Shandong Ruli Steel Pipe Co., Ltd. is a specialized steel pipe manufacturer focusing on the production of bridge-type filter pipes, spiral filter pipes, galvanized filter pipes, pit foundation drainage pipes, well casing pipes, and round hole filter pipes. It integrates production, research and development, design, development, and sales, boasting nearly two decades of production history. The bridge-type and Johnson filter pipes are exported to multiple countries and regions including Russia, Canada, Germany, Morocco, and are highly regarded in the domestic and international filter pipe industry.

Our factory utilizes fully automated filter pipe production equipment, incorporating German technology, boasting robust technical capabilities. We have innovated advanced production processes and implemented comprehensive testing methods. We have now developed and produced over sixty types of filter pipe products, including bridge-type filter pipes, all reaching the advanced national level. Particularly in recent years, our filter pipes are designed reasonably, aesthetically pleasing, and of reliable quality, suitable for construction and construction in industries such as hydrogeology, coalfield geology, chemical geology, metallurgical geology, ground temperature air conditioning, foundation water reduction, water source development, and urban water supply. We welcome friends from all walks of life to visit our factory for guidance and discuss orders.

Bridged water filters offer the following advantages compared to other types of water filters:

1. The unique structure of the bridge-shaped orifice makes it less prone to blockage by gravel. According to tests by Germany's Nord Company, the porosity of traditional water filters is reduced by 40% when filled with gravel, whereas the bridge-type water filter only sees a 10% decrease. Therefore, the bridge-type filter has a higher water permeability. After well cleaning and sand removal, a clean, sand-free water source can be obtained.

2. The special hole shape structure of the water filter enhances its mechanical strength, resulting in high mechanical integrity.

3. The coating with various anti-corrosion layers, tailored to user requirements, can extend the lifespan of the well.

4. The bridge-type water filter system is made by punching steel plates and rolling them, resulting in a lightweight and cost-effective design.

5. Offers various connection methods, thus facilitating downstream operations.

6. We can adjust the gap of the bridge opening according to customer requirements, ensuring a satisfactory porosity of the bridge opening for the user.

7. Offer bridge water filters of any diameter to meet customer requirements, providing convenience for users.
