Statement of Work
9m Low Speed Wind Tunnel Heat Exchanger and Piping Repairs.
NRC Project Number: Aerospace 46-IMC0119 ASPM 3817
SOW Number:
Version: 7
Prepared By: Xxx Xxxxxx
Telephone: (000) 000-0000 Facsimile:
1.0 Background and Purpose
The National Research Council’s 9m Wind Tunnel requires extensive repairs to a large bank of heat exchangers located within the settling chamber area of the wind tunnel (see Figures #1-#5).
For the past ten years or more, this system of heat exchangers has been operated in the summer months using treated water, and drained for the duration of the winter. The system is no longer operational due to excessive leaks. The leaks have been caused mostly by standing water that has frozen during the winter and broken a few of the tubes in some of the heat exchangers. This problem has been made worse by the amount of rust buildup in the heat exchanger tubes.
The heat exchanger system is comprised of five separate vertical columns of heat exchangers, only the center three columns are being repaired at this time. There are a total of 42 individual heat exchangers (coils), 38 of which are of common construction, 4 of which are smaller units of a different design.
2.0 Schedule
2.1 The contractor shall complete all work defined in this statement of work on or before August 30, 2013.
3.0 Mandatory Qualifications
3.1 As a mandatory bidding requirement the Contractor (or the subcontractor that will be responsible for the piping fitting /welding/repair aspects of this project) must be holders of a valid Certificate of Authorization, issued by the TSSA, for the fabrication and assembly of process piping in accordance with ASME B31.3 Process Piping Code.
4.0 Scope of Work and Supply
4.1 Materials Supply
All construction materials will be provided to the contractor by the NRC except for the following:
• All fabrication consumables such as for welding, grinding, steelwork and painting.
• Paint.
• Gaskets for the heat exchangers and piping.
4.2 Heat Exchanger Disassembly
4.2.1 The contractor shall remove (cut away) the horizontal sections (expansion loops) of the supply and return piping immediately adjacent to the heat exchanger manifolds. In many cases, there are no flanges between the supply piping and the heat exchanger manifolds. Clearances are tight, and in many cases, plasma cutting is assumed to be the most effective cutting process. The center column consists of seven supplies, seven drains, and seven 180o elbow assemblies (heat exchanger couplers). See Figure #5. The left and right columns have a similar number of piping connections. This totals to 65 short piping assemblies to remove.
4.2.2 The contractor shall remove the piping manifolds from the heat exchangers. There are approximately 40 bolts in each manifold, and 42 manifolds to remove. The heat exchanger end caps have already been removed.
4.3 Heat Exchanger Tube Cleaning
4.3.1 The contractor shall remove all debris from the heat exchanger tubes. Each heat exchanger has approximately 39 tubes, 15 feet long each. There are 42 heat exchangers.
4.4 Heat Exchanger Weep Holes
4.4.1 Each heat exchanger coil has a 3/8” diameter internal weep (drainage) hole that is easily accessible when the manifold has been removed. Some of these weep holes have likely become plugged due to rust build-up. The contractor shall ensure that all of the weep holes are open. See Figure #14.
4.5 Heat Exchanger Manifold Cleaning, Repairs, Adapters and Re-assembly
4.5.1 The manifolds are made from plate steel with 3.5” diameter pipe welded to them as outlets. The contractor shall clean each manifold (remove excessive rust build up and old gasket) as needed to ensure a leak-free and reliable gasket contact surface.
4.5.2 The contractor shall clean the heat exchanger as needed to ensure a leak-free and reliable gasket contact surface.
4.5.3 The contractor shall modify the manifold outlets as per Drawing 46- IMC0119-004. There are 38 manifolds to modify as shown, and another 4 to modify similarly using 2.5” pipe. Also see Figure #7.
4.5.4 Some of the manifolds have excessive local corrosion around the outlet pipes and drain fittings (see Figure #6). The contractor shall repair these areas by welding build-up as needed to restore the manifold’s original thickness in the affected areas.
4.5.5 The contractor shall supply and install new gaskets for all heat exchanger manifolds. The gaskets shall be cut from 1/16” thick EPDM rubber such as Garlock 8314.
