Flange Gaskets in piping are used to create a static seal between two stationary members of a mechanical assembly (the flanged joint) that maintains a leak-proof sealing during operation. The gasket material flows (interpose a semi-plastic material between the flange facings) into the imperfections...
joints are used to connect pipes together so that water can flow through the system. Without pipe joints, the piping system would not be able to function properly. This is because pipe joints provide support and stability to the piping system. They also allow for movement and expansion...
These strainers will be installed permanently in the piping system. Examples of permanent strainers are Y type strainers(Fig. 2) Basket Type strainers( Simplex & Duplex construction) (Fig. 3) and Y-Type Strainers This type of strainer got its name from the shape as it resembles the alpha...

How much more energy is required depends on the type and extent of the leak. For the 3 types of simulated leaks namely: orifice, circumferential and longitudinal slits with the same area of discharge, it is found that the excess pumping energy required for a circumferential crack in the pipe...
It is positioned between two seats that secure and support the ball. The ball is connected to the shaft at one end via a slot, while the other end remains free. When the valve is open, the shaft’s connection at the top of the ball keeps it from moving laterally....
