What is UNS S31803 90 Degree Elbow
UNS S31803 90 degree elbow is one of pipe fittings and designed to change the direction in a pipe project. Commonly types of 90 degree elbow including long radius (LR) and short radius (SR) elbows.
Piping Elbows are very important pipe fitting which is used very frequently for changing direction in the piping, pipeline, and plumbing systems. They are essential pieces of fittings for routing pipes around obstacles or for creating a more efficient and organized pipe layout.
There are many different types of material of 90 degree elbow, such as carbon steel, alloy steel,low temperature, stainless steel and so on. Generally the UNS S31803 90 degree elbows are used in oil project, gas project, irrigation project and power engineering.
90 Degree Pipe Elbow Connection
Based on the connection method of 90 degree elbow, there are including three types:
Butt Weld 90 Degree Elbow
Socket Weld 90 Degree Elbow
Threaded 90 Degree Elbow
Material of UNS S31803
UNS S31803 material is called the standard duplex steel. UNS S31803 90 degree elbow is commonly used type of duplex due to the low cost and interchangeability between austenitic steel needs and duplex steel needs.
Chemical Composition
Fe | 63.75-71.92 |
Cr | 21.0-23.0 |
Ni | 4.50-6.50 |
Mo | 2.50-3.50 |
Mn | 2.0 |
Si | 1.0 |
N | 0.080-0.20 |
C | 0.030 |
P | 0.030 |
S | 0.020 |
Features
Duplex stainless steels are considered resistant to stress corrosion cracking, they are not as resistant to this form of attack as ferritic stainless steels. However, the corrosion resistance of the least resistant duplex stainless steels is much better than most commonly used grades of stainless steels 304 and 316.
Standard Reference
UNS S31803 90 degredd elbow dimensions&schedule are as below:
ASME/ANSI B16.9
ASME B16.28
MSS-SP-43
Production Process
UNS S31803 90 degree elbows are produced using optimal quality material offers a number of features like high strength and superb resistance to corrosion. they are also working hard enable alloys and can withstand the harsh environmental conditions. UNS S31803 is the austenitic ferritic chromium, iron and nickel allot and there is the addition of molybdenum in this grade.
They are offered in the sizes and shapes like concentric reducer, elbows, end caps, crosses, couplings, stub end, tees, and return bend. types offered are the forged fittings, threaded, etc. The customers get the fittings which are as per the standards set by the industry that means of national/ international standard.
Testing and inspection is the process which is given great importance while manufacturing these fittings and so the customers can check lab test report or third party report while they buy this product from the reliable stores. This will help them to determine that the fittings which they are receiving are of best quality or not.
The company pack the fittings in suitable material or packages which prevent the product from damage and dust. These fittings finally are exported to the customers in the best condition.
Inspection
Visual the surface of duplex stainless steel UNS S31803 90 degree elbow fittings.
Check the marking. Such as size, material code, grade, thickness, heat No.
Measure the diameter and thickness whether in tolerance.
Test the chemical properties of UNS S31803 90 degree elbow.
