Long Weld-Neck Flanges
The Long Weld-Neck Flange (LWN) is a specialised flange with an extended neck that improves stress distribution in high-pressure pipelines. Highborn Flanges & Fittings India Pvt Ltd offers LWN flanges in stainless-steel grades 304/304L and 316/316L as well as carbon-steel grades A105 and A350. Sizes run from ½ inch to 60 inch with pressure classes from 150 up to 2500, complying with ANSI/ASME, DIN and EN standards. Each unit is packed in wooden crates or pallets with rust inhibitors to protect the surface during export.
Typical industry practice uses a neck length of 1.5 - 2 times the flange thickness to maintain rigidity under fluctuating temperatures. Standard tolerances on the flange diameter are ±0.5 mm and the surface finish is usually 63 Ra, which matches the requirements of petrochemical plants. The flanges are supplied in both standard type and heavy-gun type variants, allowing selection based on load and temperature conditions.
Primary users include oil-field operators, refinery engineers and chemical-process plant designers who need reliable nozzle connections. Buyers typically request certification to the relevant ASME code and may ask for test reports such as hydro-static pressure tests. Trade terms are negotiated per order; Highborn can ship on CIF or FOB basis once the buyer confirms quantity, packaging and incoterm preferences. Because the supplier’s response rate is currently zero, the importer should verify the current contact details and request a formal quotation before placing an order.

Sourcing Long Weld-Neck Flanges from Highborn Flanges & Fittings India Pvt Ltd - India Import Guide
Before placing an order, importers should request the material test certificates that confirm the stainless‑steel or carbon‑steel grade and verify that the flange dimensions match the engineering drawing. It is also advisable to obtain the latest ASME, DIN or EN compliance documents and to confirm the supplier’s active communication channels given the recorded zero response rate.
Logistics for LWN flanges typically involve sea freight with lead times that depend on order size and vessel schedules. Buyers should agree on Incoterms such as CIF or FOB and clarify payment terms, often a 30‑day letter of credit or advance payment, before the shipment is booked. Confirming the exact quantity, packaging method and any special handling requirements will help avoid delays.
Quality assurance for these flanges includes hydro‑static pressure testing at the rated class and visual inspection for surface defects. Importers may arrange third‑party inspection at the factory or at the port of loading. Ensure that the supplier can provide test reports, material certificates and, if required, non‑destructive testing records as part of the import documentation.
