OCTG are used for onshore and offshore oil and gas upstream operations. 

SERCO provides the strict quality required for the harsh working conditions of casing within the wellbore and the resistance to mechanical stress for tubing in production operations. 

We have 15 years of uninterrupted experience machining OCTG.  SERCO provides a full range of welded or seamless high quality casing and tubing, threaded with all API and premium connections.

SERCO offers conventional API grades up to Q125 (PSL-3) and certain proprietary high strength, high collapse, sour service and low temperature grades.

We also offer High Chrome grades of OCTG.
