What is the difference between hard piping and soft piping in a process plant?

Hard piping in a process plant refers to pipelines that are rigid and made from materials such as metal or PVC. These pipes are typically used for high-pressure or high-temperature applications and provide structural support to the system.

On the other hand, soft piping, also known as flexible piping, is made from materials like rubber or plastic. Soft piping is more easily bendable and is often used for temporary or low-pressure applications where flexibility is required.

In summary, the main difference between hard piping and soft piping is the material composition and flexibility. Hard piping is rigid and durable, while soft piping is more flexible and adaptable to different needs in a process plant.
