ASME I

Overview & Scope

ASME Section I governs the design, fabrication, and inspection of power boilers used for generating steam at pressures above 15 psi. These boilers are critical in power generation, industrial heating, and process applications.

Certification: ASME S, E & M Stamp

Pressure Range: > 15 psi

Application: Steam generation & power systems

Inspection: Mandatory Authorized Inspector

Key Features

Strict safety-focused design approach
Mandatory safety valve sizing
Applicable to steam and vapor generating systems
Used in power plants and industrial boilers
Comprehensive inspection and certification process

Key Components Covered

Steam Drums: Pressure vessels for steam-water separation
Headers: Distribute fluid across multiple tubes
Boiler Tubes: Water-tube and fire-tube configurations
Safety Valves: Overpressure protection systems
HRSG: Heat Recovery Steam Generators in power plants

Material Standards

SA-106 (Piping)
SA-516 (Drums)
SA-213 (Boiler Tubes)

Safety & Inspection

Mandatory safety valve sizing (PG-67 to PG-73)
Continuous inspection by Authorized Inspector
Hydrostatic pressure testing
Strict compliance with ASME BPVC

Applications

Power generation plants
Industrial steam systems
Refineries and petrochemical plants
Heat recovery systems (HRSG)

ASME Certification

ASME Section I certification includes S Stamp for power boilers, E Stamp for electric boilers, and M Stamp for miniature boilers. Certification ensures compliance with strict safety, design, and inspection requirements.
