Pipelines Services


Driving a PIG is the most common use of compressed air in the pipeline sector; and the professional products of PowerLink can offer the largest fleet of Air Compressorss in the industry. The Air Compressors is increasingly selected as it ensures no contamination to the pipe, following cleaning and other works.
Major demands for product:


Compressed air is used to drive a range of PIG (Pipeline Inspection Gauge) designs through pipelines.
Cleaning: A PIG can be a simple cylindrical bung with a sponge coating or made from metal and fitted scrapers. This type is most commonly used to clean pipes to remove debris, material sediment and corrosion.
Dewatering: After hydraulic pressure testing, a PIG is employed to remove all traces of water.
Coating: A further application is to use one or more PIG units to line or coat the interior of a pipe. This calls for precise speed of operation, with compressed air acting on one side of the PIG to drive it with a counter pressure on the other side to control its progress through the pipe. This task calls for expert compressor operation, something Powerlink is able to provide.

Challenges:

Normal pipeline cleaning is time-consuming and requires lots of energy and effort. It is very difficult to clean common instruments consistently, and sometimes this makes it impossible to meet the internal coating of pipelines due to the pressure control and high accuracy requirement.

Solution:

Screw Air Compressorss; A soundproof, rain-proof and dust-proof design, with low noise levels (the sound pressure of noise is 59 - 72 dBA@7m); the machine comes with compressor coolant.
In order to meet outdoor needs of complicated and harsh environments, optional parts can be utilised for extended periods under (-20℃) extreme cold or (50℃) extremely hot temperatures.
