Frequently Asked Questions

Q: What is the difference between J55 and N80 grades in API 5CT?

J55 is a lower-strength grade suitable for shallow wells, while N80 offers higher yield strength for deeper wells and more aggressive pressure environments.

Q: Why should I choose BTC connections for my casing?

BTC (Buttress Thread and Coupled) connections provide significantly higher tensile strength and better sealing capabilities, making them ideal for high-tension well applications.

Q: Do these pipes comply with international ISO standards?

Yes, our casing and tubing pipes are manufactured in accordance with API SPEC 5CT, API SPEC 5B, and ISO11960 standards.

Q: Can you provide third-party inspection reports?

Absolutely. We welcome and accept third-party inspections to ensure the quality and specifications meet your exact project requirements.

Q: What is the typical delivery time for a full container load (FCL)?

The standard delivery time is 7-10 days for one FCL, though this may vary depending on specific custom requirements and total order volume.

Q: Are custom lengths available for these steel pipes?

Yes, while we offer standard R1, R2, and R3 lengths, we can manufacture pipes to any specific length requested by the customer.
