Drains Vents and Purge Points

Pipeline drains, vents, and purge points all play a valuable role in safe pipeline operations for filling, purging, and draining pipeline systems. Often, it is necessary to add such connections to the pipeline for modification, operating, or other reasons. TDW provides products and equipment necessary for drain, vent, and purge point installations, as well as the expertise to prepare for and complete the work safely, without disrupting product flow.

TDW solutions enable Gathering operators to:

  • Make connections to a pipeline or pipeline system without shutdown.
  • Protect people, the environment, and communities throughout the installation.
  • Reduce the risk of costly project delays.

In the Gathering Pipeline market, where pipeline shutdown may not be an option, hot tapping technology provides operators safe, proven solutions for projects ranging from establishing purge points to placing a pig passage indicator or thermowell within a live line’s interior.

The tapping process calls for a high-pressure fitting , valve, and tapping machine – all working together to provide a safe and effective solution for creating an access point into a pipeline. This access point can then be used for inserting small probes, such as TDW PIG-SIG® pig passage indicators, or a multitude of other small sensors.

Whether operators are purchasing equipment to perform their own hot tapping and isolation jobs or turning to TDW to execute the service for them, they can rely on the TDW line of equipment and consumables. For example, the T-101 machine is the industry standard for small tapping projects, and when operators purchase a T-101 machine directly from TDW, they have the option of receiving training as part of the TDW Training Department’s LineMaster™ program. TDW offers the highest quality of training, which aligns with U.S. Department of Transportation operator requirements.

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.
