There are three basic types of pipeline systems:
- Direct system
- Ring main system
- Free flow system.
Direct line system
Advantage:
- Quick loading & discharging.
- Short pipe line.
- Less bend.
- Less loss of pressure due to pipe line friction.
- Direct line to provide better suction.
- Time of washing the line is short.
- System is cheaper than the other system.
- Leak is minimized.
- Easy to operate so less training is required.
- It is easy to separate each cargo.
Disadvantage:
- In case of leaking the control of leakage is difficult.
- This system is very inflexible.
