Seamless Carbon Steel Square Tube & Pipe
Description
Discover premium carbon steel pipes engineered for durability, performance, and versatility across global industries. Manufactured in Shandong, China, these tubes are produced using advanced hot-rolled, cold-rolled, and ERW (Electric Resistance Welded) techniques to meet international standards such as ASTM A53, ASTM A106, API 5L, JIS, and GB. With a wide range of outer diameters from 15mm to 1200mm and wall thicknesses including SCH10 to XXS, they offer precise dimensional control and structural reliability for demanding environments.
Key features include consistent mechanical properties, corrosion-resistant surface treatments like oil coating or galvanization, and customizable end finishes—plain, beveled, grooved, or threaded—ensuring compatibility with various piping systems. Each pipe is marked clearly for easy identification and protected with plastic caps to prevent damage during transit. The production process follows strict quality protocols, with third-party inspections available under ISO9001, SGS, BV, and CCIC certifications.
These carbon steel tubes are ideal for high-pressure applications such as fluid transport, boiler systems, hydraulic lines, oil and gas drilling, chemical processing, food-grade pipelines, construction frameworks, and mining infrastructure. Whether you require seamless pipes for elevated temperature conditions or welded options for cost-effective bulk projects, our product line delivers optimal strength-to-weight ratios and long-term service life. Available in standard lengths of 1m, 4m, 6m, 8m, and 12m—or custom sizes per client specifications—the flexibility supports diverse engineering needs.
Users worldwide praise the uniformity in dimensions, robust weld integrity, and resistance to wear under continuous operational stress. Many industrial buyers highlight the ease of installation and reduced maintenance costs when compared to alternative materials. The packaging system—a three-layer protective structure involving craft paper, moisture barrier film, and galvanized steel casing—ensures safe delivery even in harsh shipping conditions.
Common inquiries often focus on material grades like A53 Gr.B, A36, Q235, or API 5L X65/X70; all are available in both black painted and oil-coated variants. For users concerned about compliance, note that each batch undergoes rigorous chemical composition testing and tensile strength verification per ASTM and EN standards. Delivery typically occurs within 8–14 days post-order confirmation, making it suitable for time-sensitive procurement cycles.
