Inconel Pipes

Inconel belongs to the austenitic, nickel-chromium superalloy family. Inconel pipes are well-known for their oxidation and corrosion resistance. Inconel pipes are usable effectively in high-pressure and heat environments. Inconel is used when aluminium and regular steel succumb to creep rupture.

Solid solution strengthening or precipitation hardening gives Inconel its high-temperature strength. Inconel pipes are known to retain their strength over a wide range of temperatures, which makes them usable in high-temperature applications effectively. It is mainly used in extreme environments, such as gas turbine parts. The passivating layer over Inconel's surface helps protect from high-temperature damage. Machining cannot be carried out on Inconel, and forming is also complex in this alloy. Inconel pipe is used in many applications, such as chemical processing, heat exchangers, gas turbine blades, pressure vessels, steam generators, pump motor shafts, turbocharger rotors and seals, combustors, and pressurised water reactors in nuclear plants. Many marine applications also use Inconel due to its resistance to sodium chloride in various temperatures.

Inconel pipes are formed from a combination of nickel and chromium, making them resistant to corrosion and pitting. They are known for their high Inconel pipe price, but they often measure up to the quality in terms of longevity. Inconel pipes have a unique set of characteristics that sets them apart from similar materials such as titanium, aluminium, copper and carbon alloy, including higher temperature tolerance, superior strength and robust construction up to 2000°F. An Inconel pipe's composition is typically between 58% to 72% Nickel, with other trace elements such as Chromium, Molybdenum, Silicone and Aluminum added to achieve the desired properties. These pipes offer excellent reliability at affordable rates, making them a great choice for many industries.

Inconel pipes are becoming increasingly popular in various industries due to their excellent properties – they are incredibly durable and retain their strength, even at extremely high temperatures and under corrosive influence. They have excellent weldability and can often be flexibly bent or re-formed into complex shapes. Many Inconel pipe manufacturers specialise in producing and delivering Inconel pipes of all shapes and sizes for use in various applications, from power plants to petroleum refineries. With its great flexibility, Inconel piping can be used to create tubing systems providing the ideal solution for multiple needs.

FAQ's for Inconel Pipes

Inconel pipes fall under the American Society of Mechanical Engineers (ASME) code B36.10M. This code categorizes pipes based on their sizes, wall thicknesses, material grades and standards for pressure test ratings. Manufacturers also use various international standards such as ASTM, ANSI and JIS to provide additional detail about the pipes.

Inconel pipes are made of special alloys, such as those marked with the code 88-2-9. These alloys resist corrosion and high temperatures, making them ideal for harsh conditions like those in chemical plants. Other codes found on Inconel pipes may include 88-25-4, 88-25-5 and 88-2NiCrMoCuNbTi. You can find more information about these materials on the ASME website or from your metal supplier.

Inconel pipe welding typically uses the gas metal arc (GMA) or shielded metal arc (SMA) processes. GMA welding requires a direct current power source, whereas SMA welding uses alternating current. GMA welding is preferred for its precision and speed, but it generates more heat than SMA welding and can cause more warping of the pipes. A qualified welder should be consulted to determine the best process for your pipes.

Inconel pipe schedule charts are used to determine the size and wall thickness of Inconel pipes. This chart includes the nominal pipe sizes, outer diameter (OD), wall thickness (WT) and corresponding weights for standard schedules 5 through XXS. The OD and WT values are based on ASME B36.10M and ANSI B36.19M for pipes with pressures up to 10,000 pounds per square inch. The schedule charts also include class designations that indicate a particular pipe's pressure rating.

Inconel pipe sizes range from 1/8" up to 24" in seamless and welded construction. The most common wall thicknesses are either Schedule 10 or Schedule 40, but other wall thicknesses may be available depending on the application. Inconel pipes can also come in different diameters, such as imperial (inch) and metric sizes.

Inconel pipe specifications include the material grade number, chemical composition, mechanical properties, and other process-specific requirements. When referencing Inconel pipes for industrial use, the ASTM B444 or ASTM B829 standards will often be referenced as these are the most commonly used in industry. These specifications cover seamless and welded Inconel pipes which can be used for various applications such as piping systems and heat exchangers. Additionally, the ASME Boiler Code (ASME B31) has specific requirements that must be met to meet safety regulations.

Inconel pipes have a maximum pressure rating of up to 1,800 psi for seamless pipe and up to 6,000 psi for welded pipe, depending on the range and wall thickness. Inconel pipes are solid and durable, making them suitable for high-pressure applications like those in oil and gas pipelines. They also possess excellent corrosion resistance, making them ideal for use in marine, offshore and chemical processing environments.
