Product Overview
Our H₂S resistant coiled tubing downhole tools are specially engineered for sour oil and gas well environments containing hydrogen sulfide and carbon dioxide. The entire tool assembly including connectors, jars, accelerators, centralizers and other BHA components is manufactured from NACE MR0175 / ISO 15156 compliant materials with strict hardness control and heat treatment processes to eliminate sulfide stress cracking (SSC) and hydrogen induced cracking (HIC) risks. Each tool undergoes dedicated H₂S service material verification testing including hardness testing, PMI (Positive Material Identification) analysis and third-party witnessed material certification. The product range covers all standard coiled tubing downhole tool categories available in full sour service material grades, ensuring reliable long-term operation in the most corrosive downhole environments.
