Oil and gas tubing requirements vary sharply by service point — surface gathering lines see different chloride and pressure conditions than downhole injection lines or hydraulic control lines exposed to H2S. TeCarve supplies seamless and welded stainless steel tube for exploration, gathering, hydraulic control and injection-well applications, with grade and wall thickness selected around the specific service conditions named in the project.

For sour-service or high-chloride environments, material selection and any applicable NACE MR0175 / ISO 15156 requirements should be confirmed and verified against the project specification before quotation — these are project-specific requirements rather than a blanket certification TeCarve holds independently of the order.
