all rigid waterproof casing pipes have gaps. Is there any sand hole? Is the wall thickness thin and symmetrical?

6. Rigid waterproof casing pipe should be investigated before use. Water injection and surface water flush root by root check whether there is a gap. There are no sand holes.

7. Check that all socket sockets are in time. Firmness. Compactness.

8. Seismic support shall be set for pipeline equipment according to the construction acceptance standard.

9. Judge the length of waterproof casing according to the construction plan design drawing, 304 seamless pipe surface drawing and its construction elevation. Then according to the water supply and drainage general plan and construction drawings, and in accordance with the building atlas to produce.

10. In the production and manufacture of waterproof sleeve, the thickness of the wing ring and waterproof sleeve should meet the provisions, the wing ring of waterproof sleeve should be welded on both sides, and the welding is smooth, smooth, smooth, no welding tumor, no bubbles, no cracks and other conditions. After welding, welding scar processing neat, brush twice on the anti-corrosion paint. In the equipment, both sides of the waterproof casing should be clamped and fixed firmly on the three sides of the building steel bar, and can not be tilted.
