DESCRIPTION

The Welding Greek Institute (WGI) offers the new learning program “Hot Taps for in Service Pipeline Connections Course” that highlight the added value that Hot Tapping and Plugging practices can offer to support engineers and technicians, who work in pipelines installation and maintenance.

 

Essentially, hot tapping is an alternative procedure that makes a new pipeline connection while the pipeline remains in service, glowing natural gas under pressure. This procedure involves attaching a branch connection and valve in the outside of an operating pipeline, and then cutting out the pipe-line wall within the branch and removing the wall section through the valve. Hot tapping avoids product loss, methane emissions and disruption of service to customers.

 

Hot tapping is usually performed when it is not feasible, or it is impractical, to take the equipment, Pipeline or Piping out of service, or to purge or clean it by conventional methods. This procedure is not a new practice, but recent innovations in design and technology mean that there is now more effective than before. Therefore, the payback period for utilizing such methods is often immediate.

 

Hot tapping is also referred as line tapping, pressure tapping, pressure cutting and side cutting. The process involves attaching branch connections and cutting holes into the operating pipeline without interruption of gas flow and with no release or loss of product. Hot taps permit new tie-ins to existing systems, the insertion of devices into the flow stream, permanent or temporary bypasses, and are the preparatory stage for line plugging with inflatable temporary balloon plugs (stoppels).

 

This training program covers a wide range of topics and gives candidates a good overall awareness of safely use the equipment and apply the modern techniques in successful hot tapping and plugging a pipeline. Consequently, by choosing this short course you could gain a competitive advantage in the marketplace, that would help you to find a job with better opportunities.

 

Swiss Approval International guarantees an accredited certification, giving the attenders the appropriate passport for the international market, ensuring with accuracy and independence the principles and rules that refer to hot tapping.
