Alloy Steel Girth Flange In Heat Exchanger ASME SA266 GR.2N Custom Made

Alloy Steel Girth Flange ASME SA266 GR.2N Custom Made Flange for Heat Exchanger

Overview

A Girth Flange is a circular flange designed to connect cylindrical sections of piping, pressure vessels, or storage tanks. It ensures a secure and leak-proof joint by bolting two mating flanges together with a gasket in between. Girth flanges are widely used in industries such as oil & gas, petrochemical, power generation, and water treatment due to their robust construction and reliable performance.

Key Features

• High Strength & Durability: Manufactured from high-quality materials (carbon steel, stainless steel, alloy steel, etc.) to withstand high pressure and temperature conditions.

• Precision Engineering: Designed to meet international standards (ASME B16.5, EN 1092-1, API 605, etc.) for dimensional accuracy and compatibility.

• Excellent Sealing Performance: Compatible with various gasket materials (rubber, PTFE, spiral wound, metal ring) to prevent leaks.

• Easy Installation & Maintenance: Allows for quick assembly and disassembly, reducing downtime in industrial operations.

Applications

1. Oil & Gas Pipelines

Connecting large-diameter pipes in refineries and transmission systems.

2. Pressure Vessels & Storage Tanks

Joining cylindrical sections in reactors, boilers, and LNG tanks.

3. Heat Exchangers (Key Application)

In shell-and-tube heat exchangers, girth flanges play a critical role in:
✔ Connecting the Shell Sections: They allow for the assembly of multiple shell sections, ensuring structural integrity under thermal and pressure loads.
✔ Facilitating Maintenance & Cleaning: Girth flanges enable easy disassembly for tube bundle inspection, cleaning, or replacement.
✔ Ensuring Leak-Free Performance: Properly sealed girth flanges prevent fluid leakage between the shell side and tube side, maintaining heat transfer efficiency.
✔ Handling Thermal Expansion: They accommodate thermal stresses caused by temperature variations during operation.

4. Power Plants

Used in steam and water piping systems.

5. Chemical Processing

Resistant to corrosive environments in acid and alkali transport.
