Pipe must penetrate through concrete wall and return inside the compressor room and must be properly mounted, supported, and sealed. Piping from cooler to auxiliary pump must be ¾-inch. Each outdoor cooler will have a dedicated ¾-inch pipe (2 separate gravity fed condensate lines) going back into the compressor room and into the auxiliary pump to pump condensate into the drain. Condensate lines that run outdoors must include heat tracer. Ensure equipment is tested for leaks, properly secured and sealed, and safe for operation. Quantity of (2) in-door 500-gallon wet tanks must be piped approximately 10-feet into quantity of (2) in-door desiccant dryers to remove remaining moisture from the compressed air. Piping from wet tank to desiccant dryer must be 3-inch reduced to 2-inch diameter using a reducer, include mount and support, include hand-operated ball valve at desiccant dryer inlet, include a separate 2-inch diameter pipeline with hand-operated ball valve to by-pass desiccant dryer. Confirm ball valves and reducers. Ensure pipe fitting and size are correct. Ensure equipment is tested for leaks, properly secured and sealed, and safe for operation. Quantity of (2) in-door desiccant dryers must be piped approximately 50-feet into quantity of (2) out-door 10,000-gallon air storage tanks. Desiccant dryers must include exhaust pipe vents. Existing vents are available on-site. Pipe must penetrate through concrete wall to go outside from compressor room and must be properly mounted, supported, and sealed. Air storage tanks are 6-feet apart and will supply air for wind tunnel operations. Piping from desiccant dryer to air storage tank must be 2-inch expanded to 3-inch diameter using an expander, include hand-operated ball valve at desiccant dryer outlet, include mount and support, include hand-operated ball valve at air storage tank inlet, include a separate 3-inch diameter pipeline with hand-operated ball valve to by-pass air storage tank. 3-inch diameter by-pass pipeline must join a 6-inch diameter pipeline coming from outlet of air storage tank which will join an existing airline. Confirm ball valve and expander. Ensure pipe fitting and size are correct. Ensure equipment is tested for leaks, properly secured and sealed, and safe for operation. Piping from in-door desiccant dryers to air storage tanks must be replaced and account for thermal expansion. Ensure pipe fitting and size are correct and must be properly mounted, supported, and sealed. Quantity of (2) out-door 10,000-gallon air storage tanks must be manifolded together and piped approximately 50-feet to return inside the compressor room where the pipe will join an existing airline (T-junction) with a 3-way diverter valve, or (2) butterfly valves, or (1) ball valve. Pipe must penetrate through concrete wall and return inside the compressor room and must be properly mounted, supported, and sealed. Piping from air storage tanks to existing airline must include 6-inch expanded to 10-inch diameter pipe using an expander. 10-inch diameter pipeline will be the existing air supply. Confirm diverter valve and expander. Ensure pipe fitting and size are correct. Ensure equipment is tested for leaks, properly secured and sealed, and safe for operation. Ensure redundant regulator is installed. Both compressors must be piped for oil cooling lines. The oil lines run from each compressor out to the remote oil coolers located outside rear of the facility in the same cooler system used to cool the compressed air. Each 500-gallon wet tank must be piped for condensate drainage. The piping will run from each wet tank to the oil/water separators (filter type - CRP Series 500 – 2000) then gravity drained to the auxiliary pump inside the compressor room then the condensate will be pumped into the drain. Piping from wet tanks to auxiliary pump is gravity fed utilizing a separator and approximately 25-feet. Pipe must be properly mounted, supported, and sealed. Confirm redundant regulator. Ensure pipe fitting and size are correct. Ensure proper mounting for separators during installation. Ensure equipment is tested for leaks, properly secured and sealed, and safe for operation. Quantity of (2) filters located near auxiliary pump in compressor room. Must have one filter for each wet tank. Must include quantity of (4) condensate drain clean out ball valves to be mounted at the bottom of (2) 10,000-gallon air storage tanks and (2) 500-gallon wet tanks. Piping will require 45° or 90° elbows and must include mounts and supports. Valves must be easily accessible outside air storage tank shielding. Air storage tanks and wet tanks must include redundant regulators for condensate drain. Must include 1.25-inch diameter NPT condensate drain clean out ball valves for the 10,000-gallon air storage tanks. Must include 1.00-inch diameter NPT condensate drain clean out ball valves for the 500-gallon wet tanks. The contractor shall also deliver and install the following: The 3-way valve, or (2) butterfly valves, or (1) ball valve will either: A) Direct air flow downstream towards the wind tunnel at 350 PSIG. B) Direct air flow towards the existing (8) 2000 cubic feet air storage tanks using a regulator to reduce the pressure from 350 PSIG to 150 PSIG. Ensure redundant regulator is installed. Add redundant regulators at 3-way intersection. Have pressure transducers before, after, and in between regulators to ensure regulators are performing adequately. If one regulator starts to fail, system sends a feedback alarm to the control and enter failsafe mode to avoid pressure going in undesired direction. Attempt to put valves and regulators at the lowest diameter section of piping with minimal impact on performance if possible. Include cost of capped off T-junction at some intersection along the 6-inch 350 PSI pipeline with an end cap before air enters the 3-way to divert the 350 PSI air down towards room 1 (location TBD in future).
