Actual piping used in the project structure type
oil casing, in addition to the introduction, there are a variety of other structural forms of oil casing, to meet a variety of different conditions, in particular the special requirements of working conditions. In the engineering design or selection, the oil casing intensity level is higher, the higher the security, but also the greater cost of the project costs, will result in unnecessary waste.
From economic considerations, meet the design requirements while minimizing costs, the result is often easy to form a small selection of the many varieties appear on the whole oil casing, which is not conducive to the construction site materials management, regulation and design changes Replacement and other materials needed. Thus, the oil casing selection, should be integrated security and economy, minimize the oil casing varieties appropriate. In addition, the conditions of the construction site, construction level, oil casing of the procurement cycle and other factors, it may have caused the necessary attention in the selection of the oil casing. Under the circumstances, it should be considered to strengthen the pipe joint, the possibility of miter bend and small caliber tube bending field and the like.
