Stainless Steel 317 Heat Exchanger Tube Manufacturer, Supplier in India

Stainless steel 317/317L heat exchanger tubes find extensive use in various industries and applications due to their exceptional performance and durability. One prominent application is in the chemical and petrochemical industry, where these tubes are employed in heat exchangers for processing and refining corrosive chemicals, acids, and solvents. The pharmaceutical and biotechnology sectors also utilize stainless steel 317/317L heat exchanger tubes to resist contamination and withstand sterilization processes.

Additionally, these tubes are widely employed in power generation plants, including nuclear, fossil fuel, and geothermal facilities, due to their excellent high-temperature and corrosion resistance properties. Other industries that benefit from stainless steel 317/317L heat exchanger tubes include oil and gas, food and beverage, pulp and paper, and wastewater treatment, where the tubes play a vital role in efficient heat transfer and maintaining product integrity.

What are the key properties and characteristics of stainless steel 317/317L heat exchanger tubes?
Stainless steel 317 heat exchanger tubes possess a range of key properties and characteristics that make them highly suitable for various applications. One notable feature is their excellent corrosion resistance, particularly in environments containing sulfuric acid, acetic acid, and other aggressive chemicals. This corrosion resistance is enhanced by adding molybdenum, which also improves the alloy's resistance to pitting and crevice corrosion. Another crucial property of stainless steel 317 heat exchanger tubes is their exceptional high-temperature strength, allowing them to withstand elevated operating temperatures without compromising structural integrity.

Stainless steel 317L heat exchanger tubes possess a range of key properties and characteristics that make them highly suitable for various applications. One significant feature is their exceptional corrosion resistance, particularly in harsh environments containing chlorides, sulfuric acid, and other corrosive substances. Adding molybdenum and low carbon content further enhances their resistance to localized corrosion, such as pitting and crevice corrosion. Moreover, stainless steel 317L heat exchanger tubes exhibit excellent resistance to high-temperature oxidation, making them suitable for applications involving elevated temperatures.

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.
