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.

Key Parameters

  • Material: Nickel Alloy Steel
  • Standard: ASME B16.5
  • Process: Forged
  • Pressure Class: Class150, Class300, Class600, Class900, Class1500, Class2500 (Full Range)
  • Type: Weld Neck (WN) Flange
  • Face Type: Raised Face (RF), Ring Type Joint (RTJ)
  • Features: High strength, corrosion resistant, high temp/pressure resistant, forged structure, reliable sealing
  • Application: Petrochemical, oil & gas, offshore, chemical, power generation, high-pressure industrial piping

Application

Widely applied in petrochemical plants, refineries, offshore platforms, natural gas transmission systems, thermal power stations, and high-pressure industrial pipelines. Suitable for connecting pipelines, valves, pumps, and pressure vessels in harsh working environments (high temperature, high pressure, corrosive media), ensuring stable and safe operation of the entire piping system.

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.

Delivery

Ship within 7–15 working days after order confirmation; shipped by sea, air, or express according to customer requirements. A logistics tracking number will be provided promptly to facilitate order tracking.

Payment Terms

T/T, L/C, Western Union, PayPal; 30% deposit upon order confirmation, balance paid before shipment.

Packing

Anti-rust film wrapping + foam protection + plywood wooden case; shockproof, moisture-proof, and anti-scratch, suitable for long-distance ocean transportation and international shipping.
