pup joint flow line pipe with fig 1502 union In the process of crude oil and natural gas exploitation, oil pipes, as an important facility for oil and gas transmission after drilling, can transport crude oil and natural gas in oil and gas reservoirs to surface pipelines, which are widely used in oil and gas fields. Compared with foreign oilfields, the downhole environment of China's oilfields is more complex, and the problem of tubing corrosion is particularly prominent in China. According to...
5CT Standard Tubing or Casing Pup Joint in Gas and Oil Fields In view of the serious corrosion perforation at the tubing nipple in the oilfield, the digital camera was used to record the corrosion morphology of the inner and outer walls of the failed pipe section, and the vernier caliper was used to record the size of the failed pipe section. Use EDS, ICP and carbon sulfur analyzer to analyze the chemical element type and content of steel in the failed pipe section; The mechanical properties of...
API 5CT Perforated Pipe And Perforated Tubing Pup Joint Coiled Tubing (CT for short) is a kind of coiled synthetic tubing that can be wound on the drum according to the required length manufactured by the manufacturer. The outer diameter of the tubing is usually 0.75 "- 5", and the yield strength of the steel used ranges from 55000Psi to 120000Psi. At present, the longest oil pipe that can be wound by a single drum in commercial use is more than 9000 meters. Pup Joints are used to adjust the...

API Casing/Tubing/Coupling/Line Pipe The misalignment of the coupling will cause radial force, resulting in bending or deflection of the shaft during each rotation, thus affecting the fitting of the mechanical sealing surface inside the pump. The sealing surface is forced to open because the sealing spring is difficult to react to the bending of each shaft and higher vibration frequency in time. Rupture of the lubricant film between the sealing surfaces will cause wear and erosion of the...
