Keystone provided Phase II,III, and IV engineering and design services for a project to replace existingfeedstock piping. The project goal was to evaluate three different options for routingand supporting the new pipe runs. For each option, Keystone provided a totalinstalled cost estimate, total downtime, and future expansion needs.  

Saving considerable costs and providing minimal downtime, the option chosen included a new elevated modular pipe rack located in the tank dike area. The rack design included vertical loops doubling as pipe bridges to accommodate pipe stress due to high-temperature service and to allow for equipment traffic in the tank farm. The rack modules, ranging from 40’-56’ in length, were fully welded in the shop and galvanized with the piping installed, steam traced, and insulated before shipping to the facility. Each module was lifted in place with piping jumpers welded between modules.
