Hot Tap / Line Stop Fittings

These fittings are used when Hot Tapping or Line / Flow Stopping Operations are executed on the live pipelines. F4 is Specialized in engineering, designing and manufacturing of various Pipeline Fittings, Such as Hot Tap / Line Stop Tee’s – both the Fabricated and Forged types, Welding and Bolting types – with Closure Flange and Plugs / Flow Through Guide bar plugs, Hot Tap Branch Nozzles with RF Pads, Gas Bagging Line Stop Nozzles with Closure Flange and Plugs, 3 – way Split Tee’s etc.

Our Pipeline fittings are designed and manufactured to ensure the integrity of the piping system is well maintained. We adopt ASME 31.1, ASME 31.4, ASME 31.8 codes in designing of our pipeline Fittings. We manufactured ANSI 150#, 300#, 600#, 900# and in PN Series up to 48 Inches with various types of Carbon Steel, Alloy Steel and Mild Steel. (Above 48 Inch can be supplied against specific request/Order)

Hot Tap / Line Stop Full Encirclement Split Tees is a fitting required for hot Tapping OR Line Stopple Operation. We Supply both fabricated & forged /extruded type of Full encirclement split tees.The Hot Tap tee’s could be supplied with flow through guide bar, similarly the Line Stop tee’s with L-O-R Plug or Cam Lock plug depending on the costumer requirement.

Hot Tap / Line Stop 3-Way Tees are similar to Hot Tap / Line Stop Full Encirclement Split Tee, with an additional branch connection that provided the multi branch connections in a hot tapping operation OR Temporary / Permanent bypass in Line Stopple Operation.

These Hot Tap / Line Stop Mechanical Tees are similar to Hot Tap / Line Stop Full Encirclement Split Tee in design and construction. However, Instead of welding these split tees are fitted to the mainline using fasteners on the both longitudinal sides of the split tee. These are generally recommended for low pressure operations.

Hot Tapping Nozzle

Flanged Nozzle with RF Pad

 

Flanged Nozzle with RF Pad are used in Hot Tapping Operation, where Hot Tapping Size is comparatively smaller to the main line size. These fittings are of fabricated type.

Flanged Nozzle

 

Flanged Nozzle are used in hot tapping operation, where the Hot Tapping size is comparatively smaller to mainline size and the Design pressure of pipelines is very less. These fittings are of fabricated type.

Weld-O-Let Flange

Weld-O-Let Flange are used for Hot Tapping operations where Hot Tapping size is much smaller in comparison to mainline size, but the design pressure of mainline is high.
