E235 CASING TUBING for UAE Client

Casings are steel pipes that support the walls of oil and gas wells. Each well uses several layers of casing according to different drilling depths and geological conditions. Cement is used to cement the well after the casing is run down. It is different from tubing and drill pipe and cannot be reused. It is a one-time consumable material. Therefore, casing consumption accounts for more than 70% of all oil well pipes. Casings can be divided into pipes, surface casings, technical casings and oil casings according to their usage.

E235 is a common material for seamless pipes for hydraulic cylinders made of high-quality cold drawn pipes according to the specifications of en10305-1, 10305-2, EN 10305-3, EN 10305-4, and EN 10305-5 series, with a wide range of sizes. In addition to seamless cold drawn tubes, welded cold drawn tubes are also used for cylinders with smooth surfaces.
