The surface oil casing pipe protects the drilling to avoid contamination by shallow water and gas layers and support the wellhead equipment.Usually the outer diameter is 114.3 mm to 508 mm



Technical oil casing pipe separates the pressure at different levels so that the drilling fluid can circulate normally and protect the production casing pipe. Also to install anti-burst devices, leak-proof devices and tail pipes in the well.


Oil casing pipe leads the oil from the reservoir layer below the surface. It is used to protect wells and stratify drilling mud.
