Hot Expanded
Seamless Steel Pipe – Premium Carbon Steel Tubing for Industrial & Infrastructure Projects This high-performance hot expanded seamless
Steel Pipe is engineered for demanding applications across global industries, offering a cost-effective alternative to traditional rolled or welded tubes. Unlike conventional manufacturing methods such as cold drawing or extrusion, this advanced thermal expansion process enhances dimensional accuracy, reduces material waste, and enables the production of large-diameter, thin-walled seamless pipes that are otherwise difficult to source. Ideal for custom projects requiring non-standard specifications, it bridges critical gaps in international supply chains where off-the-shelf solutions fall short. Key Features: - Outer Diameter Range: 6" to 36" (DN15–DN900) - Wall Thickness: 4mm to 40mm (SCH10 to SCH160) - Material Grades: Low Carbon Steel, API 5L Grade B, ASTM A106, EN 10216-1, DIN 2448 - Surface Finishes: Black Painted, Anti-Rust Oil, Hot Galvanized, Cold Galvanized, 3PE Coating - Length Customization: 2 to 12 meters based on project requirements - Monthly Production Capacity: Up to 30,000 metric tons Manufactured using a controlled heating and mechanical expansion technique post-piercing, these seamless tubes ensure uniform wall thickness, minimal internal defects, and superior mechanical properties compared to standard rolled products. The process improves ductility, enhances surface integrity, and supports rapid turnaround times—making it ideal for time-sensitive infrastructure developments and industrial upgrades worldwide. With options for corrosion-resistant coatings and precise sizing, users gain flexibility without sacrificing performance. Common Applications: Used extensively in oil and gas transmission systems, steam pipelines, district heating networks, chemical processing units, and structural frameworks for buildings, bridges, and offshore platforms. These pipes excel in low-to-medium pressure fluid conveyance environments, including natural gas distribution lines, boiler feedwater systems, and petrochemical reactors. Their compatibility with various protective finishes makes them suitable for both indoor and outdoor installations under harsh conditions. Customer Feedback: Global clients consistently report exceptional reliability under operating pressures, consistent dimensional control, and excellent value for money. Procurement teams appreciate the ability to order customized sizes quickly while maintaining compliance with international standards like API, ASME, and EN. Engineers highlight improved weldability and reduced need for secondary machining due to enhanced surface quality and straightness. Frequently Asked Questions: What distinguishes hot expanded seamless steel pipe from cold rolled or welded alternatives? Unlike welded pipes, which may have seam weaknesses, hot expanded tubes offer full homogeneity and higher tensile strength. Compared to cold-rolled versions, they provide greater adaptability in diameter and wall thickness, along with better surface finish consistency due to heat treatment during expansion. Can this pipe withstand elevated temperatures? Yes, when equipped with appropriate surface treatments such as anti-rust oil, hot galvanizing, or 3PE coating, these pipes perform reliably in high-temperature environments typical of steam lines, refinery processes, and boiler systems. Is there a minimum order quantity? Orders can be tailored to individual project needs—whether small batches for pilot installations or bulk orders for large-scale infrastructure. Delivery timelines typically range from 20 days after payment confirmation or letter of credit issuance. For engineers, contractors, and procurement professionals seeking durable, scalable, and technically optimized tubular components for global industrial projects, hot expanded seamless steel pipe delivers unmatched versatility. Whether used in energy transport, civil engineering, or heavy manufacturing, it meets the highest expectations for strength, precision, and long-term service life.
