Flanges
The product is industrial pipe flanges manufactured by Beijing Metleader Pipeline Technology Inc., offered in stainless steel grades 304/304L and 316/316L as well as carbon steel A105. They conform to ASME, ANSI, DIN, JIS and GOST standards and are supplied in weld‑neck, slip‑on, blind, thread, socket and lap‑joint configurations. Size range spans from ½ inch to 203 inch nominal diameter, covering pressure classes from Class 75 up to Class 2500. The catalogue notes export packaging with rust‑prevention coating for safe global transit.
Typical industry practice for these classes uses a bolt circle diameter that scales proportionally with nominal size, often ranging from 100 mm for ½‑inch flanges to 2000 mm for 203‑inch units; tolerances on bore diameter are usually ±0.5 % of the nominal size. Standard material grades such as 304L stainless steel provide corrosion resistance in water‑treatment plants, while A105 carbon steel is common in petrochemical pipelines where cost is a factor. The flanges are supplied with a standard marking of pressure class, nominal size and material on each piece, facilitating quick identification during installation.
These flanges are widely used by contractors in offshore and onshore oil‑gas projects, water‑treatment facilities and chemical process plants that require reliable high‑pressure connections. Buyers typically request certification of compliance with the listed standards and may ask for custom machining of the bolt holes or hub dimensions. Trade terms, minimum order quantities and lead times are not listed; prospective importers should confirm them directly with the supplier and negotiate Incoterms and payment conditions before placing an order.

Sourcing Flanges from Beijing Metleader Pipeline Technology Inc. - China Import Guide
Before placing an order, importers should verify the exact material grade, applicable standards and any third‑party certifications that the supplier can provide. Confirm the minimum order quantity, any required custom drawings and the method of marking on the flange to avoid mismatches during installation.
Logistics for Chinese‑origin flanges usually involve sea freight from the port of Tianjin or Shanghai. Buyers need to agree on Incoterms such as FOB, CIF or DAP, and clarify payment terms - typically a deposit against pro‑forma invoice followed by balance on sight‑document. Expected lead times can vary from four to eight weeks depending on the size, pressure class and any custom work, so early confirmation is advisable.
Quality assurance commonly includes dimensional checks, hydrostatic pressure testing and visual inspection for surface defects. Importers are encouraged to arrange a pre‑shipment inspection by a recognised third‑party agency and request test certificates that reference the relevant ASME, ANSI or DIN standard. Proper documentation, including material test reports and packing lists, should be obtained before cargo release.
