Our K55 tubing is specially designed for shallow and medium production tubing columns to achieve efficient fluid transfer and gas lift optimization at well depths ≤3500m and H₂S ≤50ppm. The core application is used in the production tubing Φ73mm in Changqing Surig tight gas field and gas lift system in Sahara oil field in Egypt. We also provide K55 with solution for Orinoco heavy oil development in Venezuela to ensure the integrity of tubing column in high temperature and high pressure environments.
