Combustion mechanism of oxygen transferring piping is briefly described,the reason of combustion caused ans its prtecrive measutes are anslyzed ,and appropriate design code is also presentd

Numerical modeling of oil pipeline bending caused by migrating pingos in the permafrost on the northern Qinghai-Tibet Plateau;

A new method of synchronized design for oil pipeline and thermal insulation layer;

Design and implementation of the oil pipelines leak detection system based on wireless local area network;

Stability of pipe conveying fluid under axial load;

Research on natural frequency of pinned-pinned pipe conveying fluid;

Based on the stress anylysis of element,the vibration differential equation of the pipe conveying fluid on elastic foundations is derived,the mode and the nature frequency of the pipe are calculaed by variable-separating method and numerical method.

Research on characteristics of municipal sewage sludge and its pipeline transportation technology;

Experimental study on wax deposition in pipeline transportation of highly viscous crude oi1;

Experimental study on pressure loss feature of coal slurry pipeline transportation

Synchronization Phenomenon in Process of Water Hammer in Long Distance Pipelines;

Laser welding technology of long distance pipeline;

Numerical simulation of leakage and dispersion of acid gas in gathering pipeline;

In the case of small leakage or small size perforation of gathering pipeline, field patching approach is often adopted in doing rush repair.

In view of the complexity and uncertainty of the factors contributing to the gathering pipeline corrosion and the difficulty of predicting the remaining service life of corroded pipe,two methods ,the probabilistic statistics and artificial nerve network, are compared and studied to predict the remaining life of in-service corroded pipe.
