Understanding what different smoke detectors are designed to do and how well their design and functions match up with the requirements and conditions of different facility environments goes a long way toward knowing where and when to use a certain type of detector.
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.
This article discusses the physical attributes of flexible fire sprinkler connections, and the financial/economic aspects of specifying flexible connections rather than hard-pipe armovers.
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.
