Don’t buy UNS N02201 threaded union or alloy 201 socket weld coupling if NDT test certificates are not provided by suppliers in Dubai, UAE
What is stress relieving UNS N02201 threaded fittings?
The method to relieve stress from the Nickel 201 threaded fittings is heating the weld and base material for a certain period at a specified temperature schedule.
A furnace, resistive heating equipment, or induction heating equipment can all be used to generate heat.
The temperature threshold must be below the weld’s lower transformation temperature or the point at which microstructure changes occur; it will prevent damage.
The heat is gradually dialed down stepwise after maintaining the temperature for the needed time to enable even cooling.
Refer to the weight chart, dimensions, pressure rating, and sizes for NCF 201 forged coupling and Ni 201 socket weld fittings.
In which temperature range we can use UNS N02201 threaded union?
Nickel 200 fittings are vulnerable to graphitization at temperatures above 600 degrees Fahrenheit. It may undermine the fittings’ structural integrity.
However, alloy 201 fittings can withstand temperatures up to 1230 degrees Fahrenheit. Since the alloy used to create these fittings has a carbon-regulated chemical composition, UNS N02201 threaded unions tend to resist graphitization.
As a result, these fittings are less susceptible to embrittlement. The main reason is the intergranular precipitates between 600° F and 1400° F.
In addition to being resistant to oxidizing situations, the alloy exhibits outstanding corrosion resistance in a variety of neutral as well as mildly reducing settings.

What is influence of temperature cycling on the creep properties of Ni 201 threaded elbow
Experts created a model determining the outcomes of 650°C creep tests on ASME SB564 UNS N02201 threaded bushing.
The creep failure criteria were based on standard specimens’ experimental and finite element analysis results.
The effects of the initial preload, stress relaxation, and the external tensile load on creep damage and life were clear when investigated.
According to the examination of bolt stress relaxation, bolt preload is significantly impacted by stress relaxation. With creep time, the preload drops to a predetermined value and almost stays constant.

Advantages and disadvantages of WNR 2.4068 socket weld fittings?
- The nickel alloy 201 has superior mechanical properties with incredible corrosion resistance and strength. Some of the advantages of Alloy 201 socket weld coupling are
- The ability to create a bevel end is not an issue with socket weld fittings.
- There is nothing wrong with fixing it. You can change the welding position of Ni 201 socket weld fittings to flat welding.
Socket weld fittings’ drawbacks are:
- The expansion space between the socket shoulder and the pipe should be 1.6mm, which is huge.
- Corrosion due to internal fractures and expansion gaps in the socket weld system is highly prevalent, making it inappropriate for radioactive or corrosive applications.
- They are not useful in the food business due to high hydrostatic pressure since they create crevices and gaps that might be challenging to clean and prevent full penetration.
Without ultrasonic test results, do not accept orders of JIS NW 2201 threaded boss/lateral tee and ASTM B564 alloy 201 socket weld 45/90 degree elbows.
Is JIS NW 2201 threaded bushing corrosion resistance?
Hydrofluoric acid and alkalis are only two of the numerous corrosive conditions in which nickel 201 threaded bushings exhibit exceptional resistance.
The alloy fittings function incredibly well in reducing environments but may also be employed in oxidizing environments since it forms a passive oxide coating. It is a kind of protection for the outstanding caustic resistance of Nickel 201 plates.
Due to its lower carbon content, the Nickel alloy 201 forged cross is preferred when temperatures exceed 600 degrees Fahrenheit.
