KOPPL uses the latest technology in coupon retention available. Hot Tapped safely with no interruption of service. When a Hot Tap is performe the double wired pilot drill retains the coupon and it is recovered when the Hot Tap is completed. This Checklist is a necessary component of the Hot Tap Plan required for any hot tapping and shall be attached to hot work certificate. The Checklist should be progressively completed during the planning and execution stages of the hot tap.
Exhibit provides a general schematic of a hot tapping procedure. The basic steps to perform a hot tap are: 1.
Connect the fitting on the existing pipeline by welding (steel), bolting (cast iron), or bonding (plastic) and install the valve. Install the hot tap machine through the permanent valve. Perform the hot tap by cutting the coupon. Regardless of the size, complexity, or location of a pipeline project, hot tapping and plugging (HTP) is the preferred method for performing maintenance, repairs, or modification work that requires making safe entry into a live, pressurized line.
This means that the pipe or vessel. How does Hot tapping machine work? What is tapping process? Hot tapping is an alternative procedure that makes a new pipeline connection while the pipeline remains in service, flowing natural gas under pressure.
Hot tapping is the technique of attaching a mechanical or welded branch fitting to piping or equipment in service, and creating an opening in that piping or equipment by drilling or cutting a portion of the piping or equipment within the attached fitting. Fitting and branch connections 4. Types of welding processes 2. Welding electrodes identifications 4. Typical hot tap procedure involves a fitting designed to contain system pressure, a valve to control the new con-nection and a hot tap drilling machine. Hot tapping identifies a procedure for installing a nozzle in the shell of a tank that is in service.
Remarks before made a Hot Tap.
A hot tap shall not be considered a routine procedure , but shall be used only when there is no practical alternative. Hot Taps shall be installed by trained and experienced crews. It should be noted that hot tapping of sour gas lines presents special health and metallurgical concerns and shall be done only to.
Introduction to the hot tapping procedure (with video ) Hot tapping , also known as pressure tapping , is the process of making connections to an existing pipeline, network or pressurised vessel without having to empty it beforehand.
