Four Steps of Progressive Pigging
Mitigate unnecessary losses and maximize pipeline throughput.
From capturing valuable natural gas liquids (NGLs) to filling and dewatering pipelines after hydrotesting, displacing liquids is central to optimizing production, performance, and profitability. Liquids displacement is also required during commissioning and decommissioning, nitrogen purging and inerting, and batching products in multi-product lines.
TDW provides a complete line of liquids displacement pigging solutions to help pipeline operators:
The company’s pigging products for liquids displacement include:
Best used for: liquids separation, recovery, and removal.
In general, multi-lipped conical cups are an effective choice for batching, dewatering, and displacement because they maintain their seal with the pipe wall even in out-of-round or dented pipe. Foam pigs are also commonly used for drying after initial water removal. Spherical pigs are preferred for removing liquids from natural gas lines.
TDW manufactures foam pigs, including the REDSKIN™ line, with an oversized diameter. The resulting tight fit helps ensure an effective seal, regardless of a pipeline’s wall thickness, making it an extremely effective batching tool.
Whether pipeline operators want to install cups for highly effective batching or blades and brushes for cleaning, OptionAll™ pigs can be assembled into multiple configurations for a variety of applications.
The ULTRA™ pig, a mandrel-type pig, is designed for highly effective batching. This pig can be used with TDW RealSeal® urethane cups with multi-lip sealing grooves, which further enhances its sealing capabilities.
Pipeline owners and operators can use the X-Pig® utility tool for nearly any pigging function, including batching, cleaning, gauging and liquids displacement, which significantly adds to this pig’s overall value.
