Nickel Alloy Weld Neck Flange ASME B16.5 Forged Class150-2500 RF/RTJ
Product Description
ASME B16.5 Forged Nickel Alloy Flange Class150-2500 Weld Neck RF/RTJ
Product Description
These nickel alloy steel flanges are manufactured in strict compliance with the ASME B16.5 standard, adopting high-quality nickel alloy material and precision forging process. Available in pressure classes Class150 to Class2500, they include Weld Neck (WN) type with two face options: Raised Face (RF) and Ring Type Joint (RTJ). The flanges feature excellent corrosion resistance, high temperature and high pressure resistance, and reliable sealing performance, making them ideal for critical industrial pipeline systems requiring superior durability and leak-proof connections.

Product Advantages
- Strictly complies with ASME B16.5 standard, ensuring dimensional accuracy, interchangeability, and consistent quality.
- Precision forging process enhances material density, improves mechanical properties, and ensures excellent pressure-bearing capacity.
- Nickel alloy material provides superior corrosion resistance, oxidation resistance, and high-temperature stability, adapting to harsh industrial environments.
- Full pressure class range (Class150-2500) and dual face types (RF/RTJ) meet diverse pipeline connection requirements.
- Weld Neck design ensures firm connection with pipelines, uniform stress distribution, and reduced leakage risk.
- Long service life, low maintenance cost, and high reliability for critical industrial applications.
Installation & Use
Before installation, check the flange surface, bolt holes, and sealing face for scratches, damage, or contamination; clean the welding end and flange sealing face thoroughly. Use gaskets compatible with nickel alloy and the working medium; tighten bolts evenly and symmetrically to ensure uniform pressure and reliable sealing. Conduct a pressure test after installation to confirm no leakage before formal operation.
Precautions
Store in a dry, clean, and ventilated warehouse to avoid moisture, corrosion, and surface scratches; handle with care during transportation to prevent collision and damage to the sealing face. Use within the rated pressure and temperature range; avoid overloading or improper installation. Professional welding and installation personnel are recommended.
