Alloys of Inconel are well known for their ability to tolerate heat across the world and have various tubes and pipes made from them. One such tube is the ASTM B704 Welded Tube. The nickel alloyed tube is welded in this specification. ASTM B704 UNS N06625 Welded Tube is widely used in applications such as boilers, condensers, and heat exchangers. The main reason behind using Nickel SB 704 N08825 Tubing in these applications is that they expose the tubes to fluctuating temperatures. Hence ASTM B704 N06625/N08825 tubes are considered useful in applications where temperatures are high as well as low.
Generally, the alloy used in ASTM B704 Welded Tubing is said to have a higher performance and is hence considered to be expensive. However, when compared to the seamless version of the ASTM b704 ERW tube they are comparatively cheaper. Moreover, these tubes are welded with a single vertical weld hence the manufacturing cost is lower in practicality.
ASTM B704 Inconel Incoloy Alloy Welded Tube has decent resistance to sulfuric acid, phosphoric acid, and seawater. These tubes are also resistant to oxidizing and reducing acids. ASTM B704 Inconel 625 Welded tubes are used in oil and gas piping, pollution control equipment, acid production, pickling equipment, and so on. They have a stable austenite structure and the high nickel content in ASTM B704 Inconel Tubing helps it in resisting chloride ion stress corrosion. Pickling and rinsing the tubes post heat treatment helps in obtaining maximum corrosion resistance.
