SLIP-ON
Slip-on flanges are manufactured with an inside diameter that is slightly bigger than the pipe’s outside diameter.
| Sizes | Class | Material |
|---|---|---|
| 1/2" to 106" | 150#, 300#, 600#, 900#, 1500#, 2500# | ASTM A105 |
BLIND
A Blind flange is round plate which has all of the relevant boltholes but no center hole, and because of this feature this flange is used to close off the ends of a piping systems.

| 1/2" to 106" | 150#, 300#, 600#, 900#, 1500#, 2500# | ASTM A105 |
WELDING NECK
A Weld-Neck flange can be differentiated from all other types of flange by their long tapered hub.
| Sizes | Class | Material |
|---|---|---|
| 1/2" to 106" | 150#, 300#, 600#, 900#, 1500#, 2500# | ASTM A105 |
LAP JOINT
Lap joint pipe flanges slide directly over the pipe and are most commonly used with stub end fittings.

|---|---|---|
| 1/2" to 106" | 150#, 300#, 600#, 900#, 1500#, 2500# | ASTM A105 |
SOCKET WELD
Socket weld pipe flanges are attached by inserting the pipe into the socket end and applying fillet weld around the top

|---|---|---|
| 1/2" to 106" | 150#, 300#, 600#, 900#, 1500#, 2500# | ASTM A105 |
ORIFICE
Orifice Flanges are widely used in conjunction with orifice meters for measuring the volumetric flow rate of liquids and gases through a pipe. Two orifice flanges a1re called an orifice flange union. Each flange comes with a pipe tap for measuring the pressure drop of the flow through an orifice plate. This makes separate orifice carrier or tapping in the pipe wall unnecessary. Orifice plates do not come with the flanges and are sized based on the requirements of the process. One/Two jack screws are used to spread the flanges apart in order to change the orifice plate.

| 1/2" to 106" | 150#, 300#, 600#, 900#, 1500#, 2500# | ASTM A105 |
Ring-Type Joint
A Ring Type Joint (RTJ) Flange is basically a machined metallic ring having a deep groove cut into its face.Metallic RTJ gaskets sit in the groove to seal the flange pair. When the connecting bolts of the RTJ flanges are tightened, the gasket is compressed and the flange pair creates a leak-proof tight seal. RTJ flanges, in general, have a raised face with the groove into the face of the flange,1 but the raised face doesn't contain the pressure similar to weld neck raised face flanges.

Spectacle Blind
Spectacle blind flanges are highly specialized pieces of equipment that can be used for a variety of industrial applications. They provide efficient sealing. Reliable performance and are designed to help facilitate inspection, repair and maintenance needs. Spectacle blinds, also known as spades or ring spacers. A Spectacle Blind Flange is a specialized piece of equipment that can be used in many industrial applications. It features a drilled hole and two gaskets on either side when assembled, the combination of these components effectively isolates objects while providing a secure and reliable seal. Typically, these flanges are composed of stainless steel or other durable materials.
