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 |
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 |
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 |
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 |
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 |
Blind |
1, Used to close ends of piping |
2, Has no bore |
3, Permits access to sealed lines |
