Butt Welding Stainless Steel Pipe Elbow Fitting

Butt welding stainless steel pipe elbow fittings are essential components in piping systems where two pipes need to be joined at an angle. These fittings are designed to create a strong, permanent bond through a welding process, ensuring a leak-proof and durable connection.

Types of Butt Welding Stainless Steel Elbow Fittings

1. By Angle

  • 45º Elbow: Used to change the direction of the pipe by 45 degrees.
  • 90º Elbow: Used to change the direction of the pipe by 90 degrees.
  • 180º Elbow: Used to allow the pipe to make a complete U-turn.

2. By Radius

  • Long-Radius (LR) Elbow: The radius of curvature is 1.5 times the diameter of the pipe (R = 1.5D).
  • Short-Radius (SR) Elbow: The radius of curvature is equal to the diameter of the pipe (R = 1D).

3. By Size

  • Reducing (Reducer) Elbow: Connects pipes of different diameters.

Manufacturing Process

1. Mandrel Forming

  • Primarily used for seamless elbows.
  • Involves pushing a mandrel through the pipe to form the desired shape.

2. Ball Forming/Hot Forming

  • Typically used for 180º elbows.
  • The pipe is heated and shaped using a ball or another forming tool.

Surface Treatments

  • Aid Pickling: Removes scale and oxides from the surface.
  • Polishing: Achieves a smooth, shiny finish.
  • Shot Blasted: Surface treatment to clean and strengthen the metal.
  • Rolling Sand: Surface finishing process to enhance appearance and texture.

    • Nominal diameter: 32-48: ±3.05 mm
  • Inside Diameter: ±0.76 mm to ±4.83 mm depending on the nominal diameter.

  • Wall Thickness: Minimum wall thickness is 87.5% of the specified WT.

  • Center to End (45º/90º Elbows): ±1.52 mm to ±4.83 mm.

  • Center to Center (180º Elbows): ±6.35 mm to ±9.65 mm.

  • Back to Face (180º Elbows): ±6.35 mm.
