Application and Properties of Monel 400 Pipes and Tubes

What are Monel 400 Pipes?

The Monel 400 pipe, as expected of a nickel-based alloy, has properties such as good corrosion resistance, good weldability, and high tensile strength. Because the alloy work hardens during machining, Monel Pipe is difficult to machine. Welding techniques used on the 400 Monel Pipe include gas arc welding, gas metal-arc welding, metal arc welding, and submerged arc welding. Monel 400 ERW Pipe welding includes the use of appropriate filler metals.

It is not necessary to perform a post-weld heat treatment. Even though the 400 Monel ERW pipe must be thoroughly cleaned after welding the alloy. Because UNS N04400 Tubing has a high melting point of 1350 degrees Celsius, it can be used in high-temperature applications. This grade of nickel-copper alloy meets ASTM B165 and B725 specifications. Monel 400 Pipes and Tubes can be seamless, welded, ERW, or fabricated. The ASME SB165 Monel 400 Seamless Pipe meets ASTM, ASME, and API standards and is available in nominal bore sizes ranging from 15 inches to 150 inches.

What are Monel 400 Tubes?

Monel 400 Tubes is made of a material that can withstand temperatures below zero degrees Celsius. The material also has excellent mechanical properties. It is a 67% nickel alloy containing copper, iron, manganese, carbon, and silicon. Water from the sea that vaporizes often settles on structures near the sea in coastal regions. This vapor contains trace amounts of salt, which forms a deposition over time and easily corrodes the base metal. Alloy 400 ERW Tubes are also useful in environments where high temperatures produce steam.

Application of Monel 400 Pipes

The outer diameter of the pipes ranges from 6.35mm to 254mm, and the wall thickness ranges from 0.6mm to 20mm. They can be either round pipes or hydraulic Alloy 400 ERW pipes. The pipes are also available with plain, beveled, and threaded ends. Even though the ASTM B165 UNS N04400 material has a low annealed strength, it has excellent mechanical properties even at sub-zero temperatures. The Monel Pipe can withstand temperatures of up to 1000 degrees Fahrenheit. Controlling the amount of hot or cold working, as well as the selection of thermal treatments.

Properties of Monel 400 Tubes

It complies with ASTM B163 and B730 specifications, as well as ASTM, ASME, and API standards. The Monel 400 Welded Tubes have outer diameters ranging from 6mm to 50.8mm and wall thicknesses ranging from 0.7mm to 3mm. Monel 400 Pipes and Tubes are manufactured in a variety of ways, including Electric Resistance Welded tubes, seamless tubes, fabricated tubes, LSAW tubes, and ASTM B730 Monel 400 Welded Tubing. The addition of high nickel and 28% copper in the composition, as well as carbon, manganese, silicon, sulfur, and iron, results in a material with high strength. Monel 400 ERW Tubes have a minimum tensile strength of 550MPa and a minimum yield strength of 240MPa. The melting point is 1350°C, and the density is 8.8 grams per centimeter cube.