4.5.6 The contractor shall re-install all manifolds and ensure that the fasteners have been properly torque-tightened as follows:
• Outlet Manifolds: 7/16” UNC bolts shall be tightened to 40 ft-lb.
• A second round of torque-tightening shall be required 24 hours or more after the first tightening to ensure the gaskets are fully set.
4.6 Heat Exchanger End Cap Cleaning and Installation
4.6.1 The contractor shall clean each of the heat exchanger end caps as needed to ensure a leak-free and reliable gasket contact surface.
4.6.2 The contractor shall clean the heat exchanger as needed to ensure a leak-free and reliable gasket contact surface.
4.6.3 The contractor shall supply and install new gaskets for all of the end caps. The gaskets shall be cut from 1/16” thick EPDM rubber such as Garlock 8314.
4.6.4 The contractor shall re-install all end-caps and ensure that the fasteners have been properly torque-tightened as follows:
• End caps: 3/8” UNC bolts shall be tightened to 25 ft-lb.
• A second round of torque-tightening shall be required 24 hours or more after the first tightening to ensure the gaskets are fully set.
4.7 New Heat Exchanger Supply Piping (Expansion Loop Piping)
4.7.1 The original 3.5” supply expansion loops shall be replaced with new 3” Schedule 40 carbon steel pipe. The new expansion loop will connect to the heat exchanger and the existing supply pipe using grooved pipe fittings and welded-on adapters. Drawing 46-IMC0119-001 shows the new expansion loop pipe assembly to be fabricated and installed. There are 16 locations where the assembly shown on Drawing 46-IMC0119-001 is required, and another 7 locations where similar supply piping assemblies shall be completely field-fit between existing piping and the heat exchanger manifolds. The lower-most heat exchanger in the center column will not be installed while the contractor is on site, therefore the contractor is not required to complete the supply piping for this heat one heat exchanger (to be completed by NRC).
4.8 New Heat Exchanger Drain Piping (Expansion Loop Piping)
4.8.1 The original 3.5” drain expansion loops shall be replaced with new 3” Schedule 40 carbon steel pipe. In addition, an isolation valve will be installed in each of these expansion loops. The valves are 3” diameter butterfly valves designed to be installed using grooved (Victaulic style) fittings. The new expansion loop will connect to the heat exchanger and the existing 8” drain pipe using grooved pipe fittings and welded-on adapters. Drawing 46-IMC0119-003 shows the new expansion loop pipe assembly to be fabricated and installed. There are 17 locations where the assembly shown on Drawing 46-IMC0119-003 is required, and another 6 locations where similar supply piping assemblies shall be completely field-fit between existing piping and the heat exchanger manifolds.
4.9 New Heat Exchanger Coupling Piping (180o elbows)
4.9.1 Most of the heat exchangers are coupled in pairs, such that one 3.5” supply riser pipe supplies two 5’ x 15’ heat exchanger coils with the flow passing through them in series. The connection between paired heat exchanger coils is a fabricated 180o elbow. The contractor shall replace these elbows with 3” Schedule 40 carbon steel pipe, elbows and adapters for grooved fittings. Drawing 46-IMC0119-002 shows the new elbow assemblies to be fabricated and installed. There are 19 locations where the assembly on drawing 46- IMC0119-002 is required. The lower-most heat exchanger in the center column will not be installed while the contractor is on site, therefore the contractor is not required to complete the coupling piping between this heat exchanger and the one immediately above it (to be completed by NRC).
4.10 New Supply Valves
4.10.1 There are 19 existing 3.5” diameter supply valves (globe valves). All of these valves shall be replaced with 3” diameter butterfly valves. The contractor shall remove and dispose of the old valves and flanges, and weld- install new flanges and make-up piping for these valves. The valve installations shall be as per Drawing 46-IMC0119-005.
