1. Direct from the Source: ASTM A252 Grade 3 Steel Pipe Manufacturer
As a dedicated ASTM A252 Grade 3 Steel Pipe Manufacturer, we understand that every foundation project has a unique blueprint. Our production line is optimized to meet the most stringent SSAW Piling Pipe Dimensions, offering an expansive range of diameters from 219mm up to 3200mm. By controlling the manufacturing process in-house, we ensure that every millimeter of the pipe aligns with international quality benchmarks.
2. Mastering Large Diameter Piling Pipe Requirements
For heavy-duty infrastructure like bridges and high-rises, Large Diameter Piling Pipe is essential for distributing massive vertical loads. Our SSAW (Spiral Submerged Arc Welded) technology allows us to produce these giant sections with exceptional roundness and straightness. Whether you need a 1-meter or a 3-meter diameter pipe, our Grade 3 material maintains its structural integrity across the entire surface.
3. Custom Wall Thickness Steel Pipe for Specialized Loads
Standard sizes don't always fit specific soil pressures. That’s why we offer Custom Wall Thickness Steel Pipe options ranging from 5mm up to 30mm. This flexibility allows engineers to optimize the weight of the pile without sacrificing safety. By choosing the exact thickness needed, projects can achieve a better balance between material costs and structural performance.
Table 1: Standard Dimensional Range for SSAW Piling Pipes
| Parameter | Range (Metric) | Range (Imperial) |
| Outside Diameter (OD) | 219 mm – 3200 mm | 8.6 in – 126 in |
| Wall Thickness (WT) | 5.0 mm – 30 mm | 0.197 in – 1.18 in |
| Single Pipe Length | 6.0 m – 50.0 m | 20 ft – 164 ft |
| End Preparation | Square Cut or Beveled | 30° - 35° Bevel |
4. Tight Steel Pipe Dimensional Tolerances for Perfect Alignment
In the field, splicing pipes is a common task. Our commitment to strict Steel Pipe Dimensional Tolerances means that the outside diameter and out-of-roundness are kept within minimal limits. This precision ensures that when you receive our Beveled End Steel Pipe, the ends match perfectly for on-site welding, significantly reducing the time and labor required for field splicing.
Table 2: ASTM A252 Grade 3 Dimensional Tolerances
| Feature | ASTM A252 Standard Requirement | Our Factory Precision |
| Outside Diameter | ±1% | ±0.75% |
| Wall Thickness | -12.5% | ±10% |
| Weight per Foot | +15%/ - 5% | ±5% |
| Straightness | ≤ 0.2% of total length | < 0.15% of total length |
5. Reach New Depths with Extra Long SSAW Pipe
Deep foundation projects often require driving piles into bedrock situated dozens of meters underground. We provide Extra Long SSAW Pipe in single lengths of up to 50 meters, or spliced sections to meet your specific depth. This reduces the number of on-site welds required, minimizing potential weak points and ensuring a more continuous, high-strength steel column.
6. Versatility Across Standards: API 5L Grade B to ASTM A252 G3
Sometimes projects require high-performance piping that can bridge multiple certifications. We can manufacture pipes that satisfy both API 5L Grade B to ASTM A252 G3 requirements, providing the high-pressure resistance of line pipe with the structural toughness of piling pipe. This versatility makes our Standard Weight Piling Pipe the go-to choice for diverse engineering challenges.
Precision on paper, speed on-site. Having the right specifications is only the first step; how these dimensions translate into a smooth installation process is what keeps your project on schedule. From perfect alignment to rapid welding, discover how our precision-engineered pipes simplify your field operations. [Learn more about our ASTM A252 Piling Installation Guide & Best Practices.]
