Choose the pipe's size, weight and grade to compare the connections.

• Critical Service

  For mild CO2 environment, provides a cost effective alternative to carbon steel for sweet corrosion, where CRA is not economically justified.
  Relevant Grades: TN 55CS, TN 70CS, TN 75CS.

• Mild Sour

  API steel grades with improved resistance to SSC.
  Relevant Grades: TN 80S, TN 90S,TN 95S.

• Sour Service

  Higher resistance to Sulphide Stress Corrosion Cracking.
  Relevant Grades: TN 80SS, TN 90SS,TN 95SS, TN 100SS, TN 110SS,TN 125SS..

• High Collapse

  Designed for wells where high external pressures are anticipated, and collapse pressures higher that API values are required.

  Relevant Grades: TN 80HC, TN 95HC, TN 110HC.

• High Collapse & Sour Service

  Designed for SS wells where high external pressures are anticipated, and collapse pressures higher than API values are required.

  Relevant Grades: TN 80HS, TN 95HS, TN 100HS, TN 110HS, TN 125HS..

• Improved Collapse

  IC grades are API steel grades with improved performance - an excellent cost-benefit solution for less severe applications.

  Relevant Grades: L80-IC, T95-IC, P110-IC, Q125-IC.

• Deep Well

  Where high strength with good ductility and fracture toughness are required.

  Relevant Grades: TN 135DW, TN 140DW, TN 150DW.

• Thermal

  Designed for the production of high density oil under severe thermal service wells.

  Relevant Grades: TN 55TH, TN 80TH.