4.10.2 The contractor shall install all valves and supply all flange gaskets required to do so.
4.11 New Supply Line Weld Outlets
4.11.1 The contractor shall weld-install one ¾” diameter threaded weldolet (branch outlet) above each of the 23 supply valves as per Drawing 46-IMC0119-005. These ports will be used for leak testing, winterising and possibly for sacrificial anodes.
4.12 New Vent Lines
4.12.1 Each of the three columns of heat exchanger coils has threaded piping connected to the top of each column to purge air from the heat exchanger system. The existing arrangement has one outlet per heat exchanger column which are then collected into one pipe that runs down and to the top of the cooling tower. The contractor shall remove this existing piping.
4.12.2 New vent lines shall be installed using 1.5” diameter schedule 40 carbon steel pipe with threaded fittings. Three separate vent lines shall be installed (one per column). The vent lines shall branch off of the outlet for the top heat exchanger in each column and run vertically to the bottom of the settling chamber alongside the existing supply and return piping, pass through the tunnel shell and terminate with a ball valve located approximately at the same height as the existing supply valves.
4.12.3 The air vent lines shall be supported at the top of the vertical run by one hanger, and guided using u-bolts at the same 4 locations as the supply piping (see drawing # 11056, sheet 4). The contractor shall install these pipe supports.
4.12.4 The vent lines shall be finished with one coat primer and one coat oil-based rust paint (white).
4.13 Pneumatic Control Tubing for the Drain Isolation Valves
4.13.1 The new butterfly valves (pneumatically actuated) installed in the drain lines require ¼” plastic tubing for the supply and exhaust of control air. Each of the 23 valves will require an independent supply (control) line.
4.13.2 All of the exhaust ports of the valve actuators in each column shall be connected to a common tube (i.e. one common exhaust line per heat exchanger column).
4.13.3 All of the pneumatic tubing shall be run vertically inside the nearest structural column (14” wide-flange I-beam). All tubing shall be run to the bottom of the column and a coil of 10’ extra tubing shall be left for others to terminate.
4.13.4 The tubes shall be secured to the column using NRC supplied tube guides in 8 locations per column (24 total). Each tube guide requires the contractor to drill and tap two holes for #12 machine screws.
4.13.5 All tubing shall be installed after welding and cutting operations are completed to avoid damage.
4.14 Weld Inspections and Acceptance Criteria
4.14.1 All welding work completed by the contractor shall meet or exceed the visual inspection criteria as per ASME B31.3-2006 table 341.3.2 “Normal and Category M Fluid Service”. Inspection to be conducted by NRC Departmental Representative
4.14.2 In case of disagreement in regards to the visual inspection of certain welds, NRC will hire a qualified independent examiner to review the disputed welds. The result of this third party examination shall be binding.
4.15 Leak Tests
4.15.1 Each of the 23 sections of the heat exchanger shall be leak tested using water at 150 psig. The test shall include all piping and components between the supply valves at the ground level and the newly installed drain valve. Pass criteria: no visible leaks after 10 minutes of full pressure. The contractor may use compressed air to quickly check their work for leaks as needed to avoid delays associated with hydraulic testing. Pneumatic leak tests shall not exceed 25 psig at any time.
4.15.2 Each of the three drain lines (8” vertical columns) shall also be leak tested using water at 150 psig. The test shall include all components from (and including) the 8” isolation valves at ground level to (and including) the newly installed 3” drain valves. Pass criteria: no visible leaks after 10 minutes of full pressure.
4.16 Repairs as a result of failed leak test(s)
4.16.1 New piping, new piping welds, grooved fitting connections and heat exchanger gasket leaks. Leaks in any of these areas are the contractor’s responsibility to repair and re-test.
4.17 Miscellaneous
4.17.1 The contractor shall verify all piping dimensions on supplied drawings before fabricating each pipe assembly to ensure there are no interferences or problems.
4.17.2 All contractor personnel that will be using the mast climbing work platforms shall be trained to do so by the manufacturer of the system (Klimer) or one of their approved partners. The contractor shall be responsible for organizing and paying for this training. A representative for Xxxxxx can be contacted at (000) 000-0000 or xxx.xxxxxx.xxx. This training must be organized to occur no later than 1 week after contract award.
