ASTM A179 Seamless Tubing, a cold-formed low-Carbon Steel Tube specially designed for tubular heat exchangers, condensers, and similar heat transfer applications, is a remarkable product that perfectly complements Baodely Huaian Metal Technology Co., Ltd.'s extensive range of Main products，which includes Carbon Steel Pipe, Low Temperature Steel Pipe, Boiler Pipe, Alloy Steel Pipe, High Temperature Steel Pipe, and Precision Steel Pipe.​

This standard ASTM A179 specifies seamless, cold-drawn carbon steel tubes with minimum wall thickness, ensuring high mechanical strength and thermal efficiency, characteristics that align with the high-quality standards maintained across the company's product line, from Carbon Steel Pipe to High Temperature Steel Pipe.​

Key Features:​
Material Composition​
It complies with strict chemical requirements for carbon (≤0.25%), manganese (0.25-0.60%), phosphorus (≤0.045%), and sulfur (≤0.050%). May also include alloying elements to enhance performance in specific environments, similar to how Alloy Steel Pipe in the company's portfolio uses alloying elements to boost performance. This careful composition ensures it can work harmoniously with other products like Boiler Pipe in complex industrial systems.​

Mechanical Properties​
With a tensile strength of 325 MPa (47,000 psi), yield strength of 180 MPa (26,000 psi), elongation of 35%, and controlled hardness for ductility and deformation resistance, ASTM A179 Seamless Tubing exhibits impressive mechanical properties. These properties make it a reliable choice, comparable to the strength performance that Low Temperature Steel Pipe offers in low-temperature environments and High Temperature Steel Pipe provides under high heat conditions.​

Dimensions and Tolerances​
Its outer diameters range from 3.2 mm (1/8 in.) to 76.2 mm (3 in.), with wall thicknesses as thin as 0.4 mm (0.015 in.). The tight tolerances on diameter (±0.2 mm) and wall thickness (±0.02 mm) ensure precision in heat exchanger designs, a feature that resonates with the precision of Precision Steel Pipe in the company's product range, which is known for its accurate dimensions.​

Testing and Quality Assurance​
Mandatory tests including flattening, flaring, flange, and hydrostatic pressure tests are conducted to validate structural integrity. Non-destructive testing (NDT) and chemical analysis are also performed to meet industry standards, a rigorous quality control process that is consistent with how the company ensures the quality of its Boiler Pipe and other key products.​

Applications​
Widely used in industrial heat exchangers, condensers, and boilers due to its excellent thermal conductivity and corrosion resistance, it is suitable for high-pressure and high-temperature environments up to 450°C (842°F). This makes it a perfect match for Boiler Pipe in boiler systems, working together to ensure efficient and safe operation. It also finds synergy with High Temperature Steel Pipe in high-temperature applications, further expanding the company's ability to provide comprehensive solutions for various industrial needs.​

Surface and Finishing​
Available in various finishes, including satin, hairline, mirror polish, or protective coatings (e.g., passivation, phosphating) to enhance durability and compatibility with different media, similar to the surface treatment options offered for products like Alloy Steel Pipe to improve their performance in specific environments.​

Packaging and Delivery​
Typically supplied in export-standard packaging (e.g., plastic sleeves) with delivery timelines of 15-30 days, ensuring that it reaches customers in optimal condition, just like the reliable packaging and delivery services provided for all the company's Main products.​

This specification balances cost-efficiency with performance, making ASTM A179 a preferred choice for manufacturers requiring reliable and versatile heat exchange solutions, and it serves as a valuable addition to Baodely Huaian's diverse product portfolio, alongside Carbon Steel Pipe, Low Temperature Steel Pipe, Boiler Pipe, Alloy Steel Pipe, High Temperature Steel Pipe, and Precision Steel Pipe.
