The purpose of pressure-pipe tapping is to add bypasses, tees, and other construction techniques to pipelines without stopping production under pressure. First, a flange short section is welded to the pipeline, followed by a pressure-rated gate valve installed on the flange. The requirement is for the valve to be concentric and the bore diameter to be correct; after positioning, the valve
The purpose of pressure tapping is to add bypasses, tees, and other construction techniques to pipelines without halting production under pressure. Firstly, a flange reducer is welded onto the pipeline, followed by a pressure-rated gate valve on the flange, ensuring the valve is concentric and of the correct diameter. After positioning, the valve is fully opened, and the tapping drill is connected using bolts. The tapping is then performed according to the operational procedures. Once completed, the cutting tool is raised to the junction box, and the cut pipe material is removed. The valve is sealed, the drill removed, and the bypass connection is made.
Pressure Vessel Boring refers to a technique that involves machining a circular hole in a running pipeline under a sealed condition using mechanical cutting methods. It is primarily used in industries such as oil, chemicals, and pipelines. When it is necessary to install a branch pipeline on an operating pipeline, the pressure vessel boring technology can be employed to complete the task, ensuring that the normal transportation of the pipeline is not affected while guaranteeing a safe and environmentally friendly connection between the new and old pipelines.
