Hot Tap /Line Stop Fittings
These fittings are used during hot tapping or line/flow stopping operations on live pipelines. F4 specializes in engineering, designing and manufacturing various pipeline fittings, including hot tap/line stop tees (both fabricated and forged types), welding and bolting types with closure flanges and plugs/flow-through guide bar plugs, hot tap branch nozzles with RF pads, gas bagging line stop nozzles with closure flanges and plugs, and 3-way split tees.
Our pipeline fittings are designed and manufactured to ensure that the integrity of the piping system is maintained. We adhere to ASME B31.1, ASME B31.4 and ASME B31.8 codes in the design of our fittings. We manufacture fittings in ANSI 150#, 300#, 600#, 900# and PN series up to 48 inches, using various materials such as carbon steel, alloy steel and mild steel. (Fittings above 48 inches can be supplied upon specific request/order).

Hot Tap / Line Stop Full Encirclement Split Tees
Hot Tap / Line Stop Full Encirclement Split Tees are essential fittings for hot tapping or line stopping operations. F4 supplies both fabricated and forged/extruded types of full encirclement split tees. These tees can be supplied with a flow-through guide bar for hot tapping operations, or with an L-O-R plug or cam lock plug for line stopping operations, depending on customer requirements.
Hot Tap / Line Stop 3-Way Tees are similar to full encirclement split tees but feature an additional branch connection. This provides multi-branch connections in hot tapping operations or allows for temporary/permanent bypasses in line stopping operations.
| Sizes | Pressure Rating |
|---|---|
| 2 Inch to 48 Inch (Above 48 Inch can be supplied against specific request/Order) | ANSI 150# | 300# | 600# & PN Series |
| (Higher Pressure Rating Available Upon Special Request) | |
Hot Tap / Line Stop Mechanical Tees
Hot Tap Mechanical Tee
Line Stop Mechanical Tee
These Hot Tap / Line Stop Mechanical Tees are similar in design and construction to full encirclement split tees, but instead of welding, these split tees are fastened to the mainline using fasteners on both longitudinal sides. These are generally recommended for low-pressure operations.
| Sizes | Pressure Rating |
|---|---|
| 2 Inch to 48 Inch (Above 48 Inch can be supplied against specific request/Order) | ANSI 150# & PN SERIES |
Hot Tapping Nozzle
Flanged Nozzle with RF Pad
Flanged Nozzle with RF Pad are used in hot tapping operations where the tapping size is smaller than the mainline size. These fittings are of fabricated type.
Flanged Nozzle
Flanged Nozzle are typically used in situations where the design pressure of the pipeline is relatively low. These fittings are of fabricated type.
Weld-O-Let Flange
Weld-O-Let Flange are employed for hot tapping when the tapping size is significantly smaller than the mainline size. These fittings are of fabricated type.
| Fittings | Sizes | Pressure Rating |
|---|---|---|
| Flanged Nozzle with RF Pad | 2 Inch to 48 Inch (Above 48 Inch can be supplied against specific request/Order) | ANSI 150# & PN SERIES |
| Flanged Nozzle | 2 Inch to 48 Inch (Above 48 Inch can be supplied against specific request/Order) | ANSI 150# & PN SERIES |
| Weld-O-Let Flange | 2 Inch to 48 Inch (Above 48 Inch can be supplied against specific request/Order) | ANSI 150# & PN SERIES |
Thread-O-Ring Fitting
Thread-O-Ring Fitting are specialized components essential for line stopple operations. They facilitate pressure balancing between the mainline and the line stop operation system. These fittings also enable the draining and venting of the product from the isolated section.
| Sizes | Pressure Rating |
|---|---|
| 2 Inch & 3 Inch | ANSI 150#, 300#, 600# & PN Series |
