our products

Due to the ever-demanding needs of the energy industry, we provide high quality products per our customer’s specification requirements.

API Tubing/Casing/Pup Joints

Legacy Tubular (LT) stocks all grades of OCTG Tubing and Casing, including coupling stocks and mechanical tubes meeting API 5CT and API 5CRA requirements. Tubing is critical for well completion, carrying oil or gas from the reservoir to the surface. LT maintains strong inventory and relationships with tier-I mills globally, ensuring the ability to support projects of varying scopes. Threading options are supported by partnerships with thread license holders.
