Hot tapping, also known as pressure tapping, is a technique for connecting to a pressurized system, such as a pipeline or pressure vessel, without stopping the tank or pipe from operating (either by cutting or drilling). This avoids costly and sometimes hazardous environmental issues while maintaining operations.

“Hot tapping” refers to the process of installing connections to pipes while they are still in service. In the context of welding, it is commonly used for any welding onto already-used equipment. Adding branches to an existing system or fixing parts that have been corroded or mechanically damaged are common uses for the hot tapping technique. There are obvious financial and environmental advantages to doing this welding without stopping a pipe’s flow and possibly releasing large volumes of greenhouse gases, such methane.

Safe hot tap welding techniques can be created by utilizing flow loops and computer heat flow modeling techniques. This approach involves matching and managing the live pipeline’s cooling capacity, which can be quantified.

Hot Tap pipeline stop Flanged fittings: These fittings are flange-style and fastened to the exterior of the pipeline. They have a hot tapping valve assembly and a pressure-tight seal that enable the hot tapping machine to be connected.

Hot Tap pipeline stop Tees Fittings: Although they are made to support the hot tapping operation, hot tapping tees resemble standard tees used in piping systems. They have a pressure-tight seal and a hot tapping valve assembly at the branch connection.

Hot Tap pipeline stop Clamp Fittings: These customized clamps provide a connection point for the hot tapping machine or other equipment while encircling the existing pipeline.

Hot Tap Pipeline stop Saddle Fittings : One kind of fitting that clamps onto the existing pipeline is called a hot tapping saddle. It offers a safe connection for the hot tapping operation with a branch connection that has a valve assembly and a pressure-tight seal.

Weld-On Hot Tap pipeline stop Fittings : By welding these fittings straight into the pipeline’s surface, a permanent connection point for hot tapping operations is created.

Compression Hot Tap pipeline stop Fittings : The design of compression fittings makes it simple to install and remove them without the need for welding. In order to guarantee a leak-free connection throughout the hot tapping procedure, they employ compression seals.

Full Encirclement Reinforcing Saddle fittings: In order to preserve the integrity of the pipeline, hot tapping fittings occasionally come with full encirclement reinforcing saddles that strengthen the region surrounding the hot tap hole.

The size and composition of the current pipeline, the temperature and pressure conditions, and the particular needs of the hot tapping operation are all important considerations when choosing hot tapping fittings. To protect the safety and integrity of the pipeline and the surrounding environment during the hot tapping process, it is also crucial to make sure that the fittings adhere to industry norms and regulations.

We have a large selection of fittings with diameters ranging from 2 inches to 48 inches. To provide dependable and sturdy connections, each fitting is carefully equipped with a welding neck flange of ANSI Class 150, 300, 600, or 900. We are prepared to handle any requirement, offering custom solutions to satisfy your needs, should your particular requirements necessitate greater diameters or higher pressure ratings.

In order to establish a branch connection on an existing pipeline while it is still under pressure, hot tap tees—also referred to as pressure tapping tees—are crucial parts of the hot tapping procedure. These t-shirts are appropriate for this crucial function because of a number of important features.

When pipeline maintenance or repair is required, Petrosan line stop hot tapping weld fittings are the best option. Oil, natural gas, and other distribution pipelines can all be safely stopped by our line stopping equipment. To help with line stop installation for pipeline maintenance, we provide our clients with individualized customer support.

Our fittings include outlets ranging from 2″ to 48″ and are extruded with Uni-Lock Flange closures that are rated to ANSI classes 150, 300, 600, or 900. They come in larger sizes and pressure ratings.

The ability to securely connect to a pressurized system by drilling or cutting while it is on stream and under pressure is known as “hot tapping” or “hot tap line stop weld fittings.”

Common connections include :

Hot tap line stope weld  fittings such as Split Tee, Reinforced Branch. Since the diameters of the main and branch pipes are the same, split tees are frequently employed.

Isolation valve, such as a ball valve or gate valve.
The cutter and housing are part of the hot tapping equipment.
Hot taps on pipelines and mains can be made with mechanical fittings as long as they are appropriate for the job and made for the operating pressure of the pipeline or main.
