Inconel 625 Weld Neck Flange Delivered to UAE Customer
Haihao Group has successfully completed the delivery of a high-performance weld neck flange to a customer in the United Arab Emirates. The product was manufactured using nickel-based alloy Inconel 625 (ASTM B564 UNS N06625) and designed to meet demanding service conditions in oil & gas and petrochemical applications.
Product Details at a Glance
The supplied flange specifications are as follows:
- Product Type: Weld Neck (WN) Flange
- Nominal Size: 1-1/2 inch
- Facing Type: RTJ (Ring Type Joint)
- Material: ASTM B564 UNS N06625 (Inconel 625)
- Pressure Rating: Class 300
- Pipe Schedule: SCH 80
The 1-1/2 inch RTJ weld neck flange was precisely machined to ensure full compatibility with high-pressure piping systems and secure metal-to-metal sealing performance.
Why Choose Inconel 625 (UNS N06625)?
Inconel 625 is widely specified for critical piping components due to its outstanding properties:
- Exceptional resistance to corrosion and oxidation
- Excellent performance in high-temperature and high-pressure environments
- Strong resistance to pitting, crevice corrosion, and stress corrosion cracking
- High strength without the need for heat treatment
These advantages make ASTM B564 UNS N06625 weld neck flanges ideal for offshore platforms, refineries, and chemical processing facilities in the UAE.
RTJ Weld Neck Flanges for High-Integrity Piping
The RTJ WN flange Class 300 design combines a tapered hub with a ring-type joint groove, offering:
- Smooth stress transition between flange and pipe
- Superior sealing under high pressure
- Reduced risk of leakage in critical services
This makes Inconel 625 RTJ flanges for UAE oil and gas projects a preferred choice for safety-critical systems.
