Collapsed pipe at ArcelorMittal Temirtau plant was faulty

"There were irregularities in the pipe's construction. When it was being erected in the 1960s, instead of refractory bricks the builders used a different material. As a result, the temperature difference failure occurred inside the tube. In addition, on the day of the accident there was strong wind" said the deputy head of the Emergency Department of Karaganda Oblast Vladimir Pfarger.

According to him, the Commission has worked out three versions. "As a result, we have come to this conclusion," said the deputy chief of Emergency Department.

He said that the pipe had been built 48 years ago. According to the documents 25 years after there was a commissioning for internal inspection of the pipe.

"The specialists examined externally other pipes of the plant. Such deviations from the project have not been identified", said V. Pfarger.
