1. Core Commitment: Safety Begins with Every Connection
In the field of high-pressure fluid transport, the safety of ASTM A53 Grade B Threaded Pipe directly determines the lifespan of the entire project. We are not just manufacturing steel pipes; we are building a defense line. Every pipe leaving our facility must undergo the industry's most stringent physical and chemical performance inspections to ensure it remains rock-solid under complex working conditions.
2. Reject Weld Defects: Full "X-Ray Scanning" for Every Pipe
On our production lines, we perform Ultrasonic Testing (UT) on all pipes. This is a Non-Destructive Testing (NDT) technology that uses high-frequency sound waves to detect internal metal defects. Compared to cheap products that only undergo visual inspection, our testing goes deep into the weld seam to accurately identify invisible pores, cracks, or lack of fusion.
3. "Zero Leakage" Challenge: Extreme Hydrostatic Simulation
Before shipment, every single pipe must endure the Hydrostatic Test Pressure. We inject pressure far exceeding the design standards and hold it. While many low-cost suppliers take shortcuts by sampling or forging data to save costs, we insist on 100% inspection. This ensures that every Threaded and Coupled (T&C) pipe will never leak during actual operation.
- Table: Typical Hydrostatic Test Pressure Standards for ASTM A53 Grade B
| Nominal Pipe Size (NPS) | Schedule (Wall Thickness) | Outside Diameter (OD) | Hydrostatic Test Pressure |
| 1/2" | Sch 40 | 21.3 mm | 700 PSI (48.3 bar) |
| 1" | Sch 40 | 33.4 mm | 700 PSI (48.3 bar) |
| 2" | Sch 40 | 60.3 mm | 2500 PSI (172.4 bar) |
| 3" | Sch 40 | 88.9 mm | 2220 PSI (153.1 bar) |
| 4" | Sch 40 | 114.3 mm | 2210 PSI (152.4 bar) |
| 6" | Sch 40 | 168.3 mm | 1780 PSI (122.7 bar) |
The above data is based on the ASTM A53 standard, ensuring that every ASTM A53 Grade B threaded pipe meets the rated safety threshold before delivery.
4. Seamless Integration: Millimeter-Level Thread Precision Control
Threaded joints are often the weak point of a system. We strictly implement ASME B1.20.1 Standards, using high-precision ring and plug gauges for individual inspections. High-quality threading not only ensures smoothness during installation but also guarantees long-term sealing performance under the Working Pressure Rating, saving you expensive maintenance costs later.
| NPS | Threads per Inch (TPI) | Thread Pitch | Handtight Engagement (L1) | Working Pressure Rating (EST) |
| 1/2" | 14 | 1.814 mm | 8.13 mm | Up to 2000 PSI |
| 1" | 11.5 | 2.209 mm | 10.16 mm | Up to 2000 PSI |
| 2" | 11.5 | 2.209 mm | 11.07 mm | Up to 1500 PSI |
| 3" | 8 | 3.175 mm | 19.46 mm | Up to 1200 PSI |
| 4" | 8 | 3.175 mm | 21.34 mm | Up to 1000 PSI |
5. Transparent Supply Chain: An "ID Card" for Every Meter of Pipe
To prove our quality is not just talk, every batch comes with a complete Mill Test Certificate (MTC). Through the stenciling on the pipe body, you can achieve Pipe Heat Traceability, tracing directly back to the original steel furnace heat number. This level of Steel Pipe Traceability is something low-cost competitors can never provide.
6. Value Choice: Prevention is Cheaper than Costly Remediation
Choosing low-priced products might bring instant joy during procurement, but pipes lacking rigorous testing are like a ticking time bomb. Although our investment increases production costs, it safeguards you against tens of thousands of dollars in potential downtime losses and safety risks. In the industrial sector, choosing products with comprehensive testing is the real cost-control strategy.
