They are primarily used for high-pressure fluid transportation, including oil and natural gas pipelines, hydraulic systems, and industrial heat exchangers.
Our products are manufactured in accordance with API 5L, ASTM A106, ASTM A53, JIS, DIN, and BS EN10024 standards.
Yes, we offer customized OEM services including specific lengths, outer diameters, wall thicknesses, and surface treatments like black painting.
Hot-rolled pipes are generally used for larger diameters and higher volumes, while cold-drawn pipes offer tighter dimensional tolerances and a smoother surface finish.
Corrosion resistance is enhanced through professional surface treatments, such as black painting, or by incorporating small amounts of alloying elements during production.
Our standard Minimum Order Quantity (MOQ) is 5 Tons to ensure cost-effective shipping and production.
