| 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 |
| Other flanges |

Slip-on pipe flanges elegantly slide over the pipe, showcasing design precision. These flanges possess an internal diameter slightly larger than the pipe's external diameter, facilitating a snug yet accommodating fit. Secured with a fillet weld at both the top and bottom, slip-on flanges promise steadfast attachment. They are meticulously categorized as either ring or hub, each serving its unique purpose.
Weld neck pipe flanges
Weld neck pipe flanges form a robust connection by welding the pipe directly to the flange neck, allowing stress to transfer seamlessly to the pipe itself. This design minimizes stress concentration at the hub's base, making it ideal for high-pressure scenarios. The inside diameter skillfully matches the pipe's, ensuring a harmonious fit and flawless operation.
Blind pipe flanges
Blind pipe flanges are expertly designed to seal off the ends of piping systems or pressure vessel apertures, effectively halting flow. Commonly used in pressure testing liquid or gas flow, they provide convenient access for internal maintenance tasks. Their role in high-pressure applications is indispensable, with specifications ranging from 1/2" to 96".
Threaded pipe flanges
Threaded pipe flanges, akin to slip-on flanges, feature bore with tapered threads for seamless attachment to externally threaded pipes without welding. Perfect for small diameter, high-pressure demands, these flanges are available with specifications from 1/2" to 24", balancing convenience with high performance.
Socket-weld pipe flanges
Socket-weld pipe flanges are the choice for smaller, high-pressure pipes, employing a method where the pipe is inserted into the socket end, followed by a fillet weld on top. This results in a smooth bore, optimizing fluid or gas flow. Specifications for these versatile flanges also range from 1/2" to 24".
