API 5L is primarily specified for oil and gas transportation pipelines, focusing on weldability and toughness. ASTM A106 is designed for high-temperature service, commonly used in boilers and power plants.
By eliminating the longitudinal weld seam, seamless pipes remove the weakest point of the structure, significantly reducing the risk of leaks and failure under high-pressure conditions.
Yes, provided they receive appropriate surface treatments. We offer black painting and P.E coatings to enhance resistance to atmospheric and mild industrial corrosion.
Our Minimum Order Quantity (MOQ) is 5 Tons. Lead times vary based on the total volume and specific customization requirements like length or coating.
Absolutely. All our pipes are supplied with API or ASTM mill test certificates to verify chemical composition and mechanical properties.
We support standard international trade payment methods, including Telegraphic Transfer (T/T) and Letters of Credit (L/C) to ensure secure transactions.
