Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998, exporting high-quality well screen pipes to over 15 global markets. Our 2-Inch OD Galvanized Well Screen Pipe with Circular Holes, 20% Open Area, 1.5m Length is engineered to deliver efficient water extraction while maintaining structural integrity. Whether you need a reliable solution for residential wells, agricultural irrigation, or industrial dewatering, this product combines durability with optimal flow performance.
The 2-inch outer diameter (50.8 mm) fits standard well casings, and the 20% open area is carefully balanced to maximize water inflow without compromising pipe strength. Each screen is hot-dip galvanized inside and out, providing excellent corrosion resistance for long service life in harsh groundwater environments. The precisely punched circular holes ensure uniform water distribution and reduce clogging from sand or gravel.
Below we detail the key features, technical specifications, and benefits of this product.

Advantages & Customer Benefits
Enhanced Water Flow: The 20% open area allows more water to enter the well compared to standard screens with lower open area, reducing drawdown and improving pump efficiency.
Durable Corrosion Protection: Hot-dip galvanizing provides a thick zinc layer that resists rust in aggressive groundwater, extending the screen life by years.
Reduced Clogging: Circular holes with smooth edges minimize sand and gravel sticking, and the staggered pattern prevents bridging of particles.
Easy Installation: The 1.5m length is manageable for manual handling, and threaded ends allow quick connection to standard well casing joints.
Customizable Options: We can adjust hole diameter, wall thickness, and connection type to match your specific well conditions. Contact us for custom slot sizes.
Cost-Effective: Our direct-from-manufacturer pricing and 20+ years of production experience ensure competitive quality without compromising performance.

Frequently Asked Questions
Q1: What is the outer diameter of this screen pipe? Is it a true 2 inches?
A: Yes, the outer diameter is exactly 2 inches (50.8 mm). It fits standard 2-inch well casings and couplings. The tolerance is within ±0.5 mm.
Q2: Can I get a different open area percentage, such as 15% or 25%?
A: Yes, we can customize the open area. The 20% is a standard option, but we can adjust hole size and spacing to achieve other open areas. Please contact us with your requirements.
Q3: What is the wall thickness of the pipe?
A: The standard wall thickness for our 2-inch galvanized well screen is Schedule 40 (approx. 3.9 mm). Other gauges such as Schedule 80 or custom thickness are available upon request.
Q4: Are the ends threaded? How do I connect multiple sections?
A: The ends can be threaded (male/female) or left plain for slip-on coupling. Threaded connections are most common. We can also provide couplings if needed. Let us know your preference.
Q5: Is this screen suitable for sandy aquifers?
A: Yes, circular holes with 20% open area work well in sandy conditions. However, for very fine sand, we recommend a smaller hole diameter (e.g., 0.5mm slot) or a pre-packed screen. We can customize the hole size based on your sand sample analysis.
Q6: What is the maximum depth this screen can be used for?
A: The depth capability depends on the pipe wall thickness and overall well design. Schedule 40 galvanized steel screens can typically handle depths up to 200-300 meters in moderate conditions. For deeper wells, we recommend Schedule 80 or thicker walls. Contact our engineers for a specific recommendation.
Q7: How is the screen packaged for export?
A: We package screens in bundles with steel strapping, or in wooden crates for extra protection. Each bundle is labeled with size, quantity, and production date. We can also provide palletized packaging upon request.
Q8: Do you offer samples? What is the lead time?
A: Yes, we can provide samples (cost and freight to be covered by buyer). Standard production lead time is 15-25 days after order confirmation, depending on quantity. We can expedite for urgent orders.
