Descrição do produto

ASME SA179 A179 Carbon Steel Cold Drawn Steel Heat Exchanger Tube Coil for Industrial Boiler Economizer & Heat Exchanger Systems

The core application of A179 material is in economizer tube bundles for power plants/industrial boilers: boiler feedwater flows inside the tubes, while high-temperature flue gas exits from the boiler flows outside.

Using the waste heat of the flue gas to preheat the feedwater reduces the exhaust gas temperature, improves boiler efficiency, and brings the feedwater temperature closer to the boiler drum wall temperature, reducing temperature fluctuations.

A179 material is resistant to medium temperatures and has good thermal conductivity, making it a classic material for economizers. It is less expensive than stainless steel and suitable for medium- and low-temperature flue gas conditions.

Custom-designed economizer tube bundles, made of A179 material and featuring a uniquely shaped coil structure, are specifically designed to recover waste heat from flue gas and heat boiler feedwater. They are key components for improving efficiency in thermal power plants and industrial boilers.

Chemical Composition
Element	Composition (wt%)
Carbon (C)	0.06 – 0.18
Manganese (Mn)	0.27 – 0.63
Phosphorus (P)	≤ 0.035
Sulfur (S)	≤ 0.035
Silicon (Si)	≤ 0.25

Mechanical Properties
Property	Requirement (min.)
Tensile Strength	≥ 325 MPa (47 ksi)
Yield Strength (0.5% extension under load)	≥ 180 MPa (26 ksi)
Elongation (in 2 in / 50 mm)	≥ 35%
Hardness (Rockwell B)	≤ 72 HRB

Differences between standard U-shaped tubes

Item	U-Tube	Serpentine Tube Bundle
Structure	Symmetric U-bend, fixed to one tube sheet	Continuous multi-bend/coiled, no common tube sheet
Application Scenario	Shell-and-tube heat exchangers	Boiler flue gas heating surfaces (economizer/superheater)
Key Benefit	Thermal stress relief for shell-and-tube units	Maximized heat transfer area & optimal flue duct fit

Application:

Boiler Economizers: For power plants and industrial boilers to recover flue gas waste heat.
Heat Exchangers: Used in oil & gas, chemical, and food processing industries.
Waste Heat Recovery Systems: Maximizing energy efficiency in industrial production lines.

The normalized state of these flanges is highly uniform. We found no grain issues during subsequent NDT testing, and they fit the shell perfectly.

Robust construction suitable for our tough operating environment. The vessel handles our coal-to-liquid hydrogenation process with Fischer-Tropsch syncrude—highly corrosive service. The internal cladding overlay (E309L/E347) has shown zero defects after 18 months operation. We appreciate the comprehensive spare parts list and recommended maintenance schedule. The manufacturer even provided on-site supervision during our first catalyst loading. Good value for African market conditions.

Technical bid included HTRI thermal simulation with fouling factor 0.0002 m²·K/W for our naphtha hydrotreater. SA516 Gr485 + 1.25Cr-0.5Mo tube combination optimized for high-temperature hydrogen sulfide resistance. Delivery EXW Qingdao to CIF Ulsan was 22 days, door-to-door. Zero NCRs during FAT. Korean PM assigned spoke technical English fluently. Already approved for Phase 2 EPC.
