Seamless and welded pipes play a vital role in modern industries, offering unmatched strength, durability, and reliability for fluid transportation, structural applications, and high-pressure operations. At Neonox Overseas, we specialize in manufacturing and supplying a comprehensive range of seamless and welded pipes designed to meet diverse industry needs. These pipes are widely used in oil & gas, petrochemicals, power generation, pharmaceuticals, food processing, water treatment, and construction projects worldwide.
Seamless pipes are produced from solid billets and extruded into a hollow structure without any welding seam. This gives them superior strength, excellent pressure resistance, and uniform structure, making them ideal for critical applications such as boilers, heat exchangers, high-pressure pipelines, and offshore structures. They are particularly preferred where leakage, corrosion resistance, and dimensional accuracy are of utmost importance.
Welded pipes, on the other hand, are manufactured by rolling metal sheets into a cylindrical shape and welding along the seam. These pipes are cost-effective, versatile, and available in larger diameters compared to seamless pipes. Welded pipes are extensively used in low to medium-pressure applications, water pipelines, construction, structural supports, and chemical processing plants. With advanced welding technologies such as Electric Resistance Welding (ERW), High-Frequency Induction Welding (HFIW), and Submerged Arc Welding (SAW), welded pipes now deliver exceptional reliability with minimal risk of defects.
We offer both seamless and welded pipes in a variety of materials to cater to different operating conditions. Our stainless steel pipes (304, 304L, 304H, 316, 316L, 321, 347, etc.) provide excellent corrosion resistance for chemical and marine environments. Duplex and super duplex pipes (2205, 2507) offer high strength and resistance to chloride stress corrosion cracking. Alloy steel and carbon steel pipes are widely chosen for power plants, refineries, and petrochemical industries due to their heat resistance and toughness. For specialized applications, we supply nickel alloys, Inconel, Monel, Hastelloy, SMO 254, Alloy 20, titanium, and copper nickel pipes, which provide excellent performance in extreme environments including high temperature, cryogenic, and highly corrosive conditions.
Our seamless and welded pipes are available in a wide range of sizes, thicknesses, and specifications, strictly conforming to international standards such as ASTM, ASME, DIN, EN, and ISO. Customers can choose from different surface finishes such as polished, pickled, or coated depending on application requirements. With strict quality testing and precision engineering, Neonox Overseas ensures pipes that deliver long-lasting performance, leak-proof connections, and optimum efficiency in every industrial system.
Whether you require high-pressure seamless pipes for power plants, large-diameter welded pipes for construction, or special alloy pipes for aggressive chemical environments, Neonox Overseas is your trusted global supplier. With a commitment to timely delivery, competitive pricing, and customer satisfaction, we continue to serve industries across the world with high-quality seamless and welded pipes that meet every technical requirement.
