Product Detail

Our petroleum casing products strictly comply with API 5CT and ISO 11960 international standards, and we provide fully traceable factory test reports. Our products cover a wide range of sizes from 41/2“-185/8” OD, and can be machined to STC/LTC/BTC threaded end or flat end designs to meet the diverse needs of onshore, offshore, and unconventional oil and gas wells. For corrosive environments (e.g. H₂S/CO₂ gas fields), we provide 3PE/FBE coatings and other anti-corrosion solutions to significantly extend the life of the column.
