150LB Slip On Flange ASTM A182 F22 Forged Steel Flanges ASME B16.5

Slip On Flange ASME B16.5

Slip on flange, shorted as SO Flange, is designed to slip over the outside of pipe and fittings and connected with another flanges. It is easier to align than weld neck flanges. SO flange is ideal for low pressure applications and generally provided with raised face.

 Zizi is manufacturer and supplier of forged steel pipe fittings, we produce ASME B16.5 slip on flanges in different sizes and materials.

Slip On Flanges vs Weld Neck Flanges

The differences between them are focused on 

1. Welding forms: Weld neck flange can be radiographed but slip on flange can not.

2. Nominal pressures: Nominal pressure of Weld neck flange is 1-25 MPa, while slip on flange is 0.6-4 MPa. 

3. Connection Mode: Weld Neck flange is butt welded with pipes and slip on flange usually is fillet.

Forged Flange Manufacturer


  1. Our workers will do marking with name, pressure, size, seal, schedule, material and heat No..
  2. Use plastic foam to wrap A182 F22 slip on flanges after done anti-rust oil.
  3. Pun flanges into wooden cases or pallets.
  4. Stick case marking on the outside of wooden case for easy indentification.


  1. Visual the surface. Such as dents, die marks, porosity, undercuts.
  2. Check the marking. Such as type, size, material code, pressure, heat No.
  3. Measure the size. Such as outside and raised face diameter,thickness of flange.
