Providing equipment selection and pipe sizes that deliver adequate water flow to plumbing fixtures and equipment in tall buildings is an important design task of the plumbing design professional.
As the use of plastic piping (such as ABS, CPVC, PE and PVC) in construction gained popularity, considerable testing and research took place to address issues related to fire performance.
The term "process piping" generally refers to piping systems that convey chemicals under pressure or vacuum, but also is used to describe utility piping systems such as plant water, and certain drainage piping systems.
The intent in designing and installing sanitary drainage systems is to ensure they will function reliably, are neither undersized nor oversized, and are constructed from materials, fittings and connections whose quality is regulated by codes and standards.
