Alloy Steel Flanges

Product Overview

Alloy Steel Flanges are precision-engineered components designed to connect pipes, valves, pumps, and other equipment in high-stress piping systems. Manufactured from specially blended steel alloys, these flanges offer superior mechanical properties compared to standard carbon steel, particularly in high-temperature and high-pressure environments. They provide a reliable, leak-proof connection point that allows for easy assembly, maintenance, and inspection of complex piping networks. Each flange is forged and heat-treated to ensure a dense, uniform grain structure that delivers consistent performance in the most demanding industrial applications.

Technical Specifications

Common Uses

1. Oil & Gas Refineries: Connecting high-temperature crude oil and distillation units.

2. Power Plants: Joining boiler tubes, steam lines, and superheater piping.

3. Petrochemical Facilities: Handling aggressive hydrocarbons and process chemicals.

4. High-Pressure Steam Systems: Ensuring safe connections in industrial boilers.

5. Offshore Platforms: Withstanding harsh marine environments and high-pressure flows.

6. Heat Exchangers: Providing secure inlet and outlet connections for thermal equipment.

Key Benefits

1. Handles Extreme Heat: Maintains structural strength in continuous high-temperature service, unlike standard steel.

2. Withstands High Pressure: Engineered for heavy-duty applications up to Class 2500 pressure ratings.

3. Long-Term Reliability: Resists creep, fatigue, and thermal shock over decades of use.

4. Secure Connections: Precision machining ensures a tight, leak-proof fit every time.

5. Cost-Effective for Critical Use: Reduces downtime and failure risks in valuable industrial systems.

Main Feature

1. Forged Construction: The forging process creates a dense grain structure that follows the flange shape for maximum strength.

2. Heat-Treated for Stability: Undergoes normalizing or quenching and tempering to remove internal stresses and improve toughness.

3. Precision Machined Surfaces: Gasket sealing surfaces are machined to exact specifications for reliable sealing.

4. Full Traceability: Each flange is marked with grade, heat number, and pressure class for quality assurance.

5. Corrosion-Resistant Alloy: Contains chromium and molybdenum to resist oxidation and scaling at elevated temperatures.

6. Standardized Dimensions: Manufactured to ASME B16.5 and B16.47 specifications for global interchangeability.
