Fabricated Tubes
Fabricated tubes from Naman Pipe and Tubes are large-diameter, welded steel tubes manufactured from carbon steel grades S355 and API 5L Grade B through X65 for structural foundation applications. These tubes feature beveled ends to enable field welding and are produced to meet international engineering standards for offshore and onshore piling. Wall thickness ranges from 12 mm to 50 mm, with outer diameters from 300 mm to 1500 mm, based on project-specific fabrication requirements.
The material composition follows standard ferritic-austenitic duplex structures, with chromium and molybdenum content enhancing corrosion resistance in marine environments. These tubes are not seamless but are formed from plate material via submerged arc welding, ensuring consistent weld integrity under high-load conditions. Typical applications include offshore wind turbine foundations, bridge piers, and seawater intake systems, where resistance to chloride-induced stress corrosion is critical.
Buyers in the Middle East, Southeast Asia, and Europe use these tubes for civil and energy infrastructure projects. Trade terms are typically FOB Mumbai or CIF Rotterdam, with payment via irrevocable L/C. Lead time for standard sizes is 25 - 35 days after order confirmation. Packaging includes steel banding, end caps, and anti-corrosion coating on exterior surfaces. Documentation includes mill test reports and ultrasonic inspection certificates for weld zones.

Sourcing Fabricated Tubes from Naman Pipe and Tubes - India Import Guide
Verify material grade and mechanical properties with a certified mill test report before ordering. Confirm that the tubes meet API 5L or ASTM A252 requirements with actual test data for yield strength, tensile strength, and elongation. Do not accept generic compliance statements without documented proof from the supplier’s lab.
Confirm Incoterms as FOB Mumbai or CIF destination port. Lead time for standard sizes is 25 - 35 days. Payment is typically via irrevocable letter of credit. Packaging includes steel banding, end caps, and exterior anti-corrosion primer. For ocean freight, request moisture-proof wrapping if shipment exceeds 30 days.
Conduct a pre-shipment inspection for weld seam quality using ultrasonic testing. Measure ovality and bevel angle with calibrated tools. Check for surface cracks, dents, or coating defects. Retain a sample of the material for future reference. Request all inspection reports and material certifications in English with lab seals. Retain documentation for customs and compliance audits.
