Special filter pipe for 1500 meter deep water well filtration layer
Company Profile: Guangxing Wedge Wire Welding Filter Pipe and Water Well Specialized Manufacturing. Welcome to order and negotiate! 
Professional customized diameter 139.7 177.8 219 deep water well filter water dedicated filter pipe
The outer layer is wrapped with wire and the inner layer is perforated with double-layer filter pipes. This product adopts a filter pipe made of trapezoidal wire and support strip wrapped and welded with the outer layer, and the inner layer is made of stainless steel or carbon steel perforated pipes. The product has high filtration accuracy and compression resistance, and is suitable for high depth and high compression drilling projects such as deep water wells, geothermal wells, hot springs, and oil wells. Advantages and characteristics:
1. The gap between the Johnson filter pipes is a Vee shaped opening. This design ensures the smoothness of water resource filtration. 
2. The Johnson filter pipe body has high-density uniform gaps, ensuring the opening area and non blocking of the filter pipe, and avoiding the accumulation of sediment. This not only greatly improves production efficiency, but also extends the service life of the water well. 
3. The wire winding and all supporting wires are connected by electric welding, which is sturdy and durable, and has a longer working life cycle. 
4. The longitudinal arrangement of support wires and the continuity gap form of the sieve tube designed according to actual needs make the product have higher compressive performance. 
5. Johnson filter pipe specifications and connections can be manufactured according to different needs. The oil sand control screen tube is a type of sand control screen tube suitable for deep well oil and gas extraction. It has a tube wall with dense holes, an inner tube with tapered threads at both ends, and an outer protective tube with a longitudinal narrow seam. A metal screen is sandwiched between the two tubes, and the joint edge of the screen mesh protrudes from the narrow seam of the protective tube to form a screen joint and a welded fusion joint fixedly connected to the protective tube. A pipe clamp with a longitudinal long hole is installed on the outer protective tube. The petroleum sand prevention screen tube includes an inner layer tube with dense holes, a screen mesh on the tube, and a protective tube with dense holes on the screen mesh. The petroleum sand prevention screen tube is characterized by: the two ends of the inner layer tube are equipped with tapered threads, the screen mesh is divided into two layers of fine and coarse mesh, and the protective tube is equipped with longitudinal narrow gaps; Two layers of coarse and fine mesh screens wrap around the inner tube, and the joint edge protrudes from the protective tube to form a screen joint and a welded fusion joint fixedly connected to the protective tube; A pipe clamp with longitudinal long holes is set at both ends of the protective tube.
