10-3/4'' Casing Pipe

Oil wells for oil wells are mainly used for petroleum tubing connection and various fittings connected with petroleum oil pipes. It is a kind of sealing filler (such as hemp, yarn, asbestos fiber, rubber, etc.) that does not need to be coated. The thread sealant achieves a sealed conical thread. When the inner and outer threads are combined with each other, the centering and guiding functions are good, the assembly and disassembly are convenient, the large axial force can be withstood, the interchangeability is good, the service life is long, and the utility model can be repeatedly used repeatedly. Due to these characteristics, in the petroleum industry, the amount is large and the use is very wide, especially the reliability of the water pressure seal is more important in the use.
