Solids Build-up

Debris left behind during pipeline construction and solids that accumulate during pipeline operations can impact on the flow efficiency and impact capacity and throughout. In certain cases, such debris can also result in corrosion and damage to the pipeline and equipment.

TDW offers services to help Gas Distribution operators:

  • Maximize flow efficiency.
  • Improve operating capacity and throughput.
  • Avoid unplanned shutdowns.
  • Avoid costly maintenance, including equipment repair and replacement.
  • Enhance corrosion control.



A comprehensive pigging program will remove solids and sediments – including debris, sand, dirt, and corrosion-related contaminants such as black powder, scale, and salts – from Gas Distribution pipelines for better performance and profitability.
