Types' Specification
Threaded
1. Used where welding would would be hazardous
2. Designed for low-pressure and non-cyclic applications
3. Bore is threaded to match pipe thread
4. Tapered to seal pipe and flanges
Slip-on
1. Not normally used in high-stress applications due to low hub and weld attachment
2. Silps over outside of pipe
3. Inside of flange welded at hub and end of pipe
Socket welding
1. For small-diameter chemical processes, hydraulic and stream distribution lines
2. Similar to slip-on flange
3. Counter bore matches pipe bore, allowing unrestricted flow
4. Counter bore from hub side fits pipe's outer diameter - can insert pipe in socket with fillet weld at hub
Lap joint
1. Used where bolt alignment or access for cleaning is required
2. Similar to slip-on flange when used with lap joint stub end
3. Radius at intersection of flange face and bore to match lap joint stub end
Blind
1. Used to close ends of piping
2. Has no bore
3.Permits access to sealed lines
Welding neck
1. Preferred for high-pressure, subzero or elevated temperature
2. Hub is tapered and bored to match pipe's inside diameter so flow is not restricted, preventing turbulence and reducing erosion
3. Easily radiographed and provides excellent stress distribution
