Professional Manufacturer of High-Quality Perforated Pipes
Since 1998, Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer in the wire mesh and perforated metal industry. With an annual export value of US$5–10 million and a global customer base spanning North America, South America, Europe, Southeast Asia, Africa, and Oceania, we deliver durable and precision-engineered products. Our Schedule 40 Carbon Steel Straight Seam Welded Perforated Pipe, 2-inch diameter with 0.25-inch holes, is designed to meet diverse industrial needs—offering superior strength, reliable flow performance, and long service life. Whether for filtration, drainage, or structural applications, this pipe provides a cost-effective solution backed by decades of manufacturing expertise.
Product Overview
This perforated pipe is manufactured from high-quality carbon steel, conforming to Schedule 40 wall thickness for robust pressure handling. The straight seam welded construction ensures consistent wall integrity, while the staggered 0.25-inch holes are precisely punched to provide uniform open area for optimal liquid or gas flow. Ideal for well screens, water treatment, industrial filtration, ventilation systems, and architectural projects, the pipe combines mechanical strength with efficient permeability.
Key Features & Technical Specifications
- Material: Premium carbon steel (ASTM A53 Grade B equivalent) – ensures high tensile strength and weldability.
- Schedule 40 Wall Thickness: 2-inch nominal pipe with 0.154-inch wall thickness – suitable for moderate pressure applications up to 300 psi (depending on temperature).
- Hole Configuration: 0.25-inch diameter holes, staggered pattern at 60° or 90° centers (customizable). Open area typically 23–30% for efficient flow.
- Welded Construction: Straight seam high-frequency induction welding – provides smooth internal bore and consistent strength.
- Surface Finish: Available in black (mill varnish), hot-dip galvanized, or plain oiled finish. Custom coatings (e.g., epoxy, PVC) available upon request.
- Length Options: Standard 20-foot lengths; custom lengths (up to 40 feet) can be ordered.
- End Connections: Plain ends, beveled ends, or threaded ends (NPT). Options for coupling or flanges on request.

Advantages & Customer Benefits
- Durability: Carbon steel schedule 40 pipe resists deformation under load, making it ideal for deep well screens or industrial supports.
- Efficient Flow: Staggered hole pattern maximizes open area while maintaining structural integrity – reduces pressure drop in filtration systems.
- Customizable: We offer flexible hole patterns, end finishes, and coatings to match your specific project requirements. Minimum order quantities are negotiable.
- Cost-Effective: Straight seam welded production is more economical than seamless pipe, while still providing reliable performance for most applications.
- Versatile Applications: Suitable for water well screens, drainage pipes, air intake/exhaust systems, soundproofing, agricultural irrigation, and architectural railing inserts.
- Global Shipping: We ship from Tianjin, Qingdao, Shanghai, and Foshan ports with efficient logistics to North America, Europe, Asia, and beyond.

Frequently Asked Questions
-
Q: What is the maximum working pressure for this pipe?
A: Schedule 40 carbon steel pipe typically has a working pressure of around 300 psi at ambient temperature, but the perforations reduce the pressure rating. For specific pressure requirements, please consult our engineering team. -
Q: Can the holes be custom-sized or spaced differently?
A: Yes, we offer custom hole diameters, patterns (staggered, straight rows, etc.), and center distances. Please provide your drawing or specifications for a quotation. -
Q: How is the pipe surface protected against corrosion?
A: Standard finish is black varnish (mill coating). For outdoor or corrosive environments, we recommend hot-dip galvanized or epoxy coating. Custom coatings are available on request. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ varies by size and finish. Typically, we can start from 10 pieces for standard sizes. Contact us for details. -
Q: Can you supply threaded ends or flanges?
A: Yes, we can provide NPT threaded ends, beveled ends for welding, or attach flanges per your specifications. Additional charges apply. -
Q: How long does delivery take?
A: For standard sizes and finishes, production takes 10–15 working days. Shipping time depends on destination port and mode (sea/air). -
Q: Do you provide samples?
A: Yes, samples (cut pieces) are available for quality evaluation. Please cover the shipping cost. -
Q: Is this pipe suitable for drinking water applications?
A: For potable water, we recommend using a food-grade epoxy lining or galvanized finish. Please specify your requirements so we can advise accordingly.
