Bldg. 1410 - Repair Pipe Leak Repair

Project Title: Bldg. 1410 - Propane Pipe Leak Repairs Project Details/SOW: Small propane leaks detected near the threaded connections. Replace with socket weld to reduce the possibilities of future leaks. SOW - System will be isolated & secured at the main propane tanks. - All piping will be flared off after the point of isolation & purged with nitrogen before work begins. - Nitrogen purge during all welding operations. - Replace all piping on the north & south side of the building from the ground penetration up to the block valve. This pipe is currently all threaded, new piping will be socket welded to reduce possibilities of future leaks. - Repair or replace all leaking threaded fittings on the pump package with socket weld fings where possible. This will reduce the possibility of future leaks. - Repair all small fitting leaks by the vaporizers. - Replace the pipe from the vaporizers to the regulator manifold. Currently the pipe is threaded and leaking. The new pipe will be socket welded as much as possible from the red safety valve up to the regulator manifold. This will reduce the possibilities of future leaks. - This work will require 6 days of downtime. Trainer can be run cold during this time if needed.
