About Us

Oil casing is a large-diameter pipe material that serves to fix the walls or wellbore of oil and natural gas wells. The casing is inserted into the wellbore and fixed with cement to help separate the rock layers and prevent wellbore collapse, while ensuring the circulation of drilling mud for easy drilling and mining.

According to the strength of the steel itself, the casing can be divided into different steel grades. The steel grade used varies depending on the well condition and depth. In corrosive environments, the casing itself is also required to have corrosion resistance. In areas with complex geological conditions, casing is also required to have anti collapse performance.
