Expansion Joints
Expansion joints are used in piping systems to absorb thermal expansion where the use of expansion loops is undesirable or impractical. Expansion joints are available in slip, ball, metal bellows, and rubber bellows configurations. Slip-type expansion joints (Fig. A2.12a) have a sleeve that telescopes into the body. Leakage is controlled by packing located between the sleeve and the body. Leakage is minimal and can be near zero in many applications. A completely leak free sea

Strainers
Strainers are used in piping systems to protect equipment sensitive to dirt and other particles that may be carried by the fluid. During system start-up and flushing, strainers may be placed upstream of pumps to protect them from construction debris that may have been left in the pipe. Figure A2.9 depicts a typical start up strainer. Permanent strainers may be installed upstream of control valves, traps, and instruments to protect them from corrosion products that may become
