Oil Country Tubular Goods (OCTG)

Facing the challenges of developing deep and ultradeep reservoirs combined with increasingly sour, high pressure and temperature environments our range of OCTG products for drilling, production and injection tubing provides a solution. 

With API 5LC & API 5CRA quality approvals at the core of our processes combined with extensive Customer accreditations you can assured of our commitment to quality.  

Our integrated manufacturing processes ensure we have full control of our manufacturing routes and from which we define the optimal properties of corrosion resistance and mechanical properties from annealed condition to cold working using cold pilgering or cold drawing process.
