6A 3-1/16 BX-154 10000psi Union Flange

6A 3-1/16 BX-154 10000psi Union Flange – SSM

SSM supplies high-pressure 6A 3-1/16 BX-154 union flanges, specifically designed for oilfield, high-pressure, and industrial piping applications. Rated at 10,000 psi, these flanges provide reliable sealing, durability, and safety under extreme pressure conditions.

Material Composition

6A BX-154 flanges are typically made from high-strength alloy steels, designed for extreme pressure and mechanical stress:

Carbon (C): ≤0.30%

Manganese (Mn): 0.60–1.00%

Chromium (Cr): 0.80–1.20%

Nickel (Ni): 0.25–0.50%

Iron (Fe): balance

Other alloying elements may be added depending on supplier specifications to improve toughness and hardness

This material ensures high tensile strength and impact resistance, suitable for ultra-high-pressure oilfield operations.

Operating Temperature: -46°C to +150°C (depending on material grade)

What is a Union Flange?

A union flange is a two-piece flange system designed for:

Quick assembly and disassembly of pipelines

High-pressure sealing using gasket or metal-to-metal connections

Maintenance of oilfield and industrial pipelines without cutting or welding

The BX-154 6A union flange is widely used in wellhead, oilfield, and high-pressure hydraulic systems.

Advantages

Ultra-high pressure resistance – rated at 10,000 psi
