About Beijing Metleader Pipeline Technology Inc. - Steel Pipes Supplier in China

Beijing Metleader Pipeline Technology Inc. is based in Beijing, China, and lists 58 distinct pipeline‑related products in its catalogue. The active product count spans steel pipe, flange and stainless‑steel fitting families, each classified under HS chapters 7304, 7306 and 7307. The catalogue includes seamless and welded line pipes that comply with API 5L grades B, X42‑X70, as well as specialized grades such as X52NS and NACE MR0175. Several entries cite HS codes 7304.11, 7304.19, 7304.29, 7304.49, 7306.10, 7306.30, 7306.39, 7306.11, 7307.19, 7307.23, 7307.91, 7307.93 and 7307.99. Materials range from carbon steel (including Q235, Q345, S355) to alloy steel and stainless steel 304/316.

The product set covers line pipe for oil and gas transport, gas‑pipeline carbon steel pipe, high‑strength API 5L pipe, galvanized carbon steel pipe, large‑diameter pipe and a suite of fittings such as industrial flanges, elbows, tees and low‑temperature alloy pipe. Coated variants include 3LPE/3PE and hot‑dip zinc finishes (60‑600 g/m²). Typical API 5L specifications range from DN 50 to DN 1200 with pressure classes 5‑16 MPa, although exact dimensions are not listed. Flange entries reference ASTM A105 carbon steel and stainless steel 304/316, while pipe‑fitting entries reference ASTM A234 WPB. All items are grouped under the three top categories reported in the source data.

Product Range and Specialties of Beijing Metleader Pipeline Technology Inc.

The catalogue lists a broad spectrum of carbon‑steel line pipe, including seamless API 5L grades B to X70, PSL2‑qualified grades, and NACE MR0175‑approved X52NS for sour service. In the global market, API 5L pipe is typically supplied in grades B, X42, X52, X60 and X70, meeting ASTM A53, A106 and API 5L standards, with tolerances on wall thickness and dimensional accuracy defined in ISO 3183. Flanges are offered in ASTM A105 carbon steel and stainless‑steel 304/316, matching the pressure classes and dimensions of the ASME B16.5 family, while fittings such as elbows, tees and long‑radius elbows follow ASTM A234 WPB specifications. Galvanized pipe variants are hot‑dip coated with zinc thickness between 60 g/m² and 600 g/m², a common range for corrosion protection in water‑distribution and infrastructure projects. The product portfolio also includes low‑temperature alloy pipe (9 % Ni, ASTM A333 Grade 6) used for cryogenic applications, which typically requires impact testing at - 50 °C or lower.

Trade and Export Information - Beijing Metleader Pipeline Technology Inc.

China is a leading exporter of API 5L pipe and related fittings, with the majority of shipments destined for the Middle East (Saudi Arabia, United Arab Emirates), Southeast Asia (Vietnam, Thailand, Indonesia), Europe (Germany, United Kingdom) and Africa (Nigeria, South Africa). HS chapter 73 codes - 7304 for seamless and welded pipe, 7306 for coated pipe, and 7307 for flanges and fittings - are routinely inspected under the Chinese customs export inspection system and may be subject to third‑party certification such as API product certification, ISO 9001 quality‑management and NACE MR0175 compliance for sour‑service pipe. Importers often require CE marking or equivalent conformity assessment when the goods are destined for the European Union, and they may request phytosanitary or material‑safety data sheets for stainless‑steel products. Standard Incoterms used for these bulk steel goods are CIF or FOB, with typical containerisation in 20‑ft or 40‑ft containers, or in open‑top containers for long‑diameter pipe. Packaging generally involves wood palletisation or steel strapping, with moisture‑resistant covers for coated pipe to preserve surface finish during sea transit.

Sourcing from Beijing Metleader Pipeline Technology Inc. - Buyer Guidance

When sourcing from this supplier, buyers should request mill test certificates (MTC) that verify chemical composition, mechanical properties and heat‑treatment records for each API 5L grade. For coated pipe, a coating certificate indicating zinc weight (g/m²) or 3LPE/3PE layer thickness is essential, together with a third‑party inspection report such as SGS or Bureau Veritas. Buyers are advised to confirm that the flanges and fittings meet the relevant ASME B16.5 dimensions and that any stainless‑steel items carry a corrosion‑resistance test report (e.g., pitting resistance equivalent number, PREN). Typical minimum order quantities for bulk pipe range from 5 tons to 15 tons depending on diameter, and lead times are commonly 30‑45 days after receipt of a confirmed purchase order and required documentation. Verify that the supplier can provide ISO 9001 or API product certification copies before finalising contracts, as these are standard assurances for international pipeline projects.

What HS codes apply to the line pipe products listed by the supplier?

Line pipe entries are classified under HS 7304.19 for seamless API 5L pipe, 7304.11 for certain carbon‑steel pipe, and 7306.10 for 3LPE/3LPE‑coated pipe. The exact code depends on the pipe’s manufacturing process and coating status.

Which international standards govern the API 5L pipe grades offered?

The pipe grades follow API 5L (PSL 1 and PSL 2) and are cross‑referenced to ASTM A53, A106 and ISO 3183. Grades B, X42, X52, X60, X65 and X70 are the most common specifications.

Are there specific certifications buyers should request for sour‑service pipe?

For sour‑service applications, buyers should request NACE MR0175 compliance documentation and a mill test certificate confirming the X52NS or equivalent grade. Third‑party NACE certification is a typical requirement.

What typical packaging and container sizes are used for the steel pipe shipments?

Bulk pipe is usually bundled on wooden pallets or steel straps and loaded into 20‑ft or 40‑ft containers, or into open‑top containers for diameters exceeding 508 mm. Coated pipe is wrapped in moisture‑resistant film to protect the coating.

What documentation is standard for the flange and fitting products?

Flange and fitting shipments are accompanied by mill test certificates, ASTM A105 or A234 compliance certificates, and, when required, a CE‑type conformity declaration for EU destinations.

What are common minimum order quantities and lead times for these products?

Typical MOQ ranges from 5 tons for standard pipe to 10 tons for large‑diameter or coated pipe. Lead times are generally 30‑45 days after order confirmation and receipt of required test reports.

Which regions most frequently import Chinese API 5L pipe and related fittings?

The primary importing regions are the Middle East (e.g., Saudi Arabia, UAE), Southeast Asia (Vietnam, Thailand), Europe (Germany, UK) and Africa (Nigeria, South Africa), where the goods are used in oil‑&‑gas pipelines, water‑distribution networks and infrastructure projects.
