Treatment of oil tubing steel pipe 13crmo44 tube steel casing pipe
Oil casing is used to support the oil, gas shaft wall of the pipe to ensure that the drilling process and after the completion of the normal operation of the entire well. Each well according to the different drilling depth and geological conditions, to use several layers of casing. After the casing to take cement cementing, it is with the tubing, the drill pipe is different, can not be reused, are a one-time consumption of materials. Therefore, the consumption of casing accounted for more than 70% of all oil wells. The casing according to the user can be divided into the duct, surface casing, technical casing, and casing.
Steel casing pipe protects one or many of various types of utilities such as water mains, gas pipes, electrical power cables, fiber optic cables, etc.The utility lines that are run through the steel casing pipe are most commonly mounted and spaced within the steel casing pipe by using "casing spacers" that are made of various materials, including stainless steel or carbon steel and the more economical plastic versions.The ends of a steel casing pipe "run" are normally sealed with "casing end seals", which can be of the"pull-on" or"wrap-around" rubber varieties.Steel casing pipe is also used in the construction of deep foundations.
