Frequently Asked Questions (FAQ)
-
Q: What is the difference between ASTM A53 Grade A and Grade B?
A: Grade B has higher tensile and yield strength (60,000 psi / 35,000 psi) compared to Grade A, making it more suitable for pressure applications. Grade B is the most commonly specified grade for seamless pipes. -
Q: Can this pipe be used for high-temperature applications?
A: ASTM A53 is typically used for moderate temperature ranges (up to about 400°F / 204°C). For higher temperatures, consider ASTM A106 or other alloy grades. Always consult your design engineer. -
Q: Is the pipe available in galvanized finish?
A: Yes, we can supply galvanized (hot-dip) coating upon request. Please specify your requirements when placing an order. -
Q: What is the standard packaging for export?
A: Pipes are bundled with steel straps, wrapped in waterproof material, or packed in seaworthy wooden crates as per your instructions. We can also provide custom packaging for fragile or special coatings. -
Q: Do you provide third-party inspection certificates?
A: Absolutely. We can arrange inspection by SGS, BV, or other recognized agencies at your cost. Mill test certificates are included with every shipment. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 10 tons for standard sizes. For smaller quantities or sample orders, please contact our sales team to discuss feasibility. -
Q: How long does delivery take?
A: For standard 20ft Schedule 40 pipes, delivery usually takes 15–25 days after order confirmation, depending on quantity and destination. Custom sizes may require longer lead time. -
