What is fluid coupling? A fluid coupling or hydraulic coupling is a hydrodynamic or hydrokinetic equipment that can transmit power and torque with the help of liquid (hydraulic oil). It belongs to the category of flexible coupling power transmission. This is based on hydrodynamic torque transmission device. It is the assembly of pump impeller, casing […]
What is rigid coupling? Rigid coupling Rigid coupling is used only whenever the misalignment between equipment shafts is very less or no misalignment is present in the system. When the equipment is appropriate to carry the reactionary load produced from trying to flex rigid couplings. This type of coupling mostly prefers for vertical applications such
Butterfly valve (API 609) Butterfly valve is also called a quarter turn valve, this type of valve used for shutoff, regulating and starting the flow. The operation is either in open condition or fully closed of the disc in side body. In some applications it is also used as an alternative to a ball or
What is a globe valve? A globe valve is a linear motion valve and used for control, regulate, start or stop the flow inside the piping system of the fluid. The disk of the globe valve can be totally pulled out from the way of fluid flow and it has perpendicular to the flow motion.
What is the gate valve used for? Gate valve used for isolation of the piping system, also known as the isolation valve. Due to the working principle during the operation, it will either be in fully closed condition or in fully opened. The main benefit of gate valves in piping systems is to minimize frictional
Types of Valve Valves are mechanical devices that control the flow of fluids (liquids, gases, or slurries) by opening, closing, or partially obstructing passageways. There are various types of valves designed for different applications, and they are categorized based on their function, design, and the industry they serve. Additionally, valves are subject to various codes
Management of change (MOC) Management of change (MOC) is that any measures or minor changes in the process plant are called management of change. There are many types of management changes that occur in a plant, like changes in P&ID, changes in isometric drawing, changes in equipment design, changes in operating procedures, changes in inspection
Bearing The term bearing comes from the bear, a bearing is a component that supports load while permitting relative motion between two parts of the machine. Bearing is an important part of a machine that carries the load, reduces friction, and gives a smooth operation. The selection of bearings is based on the requirement of
Cavitation in the centrifugal pump Cavitation in centrifugal pump is the formation of bubbles, because the liquid suction pressure fall below its vapor pressure or any other reasons. There are many cases of cavitation in centrifugal pumps, these are discussed below. The formation of the bubble mostly happens in a pipe inside, equipment, valves, and
NPSH (Net positive suction head) What is NPSH? NPSH (net positive suction head) is the difference between suction pressure and lowest pressure inside the pump or system. By the use of the Bernoulli theorem, calculated if the suction pressure is greater than vapor pressure, then the risk of cavitation is negligible, but in other cases,
FMECA (failure mode effects and criticality analysis) The (FMECA) failure mode effects and critical analysis method is used to identify and prioritize failures that could occur in the processing system or particular equipment. It is a part of FMEA. With the help of failure mode effects and criticality analysis to identify what types of maintenance
What is a gasket? A gasket is a mechanical seal that is placed between two or more mating surfaces to prevent fluid or gas leakage. Gaskets can be made from a variety of materials, such as rubber, metal, cork, or paper, depending on the application requirements. They are designed to conform to the irregularities of
