Features of Inconel 600

Inconel 600 is a nickel-chromium alloy with excellent resistance to organic acids and is used extensively in fatty acid processing. The high nickel content of Inconel 600 provides good resistance to corrosion under reducing conditions, and its chromium content, resistance under oxidizing conditions. The alloy is virtually immune to chloride stress-corrosion cracking. It is also employed widely in the production and handling of caustic soda and alkali chemicals. Alloy 600 is also an excellent material for high-temperature applications requiring a combination of heat and corrosion resistance. The excellent performance of the alloy in hot halogen environments makes it a popular choice for organic chlorination processes. Alloy 600 also resists oxidation, carburization, and nitridation.

This nickel alloy was designed for service temperatures from cryogenic to elevated temperatures in the range of 2000° F. It is non-magnetic, has excellent mechanical properties, and presents the desirable combination of high strength and good weldability under a wide range of temperatures. The excellent mechanical properties of the alloy give this material high strength and good workability. Corrosion resistance is good, especially in alkaline environments, and can be used in both cryogenic and elevated temperature service.

Alloy 600 have corrosion resistance to many kinds of corrosive media. The material produced by JN Alloy are of high quality.Chromium content made it with better corrosion resistance than Nickel 99.2 (alloy200) and Nickel 99.2 ( alloy201,low carbon) in the oxidize environment. Meantime, high Nickel content make this alloy with good corrosion resistance in the reduction condition and alkaline solution, and also effective avoid chlorine-iron stress corrosion cracking. UNS N06600 have good corrosion resistance in the acid, acetic acid, formic acid, stearic acid and other organic acid, with medium corrosion resistance in the inorganic acid. The alloy with excellent corrosion resistance in the first and the second recycling use of the high purity water in the nuclear reactor.

Types of steel pipes

Pipes are classified into two groups as seamless pipes and seamed pipes accordingly to the manufacturing methods. Seamless pipes are formed at one stage during rolling, however seamed pipes require a welding process after rolling. It is possible to classify seamed pipes into two due to the seam geometry as spiral welding and straight welding. Although there is a debate about whether seamless is better than seamed steel pipes, both seamless and welded pipe manufacturers can produce steel pipes providing high quality, reliability, and corrosion resistance. The main focus should be the specifications of the application and cost aspects while determining pipe type.

Seamless Pipes

Seamless pipes are generally made in complex steps starting from drilling hollows from billets, by cold drawing and cold rolling processes. To control outside diameter and wall thickness, seamless type dimension is difficult to control compared to the welded tube, cold work improves the mechanical properties and tolerances. The most significant advantage of seamless pipes is that they can be produced in heavy and thick wall thicknesses. Due to their having no weld seam, makes they to be considered as exhibiting better mechanical properties and corrosion resistance than seamed pipes. Also, a better ovality or roundness is expected from seamless pipes. They are generally preferred to be used under extreme environmental conditions as high loading, high pressure, and high corrosivity.

Welded Pipes

The welded steel pipe is formed by welding a steel plate rolled into a tubular shape by a seam or a spiral seam. Depending on the outer dimension, wall thickness, and application, there are different ways of manufacturing welded pipes. Each method initiates with steel hot billet or flat strips and then made into a pipe by stretching the hot steel billet and forcing the edges together and sealing them with a weld. Seamed pipes offer tighter tolerances but thinner wall thickness rather than seamless pipes. Shorter lead time and lower cost may also be reasons why seamed pipes can be preferred over seamless pipes. However, since weld seam may constitute sensitive areas that may be suitable for any crack to propagate and lead to fracture of the pipe, surface finishing of outside and inside of the pipe should be controlled during production.

In comparison to welded pipes, the seamless variety can bear a pressure of about 20% higher. Hence, the specified seamless quality ASME SB 167 UNS N06600 pipe are compatible with applications that have the need for general corrosion resistance. The temperature range for this alloy is from 2000 °F right down to cryogenic temperatures.  It is their heat resistance properties also make them attractive for several businesses. One such industry is the production of caustic alkalis. Despite the presence of sulfur compounds, ASTM B167 UNS N06600 pipes exhibit good performance and do not break down. Generally, when elemental sulfur is in uninterrupted association with mild steel, it is prone to get attacked by localized corrosion, unlike Inconel 600. The formation of elemental sulfur is a regular affair in sour wells. An oxidation reaction with hydrogen sulfide due to contamination with oxygen what produces sulfur. The precipitation and deposition of sulfur on the walls of the pipe are very common in Sour wells. An excess deposition of sulfur causes regular steel pipes to crack. But, the use of high chromium alloys like Alloy 600 Pipe can delay the rate of corrosion. JN Alloy has an enviable reputation as a supplier of high quality Inconel 600 pipe in China.

Application of Inconel 600 steel pipes

Automotive exhaust pipes

Steel pipes can be designed to fit automotive exhaust systems. If you don’t already know, the exhaust function of a vehicle ensures that the regular exchange of gasses works properly all throughout the combustion process. Oftentimes, the car’s exhaust pipes can be subject to high levels of heat — using steel pipes for this component prevents instances of broken tubing. Steel pipes are hard-wearing, meaning they’re able to retain their shape and function for the car’s exhaust system. Other exhaust pipes can overheat for some time and can place a burden on the vehicle — steel pipes, however, are not. Instead, they offer improved performance for the car and reduce the need for repair or part replacement.

Condenser tubes

Condenser tubes are found in many HVAC systems, pressure vessels, or turbines and they’re typically used for heat exchange. These components need to be inspected ever so often to ensure that no leakages, breakages, or pitting occur. Since steel pipes are highly resistant to corrosion, they make another good choice as condenser tubing material. When pitting occurs in pipes, it’s almost difficult to repair, which is why durable materials such as steel are often used. These problems are also difficult to detect and may cause an entire condenser system to fail. Steel pipes not only prevent instances of this happening, but they’re also relatively easy to install. If there are any replacements that need to be done on existing tubing, steel pipes can be safely carried and attached using the right fittings.

Industry of Construction

This is one of the most obvious uses for steel pipes. They are preferred by many construction companies because Inconel 600 are pliable and sturdy. Steel pipes are utilized as building piles when the soil is too thin to support the weight of big structures. The structure itself, as well as its architectural style, are frequently included. In fact, construction companies are one of the major steel pipe buyers.

Oil and Gas

Many steel pipes are specifically designed for use in the oil and gas industry. Due to their extensive range of benefits during the transport of hazardous materials, crude oil, and natural gas, they play a key role in the transfer of products. Inconel 600 is popular for its wide range of benefits over other materials. Not only is it high strength, relatively lightweight, and resists corrosion, but it also is easier to weld and stays relatively maintenance-free for a long period of time. Its ability to withstand high pressure and temperatures, as well as its lifespan underwater, makes it ideal for the movement of products in oil and gas worldwide. Its trustworthiness has been put to the test and regularly meets the mark.
