Advanced Titanium Weld Neck (WNRF) Flanges

Our ASME B16.5 Titanium Weld Neck Flanges are specifically designed for critical high-pressure and extreme temperature applications. Characterized by their long, tapered neck, these flanges provide essential reinforcement and support to the piping system. Manufactured from premium Grade 2 and Grade 5 titanium, our weld neck flanges offer an exceptional strength-to-weight ratio and unrivaled corrosion resistance in harsh chemical and offshore environments.

Why Use Our Titanium Weld Neck Flanges?

• Stress Distribution: The tapered hub design ensures even stress distribution, reducing the risk of fatigue and leakage at the joint.
• Bright Surface Finish: Each flange is CNC machined to a smooth, bright finish, ensuring precise fitment and easy welding.
• Lightweight Performance: Being approximately 45% lighter than stainless steel, these titanium flanges significantly reduce the overall weight of complex piping assemblies without sacrificing structural integrity.

Precision Forging & Testing

At Metalstitanium, every WNRF flange undergoes a rigorous forging process to refine the grain structure, followed by precision CNC machining. We strictly adhere to ASME B16.5 dimensions to guarantee interchangeability.

• Material Grades: Gr1, Gr2, Gr5, Gr7, Gr12.
• Pressure Classes: 150#, 300#, 600#, 1500#, up to 2500#.
• Quality Assurance: 100% visual inspection and dimensional checking. Material Test Certificates (MTC) to EN 10204 3.1 are provided with every order.

FAQ:

• Q: What is the main benefit of a Weld Neck Flange over a Slip-on Flange?

  • A: Weld neck flanges are superior for high-pressure and fluctuating temperature conditions due to their structural reinforcement and reduced turbulence at the pipe joint.

• Q: Do you offer Raised Face (RF) or Flat Face (FF) options?

  • A: Yes, we provide both RF and FF configurations. The Raised Face is standard for increasing the pressure-concentrating capability of the gasket.

• Q: How do you ensure the weldability of the titanium flange?

  • A: We ensure the surface is free of contamination and oxides, providing a "Bright Surface" that is ready for high-quality TIG or plasma welding.
