### Flange Types and Specifications
**Welding Neck Flange**
- Ideal for high-pressure, subzero, or elevated temperature applications.
- The hub is tapered and bored to match the pipe’s inner diameter, ensuring smooth flow and reducing turbulence and erosion.
- Easy to radiograph and provides excellent stress distribution.
**Slip-on Flange**
- Not typically used in high-stress applications due to limited hub and weld attachment.
- Slips over the outside of the pipe.
- The inside of the flange is welded at the hub and the end of the pipe.
**Lap Joint Flange**
- Used when bolt alignment or access for cleaning is needed.
- Similar to a slip-on flange when used with a lap joint stub end.
- Features a radius at the intersection of the flange face and bore to match the lap joint stub end.
**Threaded Flange**
- Used where welding may be hazardous.
- Designed for low-pressure and non-cyclic applications.
- The bore is threaded to match the pipe thread.
- Tapered to seal the pipe and flanges.
**Socket Welding Flange**
- Suitable for small-diameter chemical processes, hydraulic, and steam distribution lines.
- Similar to a slip-on flange.
- The counterbore matches the pipe bore, allowing unrestricted flow.
- The counterbore from the hub side fits the pipe's outer diameter, allowing the pipe to be inserted into the socket with a fillet weld at the hub.
**Blind Flange**
- Used to close the ends of piping.
- Has no bore.
- Allows access to sealed lines.
