Antwerp, Belgium, June 8, 2017: Cobra Group turns to Atlas Copco Rental to provide oil-injected diesel air compressors for pipelines cleaning during construction of gas network; and increases customer productivity by 80% thanks to wheel-mounted equipment.
Metrogas is a Chilean gas distributor which serves more than 527,000 customers in residential, commercial and industrial markets in the country's Santiago Metropolitan region and O'Higgins region (VI). The company owns and operates over 5,200km of natural gas pipelines.
When Metrogas started building a gas network along the country they contracted Cobra Group, a leading company of industrial infrastructures specialized in services related to distribution and commercialization of gas. Cobra has a 4-year contract nationwide including projects in the main regions as well as a future extension in the wide northern areas.
Based on their needs it was decided to select a mobile diesel driven model: the XAS 87-88. However, our equipment did not fully comply with some of the requirements such as:
Because they are wheel mounted our XAS compressors can easily move from one place to another, whereas previous equipment needed a truck-mounted crane since it did not have the suitable couplings for towing, which caused delays in in the work as well as additional transport costs.
The compressors are connected to the pipelines via hoses, also provided by Atlas Copco Rental Chile. Before installing the pipelines underground they are pressure cleaned with a pipeline-diameter sponge. In a second step, the air is used to dry out and remove all remaining impurities, enabling the proper circulation of the natural gas.
