Monel 400 piping systems for sea water applications

Nickel-copper-based alloy 400 Monel 2.4360 cold drawn rod is virtually immune to chloride stress-related corrosion cracking when exposed to corrosive media in typical environments. Monel 400 is a copper and nickel based alloy that is popular today due to its high performance. The alloy has excellent acid and alkali resistance. In addition, it has good tensile strength, ductility, excellent thermal conductivity, and can be hardened by cold work. Additionally, it can be used in applications with temperatures ranging from minus to 538 degrees Celsius.

Nickel Alloy 400 and Monel 400, also known as UNS N04400, is a ductile nickel-copper-based alloy consisting primarily of two-thirds nickel and one-third copper. Nickel Alloy 400 is known for its resistance to a variety of corrosive conditions, including alkalis (or acids), salt water, hydrofluoric acid, and sulfuric acid. Since Monel 400 or Alloy 400 is a cold worked metal, this alloy has high hardness, stiffness and strength. By cold working ASTM B164 UNS N04400 bar stock, the alloy is subjected to higher levels of mechanical stress, which in turn causes changes in the alloy’s microstructure.

A threaded rod, also known as a stud, is a relatively long rod that is threaded on both ends; the thread may extend along the complete length of the rod. They are designed to be used in tension. Threaded rod in bar stock form is often called all-thread.

A high nickel alloy with the addition of substantial amounts of copper to give the alloy excellent resistance to sodium chloride solutions, including brine and seawater. Therefore, UNS N04400 Alloy 400 Forged Fittings and Socket Weld Elbows can be used as part of an offshore piping system that may require a change of direction.

Alloy 400 is resistance to neutral, alkaline and acid salts is shown, but poor resistance is found with oxidizing acid salts such as ferric chloride.

While it is a very useful metal, it is cost prohibitive in most applications. Monel 400 costs 5 to 10 times as much as regular nickel or copper.

Monel K500 Fasteners are thermally applied or manipulated to affect precipitation. This process is called age hardening. These fasteners have a greater tendency to stress corrosion cracking in a variety of harsh environments when exposed to the age hardening process. It has three times the yield strength compared to the standard version. Monel 500 material is an age-hardenable nickel-copper alloy that combines the corrosion resistance of Alloy 400 with the high strength corrosion fatigue and erosion resistance.

Monel 400 is a kind of corrosion resistant alloy with large dosage, wide use and excellent comprehensive performance. Monel 400 has excellent corrosion resistance in hydrofluoric acid and fluorine gas medium.

Monel K500 nuts are a result of an age hardening process where aluminum and titanium are added to the nickel-copper base and then precipitated throughout the matrix.

Monel K500 fasteners are precipitation hardenable nickel and copper based alloy fasteners. These fasteners were developed for excellent corrosion resistance and have high hardness and strength. ALLOYK500 is a nickel-copper alloy that is age-hardened by the addition of aluminum and titanium alloys.

Monel K500 Threaded Flanges (UNS N05500) has resistant to a sour ¨C gas environment. Monel K500 Slip On Flanges is often used in Chemical Process Industry: such as in processes involving organic acids, caustic soda and dry chlorine, production of chlorinated plastics, and more.

Monel 400 is corrosion resistant to most salts, water, alkalis, organic substances, food products, and atmospheric conditions at both normal and elevated temperatures.

Monel 400 or also known as Nickel-Copper 400 is a solid solution alloy that is a high strength material that can be used over a wide temperature range. It also has excellent corrosion resistance and has applications in many areas in marine and chemical processing. It is used in applications such as valves, pumps, fresh water tanks and propeller shafts.

The alloy is slightly magnetic at room temperature. Monel 400 is widely used in the chemical, oil and marine industries.

Monel400 Copper-nickel alloy (UNSN04400) is a soft Copper-nickel alloy that is resistant to various corrosive environments.

Monel K500 Bolts, also known as Alloy K500, are composed of a nickel alloy that combines the excellent corrosion resistance of Monel 400 with increased strength and hardness. These additional properties of Monel K500 bolts are the result of an age hardening process in which aluminum and titanium are added to a nickel-copper matrix, which is then precipitated throughout. Compared to 400, this process increases the yield strength of K500 by a factor of approximately 3 (110ksi vs. 45ksi) and doubles the tensile strength (160ksi vs. 83ksi). Monel K500 bolts will maintain their strength down to 1200¡ãF and even maintain their ductility down to -400¡ãF.

The chemical composition of Monel K500 Nippo Flanges provides great resistance to a lot of corrosive environments, such as pitting, crevice corrosion, inter ¨C granular corrosion, and stress ¨C corrosion cracking. Monel K500 Spacer Flanges has useful resistance to boiling sulfuric acid up to 40 % concentration, to 60 % concentration at 176 Degree F and in all concentrations to 150 Degree F.

It exhibits excellent weldability and can withstand very large amounts of pressure and weight.

There are different pressure classes of these flanges ranging from Class 150 Monel UNS N04400 Flanges to class 2500, and PN6 to PN64.

Monel 400 is well known for its high strength and corrosion resistant properties. It works in a wide range of temperatures, and is available in multiple forms for a variety of products. Monel 400 is used extensively in (for pipe) piping. Resistant to both steam and seawater, its toughness and anti-corrosive properties make it perfect for heavy duty applications such as transfer (pipe) piping used in oil refineries.

Monel 400 and K500 nuts also exhibit excellent corrosion resistance in marine applications and have reasonable corrosion resistance to sulfuric and hydrochloric acids under reducing conditions. A standout feature of monel nuts is their excellent resistance to hydrofluoric acid, a particularly difficult acid to handle, at all concentrations up to the boiling point. For hydrofluoric acid applications, Monel nuts are probably the most corrosion resistant of all commonly used specialty alloys.

Monel K500 alloy has excellent corrosion resistance, and has higher strength and hardness than Monel 400. This is due to the addition of elements such as Al and Ti to the alloy, and after a certain heat treatment, there are dispersed intermetallic compounds on the substrate.

Alloy K500 is refined by Electroslag Refining (ESR), ensuring the cleanest and highest quality material. This increased alloy purity limits the potential for hard non-metallic inclusions that can increase machining difficulty, machining time and ultimately lead to part failure.
