TRIS supply the world's best seamless coil tubes of up to 220lbs (100Kgs) and 7,477fts (2,279 mtrs). BA heat treated, our seamless coil tubes are excellent in internal surface quality, compared to other products. Long seamless coils, once used widely for petrochemical process, are being used more broadly in a variety of areas requiring higher reliability and critical applications like sub-sea, oil & gas, and shipbuilding industry.


Advantages of long seamless coil are;

  • Higher pressure & corrosion resistance than welded tubes.
  • Less fittings and orbital weldings, reducing defects and failures.
  • Economically feasible by saving the installation cost and time.

  • Making use of above strengths, our long seamless coils are used in severe application environment and industries requiring a higher level of reliability.
    All the products are performed and delivered after ECT as well as hydrostatic & ovality test satisfying ASTM standards. TRIS has the capacity to produce and supply 7,000 coils annually.
