Lateral Connection

Reliable lateral lines – pipeline segments that branch off the mainline or transmission line – play a critical role in pipeline integrity and functionality. That’s why the tie-in and commissioning of lateral connections requires extensive knowledge and experience

TDW offers a full suite of services, equipment, and consumables that allow the Gas Transmission market to:

  • Continue product flow while tie-in and commissioning take place.
  • Keep people, the environment, and communities safe throughout the installation project.
  • Keep lines in compliance with company, industry, and regulatory requirements.
  • Reduce the risk of costly project delays.

In the Gas Transmission market, where pipeline shutdown may not be an option, hot tapping and plugging (HT&P) technology allows operators to expand lines, make connections and tie-ins, launch new services, and upgrade capacity – all while their line is in service. TDW HT&P solutions protect operators’ revenue stream while minimizing risk and are available for a wide spectrum of pipelines, environments, and products. 

The HT&P process incorporates a high pressure pipeline fitting, valve, tapping machine, and isolation equipment – all working together to provide a safe and proven isolation solution. Once the area of pipeline that requires work has been safely isolated and evacuated, the line modification can be performed. 

The full suite of isolation solutions offered by TDW plays a critical role in this process. The TDW STOPPLE® Train isolation system, for example, uses double block and bleed technology to help increase efficiency and safety during pipeline modification. The system – which only requires a single pipeline tap – reduces costs associated with fittings, valves, welding, and inspection services. The bleed port affixed on the line ensures that any product bypassing the first seal is contained and evacuated through the bleed port, which creates a safe zone in high-consequence areas.

Because double block and bleed technology plays such a large role in protecting people, the environment, and communities, a number of regulators in Canada now require it for HT&P projects – and American regulators are moving in that direction.

Whether operators purchase equipment to perform their own HT&P jobs or turn to TDW to execute the service for them, they can rely on the broad line of equipment and consumables from TDW. The company engineers and manufactures nearly every component needed for an HT&P project, and TDW tapping and plugging machines are considered the industry standard.

TDW can also partner with operators before the work begins, providing consulting services to help them make optimum use of TDW products and services. TDW application engineers are recognized industry experts, ready to assist operators through each project phase – from start to finish.
