They are widely used in oil and natural gas pipelines, hydraulic systems, high-pressure fluid transportation, and heat exchangers due to their strength and pressure resistance.
Our products are manufactured according to API 5L, ASTM A106, ASTM A53, JIS, DIN, BS EN10024, and ANSI B36.10M standards.
Yes, we provide OEM services including customized outer diameters (12-1828mm), wall thicknesses (2-75mm), and specific surface treatments.
We use export-standard packaging and customized plastic pipe caps/end protectors to prevent moisture and physical damage during transit.
Hot-rolled pipes are generally used for larger diameters and higher thickness, while cold-drawn pipes offer higher dimensional accuracy and a smoother surface finish.
Yes, their excellent toughness and impact resistance allow them to absorb and disperse energy, reducing the risk of brittle fractures during vibrations.
