OCTG Casing and Tubing Pipe.
OCTG (Oil Country Tubular Goods) are manufactured with care and high quality at our facilities in Baytown, TX/USA, and Gemlik, Bursa/Türkiye in line with the needs of our business partners globally.
Oil Country Tubular Goods (OCTG) are essential components in the energy sector, valued for their exceptional durability and reliability in demanding operational environments. These pipes are used to extract natural gas and oil from the ground and allow us to reach the resources we need in our daily lives.
OCTG pipes consist of two main classifications of products: casing and tubing. Tubing is the pipe that carries oil and gas from the ground to the surface. Casing is the pipe that protects the integrity of the wellbore and protects sensitive underground structures.
OCTG pipes are produced in Baytown and Gemlik facilities and delivered with the highest quality and different delivery options that can best meet the needs of our business partners. The raw material supply for OCTG pipe production utilizes high-toughness steel with a homogeneous material structure, ensuring consistent and precise mechanical properties for optimal performance. The raw material we use can be traced from the beginning of the process to the end.
