LEWA packages for pigging technology and pig cleaning

Pigging technology is applied in the oil and gas industry to clean and maintain pipelines. Therefore, the pig which is equipped with cleaning or service equipment is pushed through the pipeline.

For these applications, LEWA produces customer-specific packages. In these packages LEWA plunger pumps are used providing benefits like high hydraulic power, easy maintenance and long service life. To fulfil all the customers’ requirements, LEWA offers many options for the package including explosion-proof design or numerous optional controls and monitoring units.

Solution

Advantages of using LEWA packages for pigging applications:

  • Packages with integrated LEWA plunger pumps​​​​​​​ according to API 674 with large hydraulic power capacities up to 720 kW
  • Discharge pressures up to 3,500 bar
  • Flow rates up to 210 m³/h
  • Safety valves according to ASME, API, and EN standards
  • Flexibility in selection of materials
  • Fast and economical maintenance of the plunger pump: free access to all wearing parts, no special tools needed
  • Long life cycle of the gear because of the integrated double helical gear which provides a uniform force distribution and prevents axial loads
  • Protection of the pump gear from low oil levels and overload by monitoring temperature and lube oil pressure
  • Multiple use: With corresponding design, the plunger pumps also can be used with other fluids or in other processes (e. g. methanol or glycol injection).
  • Complete package in explosion-proof design according to ATEX, also with diesel engines
  • Optional: numerous controls and monitoring units or application specific pulsation dampers

Background

Pigging applications and service tasks in oil and gas industry

“Pigging” is a process in which highly viscous fluids are conveyed out of pipelines. The pig is a cleaning device that is pumped through the pipeline under pressure. Thus, contaminations are conveyed out of the piping.

In the oil and gas industry, usually pipelines with large diameters are in use. There, the pigging technology is not only needed for cleaning tasks. Furthermore, pigs with on-board cameras, ultrasonic or measurement technology are needed to verify the corrosion status of the piping for example. Additionally, some pigs are simply used to physically separate different fluids flowing through the pipeline.

LEWA offers customized packages which are designed for these so-called service tasks in oil and gas industry.
