The use of new pup joints reduces the failure rate of oil pipe pup joints

Petroleum plastic casing is a pipeline material used for oil extraction and transportation. It has many unique characteristics and a wide range of applications. The following will introduce the characteristics and application scope of petroleum plastic casing.

The method of on-site compensation and control of oil pipe pup joints and oil pipe hangers has been studied, and the on-site application has achieved good results, effectively reducing oil pipe pup joint failure accidents and improving the quality management level of oil pipe pup joints. In the study of the failure mechanism of oil pipe pup joints, it was discovered for the first time that the eccentricity of the external threaded pipe end has a greater impact on the pup joint connection strength, which is of great value for optimizing the pup joint structure and improving the pup joint connection strength.
