Product Features
Corrosion Resistance
A179 seamless steel tubes are hot-dip galvanized or treated with rust-proofing treatment, effectively resisting moisture and chemical corrosion, extending their service life to over 15 years.
Dimensional Accuracy
Inner and outer diameter tolerances are controlled within ±0.2 mm, and the wall thickness is uniform, ensuring a tight fit between fittings and equipment.
High-Temperature Resistance
The pipes operate reliably in temperatures ranging from -29°C to 450°C, suitable for steam and hot water transportation, without softening or cracking.

FAQ
Q: What is A179 Seamless Steel Tube used for?
A: A179 seamless steel tubes are primarily used in heat exchangers, condensers, and similar heat transfer systems. They are designed for applications requiring high thermal conductivity and precise dimensions.
Q: What material is A179 steel tube made of?
A: A179 tubes are made from low-carbon steel, with carbon content ranging from 0.06% to 0.18%, and manganese from 0.27% to 0.63%. This composition ensures excellent formability, weldability, and resistance to cracking during cold drawing processes.
Q: What are the typical dimensions available for A179 tubes?
A: A179 tubes are usually available in outside diameters from 6mm to 38mm, with wall thicknesses between 1.2mm and 3.5mm. Lengths are customizable based on project requirements.
Q: How does A179 perform in terms of heat transfer efficiency?
A: Thanks to its thin wall design and clean steel composition, A179 tube offers about 15–20% higher thermal conductivity than standard carbon steel tubes, making it ideal for energy-efficient heat transfer systems.
Q: What are the mechanical properties of A179 seamless tubes?
A: A179 tubes have a minimum tensile strength of 325 MPa and a yield strength of at least 180 MPa. These properties ensure safe operation under moderate pressure and temperature conditions, typically from -45°C to 400°C.
