Pump Performance Curve A pump performance curve is a design analysis (or display) of a pump, how it performs in relation to changes in operating parameters such as pressure (head is derived from pressure) and flow. Operating parameter dependent factors are head, shut-off height, impeller diameter, efficiency, NPHSR, and power consumption. These terms are explained … Read more
Diffrent types of welding methods are used for welding stainless steel. We will discuss all the important welding methods of stainless steel. Let’s get brief idea about stainless steel. Stainless steel is a high carbon steel. It is widely used in the industrial sector due to its excellent corrosion resistance, elevated and cryogenic temperature properties. … Read more
A weld defect can be defined as an unacceptable defect during welding process. Unacceptable deviations in set technology and design called a weld defect. Weld defects can occur at any stage of the welding process,They are easily recognisable in the form of geometric errors. Such weld defects affects both inside and outside metal structures.Various codes … Read more
Introduction of Pipeline Welding: Joining of unifom pipes by welding process is known as pipeline welding. Diameter and material of all the pipes in a pipeline are same. Pipeline welding is a critical job and should be performed by skilled workers. Pipe welding and pipeline welding are two different things. Pipe welding refer to uniform … Read more
Definition of Mach Number: The velocity of an object in a medium divided by the sound velocity in that medium is called Mach Number. Mach Number is indicated by “M”. There is no dimension of Mach Number because it is the ratio of two velocity. Mach number (M) = [object velocity(u)] / [sound velocity(c)] Importance … Read more
Pressure relief valve is used to release extra pressure. This type of valve normally used in tanks and pipelines containing high pressure fluids. Its short form is PRV. Predefined pressure is set in the pressure relief valve. When pressure exceeds beyond defined pressure, PRV released extra pressure. When pressure goes down, PRV closes again. This … Read more
Slurry pump is a type of centrifugal pump that is used to pump slurries. Slurry is highly abrasive liquid which contain high concentration of solid particles. It is very difficult to pump slurries with the help of normal centrifugal pump. So, special type of slurry pump is used to pump slurries. In this write-up, I … Read more
Socket weld is a permanent pipe joining technique. It is used to join pipes and its componants. Socket weld is a very reliable welding technique due to high leakage integrity and structural strength. In this blog post we will discuss all the important things related to socket weld. What is a Socket Weld? Socket weld … Read more
