Perforated Pipe

Perforated pipe is a type of pipe that has undergone deep processing, typically based on straight seam welded pipes, spiral seam welded pipes, or seamless pipes, and through the stamping process to punch out circular or strip holes. This special structure makes it difficult for sand and gravel to block the holes, and it has high mechanical strength and water passing capacity. Perforated pipes are widely used in various engineering fields, especially in foundation pit dewatering, subway dewatering wells, bedrock well filtration, geothermal wells, water source air conditioning wells and other projects where they perform excellently. Its high mechanical strength and water passing capacity enable it to effectively filter impurities in these projects, ensuring the smooth progress of the project.

• Features

• Materials: Common options include PVC (durable, corrosion-resistant), corrugated HDPE (flexible, ideal for uneven terrain), and metal (less common due to corrosion risks).

• Perforation Types:

  • Round Holes: Allow higher water flow but may require filtration to prevent clogs.

  • Slotted Openings: Reduce debris entry; often placed on the bottom half of the pipe to optimize drainage and minimize sediment intake.

    
    

    Applications

    1. French Drains: Redirect groundwater away from foundations.

    2. Septic Systems/Leach Fields: Distribute wastewater into the soil.

    3. Agricultural Drainage: Prevent soil waterlogging in fields.

    4. Retaining Walls: Relieve hydrostatic pressure.

    5. Roadside Drainage: Manage stormwater runoff.
