Product Overview
ASME SA179 Carbon Steel Boiler Tube is a specification for seamless carbon steel tubes specifically designed for heat exchangers, condensers, and boiler systems. These tubes excel in moderate-temperature, lower-pressure environments compared to higher-grade steels like ASME SA192.
SA179 is an ASME (American Society of Mechanical Engineers) standard for seamless cold-drawn carbon steel tubes, ideal for heat transfer applications with moderate temperature and pressure conditions.
Chemical Composition
- Carbon: 0.06-0.15%
- Manganese: 0.27-0.63%
- Phosphorus: ≤ 0.035%
- Sulfur: ≤ 0.035%
- Silicon: 0.10-0.35%
Mechanical Properties
- Tensile Strength: 45,000-70,000 psi (310-480 MPa)
- Yield Strength: 25,000 psi (172 MPa)
- Elongation: Minimum of 30% in 8 inches (200 mm) of gauge length
- Hardness: Relatively low, contributing to excellent formability and resilience in heat transfer applications
Key Features
- Cold-Drawn Seamless Construction: Manufactured without seams for superior structural integrity under internal pressures
- Optimized Performance: Designed for lower pressure and temperature resistance compared to higher-grade boiler tubes
Applications
- Heat Exchangers: Efficient thermal transfer in low- to medium-pressure systems
- Condensers: Power plant condenser units and industrial steam cooling systems
- Boilers: Low-pressure boiler designs with moderate temperature requirements
- Steam Generators: Moderate pressure steam generation in smaller systems
- Water-Filled Systems: Water-based systems requiring moderate pressure and temperature conditions
