Common Welding Defects

What is welding defects? Before going to welding defects, we should understand what is welding? Welding is a process of fabrication. This joins different materials, mainly metals or non-metals like thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion. However such as brazing and soldering, are used with lower temperature techniques, which do nRead More…

Topographical Survey

What is topographical survey or topographical map? Any industrial plants or building and even when we are planning to build new house, we should know about the land details. Question is “why it is required?” Why not we can directly build the house or plant on open area. But unfortunately this is not the correct way. I will explain you why it is required, suppose you start building a constructiRead More…

NPSH (Net Positive Suction Head)

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

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 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…
