254 SMO Pipe Fittings

ANSI / ASME B16.9 ASTM A403 UNS S31254 Elbow / Stub End / End Cap manufacturer in Mumbai, India

Pipe fittings are versatile components that play a critical role in influencing the characteristics of the flow. 6Mo and 254 SMO are two grades of pipe fittings that are highly diverse and can be differentiated based on certain features.

  • 6Mo pipe fittings are designed with 6% molybdenum content, making them highly resistant to chloride-induced cracking and corrosive over 254 SMO pipe fittings.
  • The 6Mo alloy possesses more nickel content than standard 254 SMO fittings allowing them to exhibit superior mechanical properties.
  • 254 SMO fittings offer better weldability compared to their counterpart.
  • 6Mo fittings are designed with better stability and excellent formability during processing compared to 254 SMO pipe fittings.

What is the equivalent length of a 254 SMO 90 degree elbow?
The equivalent length of a 254 SMO 90 degree elbow can be defined as the length of a pipe of the same size as that of a fitting. This would give rise to the same pressure drop as that of a fitting. It is found that in a 90 degree elbow fitting that the equivalent length is larger in bigger fittings when divided by the inside diameter of the pipe. i.e. Le/D. E.g let us consider a 90 degree 254 SMO elbow having a value of Le/D to be 320. If it is installed with a schedule 40 pipe having an inside diameter of 52.5mm. The equivalent length will be 320 X 52.5= 16800mm. 

How do you measure ASTM A403 UNS S31254 long elbow radius?
ASTM A403 UNS S31254 long radius elbow has a radius of curvature, which is 1.5 times it, outer diameter. These elbows are split into two groups, which help in determining their radiuses. Elbows are characterized by the distance over which they change their direction in the system. The centerline of one end to the opposite face is commonly known as the center to face distance. For long radius elbows, the center to face distance is 1.1/2 X the nominal pipe size. To find the radius of a long radius elbow let us use this formula.
E.g. 90 degrees LR= 1.1/2 X 2(NPS) X 25.4 = 76.2mm.

How do you find the radius of a SMO 254 5D bend?
Pipe bends act as passages allowing the transfer of fluids or gases in the system. Some of these bends have short or long radius while being available in different bends. SMO 254 5D bend radius is five times the nominal diameter of the component. If a 10-inch diameter pipe is utilized alongside it, the centerline radius of the bend will be 50 inches. Pipe bending makes use of science and art to get it in the right shape. With today’s technology and advancements, pipe bending becomes highly precise and thorough.
