As a widely used tube in oil industry, API Spec 5ct M65 Casing Tube is mainly used for drilling the oil and gas wells and transporting oil and gas. It includes oil drill pipe, oil casing pipe, and oil pumping pipe. Oil drill pipe is mainly used to connect drill collars and drill bits and transmit drilling power. Petroleum casing is mainly used to support the well wall during and after drilling to ensure the progress of the drilling process and the normal operation of the entire well after completion. The pumping pipe mainly transports the oil and gas at the bottom of the oil well to the ground.
