With the long influence of high temperature and stress, high temperature & high pressure steam pipeline of a thermal power plant will bring about creep damage or even tube explosion, which heavily threaten its safe operation. Therefore, the timely and accurate measurement of the pipeline creep is vital to the correct estimation of pipeline residual life and the prevention of various security ac...

using natural gas as a clean, plentiful and inexpensive source of energy in recent years has progressively increased in iran. pipelines are the most common system to transport natural gas from field to different regions of iran. these pipelines always pose risks to surrounding population and environments. the aim of this study was to assess the potential health, safety, and environment risk of ...

Abstract In order to recuperate the ultra-high purity xenon from PandaX-4T dark matter detector high-pressure gas cylinders in emergency or at end-of-run situation, a high speed recuperation system is designed and developed. This includes diaphragm pump, heat management system, main pipeline, reflux auxiliary pipeline automatic control system. The liquid vaporized by gaseous compressed 6 MPa fl...

A leaking water pipe bursting high pressure water jet in the soil will create slurry erosion which will eventually erode the adjacent natural gas pipe, thus causing its failure. The standard 300 mm safety distance used to place natural gas pipe away from water pipeline facilities needs to be reviewed to consider accidental damage and provide safety cushion to the natural gas pipe. This paper pr...

A model to predict fatigue crack growth of API pipeline steels in high pressure gaseous hydrogen has been developed and is presented elsewhere. The model currently has several parameters that must be calibrated for each pipeline steel of interest. This work provides a sensitivity analysis of the model parameters in order to provide (a) insight to the underlying mathematical and mechanistic aspe...

Ever demanding business and operating conditions have highlighted the need for significant improvements in the reliability of high duty mechanical seals. With platform operators under pressure to minimize deferred oil production due to equipment failure, there has been, in recent years, a much closer link between user and vendor to jointly develop solutions to satisfy the business requirements....

A computer program is developed to simulate steam flow in a pipeline as a part of “GeoSteamNet: a computer package for the simulation of steam flow in a geothermal power plant network”. The fluid movement is governed by the following basic principles: the conservation of mass, the linear momentum principle (Newton’s second law or Navier Stokes equations) and the first and second laws of thermod...
