ASTM A179 Carbon Steel Heat Exchanger Tube

ASTM A179 Carbon Steel Heat Exchanger Tube Manufacturer, Supplier in India

ASTM A179 and ASME SA179 are standards developed by the American Society for Testing and Materials (ASTM) and the American Society of Mechanical Engineers (ASME), respectively. These standards specifically pertain to heat exchanger tubes. Heat exchanger tubes are crucial components in various industrial processes that involve the transfer of heat from one fluid to another.

ASTM A179 and ASME SA179 establish the specifications and requirements for seamless cold-drawn low-carbon steel tubes used in heat exchangers. These standards ensure that the tubes meet specific mechanical properties, dimensions, and tolerances necessary for efficient heat transfer and safe operation. By adhering to ASTM A179 / ASME SA179, manufacturers and users can ensure the quality, reliability, and compatibility of heat exchanger tubes in various applications, including power generation, chemical processing, oil and gas, refrigeration, etc.

What are the key specifications and requirements for ASTM A179 / ASME SA179 heat exchanger tubes?

ASTM A179 sets forth the key specifications and requirements for heat exchanger tubes. These tubes are made from seamless cold-drawn low-carbon steel, ensuring excellent thermal conductivity and corrosion resistance. The standard specifies the chemical composition of the steel, which typically includes elements such as carbon, manganese, phosphorus, and sulfur, with strict limits to ensure desired properties. Additionally, the mechanical properties of the tubes, such as tensile strength, yield strength, and elongation, are outlined to guarantee structural integrity and durability. ASTM A179 also prescribes dimensional requirements, including outer diameter, wall thickness, and length, to ensure compatibility and ease of installation.

Drawing/ Floating Process

Pulling a metal bar, rod, or wire through the entirety of a die to change its finish, shape, size, and/or mechanical qualities is known as floating or drawing. The tube's outer, inner, and wall thicknesses are all reduced via the tube drawing procedure. Stainless steel tubes benefit from maintaining the integrity of their surface.

Continuous Heat Exchanger Tube Mills

The production of Heat Exchanger tubes has been transformed by continuous tube mills. These mills do away with the necessity for forging welding or filler metal, in contrast to conventional procedures. With the use of this technology, Heat Exchanger pipes and tubes may be produced continuously, increasing productivity while lowering costs and improving efficiency.

Continuous Casting

A notable advancement in the production of Heat Exchanger tubes is continuous casting. The metal is solidified into a continuous billet through the continuous pouring of molten metal into a water-cooled mould. Better uniformity and enhanced mechanical qualities are guaranteed by this continuous casting technique for the tubes.

Annealing

Metal is heated above the point of re-crystallization and cooled to room temperature during the annealing process. The molecular bonds in metal tighten when it is shaped, making it rigid. The metal is put through an annealing process to regain its ductility.

Sinking Process

Tube sinking is a drawing technique that reduces the diameter of tubes. In this drawing technique, a tube is run through a die without the need of a mandrel. Good inner surface quality is not ensured when using a mandrel. The die angel determines the integrity of the outer surface. The die being used produces a uniform surface. A tube can be significantly smaller than it was originally. When cost is a factor, tube sinking is ideal.
