- Standard 1.5m Length – Convenient for handling, transportation, and installation. Custom lengths are available upon request to match your well screen string design.
- Mill Test Report Included – Each batch is tested for chemical composition and mechanical properties, providing full traceability from raw material to finished product.

Detailed Product Advantages
- High Flow Efficiency: The continuous slot design (either wire-wrapped or slotted pipe) minimizes friction loss and allows maximum water passage. This reduces pump energy consumption and extends equipment life.
- Anti-Clogging Performance: The V-shaped slot profile (if applicable) creates a self-cleaning effect, preventing sand particles from becoming wedged inside the slot. This is especially beneficial in fine sand formations.
- Durability & Longevity: 304 stainless steel withstands mechanical stress during installation and operation. Our screens are used in wells with depths exceeding 300 meters and have a service life of 10+ years under normal conditions.
- Easy Installation: Each screen section comes with compatible connections. We can supply plain ends, male/female threads, or other joints as requested. The 1.5m length is lightweight and easy to handle with standard rigging equipment.
- Quality Assurance: Every screen is inspected for slot size, roundness, straightness, and surface finish. Our in-house testing includes dimensional checks and hydraulic testing to ensure consistent quality.

Frequently Asked Questions
-
Q: What is the difference between 304 and 316 stainless steel well screens?
A: 304 offers excellent corrosion resistance in fresh water and mild environments, while 316 provides better resistance in saltwater or highly corrosive conditions. Our 0.4mm slot screen is available in 304 as standard; 316 can be ordered on request. -
Q: Can I get a custom length other than 1.5m?
A: Yes, we can customize the length to any dimension you need, such as 1.0m, 2.0m, or 3.0m. Minimum order quantity may apply for custom lengths; please contact our sales team. -
Q: Does the screen come with a threaded connection already attached?
A: We can supply plain ends, male/female threaded ends, or welded couplings according to your specifications. The standard connection type is NPT threaded. Please specify your need when ordering. -
Q: What is the maximum well depth this screen can handle?
A: The 304 stainless steel screen is suitable for depths up to 300–400 meters depending on diameter and wall thickness. For deeper wells, we recommend a thicker wall or a stronger material like 316L or duplex stainless steel. -
Q: How is the Mill Test Report provided?
A: The MTR is issued by our factory for each heat number of the raw material. It includes chemical composition (C, Mn, Si, S, P, Cr, Ni) and mechanical properties (tensile strength, yield strength, elongation). We send a digital copy with the shipment; a hard copy can be included upon request. -
Q: Can you supply the screen with a protective coating or wrap?
A: Yes, we can provide additional PVC coating or a protective wrap for transportation. However, for most well applications, the bare stainless steel surface is sufficient. -
Q: What is the typical lead time for this product?
A: For standard sizes (1.5m length, 0.4mm slot, 304 SS), lead time is 10–15 working days. Custom orders may take 20–30 days depending on quantity and complexity. -
Q: Do you offer samples before bulk order?
A: Yes, we can provide a sample of 1 meter length for evaluation. The sample cost is US$50–100 (including shipping), which will be deducted from the first full order.
