Sandwich valve hot tapping is a method of creating a branch connection on an existing pipeline without the need for a shutdown. It involves the use of a specialized valve known as a sandwich valve, which allows for the installation of a branch line while the pipeline remains in operation.

The sandwich valve is a unique type of valve that is designed to fit between two flanges on an existing pipeline. It consists of a body, a gate, and a sealing mechanism that allows for a safe and reliable branch connection. The gate is designed to open and close, allowing the flow of fluid through the branch line as needed.

The sandwich valve hot tapping process begins with the installation of a hot tap fitting on the pipeline. A drilling machine is used to create a hole in the pipeline, and the hot tap fitting is attached to the hole. Once the hot tap fitting is securely in place, the sandwich valve is inserted between the flanges, and the branch line is installed.

The sandwich valve hot tapping method is commonly used in pipeline applications where shutting down the pipeline is not feasible or cost-effective. It is also used in situations where a temporary or permanent branch line is required.

One of the significant advantages of sandwich valve hot tapping is that it allows for the installation of a branch line without disrupting the flow of fluid through the pipeline. This reduces downtime, increases productivity, and saves money.

The sandwich valve is also designed with safety in mind. The valve is manufactured to strict standards and undergoes rigorous testing to ensure that it can withstand high pressure and temperature. It also features a positive mechanical stop that prevents over-torqueing, ensuring that the valve is properly installed and secured.

In conclusion, sandwich valve hot tapping is a safe, reliable, and cost-effective method of creating a branch connection on an existing pipeline. It involves the use of a specialized valve that is designed to fit between two flanges on the pipeline. The process allows for the installation of a branch line without the need for a shutdown, reducing downtime and increasing productivity. The sandwich valve is designed with safety in mind and undergoes rigorous testing to ensure its reliability in pipeline operations.
