Product introduction：

Stainless steel rigid waterproof casing pipe is made of 304 stainless steel or 316L stainless steel raw materials, both ends should be mechanically cut (such as, with toothless saw, etc.), stainless steel rigid waterproof casing pipe is mainly used in a variety of corrosive media in the pipeline, such as chemical pipeline and chemical reaction pool, corrosive sewage treatment pipeline. ZhongYuan firmly believe that "every process we touch, we will improve", Zhongyuan valve fittings reminds New York friends that this information is helpful for choosing Chinese products: Generally, the material is selected according to the requirements of customers. 304 is a kind of universal stainless steel, which has good high temperature resistance. Generally, the temperature is less than 650℃.304 stainless steel has excellent corrosion resistance and corrosion resistance between grains. Inspiring the world through innovation, Zhongyuan valve fittings reminds New York friends to understand this information: Of course, if the requirements are more strict, you can also use 316L stainless steel to produce waterproof sleeve, 316L due to the addition of Mo, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength is particularly good, can be used under harsh conditions; Excellent work hardening (non-magnetic), users can choose according to their actual needs.

Product feature：

1. When the water surface is a corrosive medium, plugging materials can be used to seal the gaps. For details, see 02S404 National Standard Atlas "Flexible waterproof casing pipe (Type B) Installation Drawing";

2. If non-concrete walls are encountered at the place where the casing goes through the wall, concrete walls should be partially used, and the pouring range should be 200 larger than the diameter of the wing ring (D5), and the casing should be poured in the wall at a time;

3. The thickness of the concrete wall through the pipe should be no less than 300, otherwise the wall should be thickened on one side or on both sides, and the diameter of the thickened part should be at least D5+200;

4. The weight of the casing shall be calculated by L=300. If the wall thickness is greater than 300, it shall be calculated separately.

Innovative stainless steel waterproof casing pipe applications:：

Stainless steel waterproof casing pipe is generally suitable for structures with vibration or strict waterproof requirements where the pipe passes through the wall; If the wall through the wall is not concrete, the concrete wall should be used instead, and the flexible waterproof casing pipe should be solidified in the wall at one time; Stainless steel waterproof casing pipe applied to construction, chemical industry, steel, tap water, sewage treatment units.
