About Naman Pipe and Tubes - Steel Pipes Supplier in India

India lists eight active steel products under the Naman Pipe and Tubes catalogue. The entries cover stainless‑steel sheets, duplex and super‑duplex pipe and tube forms, as well as carbon‑steel seamless and welded tubes, each identified by HS‑code families such as 7219, 7304, 7305 and 7306. The material specifications include Super Duplex UNS S32750, Duplex UNS S32205 (2205), and carbon‑steel grades S355, S235JR and API 5L X42‑X65. All items are classified under the broader categories of Steel Sheets, Steel Pipes and Steel Tubes as indicated in the supplier’s top categories.

The catalogue groups products by processing type: fabricated tubes (HS 7305.19), seamless tubes (HS 7304.19), welded tubes (HS 7306.30), square and round duplex pipes (HS 7304.49, 7304.41), and duplex or super‑duplex sheets (HS 7219.31, 7219.12). Each entry specifies the alloy composition or grade, enabling buyers to match the listed material to standard specifications used in pressure‑handling, corrosion‑resistant and structural applications.

Product Range and Specialties of Naman Pipe and Tubes

The eight listed items span three material families. Super Duplex sheets (UNS S32750) are typically supplied to petrochemical and offshore sectors for their high pitting resistance, while Duplex 2205 sheets and pipes meet ASTM A240 and API 6A requirements for moderate‑temperature, high‑strength service. Carbon‑steel seamless and welded tubes correspond to ASTM A106/A53 and API 5L specifications, covering pressure‑class X42 to X65. Industry practice distinguishes these products by dimensions, wall thickness, and pressure rating; for example, duplex pipes are often ordered in diameters from 2 in to 24 in with wall thicknesses up to 0.5 in, and sheets are supplied in 2 mm to 12 mm thicknesses. Typical quality grades include EN 10210 for welded tubes and EN 10216 for seamless tubes, which align with the material descriptions in the catalogue.

Trade and Export Information - Naman Pipe and Tubes

Export of steel tubes and sheets from India commonly targets the Middle East, Europe and Southeast Asian markets, where construction, oil‑and‑gas, and shipbuilding industries require corrosion‑resistant alloys. The HS‑code families 7219, 7304, 7305 and 7306 fall under Chapter 72 and 73, which are subject to standard customs valuation and may require a Certificate of Origin and a Material Test Certificate for customs clearance. Buyers frequently request ISO 9001 quality‑management certification and EN 10204 3.1 mill test reports to verify compliance with ASTM, API and DIN standards. Shipping is typically arranged in 20‑ft or 40‑ft containers, with steel sheets palletised and tubes crated; Incoterms such as FOB or CIF are standard for bulk steel exports.

Sourcing from Naman Pipe and Tubes - Buyer Guidance

When sourcing from Naman Pipe and Tubes, buyers should obtain the mill test certificate that lists chemical composition, tensile strength, yield strength and impact values for the specific grade (e.g., UNS S32750 or API 5L X65). Requesting an EN 10204 3.1 test report and, where applicable, a third‑party inspection report (e.g., SGS or Bureau Veritas) helps confirm that the material meets the required ASTM/AISI standards. Verify the product dimensions, tolerance limits and pressure‑rating documentation before confirming order quantities, and clarify packaging requirements such as wood‑crate versus steel‑bundle to match handling at the destination port.

What steel grades are included in the Naman Pipe and Tubes catalogue?

The catalogue lists Super Duplex UNS S32750 sheets, Duplex UNS S32205 (2205) sheets and pipes, carbon‑steel grades S235JR, S275JR, S355JR and API 5L grades X42‑X65 for seamless and welded tubes.

Which HS codes correspond to the duplex pipe products?

Duplex square pipes use HS 7306.40, duplex round pipes use HS 7304.49, and duplex bush pipes are classified under HS 7304.41.

What certifications should a buyer request for these steel products?

Buyers normally request an ISO 9001 quality‑management certificate, an EN 10204 3.1 mill test certificate, and any applicable API or ASTM conformity documents.

Are samples available for the Super Duplex sheets?

Suppliers of Super Duplex sheets typically provide a small sample cut (e.g., 100 mm × 100 mm) together with the chemical analysis report upon request.

What are typical minimum order quantities for the duplex pipes?

Industry practice for duplex pipe orders starts around 5 metric tons, depending on diameter and length, with larger shipments consolidated in standard containers.

What lead time is common for fabricated tubes?

Fabricated carbon‑steel tubes are usually produced within 4‑6 weeks after receipt of a confirmed order and required test documentation.

How are the steel sheets packaged for export?

Sheets are commonly palletised on wooden pallets, wrapped in protective film, and loaded into 20‑ft or 40‑ft containers to prevent deformation.

Which regions import these Indian steel products most frequently?

The primary import regions are the Gulf Cooperation Council countries, European Union members, and Southeast Asian nations such as Vietnam and Malaysia, where the alloys are used in petrochemical, construction and marine applications.
