1-1/2 inch Carbon Steel 477 1G Gas Press Flange Adapter

1-1/2" Carbon Steel Flange – Class 150 for Industrial and Mechanical Piping

The Apollo PowerPress 1-1/2" Carbon Steel Flange is engineered for secure, high-integrity mechanical connections in non-potable water, HVAC, and industrial gas systems. Fabricated from ASTM A105 forged carbon steel, this flange is pressure-rated to ANSI B16.5 Class 150 standards, making it ideal for low- to moderate-pressure systems requiring a robust bolted flange connection.

This model is specifically designed for use with compatible press adapters and flange gaskets to ensure a tight, leak-resistant seal. Its durable construction and flat-faced design make it suitable for demanding mechanical piping installations where strength, dimensional accuracy, and corrosion resistance are essential.

Key Performance Features

• Material: Forged Carbon Steel (ASTM A105)
• Nominal Size: 1-1/2 inch
• Rating: ANSI B16.5 Class 150
• Face Type: Raised Face or Flat Face depending on model spec
• Finish: Black oxide or anti-corrosive coating
• Bolt Hole Pattern: Standardized to ASME flange drilling for universal compatibility

Installation and Application

Installation requires proper bolt torque sequencing and the use of suitable gaskets based on the system media. The flange is designed for press-to-flange transitions using compatible adapters and is commonly used in mechanical rooms, boiler lines, and high-volume fluid distribution systems.

Where It's Used

• Hydronic heating systems
• Commercial HVAC piping
• Industrial fluid and gas transport
• Low-pressure steam service (verify with code requirements)

Contractor Tip

Always verify system pressure ratings and media compatibility when selecting carbon steel flanges. For enhanced corrosion resistance, consider applying dielectric isolation kits or selecting flanges with zinc-plated finishes in aggressive environments.

The Apollo 1-1/2" Carbon Steel Class 150 Flange is a critical component for ensuring durable, code-compliant piping assemblies. Built for strength and precision, it's the professional choice for mechanical contractors working in commercial or industrial environments where dependability matters.
