How do you fit an Incoloy 825 butt weld Fittings with a pipe?
Buttweld fittings in the Incoloy 825 range are amongst the strongest and versatile types of fittings. These fittings can be easily connected to a pipe as they possess beveled ends as per directives set by ASME B16.25. These ends allow the modules to create a full penetration weld without the need for any extra penetration or preparation. The fittings are welded following butt-weld procedures where they are placed over the components and welded in place. The welded connections in this range offer a robust and high-strength connection. These fittings are available in bigger and stronger sizes compared to other grades of fittings.
Can you weld Alloy 825 threaded fittings?
Alloy 825 threaded fittings are components designed with a concentration of chromium, nickel, and iron coupled with additions of molybdenum, titanium, and copper. Threaded fittings in this range have threads, which correspond to that of the piping module. This enables them to be easily affixed to the thread on the subsequent piping component. The connection securely seals the components; however, in certain applications, these fittings can be easily welded in place. But it is not advised to weld the component as the already sealed threaded fittings may suffer a thermal expansion due to weld heating causing a crack or dent in the line.
What is the difference between ASTM B366 UNS N08825 SR 45 elbow and LR 45 elbow?
Elbows are versatile pipe fittings that influence the characteristics of the flow by redirecting them from different angles. These elbows are designed in different directions as short or long radius elbows. Both can be differentiated based on certain features.
- An LR elbow is an outer diameter of a tube whose radius of curvature is equal to 1.5 times its diameter. An SR elbow is a component whose radius of curvature is equal to the outer diameter of the tube.
- A 45 SR elbow will give a pipe a sharper turn-in comparison to an LR 45 elbow.
- LR elbows create lower pressure drop compared to SR elbows.
- SR elbows are cost-effective and preferred in applications where there is compact space available over LR elbows.
