| 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 fit over the pipe, crafted with precision to have an inside diameter slightly larger than the pipe's outside diameter. This thoughtful design allows the flange to glide over the pipe while maintaining a secure fit. Anchored with fillet welds at both the top and bottom, these flanges offer a snug and dependable connection. Categorized as either a ring or hub type, they provide versatile solutions for various applications.
Weld Neck Pipe Flanges
Weld neck pipe flanges are the epitome of strength and stability, seamlessly attaching to pipes through welding at the neck. This design facilitates stress transfer from the flange to the pipe, minimizing stress concentration at the hub's base. Ideal for high-pressure scenarios, these flanges are meticulously machined to match the pipe's internal diameter, ensuring precise and efficient flow control.
Blind Pipe Flanges
Blind pipe flanges serve as the ultimate barrier, sealing the end of piping systems or pressure vessel openings to halt flow. Perfect for pressure testing, they offer quick and easy access for maintenance within the line. Frequently employed in high-pressure situations, these flanges are a critical component in ensuring system integrity. Slip-on pipe flanges with hubs are available with specifications ranging from 1/2" to 96".
Threaded Pipe Flanges
Threaded pipe flanges, akin to slip-on flanges, feature tapered threads within their bore, suitable for pipes with external threading. Their distinct advantage lies in their ability to be attached without welding, making them ideal for small diameter, high-pressure applications. Slip-on pipe flanges with hubs are available with specifications from 1/2" to 24", catering to a wide range of operational needs.
Socket-weld Pipe Flanges
Socket-weld pipe flanges are engineered for smaller, high-pressure pipes, where the pipe is inserted into the socket end and secured with a fillet weld. This method ensures a smooth bore, optimizing the flow of liquids or gases. Slip-on pipe flanges with hubs, available in specifications from 1/2" to 24", provide a seamless solution for demanding environments.
