A Seamless Elbow is a pipe fitting manufactured from seamless steel pipe,used to change the direction of pipelines by 45°,90°,180°or other angles.Without longitudinal or circumferential welds,it features uniform wall thickness,high structural strength,and excellent pressure resistance,making it widely used in medium‑to‑high pressure piping systems.
Features
Seamless structure:No welding seam,avoids leakage risks and weak points
High strength&pressure resistance:Suitable for high pressure,high temperature and medium impact conditions
Smooth inner wall:Reduces flow resistance and material buildup
Uniform wall thickness:Stable mechanical properties,less prone to deformation or cracking
Good corrosion resistance:Especially in stainless steel and alloy steel versions
Common Types
Angle:45°,90°,180°(return bend)
Radius:Long Radius(LR,R=1.5D),Short Radius(SR,R=1.0D)
Connection:Butt weld end(most common)
Materials
Carbon steel(A234 WPB,A106),alloy steel,stainless steel(304,316,316L),alloy steel,etc.
Standards
ASME B16.9,MSS SP-43,DIN 2605,EN 10253,JIS B2311
Applications
Oil&gas,petrochemical,power plants,chemical engineering,boiler systems,metallurgy,shipbuilding,and general industrial pipelines.
