A FLEXIBLE PRESSURE-CONTAINING COMPONENT OF A PIPING SYSTEM WHICH IS DESIGNED TO ABSORB THERMAL MOVEMENT.
For fixed orifice double regulating valves, a minimum of 5 pipe diameters of straight pipe (without intrusion) should be installed upstream of the orifice plate, and a minimum of 2 pipe diameters of straight pipe are required downstream of the valve
Strainers
- If the application requires that the system has to run continuously and cannot be shut down, then the only real choice is a duplex basket strainer.
- If a vertical installation is planned, a Y-Strainer is the one that will work. Y-Strainers can be installed either vertically or horizontally. A basket strainer must be installed horizontally.
Valve selection according to (Function, Pressure drop, Work temperature, Closing time, Type of joint, Seat tightness, Type of seat, Type of medium, Materials, Design
& operating condition)
Strainers used to protect equipment sensitive from dirt or other particles carried by fluid
Expansion joint used to absorb thermal expansion if the use of expansion loops is undesirable or impractical
