Your most trusted one-stop Pipe Flange manufacturer
Product Categories
BAFAW manufactures pipe flanges for high-pressure pipeline connections in oil, gas, and industrial systems. Each flange is produced from ASTM A105 / A182 / A350 materials, machined according to ASME B16.5 and B16.47 standards, and inspected for bolt-hole alignment, flatness, and sealing-face accuracy to ensure leak-free installation.
Supports Third-Party Inspection (RT, UT, PT, MT)
Products Tested Under ASME B16.5 / B16.47 / MSS-SP-44 / ASTM A105 Standards

FAQ About Pipe Flange
BAFAW manufactures flanges according to ASME B16.5, ASME B16.47 (Series A & B), DIN, EN 1092-1, and JIS B2220 standards.
Each flange is fully compatible with global pipeline systems, ensuring interchangeability and precise bolt alignment.
Our flanges are available in Class 150, 300, 600, 900, 1500, and 2500, tested under ASME B16.5 pressure requirements.
Each unit is hydro-tested at 1.5× the rated pressure to guarantee sealing reliability.
We supply flanges in ASTM A105 (carbon steel), A182 F304/F316 (stainless steel), and A350 LF2 (low-temperature steel).
All materials include EN 10204 3.1 certificates with chemical composition, mechanical properties, and heat number traceability.
We produce Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ) sealing surfaces.
Face roughness is controlled within Ra 3.2–6.3 μm, ensuring tight, leak-free gasket contact.
All flanges are CNC machined with bolt-hole tolerance ≤ ±0.2 mm and flatness ≤ 0.3 mm for Class 150–600 sizes.
Every batch is inspected with calibrated gauges to ensure perfect field alignment.
Yes. Standard finishes include black oxide, zinc plating, and anti-rust oil coating.
For marine and offshore projects, epoxy or hot-dip galvanizing (≥70 μm) is available, tested for ≥480 hours salt spray resistance.
Absolutely. We support SGS, BV, TUV, and LR inspections.
Each shipment includes MTC (EN 10204 3.1), and upon request, NDT reports (UT, RT, PT, MT) according to ASME Section V.
Standard flanges (≤DN600) ship within 7–10 days; large-size flanges (DN700–DN2000) within 25–30 days.
MOQ starts at 50 pcs per size, with custom production available for project-based quantities.
