* Canada's Brookfield and CPPIB, France's Engie may bid -paper
* China's CNPC shows interest in pipeline company -paper (Adds company comment)
RIO DE JANEIRO, Feb 25 (Reuters) - Brazil's state-led oil company Petrobras is expected to fetch as much as $6 billion from the sale of a natural gas pipeline unit in Brazil's industrialized southeast, the Valor Economico daily newspaper reported on Thursday.
Bids of between $5 billion and $6 billion for Nova Transportadora do Sudeste are expected by a Tuesday deadline from Canadian, French and Chinese companies, the paper said, without citing the source for its information.
Potential bidders include Canada's Brookfield Asset Management Inc, China National Petroleum Corp , and a joint venture between the Canadian Pension Plan Investment Board and France's Engie SA , Valor reported.
Petroleo Brasileiro SA, as the oil company is formally known, has plans to sell about $14 billion of assets this year in an attempt to cut its debt and maintain cash amid a plunge in world oil prices and a corruption scandal at the company.
Petrobras' estimated $130 billion of debt is the largest in the oil industry and one of the largest of any industrial company in the world.
A Brookfield press spokesman in Toronto declined to comment when contacted by Reuters. Engie's press office in Rio de Janeiro declined to comment. A Canadian Pension Plan Investment Board press official in Toronto declined to comment. CNPC officials did not immediately respond to an emailed request for comment.
