The primary materials used are 20# seamless steel pipe and Q235B/Q345B straight-seam welded pipe. Production complies with international standards such as GB/T (China), ASTM (USA), DIN (Germany), and JIS (Japan). Original mill material certificates and third-party quality inspection reports are available to meet import customs clearance and acceptance requirements for overseas projects.

- Outer Diameter: 42mm, 48mm, 50mm, 76mm, 89mm, 108mm; custom non-standard diameters up to 325mm are available upon request.

- Wall Thickness: 3.0mm–8.0mm; custom increased wall thickness is available for deep-buried, high-pressure, or fractured rock conditions.

- Standard Lengths: 1.5m, 3m, 4m, 6m; custom lengths can be cut according to overseas project drawings.

The pipe body features uniformly spaced "plum-blossom" shaped grout overflow/injection holes (6–10mm diameter) with adjustable spacing (150–400mm). Precision-machined external threads at the ends allow for rapid connection and extension using matching internal-thread couplings. Plastic thread protectors are fitted to prevent impact damage during transport. The entire pipe body undergoes an anti-rust blackening treatment to resist corrosion caused by humidity during ocean shipping and storage.

One end of the pipe can be machined with a pointed guide tip, allowing it to be driven directly into the ground via impact without pre-drilling, significantly boosting construction efficiency at overseas sites.

1. Threaded connection design: Offers easier assembly and disassembly compared to traditional welding; ensures a secure, leak-proof seal during grouting; and allows for repeated use.

2. Direct-from-factory mass production: Supports full-container export packaging (options include wooden crates or woven bags) and is suitable for long-distance ocean shipping.

3. Comprehensive stock availability: Standard sizes are ready to ship; custom sizes and special thread types can be manufactured based on drawings; and one-stop supply is available for matching couplers, grout plugs, and grouting accessories.

4. Export documentation support: Facilitates the handling of import/export paperwork and supports various trade terms, such as FOB and CIF.
