ASME Class 150 Flanges Manufacturer/Exporter in India

Flanges may not always get the spotlight, but they play a crucial role in keeping industrial piping systems safe, connected, and easy to maintain. Among all flange pressure ratings defined under ASME standards, the ASME Class 150 flange is by far the most widely used. It offers an excellent balance of strength, cost, and availability — making it ideal for low- to medium-pressure applications across major industries.

At World Rings, we specialize in forging high-quality ASME Class 150 flanges engineered to handle demanding working conditions with consistency and reliability.

What Is an ASME Class 150 Flange?

“Class 150” refers to a pressure rating defined in ASME B16.5, covering flanges from ½" to 24". A Class 150 flange typically handles up to 285 psi (19.6 bar) at 100°F, with pressure capacity reducing as temperatures increase. These flanges are preferred for systems that may not be extremely high-pressure but still require secure sealing and long service life.

Where Are They Used?

Class 150 flanges are found across:

• Oil & gas pipelines
• Chemical and petrochemical plants
• Water and wastewater treatment
• Power generation systems
• HVAC and fire protection networks
• Marine cooling and fuel systems

Their versatility and ease of installation make them a universal choice.

Manufacturing at World Rings

At World Rings, every flange begins with closed-die forging, improving grain flow and mechanical strength. We manufacture in materials such as:

• Carbon Steel: A105, A350 LF2
• Alloy & Duplex Steels: F11, F22, F51, F53, F55
• Special Alloys on request

Each flange undergoes heat treatment, CNC machining, and strict quality checks including UT/MPI, hardness, hydrotesting, and dimensional verification.
