Description

​​TEMA Class R BEM Heat Exchanger, Fixed Tubesheet, NACE SA179 tube for Sour Gas Refinery Service

Yuhong Holding Group Co., Ltd is a globally recognized leader in the manufacturing and supply of industrial equipment, including heat exchangers, fired heaters, air coolers, and their critical components. With decades of expertise and a commitment to delivering the highest quality products, we serve customers across various industries worldwide.

Among our premium offerings is the ASTM SA179 Seamless Carbon Steel Tube, specifically designed for Fixed Tube Sheet Heat Exchangers. Renowned for its excellent thermal conductivity, durability, and reliability, SA179 seamless tubes are the ideal choice for efficient and long-lasting heat exchanger systems.

1. ASTM SA179 Chemical Composition and Mechanical Properties

Element Composition (%)
Carbon (C) ≤ 0.06
Manganese (Mn) 0.27–0.63
Phosphorus (P) ≤ 0.035
Sulfur (S) ≤ 0.035

The low carbon content in SA179 minimizes the risk of carbide precipitation, ensuring superior ductility and weldability while maintaining excellent thermal conductivity.

Property Value
Tensile Strength ≥ 325 MPa (47,000 psi)
Yield Strength ≥ 180 MPa (26,000 psi)
Elongation ≥ 35%
Hardness ≤ 72 HRB

These mechanical properties ensure that SA179 seamless tubes can withstand high pressures and temperatures while maintaining structural integrity and efficient heat transfer.
