Reliable API Casing


Casing prevents the hole from caving in and seals of formations. Sovonex provides one of the largest selections of ERW pipe and seamless casing available, with pipes of all sizes, grades, and threads. Each casing joint is strictly manufactured to the latest edition of API 5CT or Russian GOST.


More Than Just Casing


We are experts of oilfield tubulars with years of experience in manufacturing.

Thanks to our extensive selection of casing pipes, you will most certainly find what you are looking for.


Production is based on lean production principles and just-in-time delivery, enabling us to significantly reduce delivery times. The improved manufacturing process is also a major reason for the constant high quality of Sovonex API casing.


Heat resistant casing (HR Casing)

We have developed a special casing that is resistant to high temperatures, combined with excellent pressure performance. Resistant to steam injection temperatures of 375 ℃ and pressures of 21MPa, Sovonex heat-resistant casing is ideally suited for use in thermal recovery wells. The HR casing greatly reduces the risk of corrosion and casing failure prevalent in thermal recovery operations.

Available in diameters from 4 1/2" to 7".


GOST Casing

The Russian GOST 632-80 standard extends API 5CT and includes special connections such as OTTG, OTTM, and TBG.

Certified by the Russian national standards body, Sovonex GOST casing has a strong competitive advantage in the Russian market as well as other countries of the Commonwealth of Independent States.
