Frequently Asked Questions (FAQ)
Q: Why choose ASTM A106 over standard carbon steel pipes?
A: ASTM A106 is specifically designed for high-temperature and high-pressure service. Combined with our precision painting, it offers better durability and safety in industrial fluid transport than standard grade pipes.
Q: Do you support third-party quality inspections?
A: Yes. We have a professional QC team and fully support inspections by third-party organizations such as SGS or BV. ISO certificates are provided with every shipment.
Q: Can I get mixed sizes in one container?
A: Absolutely. Our MOQ is one 20ft container, and we accept mixed sizes and grades to help you optimize your inventory and shipping costs.
Q: Are samples available for testing?
A: Yes, we provide samples free of charge so you can verify our pipe quality and painting finish before placing a bulk order.
Q: Where is your factory located?
A: Our factory is located in Tianjin, China’s largest steel hub, providing us with a logistical advantage due to our proximity to Tianjin Port (Xingang).
