Welding neck flanges
Xiamen Bluesea Piping Systems Co., Ltd. supplies welding neck flanges forged from stainless steel 304/304L, carbon steel A105 and alloy steel F11/F22. The flanges feature a long tapered hub and are offered with Raised Face, Full Face or Ring Tongue Joint faces. Each unit conforms to ASME B16.5 and ANSI standards for flange dimensions and pressure classes. The catalogue lists a minimum order of ten pieces per size.
In the industry, welding neck flanges typically cover diameters from DN 50 to DN 600 and pressure ratings from PN 150 to PN 2500, although exact limits depend on the chosen material. Thickness tolerances are usually held within ±0.5 mm to ensure sealing integrity. The raised‑face and full‑face options suit gasket classes up to 150 bar, while the ring‑tongue joint version is preferred for high‑temperature service. These typical dimensions align with the requirements of high‑pressure pipelines in petrochemical and power sectors.
Major users include oil and gas producers, petrochemical plants and electricity generators that need leak‑tight connections in critical pipelines. The supplier states a production capacity of 200 ton per month and ships the flanges in wooden crates or pallets for sea freight. Payment is normally by Letter of Credit and the stated delivery window is fifteen days from order confirmation.

Sourcing Welding neck flanges from Xiamen Bluesea Piping Systems Co., Ltd. - China Import Guide
Before placing an order with Xiamen Bluesea Piping Systems, importers should verify that the material grade and flange face type match the engineering specifications of their project. Request the supplier’s mill test report (MTR) and a certificate of compliance confirming adherence to ASME B16.5. Because the platform data shows a zero percent response rate, it is prudent to obtain a direct telephone or video confirmation of the contact person’s availability. Confirm the production capacity claim of 200 ton per month if large volumes are planned.
Logistics for the flanges are handled via sea freight, with the supplier indicating a fifteen‑day delivery window from order confirmation. The listed packing in wooden crates or pallets should be inspected for integrity upon arrival, and buyers may request pallet‑level shrink‑wrap for added protection. Payment is normally arranged through a Letter of Credit, which balances risk between buyer and supplier. Importers should also clarify the Incoterm - most shipments are quoted FOB Xiamen, but CIF can be negotiated if desired.
Quality assurance relies on the supplier’s internal forging controls, but buyers are advised to arrange third‑party inspection before shipment, focusing on dimensions, face finish and material composition. Request a final inspection report that
