Maximum Shear Stress Theory
Maximum shear stress theory, also known as Tresca’s criterion, is a failure theory for ductile materials that states that a material will fail when the maximum shear stress exceeds a certain value, known as the shear yield strength. This theory…
Scaffolding Definition: Types, Parts, Design, Materials, and Hazards of Scaffolding
Scaffolding is a teaching method that involves providing students with a structure or framework for learning new information or skills. This structure can include things like examples, templates, or step-by-step instructions, and it is designed to help students understand and…
Types of Piping Drawings
Piping drawings, also known as piping plans or schematics, are technical drawings that show the layout and design of a piping system. They are used to guide the installation, maintenance, and repair of the system. These drawings typically include the…
Rockwell Hardness Test and Scale
The Rockwell hardness test is a widely used method for measuring the hardness of materials. It involves pressing a diamond or hard metal cone or ball into the surface of the material being tested and measuring the depth of the…
What is a Throttling Valve? | Definition, Applications, Working, Examples, Selection
A throttling valve is a device that regulates the flow rate of a fluid or gas in a pipe or duct by constricting or expanding the diameter of the passage through which the fluid or gas flows. It is also…
Overview of Pipe Coupling, its Types, Materials, Applications and Functions
A pipe coupling is a device used to connect two sections of pipe or tubing together. It can be made of a variety of materials, such as metal, plastic, or rubber, and can come in various forms, such as threaded,…
Thrust Block Design | Working of a Thrust Block in Pipelines
A thrust block is a structural component that is used to transmit the thrust force of a rotating shaft to the surrounding structure. It is typically used in machinery and equipment that has a high-thrust load, such as pumps, compressors,…
Hooke’s Law: Statement, Equation, Graph, Applications, Limitations.
Hooke’s Law states that the force (F) required to extend or compress a spring by some distance (x) is directly proportional to that distance. The constant of proportionality is known as the spring constant (k). The mathematical equation for Hooke’s…
Flange Bolt Torque Calculation and Pipe Flange Bolt Torque Chart
Flange bolt torque calculation is the process of determining the amount of torque that should be applied to the bolts of a flange connection in order to properly seal the joint and prevent leaks. This calculation takes into account several…
What is DN and PN Number for Pipes? Pipe Class Rating vs PN Numbers
DN (diameter nominal) and PN (pressure nominal) are two common terms used to describe pipes in the European and international piping industry. DN is a dimensionless term used to indicate the size of a pipe. It is based on the…
