.: MAINTENANCE ENGINEERING :.
We review new and existing piping systems and make recommendations so that they require minimum maintenance. Unfortunately, many piping systems have been designed as cheaply as possible so that the initial capital cost was minimized; however, now the maintenance cost is high, and system reliability is low. Poorly designed piping systems cause piping failures, vibrations, machine overloads, nozzle overstresses, foundation problems, etc.

MAINTENANCE / RELIABILITY ENGINEERING DETAILS
Plants today are expected to operate at higher production rates and less downtime than in the past, consequently, maintenance and reliability now play a greater role in plant operations. Many companies now focus on reliability issues such as monitoring and minimizing vibrations on rotating equipment, they also have improved maintenance departments, however, an important aspect of reliability that is overlooked, is piping system maintenance. Such as maintaining piping spring supports, restraints, low friction sliders, hydraulic snubbers, etc, so that the piping system does not break, cause flange leaks, or overload connected equipment. We review existing systems and make recommendations to improve their reliability. This is an important function and should be done on new systems as well as older systems. It is good to review and document newer systems to develop a baseline, or starting point, then to periodically review the system comparing observed differences to predict future performance.
