Net positive suction head, which is called in short form as NPSH and used in engineering pump designs and even in design engineering of various plants for location of pumps. What is NPSH? NPSH is a static head, which will be calculated from single datum or reference elevation (Normally datum elevation is considered as pump suction elevation as reference elevation) minus vapour pressure headRead More…
Oil Production – Oil and Gas Facilities Introduction This post gives some basic information for oil production facilities in Oil and Gas industry. When an oil-drilling rig strikes oil, the well is said to have “come in”. The drilling rig is removed, and the well is fitted with special equipment to allow the oil to be collected and processed in a controlled way. This collection process iRead More…

Surge Arrestors Surge arrestors are designed to control rapid velocity changes which may cause potentially dangerous pressure excursions. One method of accomplishing this is by using a vessel charged with inert gas and connected to the pipeline carrying the liquid. This vessel has the capability to convert the kinetic energy of the moving liquid into stored potential energy when a liquid overpreRead More…
