Shipment of 30″ Class 600 ASTM A694 F65 WN Flange RF ASME B16.47A to UAE Client
Haihao Group has finished packing and arranged shipment of large size WN flange RF for our valued client based in the UAE. This batch of ASME B16.47A flange is built for demanding onshore pipeline projects where low-temperature toughness and sour service compliance are non-negotiable.
The supplied WN flange RF is sized 30 inch, Class 600, with a wall thickness of 23.83 mm. It is forged from ASTM A694 F65, a carbon steel grade widely selected for high-strength line pipe connections. Every ASME B16.47A flange goes through full heat treatment to stabilise mechanical properties and meet strict project acceptance criteria.
ASTM A694 F65 WN flange RF ASME B16.47A, 30 inch 600#, black painted, NACE compliant for UAE pipeline
One key requirement for this order is NACE compliance. The carbon equivalent value is controlled below 0.42 to reduce cracking risk during welding and operation. Impact test validation at -29 ℃ delivers minimum 33J absorbed energy, confirming the ASME B16.47A flange can withstand cold operating conditions without brittle failure. Non-destructive testing including UT and PT is performed on each flange to reveal internal and surface defects before delivery.
For surface protection, the ASTM A694 F65 flange is coated with black paint. This finish provides basic protection against scratching and corrosion during sea freight and storage in the Gulf region’s humid, salty atmosphere. We keep full traceability records, including heat treatment reports, impact test certificates and NDT logs, ready for the client’s third-party inspection.
Our team regularly handles large diameter forged flange orders for UAE EPC contractors. We understand that sourcing a reliable ASME B16.47A flange means more than matching dimensions. It means tight CE control, verified low-temperature impact performance and complete documentation that aligns with NACE project specifications.
