What is Incoloy 825 Pipe?

Incoloy 825 Pipe is an alloy which is made up of balanced high-level contents of Nickel-Iron-Chromium alloy along with Molybdenum, Copper and Titanium. This alloy 825 pipe is more similar to alloy 800 but is more prominent to provide corrosion resistance in aqueous environments.

It comprises 38-46% Nickel, 19-23% Chromium, 22% Iron, 0.06-1.2% Titanium, 2.5-3.5% Molybdenum ,1.5-3% Copper, 0.05 Carbon, 1% Manganese, 0.03% Sulphur, 0.5% Silica and 0.2 Aluminium. It not only provides corrosion resistance in normal environmental conditions, but also resists corrosion in oxidized environments.

What temperature can alloy 825 pipes withstand?

Incoloy alloy 825 hot finished pipe can withstand wide range of temperature, and is even approved for pressure vessel operation temperatures up to 525 ° C. Section I, II and III, which are the tools that used for checking the high-speed machine parameters to understand the mechanical and machine properties of this material need temperature of 538 ° C.

Above -540° C, brittle phases occur at 825 pipe, resulting in creep-rupture properties. Ideal temperature makes it suitable for welding purposes, where this material is readily weldable by GMAW, GTAW and SAW. For this purpose, the joint must be clean to avoid weld pool contamination.

What is the velocity of Inconel 825 pipe?

There is a way to calculate velocity of WNR 2.4858 clad pipe, which is known by the name Acoustic longitudinal Velocity.

There are two ways to calculate this velocity:

Technique 1: V = D/t In this, find a proper place with a known thickness (t), for example, flange.

Technique 2: V = 2 x thickness/delta T In this, place a probe on a well-known thickness area and then try changing the value of velocity, until the original value back to original thickness.

Here delta T is the transient time which is the time from initial Pauls to the first black wall or in other words, time taken from 1st black wall to 2nd black wall.

Is Incoloy 825 seamless pipe magnetic?

Incoloy 825 seamless pipe although comprises high contents of Chromium, Copper and Molybdenum, it is a nickel-based alloy which is non-magnetic in nature. The only main reason why it is a great resistant to corrosions in both oxidized or adequate harmful environments, being very prone and high resistant to sulphuric and phosphoric acids.

These non-magnetic pipes can withstand low cryogenic temperatures and moderately high temperatures above 1000° F. Microstructure of the material changes, when exposed to temperature above 1000° F. This impacts strength.

What is the use of 825 pipe?

In oil and gas industries, usage of pipe 825 is widely recommended and often used at a large scale. Other industries that demand this material comprises chemical processing equipment, exhaust systems, and generation of power in many power plants. Multiple industries are supplied with UNS N08825 Pipe for their applications by CRA.

Because of their longevity and high tensile strength, they can withstand extreme conditions to yield good output. It can operate in both hot and cool working situations. Though not cheap, but it promises a lot of features that is beneficial for most of the industrial applications.

Is UNS N08825 pipe corrosion resistant?

Containing high-level contents of Nickel, Chromium and Iron, 825 Incoloy pipe offers extensively good corrosion resistance in almost all environments, be it normal harmful corrosive, aqueous, cryogenic or oxidized environments. It also provides corrosion resistance from reducing acids, seawater and alkalis.

Nicrofer 4241 welded pipe is known to be most ideal in use, which also provide resistance from oxidized acids too. On the other hand, if we add Molybdenum, this material is then well-equipped to deal with chloride or chlorine which normally results in, pitting or crevice corrosions and even stress corrosion cracking.
