Pressure Rating: Class 150
Material: Carbon Steel (A105)
Flange Type: Weld Neck Flange (WN Flange)

🔍 Product Overview:

The A105 Carbon Steel Weld Neck Flange is manufactured according to ASME B16.5 standards and features a 2-inch nominal size and a Class 150 pressure rating. This flange is made from A105 carbon steel, which offers excellent strength and durability in various pressure systems. The weld neck design ensures that the flange is attached securely to the pipe, providing a high level of integrity under pressure conditions. This flange is commonly used in general industrial piping systems where reliable performance and resistance to mechanical stress are essential.

🛡️ Material Advantages – A105 Carbon Steel:

Good tensile strength and durability, ideal for low to medium-pressure systems

Economical material for standard piping systems

Good weldability, enabling secure and robust connections

Widely used in oil and gas, chemical, and water treatment industries

Corrosion resistance suitable for mild environments but should not be used in highly corrosive conditions

⚙️ Flange Features:

Flange Type: Weld Neck Flange (WN Flange) – This type of flange features a long tapered neck that allows for stronger welds to the pipe, offering superior stress distribution and resistance to pressure. It is ideal for high-pressure applications and heavy-duty systems.

Standard: ASME B16.5 – Manufactured to the ASME B16.5 standard, ensuring compatibility with various industrial piping systems and guaranteeing a high-quality connection.

Size: 2 inches – A small but common size used in low-pressure and medium-pressure systems across different industries.

Pressure Rating: Class 150 – Rated for medium-pressure systems (up to 150 PSI at room temperature), offering safe and efficient sealing.

Material: A105 Carbon Steel – A popular material for standard carbon steel flanges, it is highly durable for mild to moderate pressure applications.

Face Type: Raised Face (RF) – The raised face provides an ideal surface for improved sealing in medium-pressure systems.

🏭 Typical Applications:

Chemical Processing: Used in systems that handle non-corrosive chemicals and gases, offering good strength at moderate pressures.

Oil & Gas: Common in onshore and offshore pipelines for transporting oil and gas under moderate pressure conditions.

Water Treatment: Suitable for water treatment plants and municipal water supply systems, where pressure management is necessary.

Power Generation: Applied in steam systems, cooling water lines, and fuel pipelines in power plants.

Food and Beverage: Ideal for non-corrosive food product processing systems where safe and clean connections are critical.
