The design of our High Collapse and Sour Service grades is based on the development of carbon low alloy steels. The manufacturing process is strictly controlled from steelmaking through rolling and heat treatment.

GRADES TO WITHSTAND HIGH PRESSURES IN CORROSIVE ENVIRONMENTS
Tenaris has developed the High Collapse and Sour Service steel grades to meet the needs of oil and gas operations in environments characterized by a combination of high external pressure and the probability of corrosion cracking due to the presence of H2S.

We offer our High Collapse and Sour Service grades in a range of yield strengths from 80Ksi to 110Ksi.
